Frequently asked questions

The cost of a new boiler can vary depending on the type and size of boiler you need, but you could have a brand new A-rated boiler installed from £1,795 with BOXT. Get your fixed price quote, plus a recommendation on the right boiler for your home and budget.

The easiest and speediest boiler installation involves switching an old boiler for a new boiler of the same type in the same place in your home. These installations can be completed on the same day and usually take around 6-8 hours.

However, if you need to switch to a different type of boiler, or want it installed in a different location then it can take a little longer. As a guide:

  • Relocating a boiler: Adds half a day to a standard installation
  • Changing the type of boiler: Can take up to 2 days
  • Changing the type and position of your boiler: Can take up to 4 days

BOXT has a comprehensive guide on how long it takes to replace a boiler for more information.

We're working together with BOXT, one of the largest boiler installation companies in the UK, to take better care of your home. Your new boiler will be fitted by BOXT’s friendly Gas Safe engineers.
