Construction Companies Using TrustedSite in the UK: 119 Active Firms (2026)
Construction businesses using website trust tools signal online credibility for contractor, trade and project enquiries in the UK.
For construction adopters, third-party site assurance sits near the start of the enquiry funnel: it gives contractors, subcontractors and specialist trades a visible trust layer around contact forms, quotation requests and project references. The buying centre is usually commercial or owner-managed rather than a dedicated software team, with the tool treated as part of the public website stack. Running it tends to signal a direct-channel posture, enough tender or project-enquiry volume to care about pre-sale reassurance, and a need to look credible to customers, main contractors and suppliers before an offline conversation starts.

Within UK construction, 119 companies running this trust-badge technology are actively trading, and their reported headcount totals 958. The system accounts for 76.8% of detected trust-badge use across the construction cohort, ahead of another trust-badge tool at 23.2%. Regional concentration is modest but visible: South East accounts for 16.8%, London 12.6%, North West 10.1%, South West 9.2% and Scotland 8.4%. That spread looks more like dispersed contractor adoption than a software-cluster pattern, which fits a category sold through website build, hosting and credibility workflows.
UK construction is governed through several regimes, not a dedicated sector licence. HSE’s Construction (Design and Management) Regulations require construction roles to plan work so risks are managed, appoint suitable people, coordinate activity and consult workers. HMRC’s Construction Industry Scheme affects contractor-subcontractor payments, with registration changing deduction treatment. OPSS leads construction-products regulation and works with the Building Safety Regulator within HSE on building-safety matters. For website assurance, procurement due diligence therefore tends to sit around identity, claims substantiation, accessibility and privacy, rather than formal authorisation to trade.
Adoption appears tied to how construction firms win work outside repeat referral networks. The cohort looks weighted towards small operating teams; many will keep badge and website-stack choices bundled with low-cost hosting, site-build or agency-managed packages. Where tenders and project enquiries move through digital channels, assurance layers may remain useful, but churn is plausible if badges are absorbed into wider website, analytics or security bundles. Vendor consolidation would probably make the tool less visible as a standalone choice, especially among trades where the website is maintained by a generalist supplier.
Adoption by company size
Adoption of TrustedSite rises with company size across the trading UK construction companies in this cohort. 0% of the 231,908 companies with under 10 employees run TrustedSite (97 detected). 0.2% of the 8,701 companies with 10–50 employees run TrustedSite (20 detected). 0.2% of the 662 companies with over 50 employees run TrustedSite (1 detected). That is a 0.2% gap between the over 50 employees and under 10 employees bands.

Key facts
About 1% of the trading cohort reports turnover above £5M (1 of 119 firms) — the rest sits below that revenue band.
8% of the cohort was incorporated since 2022 (10 firms), so a sizeable share is in its first few filing cycles.
Within construction, the profiled trust-badge tool accounts for 76.8% (119) of the 155 companies with a detectable trust-badge system; the other detected system accounts for 23.2% (36).
Among construction businesses running the profiled trust-badge tool, 95.8% (114) also run a website-builder platform and 68.1% (81) also run a domain-related web platform.
Analytics and content-management tags are less common in this cohort: 19.3% (23) also run analytics tooling, while 13.4% (16) run a content-management system.
Registered-office concentration is modest: South East accounts for 16.8% (20), followed by London at 12.6% (15) and North West at 10.1% (12).
UK construction does not have a single sector licence; duties sit across HSE’s Construction (Design and Management) Regulations 2015, HMRC’s Construction Industry Scheme and construction-products oversight by the Office for Product Safety and Standards.

How TrustedSite 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.
