The pattern is consistent across company size bands. WordPress has 66.2% of the 17,797 detected companies with under 10 employees, 70.4% of the 5,752 detected companies with 10–50 employees, and 79.5% of the 488 detected companies with over 50 employees.
The long tail is broad rather than deep: 37 systems are detected overall, with 29 further systems covering 873 companies between them. That leaves most detected usage concentrated in a small set of general-purpose CMS and website-builder systems, especially among construction firms with median headcounts around 4 to 6 across the profiled systems.

Market leader by size
Under 10 employees
66.2% of band
This is the largest detected band, with 17,797 construction companies and a market led by WordPress at 66.2%. Wix, Squarespace and other website builders sit mainly in this small-employer market alongside specialist and agency-built sites.
10–50 employees
70.4% of band
The 10–50 employees band covers 5,752 detected companies, with WordPress taking 70.4%. Competition remains concentrated among the same general CMS and website-builder systems, with fewer companies spread across the smaller platforms.
Over 50 employees
79.5% of band
The over 50 employees band is much smaller, at 488 detected companies, and WordPress has 79.5%. Larger construction firms in this view appear less fragmented by CMS choice than smaller firms.
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.
