The catalogue includes the obscure firms as well as the famous ones. Filter it by activity, structure or metric; add or remove a firm; watch the chart, totals and table recalculate. A ★ marks the ten firms examined most closely in the series.
Figures filed in another currency are converted to GBP at €/£ 0.85 and $/£ 0.78. Before display rounding, the 30 positive turnover rows total £2.4418bn; their year-ends run from July 2024 to December 2025. This is gross reported turnover for selected legal entities. It includes non-economics work inside broad and litigation consultancies, so it is neither UK sector revenue nor a market floor.
“Members” and “top earner” come from filed LLP accounts, or from Ltd-company accounts that disclose an equivalent partner or member figure. “Staff” means average headcount where disclosed. The Fraser of Allander Institute, whose structure is “Other”, sits outside both the LLP and Ltd chips; choose “All” to see it.
The explorer has no turnover figure for Cebr or the named overseas, parent-filed and sub-brand practices: BDO, Deloitte, PwC, Grant Thornton, RSM economics arms, PA Consulting, E.CA and Fraser of Allander. Several also lack headcount. They remain in the catalogue and table as “—”.
“Est.” means the recorded brand-founding year for 24 catalogue rows, including NERA 1961, CRA 1965 and PA 1943; for the other 66 it means the UK incorporation year. The explorer therefore shows FTI 2012, AlixPartners 2010, A&M 2007, Cornerstone 2014, ICF 2001, EIU 1983, Ecorys 1982 and AFRY 1991. The project ledger reconciles each firm's Companies House-derived facts.
