field services Using Site Kit in the UK: 1,243 Active Firms (2026)
Field services firms running website tooling deliver installation, maintenance and repair work for UK property, infrastructure and trade customers.
For field-services operators, this measurement plug-in sits where local search demand, quote capture and service-area content meet. Budget usually sits with marketing, a web agency or a commercially minded operations team rather than central IT. Its presence tends to signal a contractor with a maintained public website, paid or organic acquisition activity, and a need to reconcile enquiries, bookings and call-backs across local pages. The relevant buyers are usually mid-market trade contractors, compliance-led installers and multi-area maintenance providers, not software vendors.

The UK adoption cohort contains 1,243 actively trading field-services and trade firms running this website measurement stack. Reported employment totals 4,329, and 122 of 122 headcount disclosures show employees. Within field-services analytics tools, the system ranks second: its share is 10.1% against a sector denominator of 12,249, while the main web-analytics package reaches 91.3%. The regional tilt is not especially London-centred. The South East accounts for 14.8% of adopters, followed by South West at 13.0%, North West at 12.2%, East of England at 11.0% and London at 9.0%.
Field services procurement is fragmented because the underlying trades sit across building control, competence schemes and safety registration rather than a single sector licence. In England, Building Safety Regulator duties shape contractor, designer and client responsibilities on regulated building work, while competent-person schemes let qualified installers self-certify certain work instead of seeking building regulations approval each time. Gas work is narrower: businesses and engineers need statutory registration before carrying it out legally. Website measurement therefore has a compliance edge as well as a marketing role; enquiry forms, booking journeys and call-back requests create personal-data handling under GDPR and ICO expectations, while competence claims on local service pages need governance.
Adoption appears tied less to experimental analytics work than to routine pressure on acquisition costs and local visibility. Field-services operators tend to inherit a web stack from agencies, then keep the parts that make phone calls, quote forms and service-area pages easier to attribute. Bundling may pull more of this functionality into general website management, while privacy expectations push firms towards clearer consent, cleaner tagging and less casual form tracking. The cohort also looks exposed to consolidation among web agencies and trade platforms; where that happens, smaller contractors may follow template choices rather than selecting analytics tools independently.

Key facts
About 4% of the trading cohort reports turnover above £5M (56 of 1,243 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (77 firms), so a sizeable share is in its first few filing cycles.
Within field services and trades, the profiled analytics system accounts for 10.1% (1,243) of 12,249 companies with a detectable analytics system, behind the largest detected system at 91.3% (11,181).
Co-occurrence is concentrated rather than fragmented: 99.9% (1,242) also run the most common co-detected technology, while 83.7% (1,040) also run the largest detected analytics system.
Registered offices skew outside London: South East accounts for 14.8% (184), South West 13.0% (161), North West 12.2% (152), East of England 11.0% (137) and London 9.0% (112).
Building work in England falls under Building Safety Regulator guidance introduced in 2023, including client, designer and contractor duties under the Building Regulations etc. (Amendment) (England) Regulations 2023.
Gas work has a narrower authorisation route: businesses and engineers need annual registration before carrying it out legally.

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. field 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 field 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.
Site Kit is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
