Moving the boiler, converting to a combi, or replacing old pipework can add to that. We'll tell you at the survey, so there are no surprises on the day.

How long does a boiler installation take?
A straight swap usually takes one to two days. A conversion or a boiler move takes longer. We'll give you a timescale with the quote.
Which boiler should I get?
It depends on the size of your home, how many bathrooms you have and how much hot water you use. We'll recommend one at the survey and explain why.
Is the price fixed?
You get a written quote after the survey. If anything changes once work starts, we talk to you before doing it.
