Swindon's housing is a patchwork, and that shapes the work heating engineers get called out for. Old Town and the railway village around Mechanics Institute have Victorian terraces with older pipework, tight airing cupboards and combi boilers squeezed into awkward spots. Out at Wichelstowe, Haydon Wick and the Kingsdown estates, you're more likely dealing with modern builds, system boilers and unvented cylinders. Then there are the 1960s and 70s estates in places like Park North and Penhill, where original radiators and microbore pipework often mean a power flush before anything new goes in. Swindon sits on clay in parts, which is rough on buried external pipes and gas supplies, so ground movement can be a factor in leaks and repairs.

The businesses on this page are drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each business's homepage to confirm heating engineers work is what they primarily offer, which keeps unrelated businesses off the page. Permanently closed listings are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Our How We Verify page sets out the full list. For anyone without that badge, we haven't independently verified those things, so you'll want to run those checks yourself before booking.

Start with the basics. Ask for the engineer's Gas Safe ID card and check the register online with their licence number, making sure it covers the type of work you need, whether that's boilers, hobs or fires. Get at least two or three written quotes that name the boiler make and model, the warranty length, and whether flue, filter and controls are included. Ask about a Benchmark commissioning checklist, which should be completed and left with you after any new installation. Check what's covered if they need to return, and ask how they handle disruption to your hot water. Cheap quotes that skip the system flush or magnetic filter often cost more later.

Frequently Asked Questions

How much does a heating engineer cost in Swindon?
Call-out and labour rates usually sit between £50 and £90 an hour, with many firms charging a flat call-out fee of £60 to £100 that includes the first hour. A boiler service typically costs £70 to £120. A like-for-like combi boiler replacement generally runs £2,000 to £3,500 fitted, depending on the make, output and how much pipework needs altering. Moving a boiler or converting from a regular to a combi system pushes that higher. A power flush is often £350 to £600. Prices vary with the boiler brand, access, flue position and the condition of your existing system. Getting two or three quotes is normal and worth doing.
Do I need a Gas Safe registered engineer for boiler work?
Yes. It's illegal for anyone who isn't on the Gas Safe Register to work on gas boilers, fires or pipework. Ask to see their ID card, check the back for the types of gas work they're qualified to carry out, and confirm their details on the Gas Safe website. If you rent out a property, you also need an annual gas safety record from a registered engineer.
How often should I have my boiler serviced?
Once a year. Most manufacturers require an annual service to keep the warranty valid, and it's the best way to catch problems like a failing pump, a blocked condensate pipe or a leaking pressure relief valve before they leave you without heating in January. A service takes about 45 minutes to an hour and should include checking the flue, gas pressure and combustion.
When is it worth replacing my boiler rather than repairing it?
As a rough guide, if the boiler is over 12 to 15 years old, needs frequent repairs, or the quote for a major part like a heat exchanger or PCB is over about £400 to £500, replacement usually makes better sense. Older non-condensing boilers run at around 70 to 80 percent efficiency, while modern condensing models reach 90 percent or more, so you'll also see savings on your gas bills. Ask the engineer for a straight comparison of repair versus replacement costs.
Should I consider a heat pump instead of a new gas boiler?
It depends on your home. Heat pumps work best in well-insulated properties with larger radiators or underfloor heating, which suits many newer Swindon builds better than draughty Victorian terraces. Installation typically costs £7,000 to £13,000 before any available grant, and the Boiler Upgrade Scheme can currently reduce that. Ask any installer for a heat loss calculation for your property before committing, and check they hold relevant trade accreditation for heat pump work.
How do I choose between heating engineers and check they're reliable?
Check their Gas Safe registration yourself on the official register, using their licence number. Ask for proof of public liability insurance and read recent online reviews, looking at how they respond to complaints as well as the star rating. Get quotes in writing that name the exact boiler and list what's included, and ask what warranty comes with both the boiler and their workmanship. Be wary of anyone who pushes for a deposit upfront, won't put the price in writing, or can't give you a company name or landline. A Trust Verified badge on this page means we've checked these things, but for any business without one, those checks are down to you.
