A new boiler, fitted right

Whether it's a straight swap for a failing boiler or a full system change, SWW installs and replaces boilers right across the South West, all by Gas Safe registered engineers.

We're not tied to one manufacturer. We fit Ideal, Vaillant, Worcester Bosch, Baxi and the other major brands, and we'll recommend the one that actually suits your home and budget rather than the one we'd rather sell you. Fixed price agreed after a proper survey, old boiler taken away, and everything registered so your manufacturer warranty is valid from day one.

If you already know you want an Ideal or a Vaillant, we're accredited installers for both. See our Ideal boiler and Vaillant boiler pages for the detail on warranties and models.

What suits your home

Combi, system or heat-only

Not sure which type you need? That's what the survey's for.

Combi boiler

Heating and hot water from one unit, no tank needed. The most common choice for smaller and mid-sized homes.

System boiler

Works with a hot water cylinder, better suited to homes with higher hot water demand or multiple bathrooms.

Heat-only (regular)

The traditional setup with a cylinder and tank, often the right replacement for a like-for-like swap in an older system.

Common questions

Boiler installation South West FAQs

Do you install boilers outside Devon?

Yes. We install boilers right across the South West, in Devon, Cornwall, Somerset, Dorset and Bristol, Gas Safe registered and fixed price on all major brands.

Which brands do you fit?

All the major ones: Ideal, Vaillant, Worcester Bosch, Baxi and others. We're accredited installers for Ideal and Vaillant specifically, which unlocks longer warranties on those ranges, but we're not tied to a single brand and will recommend what actually suits your home.

How much does a new boiler cost?

It depends on the boiler, your home, and whether the system needs any extra work. We give you a fixed written quote after a survey so you know exactly where you stand before committing.

Do I get a warranty?

Yes. We register every boiler we fit so you get the full manufacturer's warranty, and on Ideal and Vaillant installs our accreditation can extend that further.

How long does an install take?

A straight swap is usually a day. Moving the boiler or changing system type takes longer. We'll give you a clear timescale with the quote, wherever in the South West you are, and take the old boiler away when we're done.
