Companies Using OSAM Websites in the UK: 339 Active Firms (2026)
Companies using website tech run public sites on a specialist website platform, in the UK digital advertising and services market.
For most OSAM Websites users, the platform sits inside the sales and service workflow rather than a pure brand channel. Adoption usually signals a firm with enough marketing need to maintain content, enquiry forms, location pages and sometimes transactional journeys, but not usually an in-house engineering function. Buying responsibility tends to sit with owners, office managers, marketing generalists or an external web agency. Engagements are therefore practical: keeping pages editable, capturing leads, handling consent notices, and making service information visible to customers in markets where search and paid media matter.

The UK adoption picture is narrow and service-heavy: 339 companies run OSAM Websites on public sites, with reported employment of 1,408 people across firms that publish headcount. Usage skews towards practical local-commerce categories rather than enterprise software buyers: field services and trades represent 53.1% of the cohort, with construction at 28.9% and smaller overlaps in manufacturing, distribution and healthcare-provider activity. The median user reports 6 employees and around £462,000 turnover, which points to owner-managed and small departmental website estates rather than large digital-platform programmes.
Platform adoption does not bring a sector-specific operating licence, but the content and tracking choices around these sites sit within cross-cutting rules. Advertising content is assessed through the ASA and the advertising codes, while the ICO oversees GDPR and PECR duties around cookies, consent, direct marketing and personal data. Where sites solicit enquiries or transactions, the CMA and local trading standards can become relevant through consumer-law rules on misleading, unfair or aggressive marketing. Digital advertising and direct-marketing trade bodies provide norms, but they do not remove the need for firms to evidence lawful consent and claims substantiation.
Adoption appears tied to the economics of local lead generation rather than enterprise technology renewal. The cohort tilts towards services businesses that need brochure content, forms, search visibility and basic compliance controls, so switching tends to happen when agencies refresh sites, consent tooling changes or owners want a simpler editing workflow. Scale-up scarcity may keep the user base fragmented: many firms appear to need managed support rather than in-house web teams. Over time, bundling across hosting, security, consent and analytics may matter more than particular page-design features, especially as privacy expectations reduce tolerance for untidy tracking practices.

Key facts
5% of the cohort was incorporated since 2022 (20 firms), so a sizeable share is in its first few filing cycles.
100.0% of sites in the cohort also show a content-management marker, while 81.1% show bot-protection and page-builder markers.
Field Services & Trades accounts for 53.1% of the cohort and Construction for 28.9%; sector tags overlap, so these shares are not a closed distribution.
Website-build and digital-marketing work is generally outside a sector-specific operating licence, but advertising, data-protection and consumer-law regimes can still apply.
The UK digital ad market reached £40.5 billion in 2025, up 10% year on year, with video investment up 20% to £9.3 billion.
The UK digital sector accounted for 6.8% of total GVA in 2024 at £177.2 billion in current prices.

How OSAM Websites 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.
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.
