10 Best Gas Engineers in Telford for 2026

Telford's housing stock is genuinely varied, which matters when you're calling out a gas engineer. The new-build estates around Hadley, Donnington, and Lawley tend to have combination boilers installed within the last decade or so, often Worcester Bosch or Vaillant units that need a qualified engineer familiar with modern condensing technology. Older properties in areas like Wellington, Madeley, and parts of Dawley are more likely to have conventional systems with separate hot water cylinders, ageing pipework, and sometimes a mix of copper and plastic runs that need careful assessment. Prices reflect that range too. A straightforward boiler service on a combi in a newer home typically runs £60 to £90, while a full boiler swap including flue, controls, and system flush on an older semi can easily come to £2,000 or more depending on the complexity.

Every business on this page was drawn from third-party public business listings and ranked by review rating alongside review count, so highly rated engineers with a solid volume of feedback rise naturally to the top. We also apply a small lift to businesses that have a working website and a listed phone number, since those signals suggest an active operation. Before any listing appears here, we check the business's own website to confirm that gas engineering work is genuinely what they primarily offer, which is how unrelated trades get filtered out. Any listing that's been flagged as permanently closed is removed automatically. Where you see a Trust Verified badge next to a business name, that engineer has gone through our full verification process covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see exactly what that involves on our How We Verify page. Businesses without that badge have not been independently verified by us, and you should carry out those checks yourself before booking.

When you do contact an engineer, ask specifically whether they're on the Gas Safe Register and request their Gas Safe ID card number so you can check it directly on the official register website. For any installation work, you should receive a Building Regulations compliance certificate. On a boiler replacement, ask the engineer to confirm whether the existing flue route and condensate drain location are suitable, and get at least two or three quotes before committing. If the property has a shared gas supply or you're unsure where the stopcock is, flag that before work begins. A written quote that breaks down labour, parts, and any disposal costs saves arguments later.
