Market leader by size
Under 10 employees
61.7% of band
This is the largest detected band, with 20,413 UK field services companies and a market led by WordPress at 61.7%. Wix and Cornerstone form the main second tier, with smaller site-builder and open-source systems making up the remainder.
10–50 employees
66.1% of band
The 10–50 employee band includes 7,413 detected companies, with WordPress taking a larger share at 66.1%. Competition is still present, but the gap between WordPress and the next systems is wider than in the under-10 band.
Over 50 employees
75.6% of band
The over-50 employee band is much smaller, at 618 detected companies, and more concentrated. WordPress leads with 75.6%, leaving the rest of the market split across a relatively narrow pool of alternatives.
How CMS usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. 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.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
