With lots of free grants, discounts and incentives now might be the best time to have a heat pump installed. Currently there's about £10,000 to be had in Govt grants and freebies from the banks and Octopus (not means tested).Currently Octopus Energy has 15% off and a £100 e-visa if you use my link. It doesn't matter if your home is poorly insulated, these deals include bringing your home up to standard. You will also be helping the planet as they are roughly 300% more efficient than a gas boiler and you will be saying goodbye to the gas standing charge which is over £100 a year.
