Nuneaton's housing stretches from Victorian terraces around Chilvers Coton to newer estates out towards Bermuda Park and Camp Hill, and that mix throws up all sorts of heating work. Older properties often still have back boilers or ageing combis tucked into kitchen cupboards that need replacing, while the newer builds around Whitestone and Weddington tend to need servicing, power flushing or the odd radiator that's never balanced properly. A fair few streets in the town centre and around Attleborough still run on older pipework too, so an engineer who knows the area's housing stock is worth having, particularly if you're dealing with a combi conversion or trying to squeeze a system boiler into a smaller loft space.
The businesses listed here come from public business listings, and we've ranked them using their review rating and how many reviews they've collected, with a small boost for firms that have a working website and phone number listed. We also check each business's homepage ourselves to confirm heating engineering is genuinely their main line of work, which stops general builders or unrelated tradespeople sneaking onto a list like this. Any listing that's shown as permanently closed gets removed as part of that process. Where you spot a Trust Verified badge next to a business, that firm has gone further and 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 exactly what that involves. For businesses without the badge, none of that has been independently checked by us, so it's worth doing that legwork yourself before agreeing to any work.
Before you book anyone, ask to see their Gas Safe registration card and check the licence number against the register yourself, it takes two minutes and protects you if anything goes wrong. Ask what's included in a quote, whether that's a full boiler swap, a service, or a repair, because prices can jump once an engineer finds a corroded heat exchanger or a system that needs a full flush. Get at least two or three quotes for anything beyond a basic service, particularly for boiler replacements, since prices in the Nuneaton area can vary by a few hundred pounds between firms for what looks like the same job. Finally, ask about the warranty on parts and labour, and get it in writing before anyone starts.
How We Select & Rate The Best Heating Engineers in Nuneaton
Rankings are based on review rating and review count pulled from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm heating engineering work is what they primarily offer, 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 shown here have not been independently verified by us, and their inclusion isn't an endorsement. Always carry out your own checks before hiring.

How much does a heating engineer cost in Nuneaton?
A standard boiler service typically runs from around £60 to £100, while a boiler repair can range from £80 to £300 or more depending on the fault, whether it's a faulty diverter valve, a broken pump, or a PCB that needs replacing. A full boiler replacement, say swapping an old back boiler for a new combi, usually falls between £1,800 and £3,500 including labour and parts, though costs rise if pipework needs rerouting or a flue has to be moved. It's normal to get two or three quotes before committing, especially for bigger jobs, as prices between local firms can differ quite a bit for similar work.
How long does a boiler installation take?
A straightforward like-for-like combi swap usually takes a day, sometimes finishing by early afternoon if access is easy. If you're converting from a conventional or system boiler to a combi, or the new boiler needs relocating to a different room, engineers often quote one to two days to account for extra pipework, flue work and making good afterwards. Ask upfront how long they expect the job to take and whether you'll be without heating or hot water overnight.
Do I need a Gas Safe registered engineer for boiler work in Nuneaton?
Yes, anyone working on gas boilers, gas fires or gas pipework must be Gas Safe registered by law. Ask to see their Gas Safe ID card before work starts and check the registration number on the Gas Safe Register website, which also tells you exactly what gas work they're qualified to carry out. This matters for insurance purposes too, as some home insurance policies won't pay out on gas-related damage if the work wasn't done by a registered engineer.
What's the difference between a boiler service and a boiler repair?
A service is a routine check, usually annual, where the engineer inspects the boiler, checks for corrosion, tests the flue and gas pressure, and makes sure everything's running safely and efficiently. A repair happens when something's actually gone wrong, whether that's no heating, no hot water, strange noises, or an error code on the display. Keeping up with annual servicing often catches small issues before they turn into an expensive repair, and it usually keeps your manufacturer's warranty valid too.
Can a heating engineer help with a cold radiator or noisy pipes?
Yes, cold spots on radiators are usually down to trapped air or sludge build-up, and an engineer can bleed radiators or recommend a power flush if the whole system's affected. Noisy pipes, sometimes called kettling, often point to limescale or debris around the heat exchanger, particularly in areas with harder water. It's worth mentioning any specific symptoms, like which radiators are affected or when the noise happens, as it helps the engineer diagnose the issue faster rather than charging for a full system inspection.
How do I choose between heating engineers in Nuneaton?
Start by checking their Gas Safe registration number yourself on the official register rather than just taking their word for it. Read through recent customer reviews on public listings, paying attention to how they handled anything that went wrong rather than just star ratings. Ask for a written quote that breaks down parts, labour and any callout charges, and confirm what warranty applies to both the boiler and the installation work. If a business carries our Trust Verified badge, that means it's passed our checks on qualifications, insurance and trading history, but for anyone without it, it's down to you to ask for proof of insurance and qualifications before any work begins.
