Construction Companies Using One.com in the UK: 68 Active Firms (2026)
Construction firms using managed web hosting in the UK deliver building, contracting and specialist trade services through public websites.
Website ownership in this niche usually sits with owner-managers, commercial directors or a small admin-and-marketing function, not a digital product team. The hosting layer does a plain job: keep a brochure site live, handle enquiry forms, show project evidence, publish service areas and make accreditation cues visible before a tender or site visit. Adoption therefore signals a contractor with some direct-channel discipline and enough budget for managed upkeep, but not necessarily a complex web stack. Buyers reached through these sites are typically property owners, developers, facilities managers, principal contractors and local householders comparing credible suppliers.

Across the UK, 68 companies in this construction cohort run the managed-hosting stack, so adoption is visible but niche. Reported headcount totals 568, pointing to a small-employer bias rather than a workforce-heavy sample. In the sector's detected-hosting ranking, the system sits ninth at 1.5%. Regional spread is fairly even at the top: South East, London and East of England each account for 13.2%, followed by North West at 11.8% and Yorkshire and The Humber at 10.3%.
UK construction has multiple rulebooks rather than a single sector licence. HSE's Construction (Design and Management) Regulations 2015 set duties around planning, role competence, coordination and worker consultation, while HMRC's Construction Industry Scheme shapes how contractors handle subcontractor payments. OPSS is the UK regulator for construction products and works with the Building Safety Regulator inside HSE on building-safety-related issues. For companies running a simple hosted site, the public-facing compliance task is usually evidential: accreditations, project histories, safety credentials and clear enquiry routes have to support procurement scrutiny.
Adoption appears likely to remain practical rather than fashion-led. Contractors in this bracket tend to value low-maintenance web operations, visible proof of prior work and enquiry capture over elaborate digital customer journeys. Migration pressure may come from agency relationships, bundled site-management packages and the need to keep privacy, security and contact workflows tidy. The cohort does not look like a developer-led software market; it looks like a set of construction businesses using hosted web infrastructure as a modest sales-support and trust-building layer.
Adoption by company size
Adoption of One.com rises with company size across the trading UK construction companies in this cohort. 0% of the 231,908 companies with under 10 employees run One.com (55 detected). 0.1% of the 8,701 companies with 10–50 employees run One.com (11 detected). 0.3% of the 662 companies with over 50 employees run One.com (2 detected). That is a 0.3% gap between the over 50 employees and under 10 employees bands.

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. construction 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 construction 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.
