B2B Companies Using Adverticum in the UK: 160 Active Firms (2026)
B2B firms running web advertising infrastructure use on-site ad delivery and campaign measurement tools in the UK market.
Marketing, partnerships and revenue teams tend to be the buying centres for this stack, rather than engineering-led platform groups. In B2B settings it usually sits on public-facing property, advisory or service-market websites, helping teams schedule ad placements, measure campaign response and manage sponsor or partner inventory. Adoption signals that the firm has moved beyond a brochure site: there is enough audience volume, commercial intent or paid acquisition activity to justify ad operations, tagging and privacy controls. Typical users appear to be lean organisations with direct digital channels, where marketing operations, sales development and web administration often overlap.

The UK adoption picture is small: 160 actively trading B2B firms run this ad-serving stack, with 780 reported employees between them. Within the detected advertising ranking for this sector, the system sits fifth at 1.9%. Registered-office skew points to London at 31.9%, followed by the East of England at 15.0%, the South East at 11.3%, the North West at 9.4% and the South West at 6.3%. That pattern looks more like a specialist deployment base than a default marketing layer across the whole B2B market.
B2B marketing is not covered by a single UK licence; obligations follow the underlying activity and the way contact data is used. The ICO treats PECR as relevant to direct marketing by live or automated calls, electronic mail and fax. Its electronic-mail rule does not apply to corporate subscribers, so email and text campaigns to corporate bodies do not need PECR consent, but senders still need to identify themselves and provide an opt-out route. UK GDPR applies where business-contact or campaign-interaction data relates to identifiable people. Live calling also brings screening duties against CTPS and TPS, plus suppression of organisations that have objected.
Adoption appears likely to stay selective rather than universal. The cohort has a property-market skew and a long tail of small commercial teams, so continued use tends to depend on whether a website carries monetisable inventory or runs partner-funded campaign activity. Stack rationalisation may pull some users towards bundled analytics and tag-management environments, while privacy work pushes others to keep tighter control of consent, suppression and campaign logging. For many business-to-business suppliers, the deciding factor is less technical novelty than whether the channel still produces attributable enquiries without adding avoidable compliance work.
Adoption by company size
Adoption of Adverticum varies by company size across the trading UK B2B companies in this cohort. 0.2% of the 76,784 companies with under 10 employees run Adverticum (133 detected). 0.1% of the 31,788 companies with 10–50 employees run Adverticum (26 detected). 0% of the 3,773 companies with over 50 employees run Adverticum (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 (2 of 160 firms) — the rest sits below that revenue band.
31% of the cohort was incorporated since 2022 (51 firms), so a sizeable share is in its first few filing cycles.
Within B2B firms with a detectable advertising system, the page’s system ranks fifth by observed share at 1.9% (160), against a category denominator of 8,620 companies.
All 160 companies in the cohort also show analytics, tag-management and publisher-ad inventory tools at 100.0% (160) for each category.
Security, CDN, content-management and contact-form infrastructure is almost universal, each appearing at 99.4% (159) of the cohort.
London accounts for 31.9% (51) of the cohort by registered ITL1 region, ahead of the East of England at 15.0% (24) and the South East at 11.3% (18).
The ICO’s PECR guidance treats B2B emails or texts to corporate subscribers differently from consumer marketing: consent is not required, but sender identity and opt-out details still are.

How Adverticum 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. B2B 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 B2B 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.
Adverticum is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
