CMS Used by UK Renewable Energy Companies: Market Share (2026)

Updated June 2026

Shows detected CMS market share across 2,729 UK renewable energy companies with a detectable CMS, with WordPress the largest system at 73.4% (2,003 companies).

Among 3,570 trading UK renewable energy companies, 2,729 have a detectable CMS. WordPress accounts for 73.4% of detected use (2,003 companies), leaving a sizeable gap to Wix at 10.7% (292), Squarespace at 5.7% (155), and Webflow at 3.7% (102).

The same pattern holds across the employee bands. WordPress leads under 10 employees with 73.2%, 10–50 employees with 73.6%, and over 50 employees with 76.2%, so the market does not appear to split sharply by company size.

Market leader by size

The leading CMS system shifts with company size: among UK Renewable Energy with under 10 employees, WordPress leads at 73.2% of the 1,992 with a detectable system; among UK Renewable Energy with 10–50 employees, WordPress leads at 73.6% of the 674 with a detectable system; and among UK Renewable Energy with over 50 employees, WordPress leads at 76.2% of the 63 with a detectable system.

Under 10 employees

WordPress

73.2% of band

Micro renewable energy companies make up the largest detected band, with 1,992 companies. WordPress leads with 73.2%, while the remaining share is spread across hosted site builders and smaller CMS choices.

10–50 employees

WordPress

73.6% of band

The 10–50 employee band contains 674 companies and still centres on WordPress, at 73.6%. Wix, Squarespace, Webflow and the long tail compete for the rest rather than changing the overall pattern.

Over 50 employees

WordPress

76.2% of band

Larger renewable energy employers are a smaller group, with 63 companies detected. WordPress has the highest share here too, at 76.2%, suggesting larger headcount does not, by itself, move this category away from the main CMS.

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.

How many UK Renewable energy companies have a detectable CMS?

What is a CMS?

A CMS is the software layer used to create, edit, publish, and manage a company website. For UK renewable energy companies, it typically handles marketing pages, project information, news, contact forms, and other public-facing web content without requiring every change to be coded manually.

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 Renewable energy companies, WordPress or Wix?
