Companies Using iThemes in London: 166 Active Firms (2026)
London companies running CMS plugins on their websites use add-ons for security, analytics, forms or e-commerce across city business sectors.
The detected security and site-management plugin sits inside the content-management layer, handling site hardening, maintenance controls and recovery workflows rather than the core commercial system. Buying usually sits with marketing, web operations, owner-managers or external agencies, with finance involved only where subscriptions, maintenance retainers or incident-response work accumulate. Adoption signals a business that relies on its public website for enquiries, bookings, transactions or regulated communications, but has not built a bespoke web stack. Field services and trades account for 18.1% of the cohort, construction 16.3%, wholesale and distribution 10.2%, healthcare providers 9.6%, and education and training 7.2%.

Within London, 166 actively trading companies are detected running this plugin on their public websites. The group is concentrated in practical, customer-facing web estates rather than large digital platforms, with many operators using CMS add-ons as part of ordinary sales, service and compliance workflows. The employment footprint is 1,776 reported roles across the cohort. That puts adoption on a specialist footing: visible enough for partner targeting and risk screening, but still centred on operating businesses with maintained sites rather than dormant web estates or experimental builds.
UK website operators using plugin-based security, analytics, forms or e-commerce sit inside ordinary privacy and electronic-communications obligations. ICO guidance requires users to be told when cookies or similar technologies are set, what they do and why they are used; consent must be actively and clearly given unless the cookie is strictly necessary for a user-requested online service. PECR applies even where cookie information is anonymous, while UK GDPR applies where personal data is processed. Security-related add-ons also complicate market classification: cyber-security activity does not map neatly to a single SIC code, so procurement teams tend to describe the activity rather than rely on registration labels.
Adoption appears likely to stay attached to familiar CMS estates rather than move into bespoke engineering teams. The user base looks weighted towards small operational websites, so change tends to arrive through agency retainers, bundled hosting and compliance checklists, not board-level software programmes. Privacy rules, security expectations and plugin-maintenance risk should keep renewal scrutiny high. Some users may consolidate around fewer add-ons as vendors bundle overlapping functions, while others will keep point solutions where existing templates, forms and checkout journeys are too costly to replace.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.
Adoption by company size
Adoption of iThemes rises with company size across the trading companies in this cohort. 0% of the 532,485 companies with under 10 employees run iThemes (123 detected). 0.3% of the 15,364 companies with 10–50 employees run iThemes (42 detected). 0.2% of the 1,763 companies with over 50 employees run iThemes (4 detected). That is a 0.2% gap between the over 50 employees and under 10 employees bands.

How iThemes 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.
