Rankings on this page are driven by public review rating and review count, sourced from third-party business listings, with a small lift applied to businesses that have a working website and a contactable phone number. We check each business's homepage to confirm that heating engineering is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our full verification covering qualifications, insurance, trading history, customer review history, and registered company information. See our How We Verify page for the full list. Other businesses on this page have not been independently verified by us, and inclusion here is not an endorsement.
