Boiler installation & replacement

A New Boiler, Fitted Properly

If your boiler's getting on, breaking down or costing a fortune to run, a new one pays for itself in reliability and lower bills. SWW installs and replaces boilers for homes right across Exeter and Devon — all carried out by Gas Safe registered engineers, with a fixed price agreed before we start.

We'll talk you through the right boiler for your home and budget rather than pushing the most expensive option, fit it cleanly and tidily, and leave you with a system that just works. No mess left behind, no surprises on the bill.

Which boiler?

The Right Type For Your Home

Not sure what you need? That's what the free survey is for — but here's the short version.

Combi Boilers

Heating and hot water on demand from one compact unit, no tank needed. Ideal for most homes and smaller properties where space is tight.

System Boilers

Work with a hot water cylinder to supply several taps and bathrooms at once — a better fit for busy family homes with more than one bathroom.

Regular / Heat-Only

The traditional setup with a tank in the loft and a cylinder. Often the sensible swap for older properties already plumbed this way.

When to replace

Signs It's Time For A New Boiler

Rising bills, radiators that take an age to warm up, banging or gurgling noises, a boiler that keeps losing pressure or cutting out, or one that's simply over 10–12 years old — all signs it's on its way out. If yours has broken down completely, we can talk you through whether a repair or a replacement makes more sense for the money.

We fit quality boilers from trusted manufacturers, registered for their full parts-and-labour warranties so you're covered for years to come.

Common questions

Boiler Installation FAQs

How much does a new boiler cost in Exeter?

It depends on the boiler type and your home, but we give you a fixed written quote after a free survey so you know exactly where you stand before committing. No obligation.

How long does a boiler replacement take?

A straightforward like-for-like swap is usually done in a day. If we're moving the boiler or changing the system type, it can take a little longer — we'll tell you upfront.

Do you remove the old boiler?

Yes — we take the old boiler and any waste away and leave everything clean and tidy. You won't be left with anything to sort out.

Are you Gas Safe registered?

Yes. All our gas and boiler work is carried out by Gas Safe registered engineers — the legal requirement for anyone working on gas in your home.
