B2B Using Google Tag Manager in the UK: 24,246 Active Firms (2026)
UK B2B firms running web tag-management tools sell to other organisations and use website instrumentation for marketing, analytics and consent signals.
For business-to-business suppliers, Google Tag Manager usually sits between the public website, analytics stack, paid-media reporting and consent controls. Marketing operations, revenue operations, web teams and compliance owners tend to be the internal buying centres, because the system governs what fires on key journeys and who can change it. Adoption usually signals a marketing budget large enough to justify controlled measurement, plus an in-house or retained technical resource to maintain tags without routing every campaign change through engineering. The underlying customer engagements are typically considered-purchase contracts, distributor relationships or retained services rather than high-volume consumer checkout.

Across the UK, 24,246 actively trading business-to-business firms run the profiled tag-management system. Reported employment across this cohort totals 30,698 people. Among detected tag-management use for this sector, the system ranks first at 99.7%, compared with 0.7% for the next detected tag-management category, so the category is concentrated rather than split across several competing stacks. Registered-office concentration is weighted towards London, which represents 21.8% of the cohort, followed by the South East at 15.0%, the North West at 11.4%, the East of England at 9.7% and the West Midlands at 8.6%.
UK business-to-business activity is not a single licensed market; the rulebook depends on the underlying service, such as finance, telecoms, data processing or professional services. Website tagging adds a data-processing layer to that picture. The ICO’s PECR guidance says the electronic-mail consent rule does not apply to “corporate subscribers”, but senders still need to identify themselves and provide a valid opt-out address. UK GDPR remains relevant where business-contact or website-behaviour data identifies a person. Live marketing calls need CTPS and TPS screening, and organisations must not call businesses that have objected.
Adoption appears mature, but management quality is likely to vary. Companies with established marketing operations tend to use tag governance as part of consent management, attribution and campaign evidence; leaner teams may still carry older scripts, duplicate triggers and unclear ownership. Browser privacy changes and tighter customer scrutiny should keep pressure on the tag layer, especially where sales teams rely on outbound nurture and conversion reporting. Consolidation is more likely to show up through bundled analytics, consent and customer-data tooling than through a wholesale move away from tag management itself.

Key facts
About 10% of the trading cohort reports turnover above £5M (2,437 of 24,246 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (1,506 firms), so a sizeable share is in its first few filing cycles.
Among B2B firms with a detectable tag-management system, this tag manager accounts for 99.7% (24,246 of 24,309); the nearest detected alternative accounts for 0.7% (181).
A co-running content-management tool appears on 64.9% (15,727) of these sites, while analytics, site-infrastructure and form anti-abuse tools appear on 45.4% (11,006), 43.8% (10,616) and 41.7% (10,104), respectively.
London accounts for 21.8% (5,283) of the cohort, followed by the South East at 15.0% (3,635) and the North West at 11.4% (2,760).
The largest overlapping sector tags are Advanced Manufacturing at 14.4% (3,487), Wholesale & Distribution at 13.5% (3,283), Field Services & Trades at 12.2% (2,953) and Construction at 12.1% (2,927).
For B2B marketing, the ICO says PECR covers direct marketing by live or automated calls, electronic mail and fax; UK GDPR still applies where personal data is processed.

How Google Tag Manager 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.
Google Tag Manager is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
