FAQs

The cost of a new boiler depends on a variety of factors, including the type of boiler you select, your location and the complexity of your installation.
Yes, in more ways than one. First, we're a Which? Trusted Traders which means we have to work to their strict standards and guidelines. Secondly, we're Gas Safe Registered, and so are all of the installers who fit for us. We're also fully insured, giving you total peace of mind.
On average installing a new boiler takes between 1 to 2 days to complete. If you are having your old boiler replaced in the same location and with the same type of boiler the process will be quicker (likely one day) compared to installing a different type of boiler in a new location.
Yes, you can. All of our installations have finance options available. You can spread the cost over 3, 5, 7 or 10 years at a rate of 11.9% APR. Or, you can spread the cost with 0% APR up-to 4 years on certain packages. Deposits are optional.
All of our installation partners go through a lengthy and strict Which? Trusted onboarding process. They're fully insured, highly rated and carry a unique set of skills to get your job, done.
