"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!!"

FAQs
New boiler installation in Sheffield — your questions answered
Can't see your question? Call 07534 793949 — we're happy to help.
How much does a new boiler cost in Sheffield?
It depends on the boiler type, your home and whether it's a straight swap or a conversion. We give you a single fixed price after a free survey — no hidden extras. For realistic price ranges by boiler type, see our Sheffield boiler installation cost guide.
How long does a boiler installation take?
Most straightforward boiler swaps are completed in a single day. Conversions (for example system or back boiler to combi) or relocations can take a little longer — we'll tell you exactly what to expect at your survey.
Which boiler is best — combi, system or regular?
It depends on your home's size, water pressure and how much hot water you use. Combi boilers suit most Sheffield terraces and semis, while system or regular boilers are better for larger homes with several bathrooms. We'll recommend the right option at your free survey.
Do you remove my old boiler?
Yes — removal and responsible disposal of your old boiler, plus a full tidy-up, are included in every installation quote. We protect your home while we work and leave everything clean.
What warranty do new boilers come with?
Depending on the brand and model, new boilers come with manufacturer warranties of up to 10 years. We register the warranty for you — keeping it valid simply requires an annual boiler service.
Can you convert a back boiler or system boiler to a combi?
Absolutely. Converting an old back boiler or system boiler to a modern combi is one of our most popular jobs — it frees up space by removing tanks and cylinders. We'll assess your pipework and give you a clear fixed price.
Do you notify Building Control and provide a certificate?
Yes. As Gas Safe registered installers we notify your installation to Building Control and you receive a Building Regulations compliance certificate, along with your warranty registration and commissioning paperwork.
