Companies Using Blocksy in London: 92 Active Firms (2026)
London companies running a detected CMS theme on their public websites use templated front-end design for corporate, retail and service pages.
Adoption usually sits with marketing, owner-manager and agency-led web teams rather than central IT departments. A theme in this part of the stack handles layout, reusable page patterns and storefront or service-page presentation, so its use tends to signal a company that wants a maintainable public site without commissioning a bespoke front-end build. Buyers are mostly small and mid-market organisations in commercial services, trades, construction, healthcare and distribution, with occasional larger revenue businesses. Engagements are usually site redesigns, template refreshes, content migrations or maintenance retainers, not enterprise platform programmes.

London has 92 actively trading companies running the detected theme, giving the capital a small but observable adoption base rather than a broad enterprise software cohort. Reported headcount totals 777 people across firms that disclose staff numbers, which points towards owner-managed and agency-served websites as much as internal digital departments. Commercial services and operational sectors account for much of the visible footprint, including Field Services & Trades at 17.4%, Construction at 16.3%, Wholesale & Distribution at 12.0% and Healthcare Provider at 12.0%.
Public-site technology creates a fairly ordinary governance problem for London firms: the theme may be low-cost to adopt, but it sits close to customer-facing content, enquiry forms, analytics tags and cookie consent. Procurement is often handled through web agencies or retained freelancers, so accountability for updates, accessibility checks and plugin permissions can sit outside the company’s main technology function. For service and healthcare-facing sites, content accuracy and privacy controls matter more than the theme itself, particularly where forms collect personal details or route prospects into sales and booking workflows.
Adoption appears likely to remain tied to redesign cycles rather than formal technology programmes. Theme users tend to keep the stack while the website is doing an adequate job, then revisit it when performance, content governance or agency support becomes awkward. Some may move towards more bundled site builders; others will keep content-managed sites because they offer enough control without a custom build. The cohort’s small-business skew suggests steady churn, with replacement decisions shaped by maintenance burden, search visibility and the availability of people who can keep the site current.

Key facts
About 3% of the trading cohort reports turnover above £5M (3 of 92 firms) — the rest sits below that revenue band.
9% of the cohort was incorporated since 2022 (9 firms), so a sizeable share is in its first few filing cycles.
100.0% of the London cohort also shows the underlying CMS, while 65.2% also run a page-builder layer, pointing to relatively standardised site-build patterns rather than fully bespoke front ends.
Analytics coverage is uneven: 42.4% show a web-analytics tag, compared with 29.3% showing an SEO plug-in and 28.3% showing CDN or security tooling.
Service-sector use is visible, with field services and trades at 17.4% and construction at 16.3%; wholesale and distribution and healthcare providers each account for 12.0%.
Cookie-consent tooling appears on 19.6% of sites, and the same share show spam-prevention widgets, suggesting a sizeable minority have added basic compliance or form-protection layers.

How Blocksy 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.
