London Private Equity Lateral Market 2026: The Largest Firms Hire

The London private equity lateral market is a big-firm market, more so than private equity as a whole and more so than London as a whole. Sartori & Partners data show 165 private equity lawyers joining a new firm in London in the 12 months to October 2026, and 83.5% of them joined a firm of 1,000+ lawyers. Across the practice as a whole that share is 71.6%; across every London practice it is 68.5%. The field of buyers is narrow too: the top 10 hirers took 44.8% of individual hires, against 22.8% across London. For a firm planning its next London private equity hire, these two facts decide who it is bidding against.

Firm size is where this market breaks from both of its parents. In the Sartori & Partners lateral database, 83.5% of London private equity moves in the last 12 months went to firms of 1,000+ lawyers. That is 11.9 points above private equity across the market and 15.0 points above London as a whole. Firms of 400-999 lawyers took 15.2% of the London private equity moves, against 16.4% for the practice and 24.2% for London. Together the two larger size classes took 98.7% of the London private equity moves, against 88% for the practice and 92.7% for London.

The tilt is not a one-year reading. Over three years, 84.5% of London private equity laterals joined firms of 1,000+ lawyers, against 69.9% for the practice and 67.7% for London. The gap with London is the telling one. Mid-size firms of 400-999 lawyers took 26.3% of London hiring over three years, but only 14.3% in private equity. A firm of that size hiring private equity lawyers in London should assume that most of its candidates are also talking to a much larger firm, and build its offer around what a larger platform cannot give: a faster route to the partnership, a smaller team, a client role from the first year.

The size of the firm a lawyer left tells the rest of the story. Over three years, 77.3% of London private equity laterals had left a firm of 1,000+ lawyers, while 84.5% joined one. The largest firms took in a share 7.2 points larger than the share they released. Across the practice as a whole the two shares sit 3.0 points apart, with slightly more lawyers leaving the largest firms than joining them. For London across practices the two shares match: 67.7% joined a firm of 1,000+ lawyers and 67.7% left one.

Smaller firms supply less of this market than they do elsewhere. Firms of 150-399 lawyers and under 150 lawyers supplied 7.8% of London private equity laterals over three years, against 11.6% for the practice and 12.4% for London. Firms of under 150 lawyers alone supplied 5.4%, close to the practice's 5.8% but below London's 8.9%. On the joining side, the two larger size classes took 98.8% of the moves over the same three years. For a large firm, the boutique bench is small, and its peers draw on it little. For a smaller firm, the same figures are a retention signal: when its private equity lawyers move within London, they join a larger firm.

Hiring here runs through a narrower group of firms than in either parent market. Sartori & Partners data count 54 firms that hired a private equity lawyer in London in 12 months, against 180 firms hiring in London across practices and 280 hiring private equity lawyers across the market. The top 10 hirers took 44.8% of individual London private equity hires, against 27.0% for private equity across the market and 22.8% for London across practices. That is 2.0 times the London figure. Over three years the top 10 took 35.4%, against 23.8% for the practice and 21.4% for London, so the pattern holds over the longer window.

The list above ranks hires at every level and counts individual hires, not team moves. Latham & Watkins heads it, in the 11-20 band. Partners made up 30.9% of London private equity moves in 12 months, against 38.1% for the practice and 29.3% for London. Partner volume held steady: 54 London private equity partner moves in the settled window against 54 a year earlier, a flat reading. Private equity partner hiring across the market rose 16.1% over the same window, and London partner hiring across practices held flat (+1.3%). Over three years, the partner list below is headed by Paul, Weiss, Rifkind, Wharton & Garrison, in the 6-10 band. A firm that wants a London private equity partner is bidding in a pool that is not growing, against a short list of large firms that take a large share of the hires.

Volume does not explain the big-firm tilt. London private equity hiring held flat (+2.3%) in the settled 12 months to September 2026, with 175 moves against 171. Private equity hiring across the market rose 14.9% over the same window, to 1,255 moves from 1,092. London hiring across practices held flat (-2.5%), with 1,353 moves against 1,387. London private equity followed its city, not its practice.

The yearly count moved from 127 in 2023 to 180 in 2025, with 135 in 2026 to October. London now holds 13.2% of private equity lateral moves across the market, against 15.1% over three years. Within London, private equity accounts for 12.7% of moves, against 12.3% over three years. The demand is steady, not rising, so a firm that wants more London private equity lawyers will take them from another firm's bench rather than from new demand.

Size sets the field. With 83.5% of London private equity laterals going to firms of 1,000+ lawyers, against 68.5% for London and 71.6% for the practice, a firm of 1,000+ lawyers competes mostly against firms of its own size. Platform is not its edge here; partner economics, sponsor relationships and team fit are. A firm of 400-999 lawyers, which took 15.2% of this market against 24.2% of London hiring, should target lawyers whose next step is not a larger firm: those who want a partnership sooner or a bigger role on a smaller team.

Every search here meets the same few buyers. With 44.8% of individual hires going to the top 10 hirers, the lawyers a firm approaches are often the ones those firms are working too; move early and with a clear business case. Look at the supply side too: 5.4% of laterals came from firms of under 150 lawyers, against 8.9% across London practices, so the boutique bench in this practice is thinner than the city's. And do not wait for volume to help: London private equity hiring held flat (+2.3%) while the practice across the market grew.
