Why Keynsham Homeowners Choose Us for Boiler Installation
We know people are careful about who they let into their homes — especially when it involves the heating. Here’s what you can expect from us.

Honest, Fixed Pricing
We give you a written quote before any work starts. That’s the price you pay. Like-for-like boiler swaps start from £2,500 including VAT — see the full price breakdown. No extras tacked on at the end, no awkward conversations on the day. If something unexpected comes up during the install, we talk to you first.
Clean, Respectful Work
Dust sheets go down before we start, and everything gets tidied up before we leave. We don’t leave a mess. Your home should look the same as it did before we arrived — just with a better boiler on the wall.
Proper Communication
We tell you what we’re doing, when we’re doing it, and how long it’ll take. If the job runs over, you’ll know why. We don’t disappear for three hours and hope you won’t notice.
Local and Reliable
We’re based nearby, not in a call centre somewhere else. If you need us after the install, you can actually get hold of us. That matters — especially in the middle of January when your heating goes off.

Thinking About a Boiler Replacement in Keynsham?
Keynsham sits right between Bath and Bristol, and that’s shaped both the town and its housing. There’s the older core with Victorian and Georgian stone terraces, big waves of interwar and post-war semis built as the town grew, the streets that went up around the old Fry’s chocolate factory, and newer riverside developments. Plenty of Keynsham homes are now on their second or third boiler, and a lot of the older systems are well past their best.
Because the stock is so mixed, the right boiler really depends on the house. A compact terrace near the centre is usually best suited to a combi — hot water on demand, no tank, and it frees up cupboard space. A larger semi or family home with more than one bathroom often works better on a system boiler with a cylinder. We size it properly for your home rather than guessing, so you get a boiler that keeps up without burning gas for nothing.
Keynsham gets the area’s hard water off the limestone, so scale build-up is a real factor in how long a boiler lasts here. Every install includes a full system flush and a scale-reducing filter as standard. Want to keep your new boiler in top shape afterwards? We also offer boiler servicing in Keynsham and fast repairs. If you’re weighing up lower-carbon heating, we fit air source heat pumps too and will give you honest advice.
You’ll get a fixed price agreed in writing before we start and tidy work from a local Gas Safe engineer. Compare us with our main boiler installation in Bath service, or book an annual service.
Combi Boilers
The most popular choice for homes in Keynsham — especially the two and three-bed terraces and semis. A combi heats water on demand, so there’s no cylinder taking up space in the airing cupboard and no tank in the loft. Compact, efficient, and straightforward.
System & Regular Boilers
System Boilers — Better suited to larger homes with more than one bathroom. If you’ve got a four-bed on one of the newer estates, a system boiler with a hot water cylinder handles the demand without losing pressure.
Regular Boilers — If you’ve got an older property with a traditional heating setup — gravity-fed system, tanks in the loft — a regular boiler might be the best fit. We see these a lot in the older Keynsham homes.
