How CMS usage is detected

Methodology

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.

Frequently asked questions

What is the most-used CMS among UK construction companies?

WordPress is the most-detected CMS among UK construction companies, with 73.1% share (16,223 of 22,187 companies with a detectable system), ahead of Wix (11.7%) and Squarespace (5.2%).

How many UK construction companies have a detectable CMS?

22,187 of 241,271 actively-trading UK construction companies (9.2%) have a CMS detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.

What is a CMS?

A CMS is the software used to create, edit and publish website content. For UK construction companies, it typically supports service pages, project information, accreditations, enquiry forms and local contact details without requiring every update to be coded from scratch.

How is CMS usage detected?

Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.

Which has more UK construction companies, WordPress or Wix?

WordPress: 16,223 detected companies versus 2,597 for Wix, of the 22,187 UK construction companies with a detectable CMS.

What is the best CMS for UK construction companies?

The directory reports observed CMS usage rather than recommendations, so there is no single best CMS here. WordPress accounts for 73.1% (16,223) of the 22,187 detected CMS users, ahead of Wix at 11.7% (2,597), Squarespace at 5.2% (1,143) and Duda at 3.4% (755). By size band, WordPress leads under 10 employees at 72.6% of 16,237 companies, 10–50 employees at 73.9% of 5,474, and over 50 employees at 81.1% of 476.
