Methodology

How tiers are assigned

Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.

Market scope

50–99 firms earn a tier in United Kingdom within this scope (banded).

Disclosures

Firm names used nominatively (factual). All counts shown as bands, never precise headcounts. No firm logos. Report an error via the site contact form.
