New boiler FAQ's

When buying a new boiler through Heatable, am I protected?

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 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?

You'll receive details about your engineer prior to your install, including photo ID, so you know who to expect.

Is your calendar guaranteed after I've picked my date?

Our booking calendar is a live system which checks the real-time availability of engineers in your area, so it should be bang-on. On the rare occasion that the date has been double booked, or there's an error, we'll be in touch to arrange an alternative or discuss your options.

Do I need scaffolding to install a boiler?

Generally, no. If your boiler is in a typical home with two floors, scaffolding won't be needed. If your flue is located above a conservatory or in a particularly high section of your roof, it'd be best if we check first. You can submit an eSurvey and upload some images for us to run through before you book.

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)).
