Companies Using Complianz in Cardiff: 77 Active Firms (2026)
Cardiff companies running website consent-management tools publish cookie notices and preference controls for visitors across the metropolitan area.
Adoption usually sits with website, marketing or operations teams rather than a standalone privacy office. For Complianz users, the tool’s job is practical: present cookie choices, hold consent preferences, and give internal teams a defensible way to run analytics, forms and advertising tags on maintained sites. The typical Cardiff adopter is small in operating terms, with median reported headcount of 6 employees and median turnover of £474k. That points to budgeted web governance, not an enterprise privacy programme: external agencies may configure the stack, but commercial teams still need the website to capture leads, bookings or enquiries without ignoring consent obligations.

Cardiff has 77 actively trading companies running Complianz, giving the city a compact but visible adoption base among organisations with maintained public websites. Employment is not negligible: these users report 1,660 employees between them, which puts the tool inside operational businesses rather than only hobby or brochure-only web presences. The sector mix leans towards practical local-commerce categories; field services and trades account for 29.9% of business classifications, while construction accounts for 23.4%. Those categories can overlap, but the pattern fits firms that need enquiries, job requests, bookings or quote forms while keeping cookie preferences visible to visitors.
Cookie consent sits at the junction of marketing measurement, website operations and privacy compliance. Procurement is therefore often folded into site maintenance, hosting or digital-agency retainers rather than run as a separate legal-technology purchase. Configuration matters more than the banner itself: non-essential scripts should be categorised, preference changes need to be easy to find, and consent logs have to match what the site actually loads. For Cardiff organisations selling, booking or collecting enquiries online, the practical risk is a mismatch between an acceptable notice and the tracking, form and embedded media behaviour underneath it.
Adoption appears tied less to privacy experimentation than to ordinary website upkeep. As sites are rebuilt, hosting contracts change and marketing teams review their measurement stack, consent tooling tends to be refreshed alongside search, forms and analytics work. Smaller users may keep the same plug-in if it remains easy to maintain; larger operators are more likely to ask for clearer audit trails, role ownership and agency handover notes. The local pattern suggests gradual replacement and reconfiguration rather than a rush into new consent platforms, especially where web governance sits across operations, marketing and external suppliers.

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.
