HVAC Companies Using Microsoft Clarity in the UK: 56 Active Firms (2026)
HVAC companies running web behaviour analytics sell, install or maintain heating, ventilation and refrigeration systems across the UK.
For HVAC and refrigeration operators, this analytics layer usually sits in the marketing and sales stack rather than in engineering. It helps teams see where prospective buyers abandon quote forms, service booking flows or project-enquiry pages, and it tends to be adopted once a contractor has enough inbound traffic to care about conversion friction. The buyer is often a commercial director, marketing manager or external web agency serving an established installer-maintainer, with use cases spanning planned maintenance contracts, specification-led installation work and reactive service leads.

UK adoption remains concentrated: 56 actively trading HVAC and refrigeration firms are detected running this behaviour analytics tool. Reported employment totals 1,396 across the cohort, with 53 of 53 firms reporting headcount (100%). Within detected analytics implementations across the sector, the tool ranks fourth at 4.4% on a sector denominator of 1,274. The regional skew is southern and metropolitan: South East and London each account for 23.2% of the cohort, followed by East of England and West Midlands at 12.5% each, and Yorkshire and The Humber at 7.1%.
Website behaviour analytics creates a procurement question before it creates a software question. HVAC firms using session replay or heatmap-style tools need clear consent wording, privacy-notice coverage and supplier terms that deal with customer identifiers, quote forms and service-location details. The operational risk is lower than for core field-service systems, but the tool still touches lead capture and may sit alongside call tracking, forms and live chat. For multi-branch installers, control of tags and pixels can also become a governance issue when local campaigns are run by different agencies.
Adoption appears likely to remain tied to website rebuilds, agency retainers and pressure to improve quote conversion rather than to standalone analytics programmes. HVAC remains a fragmented contractor market, so many operators will treat behaviour tracking as part of a broader digital housekeeping bundle with search, forms, consent and tag management. Larger installers and maintenance groups tend to have clearer use cases because lost enquiries have a visible operational cost. Smaller firms may keep relying on basic traffic reporting unless margins or lead costs force closer inspection of the customer journey.
Adoption by company size
Adoption of Microsoft Clarity rises with company size across the trading UK HVAC companies in this cohort. 0.1% of the 23,256 companies with under 10 employees run Microsoft Clarity (30 detected). 1.7% of the 1,144 companies with 10–50 employees run Microsoft Clarity (19 detected). 7.2% of the 83 companies with over 50 employees run Microsoft Clarity (6 detected). That is a 7.1% gap between the over 50 employees and under 10 employees bands.

How Microsoft Clarity 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. HVAC 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 HVAC 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.
