Candidate · London associate seats
Secondments: career accelerator or holding pattern?
The wage you keep is the sending firm's. The file you are allowed to own is the host general counsel's. A London client seat is an accelerator only if those two facts are both written down.
Pay versus perimeter.
A London secondment keeps the sending firm's wage while the host in-house desk is priced as in-house counsel. Across 750 structured interviews with London associates and counsel, the split is ownership, not cash.
You keep the firm wage. The host general counsel will not let you sign, instruct, or keep a matter. The CV will carry a logo. Holding pattern — do not trade a year for it.
Pay is not the test. The perimeter is. The paycheck and the invoice are laid out next.

Pay is not the test. The perimeter is.
City pay on an in-house desk.
The wage you take home is not the invoice the host pays. A firm-employed secondee keeps the sending firm's scale. The host general counsel buys a recharge.
Pay is not the test. The perimeter is. The measurable pay fact is still the one a London associate already knows: the sending firm remains the employer, so the wage does not step down to the host in-house scale for the duration of the seat.
The Lawyer, on 4 September 2024, reported that Slaughter and May raised its newly qualified London salary to £150,000 from 1 September 2024, after Freshfields, Linklaters, Clifford Chance, and A&O Shearman had moved to the same base the previous May. That is the wage a firm-employed secondee from those desks continues to draw. It is announced base pay, not a bonus, not a mid-level lockstep, and not a secondment premium — none of those was on a primary page we opened. Freshfields’ UK trainee page, with a 2026 application window, prints the staircase under that cap: year one £56,000, year two £61,000, newly qualified associate £150,000. A&O Shearman’s London training-contract page prints the same three numbers. Herbert Smith Freehills Kramer prints year one £56,000, year two £61,000, and a newly qualified base of £145,000. The seat does not rewrite those grids.
The host desk is a different market. Incomes Data Research, in In-house legal pay in 2025, citing Office for National Statistics provisional data released 23 October 2025, put the newly qualified in-house median at £44,263 across the UK and £57,000 in London. London legal advisers sat at a median of £66,934. Heads of legal earned close to £150,000 at the median, with some surpassing £200,000. Senior in-house legal advisors in that survey typically received a bonus worth 12 percent and a car allowance worth £7,000. The host head of legal, at the median, is paid like a Magic Circle newly qualified associate. The secondee in that person’s team is paid like the firm. That is the awkward arithmetic a chief legal officer sees on the invoice.
Public-body hosts are cheaper still, and they are not client secondments. A Financial Conduct Authority Legal Division posting for a London Commercial Lawyer, dated 20 August 2026, advertised £55,000 to £67,000 for a qualified lawyer, typically newly qualified to three years’ post-qualified experience. The Government Legal Profession’s recruitment page puts Legal Officer roles, generally zero to three years’ post-qualified experience, around £50,000, and Lawyer (Grade 7) roles, generally three or more years, around £60,000. The Bank of England’s legal careers page, updated 31 October 2025, describes an in-house team of around 170 colleagues and says those lawyers do not typically need to record their time. Those are permanent desks. A firm-employed secondee sitting beside them is still on City scale.
Charles Russell Speechlys, on its UK training-contract page, prints a different City: London year one £52,000, year two £55,000, newly qualified £93,000. Milbank’s London careers FAQs print trainee pay of £70,000 then £75,000. The seconded lawyer’s wage is the sending firm’s wage, wherever the host sits. Derived from the 2024 Magic Circle newly qualified base and the 2025 London in-house newly qualified median, a Magic Circle secondee is paid about 2.6 times the host desk’s junior median. That multiple is why a general counsel takes a secondee for a mandate and not as a bargain hire.
What you take homeWhat you are allowed to own
- Firm wage PAYE stays with the sending firm. Your band does not become the host in-house median for six months.
- Host invoice Salary plus employer National Insurance plus pension, then value-added tax on that bundle, unless a genuine joint-employment structure is used.
- Host file The general counsel’s matter. You may progress it. You do not take it with you, and you do not become its owner as a personal client.
The paycheck travels. The host general counsel’s file does not. The cash perimeter is the recharge. HM Revenue & Customs, in VAT Notice 700/34 last updated 31 December 2020, treats a supply of staff as a standard-rated supply on the full consideration, which expressly includes recovered salary, National Insurance, and pension contributions. The section 6 disregard — where certain payments are ignored for value — requires the host to pay the employee directly and to discharge PAYE and National Insurance, and it fails if the placing is done with a view to financial gain. The ordinary law-firm client secondment, in which the firm keeps payroll and recharges cost, sits outside that disregard. The notice page we opened does not print the standard-rate percentage; we do not invent it.
Employer National Insurance on that payroll moved on 6 April 2025. The GOV.UK policy paper on secondary Class 1 contributions, announced at Autumn Budget 2024, raised the secondary rate from 13.8 percent to 15 percent and cut the secondary threshold from £9,100 a year to £5,000 a year until 5 April 2028. The Office for Budget Responsibility yield restated on that page is £23,770 million in 2025–26. That is the Exchequer’s number, not a change in the secondee’s salary. It is a reason for a host chief legal officer to shorten a placement, to refuse a mid-level associate whose base is on a City scale, or to hire permanent in-house counsel on the host’s own median. It is not a reason for the secondee to expect a premium.
Occupation-wide solicitor pay is a third series, and it is not this seat. Incomes Data Research, citing the Annual Survey of Hours and Earnings provisional release of 23 October 2025, reported that median full-time annual earnings for solicitors and lawyers increased by 10.7 percent year on year, against 4.3 percent for all full-time employees. The Office for National Statistics bulletin of the same date states that 2025 estimates are provisional. That growth rate is not a London City-associate series and not a secondee series. Use it only as a reminder that the profession’s published wage and this seat’s recharge are not the same instrument.
We map about 30,000 lawyers in London. The mapping is coverage, not a wage census, and it does not invent a secondee band the SRA and the Law Society do not publish. For sourced in-house pay beyond this page’s host-desk medians, see our in-house counsel salary guide.
The paycheck travels. The host general counsel’s file does not.
The host general counsel owns the client.
The Solicitors Regulation Authority is blunt about who the client is. A secondee sitting inside an in-house team does not acquire a personal following, and does not become the lawyer for the instructing manager.
The client is the organization, not the instructing manager. The Solicitors Regulation Authority’s guidance Identifying your client when working in-house, updated 18 November 2024, puts the duty on the employer as a whole: charity board of trustees, NHS trust board, company board, local-authority council, or, more complex, central government. The solicitor must act in the best interests of the organization, not of a line manager, director, or senior executive. Conversations with colleagues who give instructions are not necessarily confidential from the organization. A secondee who talks about “my business-unit client” is already on the wrong side of that line.
The regulator’s case studies, published 23 July 2026, are the host-desk version of the same perimeter. An in-house team at a regional bank asked to act for both the bank and a named employee in an employment-tribunal claim: dual representation is comparatively rare, and the employer is the existing client. An in-house solicitor moving from a local authority to legal counsel at a construction company that bids on the authority’s projects: ongoing confidentiality to the former client can block acting on the same dispute. A scale-up technology firm pressing a solicitor to approve customer contracts with broad exclusions while the head of legal is on leave: independence sits above the sales timetable. From 2 June 2026 the Solicitors Regulation Authority is a prescribed person under the Public Interest Disclosure Act 1998. A secondee who wants to “be the lawyer for” one division will hit a stop, and that slice of work will go back out to external counsel.
Reserved work is a second fence. If the host is an unregulated organization and the lawyer is its employee, the SRA’s unregulated-employer guidance (updated 25 November 2019) keeps reserved legal services to the public off the desk. A solicitor held out as such, or carrying out reserved activities in-house for the employer, must hold a practicing certificate. Compulsory professional-indemnity insurance is an employer-policy question in that setting, not the SRA minimum-terms policy. The firm-employed secondee is in a different box: the SRA glossary definition of private legal practice includes, without limitation, the provision of such services as a secondee of the insured firm, and the Indemnity Insurance Rules set any-one-claim minima, exclusive of defense costs, at least £3 million where the insured firm is a relevant recognized body or licensed body in respect of SRA-regulated activities, and at least £2 million in other cases.
Supervision does not travel with the pass. The SRA’s effective-supervision guidance records, as good practice, a secondment agreement that sets out supervisory arrangements where day-to-day supervision by the firm is impractical. The secondee remains an employee and the firm retains ultimate responsibility. That sentence is why a host head of legal can direct the work without becoming the solicitor who answers for it, and why a sending-firm supervisor who treats the seat as six months off-book is already in a bad file.
The Court of Appeal restated the litigation half of that fence in The Chartered Institute of Legal Executives (CILEX) v Mazur & others, as reported by the Law Society on 13 April 2026 and in a practice note of 29 April 2026. An unauthorized person may perform tasks within the conduct of litigation for and on behalf of an authorized person if the authorized person retains responsibility; only authorized persons are entitled to carry on the conduct of litigation, one of six reserved activities under the Legal Services Act 2007. The practice note says the definition is narrow — issuing, filing, and serving applications and statements of case — and that much handling of proceedings falls outside it. A disputes secondment into a host that is not an authorized firm cannot put an unqualified colleague in charge of the formal steps. A solicitor with a practicing certificate can carry that reserved activity; the person sitting next to them cannot own it.
The qualification gate at the junior end changed on 1 September 2021, when the Solicitors Qualifying Examination became the route for new candidates. The SRA’s SQE questions-and-answers page, updated 28 January 2026, requires a degree or equivalent, the examination, two years’ qualifying work experience, and suitability. Qualifying work experience must develop the prescribed competences, last at least two years full time or equivalent, take place in no more than four organizations, and be confirmed by a compliance officer for legal practice, a solicitor in the organization, or another nominated solicitor. A client seat during a training contract can be one of those four, if a solicitor confirms it. It does not replace the firm’s own seat rules. The Legal Practice Course route remains open until 31 December 2032 only for people already inside the transition. Junior cohorts now arriving at Magic Circle and City programs are on the examination route.
Credential gates on the sending side are not the host’s gates. Slaughter and May’s training-contract page states that a client secondment is not compulsory, that trainees may apply for an international or client seat, and that trainees who are in the UK on a working visa may not be eligible to apply for client secondments because of visa restrictions. The host’s own legal desk, when it hires permanently, runs a different set: practicing status, post-qualification bands, and, in central government, nationality rules and a minimum 2:1 degree. Government Legal Profession pages also say departments usually expect lawyers to remain in a particular post for three to four years. That is a permanent public-body desk, not a City client seat, and it is the comparison a junior associate should make before treating a six-month placement as a government career.
The practicing-certificate fee for 2025/26, approved by the Legal Services Board and set out in the SRA fee policy updated 30 September 2025, is £396: a regulatory fee of £326 and a compensation-fund contribution of £70, with an administration fee of £48 inside the regulatory fees. A secondee who must hold a certificate pays that whether the pass is in a wholesale bank or a listed consumer-goods group. It is a cost of remaining a solicitor, not a secondment fee.
When a secondment is an accelerator.
Sartori's London interview cohort is the only census we trust on this seat. The public record does not count secondees. What the same cohort tells us is that pay is solved and ownership is not.
A logo on a CV is not a file you owned. That is the finding that decides the title of this page. Across 186 London associates and counsel, drawn from the same cohort, who had sat a client seat in the trailing 24 months, 71 percent said the paycheck never left the firm scale, and 64 percent could not name a matter they were allowed to own at the host.
We have worked the London associate market for more than ten years, for companies staffing in-house desks and for firms that still send people into those desks. A typical permanent hire on that line still fills in 6 to 12 weeks. The client seat is adjacent to that book, not the same product. Of 14 secondment-adjacent files inside the 33 closed searches over a 36-month window — the associate was on a client seat, coming off one, or the host asked for a secondee as the hire — six stalled because the host general counsel would not put ownership language in the letter. That is the number that does not flatter us. We could not convert a recharge into a named file, and we should not have tried to dress it as a search.
Conversion is rarer than the hallway conversation. How far a permanent in-house conversation went, in that same 186, is the funnel below; it is not a public census. A chief legal officer who wants a permanent lawyer will open a requisition. A chief legal officer who wants surplus capacity will take a secondee and keep the letter thin.
Direct testimony matches the split. A four-year post-qualified financing associate, back from six months in a wholesale bank’s in-house team, told us: “I came back with a client name on my CV and no file I could describe as mine.” A head of legal at a listed consumer-goods group, describing why the letter stays thin, said: “I will take a firm associate for six months. I will not let them sign.” A general counsel at a wholesale bank put the invoice version: the recharge is cheaper than a permanent hire until National Insurance and value-added tax land on the bill, at which point the seat shortens. Those are roles and organization types, not names.
Three composites from that book, anonymized, show the same fork. First: a four-year post-qualified financing associate, six months at a wholesale bank, used on panel-management overflow. The host head of legal would not name a facility or a credit file as the associate’s. The person returned able to name the bank and not the work. Holding pattern. Second: a mid-level commercial associate at a listed consumer-goods group, given a named class of supplier contracts, with the host general counsel as the solicitor who would confirm qualifying work experience. The CV could describe the contracting file without the brand. Accelerator. Third: a counsel-level placement through a personal-services company at a private-equity fund manager. The host delayed the Status Determination Statement. The 45-day disagreement clock started. That is the on-demand product, not a firm-employed client seat, and it stalled as a search.
London associate mandate telemetry still records a 35 percent counter-offer incidence across the 33 closed searches over three years. A client seat does not immunize the associate who later tries to leave. Firms still counter at the program rate. The people who used the seat as a shop window, then came to us for a permanent in-house move, walked into the same counter-offer dynamic as everyone else on this line. Sartori’s quarterly survey since 2019, in its 2025 second-half London associate wave, found that 58 percent of those who had sat a client seat would repeat it only if the letter named a file owner other than the host general counsel.
The New York interview cohort hears a different first step: a permanent in-house hire, not a firm-payroll placement. Across 1,675 structured interviews with New York lawyers, the pay-versus-perimeter split we record in London does not appear in the same shape, because the typical first in-house step there is a hire onto the company payroll. That is contrast, not a second London census.
Two limits on what we can see. First, contractor-style on-demand placements often sit in personal-services companies; our London mapping and mandate telemetry undercount that product, and a page that pretended otherwise would be a cleaner story than the file. Second, published program rules are not fill rates. Freshfields aims to send all trainees on a placement in the final six months, to a global office or a client. Slaughter and May says the client seat is not compulsory. Herbert Smith Freehills Kramer offers 55 secondments each year across international offices, client desks, and internal in-house teams — 55 is all three types, not client-only, and not associate-only. Milbank’s London FAQs say client seats follow business need and, on the page opened, arise after qualification, with an intake aim of approximately 15 or 16 trainees a year. Charles Russell Speechlys names current client hosts by type: a private-equity fund manager, a commercial bank, and an in-house commercial team for a large construction client. Those are the desks. They are not a count of how many London associates are out on a given Wednesday.
Firm payrollHost payroll
- Firm-employed seat You remain the firm’s employee. The host general counsel directs the work. This page’s subject.
- On-demand placement Usually a personal-services company. Off-payroll status sits on the host. Different product.
- Permanent in-house The host is the employer. The chief legal officer owns the budget. A different page.
The statutes that fill the desk never mention a secondee.
Failure to prevent fraud, Companies House identity verification, and a thin listing cycle rewrite the host general counsel's file. They do not publish a secondment statistic.
Demand for a London client seat is not one market. It splits between a firm-employed placement, whose cost moved with employer National Insurance on 6 April 2025, and a contractor placement through an intermediary, which has sat under off-payroll rules since 6 April 2021. The work that fills the host desk is being rewritten by statute that does not mention the seat: failure to prevent fraud from 1 September 2025, and Companies House identity verification from 18 November 2025. Those rules load commercial, governance, and company-secretarial work at large organizations — which is where a secondee is physically put.
The Home Office brought the failure-to-prevent-fraud offence, created by the Economic Crime and Corporate Transparency Act 2023, into effect on 1 September 2025. A large organization can be criminally liable where an employee, agent, subsidiary, or other associated person commits a fraud intending to benefit the organization. The Home Office guidance, updated 10 October 2025, applies the offence to large incorporated bodies, subsidiaries and partnerships, large incorporated not-for-profits, and incorporated public bodies; it does not apply to police forces or government departments. A large organization meets two or three of: more than 250 employees; more than £36 million turnover; more than £18 million in total assets, tested on the financial year preceding the year of the base fraud. From that date, large London corporates, banks, fund managers, and incorporated charities need documented fraud-risk assessment and procedures. That is work for in-house commercial, investigations, and governance lawyers, and for the external firms that send people into those teams. It is work for counsel who can own a risk assessment, not for a first-seat trainee used only for document review.
Companies House identity verification became compulsory for new directors and people with significant control on 18 November 2025, with a 12-month transition for existing directors tied to the next confirmation statement. The 5 August 2025 press release estimates 6 to 7 million individuals will need to verify by mid-November 2026. Voluntary verification had been open since 8 April 2025; more than 300,000 individuals had verified in that voluntary period by the date of the release. Verification can be done free via GOV.UK One Login or through a solicitor acting as a Companies House identity-verification intermediary. A YouGov business Omnibus, fieldwork 16–25 June 2025, 1,007 decision makers, found 60 percent aware of the new requirements and 81 percent supportive. That is a governance filing calendar inside the legal team, not a new secondment program. A secondee sitting in a commercial in-house team will meet it.
The equity-capital cycle that used to justify a corporate secondee is still thin. The Financial Conduct Authority’s listing overhaul, policy statement 11 July 2024, took effect on 29 July 2024: a single commercial-companies category, streamlined eligibility, removal of votes on significant or related-party transactions, flexibility on enhanced voting rights, shareholder approval retained for reverse takeovers and cancellation. The Authority notes the UK Listing Review finding that listed companies in the UK had fallen by about 40 percent from a recent peak in 2008, and that between 2015 and 2020 the UK accounted for only 5 percent of initial public offerings globally. That is a change in the content of a corporate seat — less circular work, more disclosure and sponsor work around a simpler eligibility test. It is not evidence that more secondees are required.
Issuers de-listing equity securities were 50 in 2025 and 69 in 2024 on the same FCA table. Main Market total market capitalization, taken by the FCA from London Stock Exchange public information, was £4,121,991.7 million in 2025 and £3,446,028.8 million in 2024. EY-Parthenon, on 6 January 2026, counted a different universe: 23 companies listed on the London stock market in 2025 raising £2.1 billion, against £777.7 million from 18 issuers in 2024; nine on the main market and 14 on the Alternative Investment Market. Do not add the EY series to the Official List series. A corporate or financing secondee in London is staffed against a live mandate calendar, not against a restored 2021 listing boom. A quiet issuance year removes the reason to keep a junior corporate associate at a host through a long placement.
Structural demand for the lawyers who are sent is the London share of English-law work, not a secondment statistic. The Law Society’s International Data Insights Report, 9 September 2025, states that around 40 percent of global business and financial transactions are governed by English law; legal-services exports rose to £9.02 billion in 2024, from £6.27 billion in 2020; the London Commercial Court delivered 196 written judgments between October 2023 and September 2024; between April 2024 and March 2025, 61.7 percent of litigants came from outside the United Kingdom; 78 percent of London Court of International Arbitration cases were governed by English law in 2024; the London Maritime Arbitrators Association handled 1,733 new cases in 2024. Queen Mary University’s 2025 International Arbitration Survey: 34 percent of respondents chose London as preferred seat. A fall in issuance or a rise in permanent in-house headcount changes whether the host asks for a secondee or hires. These figures do not count secondees.
The permanent host profession is growing, and a firm-employed secondee is still counted in private practice. The Law Society Annual statistics report 2023, covering August 2022 to July 2023, put solicitors working in-house at 35,738, 22 percent of practicing-certificate holders, up from 19 percent in 2014; private-practice share fell from 69 percent to 59 percent over that span. The Law Society career-options page dated 18 December 2025 states that in-house practitioners now make up 26 percent of the profession, with over 95,000 solicitors in private practice. TheCityUK’s 9 December 2025 report page states the in-house share at 25 percent, UK-based legal-services revenue at £52.3 billion in 2024, and London legal-services employment at 128,000 in 2023 data. The SRA’s July 2026 row counts 178,428 practicing solicitors in England and Wales. A client secondee who remains employed by a law firm is in the private-practice column, not in that in-house share. Growth in the in-house share is the permanent host desk.
Read the letter before you pack the pass.
Published programs cap the seat. The secondment agreement decides whether those months are a file or a recharge. If the letter is silent on ownership, the seat is a holding pattern.
If the letter is silent on ownership, the seat is a recharge. Duration rules are the easy part, and they are public. Clifford Chance’s Grow with us page (asset paths dated 2026) says many associates can spend time at an international office or at a client, and that on a client secondment they are involved in the client’s everyday work. Published caps on that page are for office-exchange programs, not for the client seat: European exchange, junior to mid-level associates including London, four-month maximum; antitrust exchange, six-month maximum; technology exchange, minimum two years’ qualification experience, six-month maximum. Linklaters’ training-contract page describes four six-month seats and the chance of an international or client placement. A&O Shearman runs four six-month rotations in finance, corporate, disputes, and energy, natural resources and infrastructure, and invites trainees to explore an international or client seat. Freshfields moves seats every three months.
Of 8 signed client-secondment letters in our London associate telemetry over three years, four were cut at month 4 when the host mandate ended. That is why the letter needs a kill switch in writing, and why a six-month headline with a four-month reality is a holding pattern even when the paycheck was never in doubt. For an associate attorney weighing the year, the tests below are the operating list. For a host head of legal, they are the same list read from the other side of the invoice.

On the firm-employed seat, payroll never leaves the sending firm. Diligence the letter, not the host brand.
- Stay on the firm scale. Confirm PAYE, bonus treatment, and that the host invoice is a recharge, not a new wage.
- Name the file in the agreement. A host general counsel who will not write it down is hiring surplus capacity.
- Keep a sending-firm supervisor. SRA guidance leaves ultimate responsibility with the firm even when day-to-day control sits with the host.
- Do not count on conversion. A permanent in-house conversation is a bonus. If that is the goal, run a real search — our in-house counsel recruiting desk and the network-versus-search note are the adjacent pages.
On the on-demand seat, the host is usually a medium or large client with an off-payroll duty. Diligence status, not the logo.
- Read the size tests. Off-payroll rules from 6 April 2021 apply to all public-sector clients and to private and voluntary-sector bodies that meet two or more of: annual turnover more than £10.2 million; balance-sheet total more than £5.1 million; more than 50 employees.
- Demand the Status Determination Statement. The client must take reasonable care, issue reasons, and respond to disagreement within 45 days. Small private-sector clients do not determine status; the intermediary does.
- Do not relabel labor as a managed service. HMRC’s Employment Status Manual ESM10010 says working practices decide: who controls the worker, who benefits, who bears risk, whether the worker is integrated. A secondee in the host in-house team, taking the host’s instructions, is the fact pattern the manual treats as labor supply.
- Remember the regulatory client. The Law Society’s 2 October 2020 guide still treats you as a lawyer of the host organization. Primary duty is to that client, not to the personal-services company that found the placement.
Firm-employed client seat
The sending firm remains the employer, keeps PAYE, and recharges salary plus on-costs. You sit inside the host in-house team. The host general counsel directs the work. You do not become in-house counsel.
On-demand placement
A legal-services business places you, often through a personal-services company. Off-payroll rules from 6 April 2021 sit on medium and large hosts. The Law Society still treats you as a lawyer of the host organization.
Permanent in-house hire
The host is the employer. Pay is the in-house scale. The chief legal officer owns the budget. This is the move our in-house playbook covers — not a secondment with a nicer title.
Sartori & Partners maps lawyer profiles globally on a continuous program that has run quarterly market surveys since 2019, covering nearly 1.5 million profiles. The London associate line is one city book inside that program, not a second census. If you want a confidential read on a letter you have been handed — or a host general counsel wants a permanent in-house hire instead of another recharge — that is how we work, and it is the associate search and in-house desks above. The client seat is worth taking when the perimeter is written down. It is a holding pattern when the only fact in the letter is the paycheck.
Questions London associates ask about client seats
Is a London secondment a career accelerator or a holding pattern?
It is an accelerator only when the host general counsel lets you own a named file; otherwise it is a holding pattern on City pay. Sartori’s London interview cohort splits on ownership, not on the paycheck. Read the letter, not the logo. The permanent in-house move is a different page — see our in-house transition playbook.
Does a secondee keep City pay while sitting with in-house counsel?
Yes: The Lawyer reported on 4 September 2024 that Magic Circle newly qualified London base reached £150,000, which a firm-employed secondee keeps. Incomes Data Research in 2025 put the London in-house newly qualified median at £57,000. The host’s invoice is larger than either number: HM Revenue & Customs treats a salary recharge as a standard-rated supply of staff on the full consideration, and from 6 April 2025 employer National Insurance on that payroll sits at 15 percent above a £5,000 secondary threshold. The secondee’s take-home is the firm scale. The host general counsel pays the recharge.
Can a client seat convert to a permanent in-house counsel role?
Sometimes: of 186 London associates in our cohort who had sat a client seat, 9 percent received a written in-house offer. No public series counts conversions. Treat conversion as a bonus, not the plan. If the goal is a general counsel track, start with the firm-to-GC read.
How is a firm-employed seat different from an on-demand legal placement?
They are different employers: the firm-employed seat stays on the firm’s payroll; the on-demand seat is usually a personal-services company under off-payroll rules since 6 April 2021. The Law Society’s 2 October 2020 guide describes the contractor model: contracts sit with the legal-services business and the lawyer’s company, and the host is still the regulatory client. Medium and large London hosts must issue a Status Determination Statement and answer disagreement within 45 days. Do not shop the two seats as grades of the same product.
How long does a London client seat usually last?
Published London programs cap many associate exchanges at four to six months; one Magic Circle careers page sets a four-month European maximum. Trainee client seats are commonly one of four six-month rotations. Freshfields’ UK trainee page, with a 2026 application window, moves seats every three months and aims to send every trainee on an office or client placement in the final six months. Duration is a cap, not a career.
What should I ask the host general counsel before I go?
Ask three questions of the host general counsel: who the client is, which file you own, and who signs your supervision. The Solicitors Regulation Authority’s in-house guidance, updated 18 November 2024, makes the client the organization, not the instructing manager. A disputes seat also has to survive the Court of Appeal’s Mazur holding, as restated by the Law Society on 13 April 2026: only an authorized person may carry on the conduct of litigation. If the letter is silent on those three points, you are being paid to sit, not to own.
Pay notices, tax manuals, and regulator guidance.
Announced City bases and in-house medians come from The Lawyer and Incomes Data Research. Recharge and off-payroll mechanics come from HMRC. Ownership and reserved work come from the SRA and the Law Society. Listing and fraud calendars come from the FCA and the Home Office. Cohort reads come from Sartori's London associate program.

Official List IPO counts are the Financial Conduct Authority series; London listing proceeds are the EY-Parthenon main-market plus AIM series. They are different universes and are not additive. In-house share is 22 percent in the Law Society 2023 census table, then stated at 25 percent (TheCityUK, December 2025) and 26 percent (Law Society career-options page, December 2025) without a new headcount. A firm-employed secondee remains in private practice for those counts.
The permanent move is a different page.
This article owns the client seat. The in-house playbook owns the hire onto the host payroll. The GC piece owns the identity shift if that is the real destination.

We run the London associate line and sit with host general counsel teams on the permanent hire that sometimes follows. Quiet, evidence-led, and willing to say walk.
