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 phone number. Before inclusion, we check each business's homepage to confirm gas engineering is what it primarily offers, which keeps unrelated trades off the page. Permanently-closed listings are removed automatically. Businesses marked Trust Verified have additionally passed our full verification, covering trade qualifications and accreditations, public liability 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 is not an endorsement. Always do your own checks before hiring.
