Under 10 employees
69.4% of band
This is the largest band, with 2,696 UK media companies and a 69.4% WordPress share. The remaining use is spread across smaller-site systems such as Squarespace, Wix and Webflow, plus the wider long tail.
10–50 employees
67.9% of band
This mid-sized band contains 716 companies, with WordPress still ahead on 67.9%. Competition is more visible from hosted and design-led CMS options, although no named system is close to WordPress in the overall market.
Over 50 employees
74.1% of band
Only 54 detected companies sit above 50 employees, and WordPress has its highest band share here at 74.1%. The small base means each alternative system represents only a handful of larger media employers.
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.
