IT Services Companies Using Site Kit in the UK: 329 Active Firms (2026)
IT services firms using web tags deliver managed technology, cloud support and digital operations with public websites instrumented for measurement in the UK.
For managed services and IT support providers, this site-measurement add-on sits in the marketing-operations layer rather than the delivery stack. It connects website publishing, search visibility, traffic measurement and form conversion monitoring, which matters for firms selling retained support, cloud migration, security assurance and project-based systems work to business buyers. Adoption usually signals a commercially maintained website, some internal or agency marketing capacity, and a direct-channel sales motion where enquiries, content performance and service-line pages are actively reviewed.

Across the UK, 329 actively trading IT services and managed services firms are running this site-measurement add-on. They report 2,200 employees across 117 firms, and every one of those firms reports some headcount. Among 2,931 sector firms in the analytics category, the system ranks second with an 11.2% share. The regional profile is tilted towards London (19.5%) and the South East (19.1%), followed by the West Midlands (10.9%), North West (10.6%) and South West (9.1%).
Website analytics in managed services sits close to procurement and trust conversations. A prospect reviewing an outsourced IT partner may ask how contact forms, tracking tags and marketing cookies interact with GDPR, PECR and ICO guidance, particularly where cyber, infrastructure or cloud support pages invite disclosure of operational problems. The stack also points to a lighter vendor-ecosystem model: many firms appear to rely on mainstream publishing, consent and analytics components rather than bespoke measurement infrastructure, so governance often depends on configuration discipline, agency oversight and clear ownership between marketing and technical teams.
Adoption appears tied less to service-delivery capability than to the maturity of a provider's route to market. Firms with retained support contracts and cross-sellable cloud or security services tend to need clearer evidence of which service pages generate enquiries, while very small consultancies can tolerate simpler reporting. The next phase is likely to be shaped by privacy governance, tag consolidation and analytics bundled into publishing or customer-management tools. That favours teams able to document consent, attribution and ownership without adding much operational overhead.
Adoption by company size
Adoption of Site Kit rises with company size across the trading UK IT services companies in this cohort. 0.2% of the 119,548 companies with under 10 employees run Site Kit (206 detected). 5.4% of the 2,157 companies with 10–50 employees run Site Kit (117 detected). 4.4% of the 181 companies with over 50 employees run Site Kit (8 detected). That is a 4.2% gap between the over 50 employees and under 10 employees bands.

How Site Kit 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. IT services companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of IT services companies with a detectable system — not of all UK companies.
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.
