New boiler FAQ's

How much can a new boiler reduce your energy bills by?

This largely depends on the efficiency of your current boiler and how much energy you use. For example, you could save as much as £840 per year if you are upgrading from an old G-rated boiler to a modern A-rated boiler (along with a programmer, room thermostat and thermostatic radiator controls (TRV's)). For more details, check the Energy Savings Trust website.

How much does it cost to install a new boiler?

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.

How long does it take to install a replacement boiler?

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.

Can I get a new boiler on finance?

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.

Can I get finance with poor credit?

Yes, we can certainly try to. Heatable works with a panel of lenders, so, if for whatever reason you didn't pass with our primary lender, we will pass it over to a secondary who will be able to assist.

What if I change my mind, or need to cancel?

That's not a problem. If for whatever reason you change your mind, or need to cancel your install, you can do so without any fees. If you have paid any monies via card, we will refund this directly back to your account.

Who'll be installing my boiler?

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.
