Key facts
About 1% of the trading cohort reports turnover above £5M (109 of 35,921 firms) — the rest sits below that revenue band.
15% of the cohort was incorporated since 2022 (5,477 firms), so a sizeable share is in its first few filing cycles.
The FRC is the Competent Authority for public supervision of UK statutory auditors under the Statutory Auditors and Third Country Auditors Regulation 2016.
Statutory auditors and audit firms are registered and supervised through four Recognised Supervisory Bodies.
Registered statutory audit firms fell from 5,007 in 2020 to 3,760 in 2024, a 24.9% decline over five years.
FRC 2025 data reports more than 408,000 members of the surveyed accountancy bodies in the UK and Republic of Ireland, compared with more than 623,000 worldwide.
Student numbers were under 155,000 in the UK and Republic of Ireland and under 585,000 worldwide.

How this list is built
Data sources
This list is built from UK Companies House filings, XBRL accounts data, and semantic analysis of each company's public website. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Classification
Rather than relying solely on SIC codes, Firmbase classifies each company semantically: the company's website is crawled, an AI model reads what the company actually sells, and the company is placed into the relevant industry and subsectors. SIC codes are used as one signal but not the only one. This means a company that registered under a generic SIC code but pivoted into (for example) fintech is correctly identified as fintech, not as its original SIC category.
Freshness
The underlying company data is refreshed from Companies House continuously; filings appear in the list within days of submission. The curated list ordering is regenerated when the underlying data moves meaningfully (company count changes by more than 5%, a new company enters the top-ranked segment, or the filed-revenue numbers for the top firms change). You can see the last-updated timestamp near the top of the page.
