        New Boiler FAQs

        The final cost of a new boiler installation depends on several factors, including your location in the UK, the type of boiler, and the model or brand you choose. At Heatable we offer fixed price quotes, as well as finance allowing you to spread the cost of a new boiler into monthly installments.
        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.
        Yes, we do. In fact, we offer finance on everything. That's including low-rate interest-bearing finance, interest-free credit finance, buy now pay later, Klarna... and others. On the renewables side, we recently secured over £100m in funding via a specialist bank which has been set aside to break down the barriers for homeowners who're looking to crush their bills.
        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.
        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. You'll receive details about your engineer prior to your install, including photo ID, so you know who to expect.
