Bath's housing stock throws up more heating quirks than most cities its size. You've got Georgian terraces around Larkhall and Widcombe with original chimney breasts and no cavity walls, Victorian conversions in Oldfield Park where flats share a single stack, and newer estates out towards Odd Down or Weston with combi boilers barely a decade old. A heating engineer working here needs to know how to fit a system boiler into a listed building without upsetting conservation rules, just as much as they need to handle a straightforward combi swap in a modern semi. The hilly terrain and older pipework in parts of the city also mean low water pressure and airlocks come up more often than in flatter, newer towns, so local experience genuinely counts for something.

The businesses featured here were pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a modest boost for those showing a working website and phone number. We then checked each firm's homepage to confirm heating engineering is actually their main line of work, which stops general handymen or unrelated tradespeople slipping onto the page. Listings flagged as permanently closed are stripped out automatically as part of that process. Where you spot a Trust Verified badge, that business has gone through our fuller 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 exactly what's involved). Businesses without that badge haven't been through that process with us, so it's worth doing your own homework before booking anyone.

Before you commit to a heating engineer, ask to see their Gas Safe registration card and check the licence number against the register yourself, it takes two minutes online. Get written quotes from at least two or three firms, ideally based on them actually looking at your boiler or system rather than a phone estimate, since access issues (that tricky airing cupboard, a boiler crammed into a loft) can change the price. Ask what's included: a benchmark certificate, a warranty on parts and labour, and whether they'll register a new boiler with the manufacturer for you. For bigger jobs like a full system replacement, get a breakdown of pipework, radiators and any power flushing costs separately, so you're not comparing one vague number against another.
How We Select & Rate The Best Heating Engineers in Bath

Ranking is driven primarily by review rating and review count from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm heating engineering work is what they primarily do, which keeps unrelated trades off this page. Listings flagged as permanently closed 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 complete list. Other businesses here haven't been independently verified by us, and appearing on the page isn't an endorsement. Always do your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a heating engineer cost in Bath?
A straightforward annual boiler service typically runs £70 to £110. Diagnosing and fixing a fault, like a faulty diverter valve or PCB, tends to land between £120 and £350 depending on parts. A full combi boiler swap in a similar-sized property usually costs £1,800 to £3,200 including labour, while a bigger system upgrade with new radiators or a cylinder can push past £4,500. Older properties in areas like Bathwick or Lansdown with tricky pipe runs sometimes cost more due to access. Getting two or three quotes is normal practice here and worth doing even for smaller jobs, since prices vary more than people expect.
How long does a boiler installation take in Bath?
A like-for-like combi boiler replacement usually takes a single day, sometimes finishing by early afternoon if access is easy. Moving the boiler to a new location, converting from a system boiler to a combi, or dealing with older lead or steel pipework common in Georgian and Victorian properties around the city centre can stretch the job to two or three days. Always ask your engineer to confirm the expected timescale before work starts, and check whether they'll need to isolate the water at the stopcock for part of that time.
Do I need a Gas Safe registered engineer for boiler work in Bath?
Yes, by law anyone working on gas boilers, gas fires or gas pipework must be Gas Safe registered, and this applies whether it's a repair, service or full installation. Ask to see their Gas Safe ID card on the day and check the licence number on the Gas Safe Register website beforehand. It's also worth checking the card lists the specific type of work being done, such as boilers or gas fires, since registration is broken down by category.
What's the difference between a boiler service and a boiler repair?
A service is routine maintenance, usually annual, where the engineer checks the burner, flue, pressure and safety devices, cleans components where needed, and issues a report confirming the boiler's condition. A repair is reactive work to fix a specific fault, like no hot water, banging noises, or an error code on the display. Some Bath firms offer combined service-and-repair visits at a discounted rate if you book both together, so it's worth asking when you get a quote.
How often should I get my boiler serviced?
Once a year is standard, and most manufacturers require it to keep the warranty valid. It's also a good idea to time it for late summer or early autumn, before the colder months hit and engineers get booked up. If your boiler is over ten years old or you've noticed odd smells, uneven heating, or the pilot light going out repeatedly, get it checked sooner rather than waiting for the annual date.
How do I choose between different heating engineers in Bath?
Start by checking each engineer's Gas Safe registration number yourself on the official register, don't just take the card at face value. Read through recent reviews rather than just the star rating, looking for comments about punctuality, tidiness and whether the final price matched the quote. Ask for proof of public liability insurance and, for bigger jobs, ask if they can show you examples of similar work they've completed nearby. Finally, get quotes in writing from a few different firms so you can compare what's actually included, not just the headline figure.
