According to the UK government’s Simple Energy Advice website, installing an ASHP in a typical four-bedroom detached house could improve the property’s EPC rating from a D to a B, potentially saving homeowners up to £1,300 per year on their energy bills. Other steps, such as improving insulation and installing double glazing, could be other ways to improve your overall EPC rating.
ASHPs can be effective at improving your EPC rating because they are a renewable energy source that can replace traditional fossil fuel heating systems, which are less efficient and produce more carbon emissions. They also tend to have lower running costs than traditional heating systems such as gas boilers. Running costs are key for calculating a home’s EPC, and so having a heat pump is effective at enhancing the EPC rating while being a good way of bringing down your bills.
It’s important to keep in mind that every property is different, and so while a heat pump may well improve an EPC rating, this will vary according to your current energy usage, your property’s unique attributes, and other specific characteristics.
With strides being taken towards full decarbonisation of the UK’s power grid, a higher EPC rating will likely become more of a norm in the years ahead. Investing in a heat pump, therefore, could be a worthwhile investment for the future.
