Sheffield's boiler specialists
Annual boiler servicing that keeps you safe and warm
An annual boiler service is the single best way to keep your heating reliable, your bills down and your warranty valid. A neglected boiler works harder, costs more to run and is far more likely to break down on the coldest day of the year — usually when engineers are hardest to get hold of.
Heat365 has serviced and maintained boilers across Sheffield and South Yorkshire for over two decades. Our Gas Safe registered engineers service all makes and models — Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm and more — and leave you with a full written service record every time.

"Needed a new boiler installed asap, got in contact with Ricky. Straight away he quoted & fitted me in quickly. The lads stayed for 10 plus hours and returned the next day to ensure I had water and heating. Can't fault the lads at all."

"Great service, responded quickly and sorted my boiler out so I had heating and hot water back on in this freezing weather. Came out late on a Saturday night to fix. NHS discount too!!"

"Thank you to Rick and the team for fitting our new boiler and radiators. I waited a while before leaving a review, but 6 months down the line it's still working just as good. I would highly recommend."

FAQs
Boiler servicing in Sheffield — your questions answered
Can't see your question? Call 07534 793949 — we're happy to help.
How often should I service my boiler?
For most homes an annual boiler service is recommended. It's usually a condition of your manufacturer's warranty and the best way to keep your boiler safe, efficient and reliable. Skipping services can lead to higher bills, more breakdowns and even an invalidated warranty.
What's included in a Heat365 boiler service?
A full inspection of the boiler, flue and ventilation, gas pressure and flow checks, a combustion test with a flue-gas analyser, testing of all safety controls, cleaning key components where needed, leak and corrosion checks, and a written service record. It's a proper service — not a ten-minute glance.
How much does a boiler service cost in Sheffield?
We confirm a clear, fixed price before booking, based on your boiler type and whether you need a landlord certificate. For realistic price ranges, see our Sheffield boiler service cost guide, or call us for an exact quote.
How long does a boiler service take?
A standard annual service usually takes around 30–60 minutes, depending on your boiler's type, age and condition. Older or back boilers can take a little longer as they need more thorough cleaning and checks.
Do you service all boiler makes and models?
Yes — our Gas Safe engineers service all major brands including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm and Viessmann, across combi, system and regular boilers.
Do you provide landlord gas safety certificates?
We do. We issue annual landlord gas safety records (CP12) for rental properties across Sheffield and South Yorkshire, and can carry out the boiler service at the same visit to save you time and money. Our full guide to landlord boiler servicing explains what an engineer checks, what the CP12 certificate covers and your legal duties as a landlord.
What happens if you find a fault during my service?
We stop, explain what we have found in plain English and quote before doing any extra work — nothing gets done without your say-so. If the boiler needs more than a minor adjustment, that becomes a repair visit: see our boiler repair in Sheffield page for how that works.
