Field Services Companies Using One.com in the UK: 78 Active Firms (2026)
Field services using web hosting in the UK provide trade, installation, maintenance and repair services with simple hosted public websites.
For trades and service contractors, a hosted website platform usually sits at the light end of the digital stack: service pages, quote forms, proof of certification and local-search visibility rather than account-based selling. Adoption in this cohort points to owner-managed or operations-led teams that want a maintained public presence without a large in-house marketing function. The buying centre tends to be the proprietor, office manager or external web supplier, with the site acting as a trust and enquiry channel for local homeowners, property managers, facilities teams and small commercial clients.

78 actively trading UK field-services and trades firms in this cohort run the profiled hosted platform. Reported employment across the adopter group totals 786 people, consistent with small operational teams rather than enterprise estates. Within the wider field-services and trades hosting benchmark, the platform accounts for 1.6% of detected hosting across 4,913 sector websites, placing it ninth in the category ranking. Registered-address skew is fairly dispersed: the West Midlands, North West and East of England each account for 12.8%, while London and the South East each account for 9.0%.
Field-services adopters sit across several rulebooks rather than one sector licence. For building work in England, the Building Safety Regulator sets client, designer and contractor duties under the amended Building Regulations, with higher-risk projects bringing extra competence and accountability expectations. GOV.UK guidance also points installers towards competent person schemes where self-certification is permitted, while gas work requires statutory registration and regular renewal. For companies running a hosted website platform, the relevant digital layer is narrower: privacy notices, consent handling, enquiry-form security and care over certification claims, especially where domestic customers use the site to choose a contractor.
Hosted-site use in this trade cohort appears more defensive than expansionary: the website is a credibility layer, not the operating system of the business. Adoption tends to follow practical triggers such as a change of owner, a new service line, poor search visibility or pressure to show qualifications more clearly. Some firms may stay with low-maintenance hosted sites, while others move towards trade-specific booking, quoting and job-management tools. Bundling in the small-business software market may gradually reduce standalone hosting choices, but inertia is likely where the site already generates local enquiries.
Adoption by company size

How One.com 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.

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.
