London Boiler Installations
We created 123 Heat with a clear goal in mind; to offer our customers across London the fastest and simplest way to replace and upgrade a boiler. So that’s what we do. We normally fit your new boiler the next working day, or at a time that suits your schedule.
How do we make this happen? 123 Heat engineers will ask for some info about the boiler you’ve got at the moment, and your home, to find out which boiler replacement would be right for your needs. Then we’ll select the right pricing plan – our 0% finance plan offers 12 monthly instalments with a minimum 10% deposit.
Then you choose the best time for our Gas Safe registered engineers to carry out your boiler installation in your home. Sorted!
