9 Best Gas Engineers in Cheltenham for 2026

Cheltenham's housing stock is a real mix. You've got grand Regency terraces around Montpellier and Pittville with their tall ceilings and original pipework that can test any engineer's patience, Victorian semis across Leckhampton and St Paul's, and a steady spread of 1960s to 1990s estates out towards Bishops Cleeve and Benhall. Older properties often run ageing conventional boilers with open-flued systems, while newer builds tend to have combi setups that need a different approach entirely. Add in Cheltenham's frequent cold snaps off the Cotswold escarpment and it's no surprise that local engineers stay busy through autumn and winter. Whether your priority is a full boiler replacement, an annual service to keep your warranty valid, or tracing a gas leak before it becomes something worse, getting the right engineer matters.

The businesses on this page were drawn from third-party public business listings and ranked by review rating and review count, with a small lift applied to businesses that show a working website and phone number. We check each business's homepage to confirm that gas engineering work is what they primarily do, which is how unrelated trades get kept off the page. Any listing flagged as permanently closed is removed automatically. Where you see a Trust Verified badge next to a business, that company has additionally passed our full verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see the full list of what that covers on our How We Verify page. For any business without that badge, those checks haven't been carried out by us, and it's worth doing them yourself before you book.

Before you commit to anyone, confirm they're on the Gas Safe Register. That's the legal requirement in the UK for anyone working on gas appliances, and you can check a registration number on the Gas Safe website in seconds. Ask for a written quote before work starts, not just a verbal estimate, and make sure it specifies the scope of the job, parts included, and what happens if additional work is needed once they're in. For boiler installations, your engineer should issue a Building Regulations completion certificate (a CORGI or Gas Safe certificate of commissioning). Getting two or three quotes for larger jobs like a full boiler swap is completely normal and often reveals a price difference of £200 to £400 on the same specification. Don't skip the paperwork just because someone seems friendly or busy.
