Replacing like for like, or changing the system
A like-for-like swap, in the same position and the same type, is the simplest and quickest job. A change such as replacing a regular boiler and tanks with a combi, moving the boiler, or changing the flue route involves more work, and is assessed at the survey and priced before you agree. See boiler conversions and combi, system or regular?
Repair or replace?
A fault does not always mean a new boiler. If the boiler is old, keeps breaking down or parts are hard to find, replacement can cost less over time. If you are unsure, book a diagnostic visit first: £92.50 for the first 45 minutes. See repair or replace your boiler?
