The cost of new boiler installation in your home can vary. For example, if you are looking to change your old boiler by installing a new gas condensing combi boiler, you can expect to pay around £600. For installation in the same location.

If you need to relocate your new boiler to somewhere different in your home, then the cost of this installation will rise dramatically. You could end up paying as much as £1500, sometimes even more, if it’s a particularly awkward move.
