What Does a New Boiler Cost in the South West?

09th Nov 2026 4 minute read

If you’ve searched for the cost of a new boiler, you’ll have seen all sorts of figures. The truth is, nobody can tell you what yours will cost without knowing your home, and homes across the South West vary more than most.

A modern semi in Exeter, a granite cottage on the edge of the moor and a seaside bungalow all need something different from their heating. In this guide, we’ll explain what shapes the price of a new boiler here in the South West, and how you can get a fixed price for your own home online, in just a few minutes.

What shapes the price of a new boiler in South West homes

Older and character properties. The South West has lots of older homes with thick stone walls, solid floors and pipework that’s been added to over the years. These can need a little more work to get the new boiler fitted neatly and running at its best.

Coastal weather. Salty, damp air near the coast is hard on anything fitted outside, like flues and condensate pipes. Getting these right first time helps your new boiler last.

The right boiler for your household. A combi heats water on demand and suits many smaller homes. A system or conventional boiler with a hot water cylinder can be a better fit for bigger families or homes with more than one bathroom. Holiday lets and annexes can have different needs again.

Swap, upgrade or move. Replacing a boiler in the same spot is the simplest job. Changing boiler type, or moving it to a new spot, involves more pipework and a new flue.

Looking after your system. Cleaning out the old system and fitting a filter protects your new boiler and keeps the warranty valid.

Off the gas grid? Many homes in the South West aren’t on mains gas. If that’s you, give our team a call and we’ll talk you through your options.

Your questions answered

Do I need a survey before I get a price? No. Our online quote tool gives you a fixed price without a surveyor visit.

Should I repair my old boiler or replace it? If your boiler is getting on in years, keeps breaking down, or parts are hard to find, replacing it is often the better choice. A new, efficient boiler can also help bring your heating bills down. Not sure? One of our engineers can give you an honest view.

Is a combi boiler right for my home? Combis suit lots of homes, but not all. If you have a big household or more than one bathroom, a system boiler might suit you better. Our quote tool recommends the right type for your home.

How do I keep my new boiler running well? Get it serviced every year by a Gas Safe engineer. A Care Plan takes care of this for you and keeps your warranty on track.
