Key facts
15% of the cohort was incorporated since 2022 (9 firms), so a sizeable share is in its first few filing cycles.
Startup is a lifecycle and size tag rather than a separately regulated UK industry; permissions depend on the activity being carried out.
Companies House administration still applies, including confirmation statements and, for some filers, GOV.UK One Login identity verification before filing.
Sector-specific permissions remain relevant for regulated financial services, energy supply, aviation, healthcare or legal activities.
The UK had 5.5 million private-sector businesses at the start of 2024, including 5.45 million small businesses with 0 to 49 employees.
ONS reported 2.725 million UK businesses registered for VAT and/or PAYE as of March 2024, down 0.1% from March 2023.

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.
