Under 10 employees

WordPress

72.6% of band

Under 10 employees contains 17,289 companies, the largest size band here, and WordPress holds 72.6%. This is the small-operator end of field services, where Wix, Duda and Squarespace are the main alternatives across the wider market rather than a separate scale-led cluster.

10–50 employees

WordPress

72.9% of band

10–50 employees covers 6,710 companies, with WordPress at 72.9%. These are larger service teams, but CMS usage remains close to the under-10 pattern, with the same overall challenger set sitting well behind WordPress.

Over 50 employees

WordPress

78.2% of band

Over 50 employees is a much smaller band at 596 companies, and WordPress rises to 78.2%. The larger-employer segment looks more concentrated than the smaller bands; no other system leads any band.

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 field services companies?

How many UK field services companies have a detectable CMS?

What is a CMS?

A CMS, or content management system, lets UK field services companies create, edit and publish website content without rebuilding the site each time. For this market, it typically supports service pages, coverage-area pages, contact forms and quote-request journeys.

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 field services companies, WordPress or Wix?

WordPress: 17,906 detected companies versus 3,103 for Wix, of the 24,595 UK field services companies with a detectable CMS.
