Companies Using CookieYes in London: 2,753 Active Firms (2026)
Companies running consent-management tools on public websites manage cookie notices and visitor privacy choices across London.
Adoption usually sits with marketing operations, web teams and legal or privacy owners rather than a single IT buyer. The tool sits between analytics tags, forms and site content, holding visitor preference records before non-essential scripts are allowed to run. Running it tends to signal an organisation with active inbound demand, public content, and some internal ownership of GDPR-aligned web governance. Buyers are commonly mid-market or enterprise teams in services, finance, property, media and technology, although leaner operators can adopt when website traffic, lead capture or advertising measurement makes consent administration hard to leave to a static banner.

London has 2,753 actively trading companies running this consent-management tool on public websites. Reported employee counts sum to 7,751 within this adoption set, pointing to a broad long tail of small operators as well as mid-market firms with dedicated web, marketing or compliance roles. Turnover scale is uneven: 201 adopters report more than £5M, while 216 have been incorporated since 2022. The adoption picture therefore looks less like a single software vertical and more like a cross-sector compliance layer for firms that sell, market or capture enquiries online.
GDPR gives the operating frame: consent wording, preference storage and tag behaviour all need to be configured before marketing teams can treat website analytics as usable. Sector mix is dispersed, with Construction at 9.8%, Real Estate & Property at 8.6%, Field Services & Trades at 8.3%, Healthcare Provider at 8.1% and SaaS at 6.7%. That spread matters for procurement. Some adopters buy through agency-managed website projects, while others route the decision through legal, marketing operations or information-security review, especially where forms, advertising pixels and customer portals sit on the same site.
Adoption appears likely to remain tied to website redevelopment, analytics governance and procurement hygiene rather than a standalone technology cycle. Smaller users may keep consent management bundled with their web agency or content platform, while larger operators tend to pull it into formal privacy and marketing-operations workflows. Consolidation pressure is more likely to come from adjacent web, analytics and compliance tooling than from demand for banners alone. The cohort therefore looks set to evolve through stack clean-up, audit requirements and channel measurement needs, rather than through a separate buying wave.

How CookieYes 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.
