Companies Using Concrete CMS in the UK: 403 Active Firms (2026)
Web CMS adopters in the UK run content-managed public websites for publishing, marketing, service delivery and customer support.
Adoption tends to sit with organisations that need a managed public site, not just a brochure presence. For its users, the CMS sits between marketing, web operations and customer support: editing pages, routing forms, publishing service information and giving non-developers controlled access to public content. Running it usually signals an in-house owner for the website, some budget for maintenance, and a need to join content workflows with analytics, anti-spam controls or customer-service processes. The buying centre is often a marketing or operations team, with technical oversight supplied by a digital agency or a small internal web team.

UK adoption is a compact specialist footprint: 403 active UK trading companies are running this CMS, with total reported headcount of 1,807 people. The commercial base is mixed rather than uniformly mid-market; many appear closer to small trading businesses, despite the presence of some larger adopters. Sector exposure is tilted towards service and asset-heavy categories, including wealth management, construction, insurance, advanced manufacturing and field services. That mix fits a CMS used for client acquisition, branch or site information, support forms and regularly updated public content, rather than for online retail alone.
UK GDPR and ICO expectations matter where public websites collect contact details, account information, analytics identifiers or support requests. Public sector website projects add accessibility duties: services need to be usable by disabled people, accessibility statements have to be published, and legal responsibility remains with the public body even when operation is outsourced. Procurement therefore tends to focus on audit trails, hosting arrangements, cookie governance, form handling and evidence that content changes can be controlled after launch. For private-sector adopters, the same issues usually appear through risk reviews and contract clauses rather than a CMS-specific regulator.
Adoption appears steady rather than fashion-led. The installed base tends to suit organisations that want editable public-service or client-acquisition sites without rebuilding their whole web stack around enterprise suites. Pressure to migrate is more likely to come from hosting age, security maintenance, accessibility remediation and integration with analytics or customer-service workflows than from content management fashion. Agency consolidation may also matter: when outsourced web operators standardise their stacks, smaller adopters often follow the maintenance path set by their supplier. That points to gradual churn, with retention more likely where editorial control and compliance evidence remain part of the buying case.

Key facts
About 5% of the trading cohort reports turnover above £5M (21 of 403 firms) — the rest sits below that revenue band.
3% of the cohort was incorporated since 2022 (15 firms), so a sizeable share is in its first few filing cycles.
32.0% of the cohort also run a bot-screening service, while 30.8% run a web-analytics tag and 28.8% use a CDN or site-security layer.
Wealth Management is the largest detected sector tag at 15.9%, followed by Construction at 12.2% and Insurance at 10.9%; tags overlap, so these shares should not be read as a market split.
Sites that process personal data sit under UK GDPR and the Data Protection Act 2018, with the ICO as the relevant data-protection regulator.
Public sector website and app projects must meet the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018, including WCAG 2.2 AA where applicable and an accessibility statement.
The UK Business Data Survey 2024 estimated that 68% of UK businesses had a website, giving CMS, maintenance and web-build suppliers a broad but not CMS-specific demand base.

How Concrete 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.
Concrete CMS is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
