General advice

Do your research

Do some research on different types of boilers and decide which one suits your home best. There are combi boilers, system boilers and conventional boilers to choose from.
Once you’ve decided on the type of boiler you need, you can have a look at the different brands. Worcester Bosch, Valliant and Glowworm are popular brands of boiler.

Costs

Installation costs

Boiler costs depend on the make, model and type of boiler you want. It will also depend on how straightforward the installation is. Here are some of the approximate installation costs for typical boiler installs:

  • Replacing a condensing combi boiler in the same position as the old one: £540-660
  • Swapping a non-condensing boiler with a condensing one in the same position as the old one: £640-770
  • Replacing a new condensing boiler in a different place and adding radiator valves and controls: £1,140-1,440

Savings on gas bills

A new boiler is a significant investment, so you need to ensure that you’re aware of the costs involved. It’s worth remembering that you’ll also save money if you update an old boiler with a new A-rated one:

Old boiler rating Savings per year
G (<70%) £210
F (70%-74%) £145
E (74%-78%) £125
D (78%-82%) £110

These savings are based on a semi-detached house replacing an old boiler with a programmer, room thermostat and thermostatic radiator valves (TRVs).
