If you’re considering switching from a fossil fuel boiler to air source heat pump technology you’ll need an up-to-date Energy Performance Certificate (EPC). In this blog we explain what an EPC is and why you need one.

With Britain committed to bringing carbon emissions to net zero by 2050, and with the recent announcement of the Green Homes Grant, uptake of air source heat pump technology is on the rise. Your home’s energy efficiency plays a key part in determining your suitability for air source heat pump technology and that’s where an EPC comes in.

What is an EPC?

An EPC is a report which provides information on your home’s energy use and how energy efficient it is. EPC reports grade your home’s energy efficiency on factors such as its insulation, doors and windows. Your home is then given a rating from A-G, with A representing the most energy efficient homes and G representing the least. The higher your home’s energy efficiency, the lower your energy bills are likely to be.

Why do I need an EPC?

Unlike traditional boilers, which can support large fluctuations in temperature by switching on and off throughout the day, air source heat pumps work best when maintaining a constant, comfortable level of warmth for you and your family. As a result, it’s vital that your home is well-insulated and energy efficient before your heat pump is installed.

To find out whether your home is ready for an air source heat pump, we’ll need to look at your home’s energy use and whether your insulation needs improving, which is why you need an EPC.

The EPC also tells us how much energy is needed to heat your hot water supply and helps us calculate the RHI payments you can expect to receive. It is also worth noting that an EPC is a mandatory requirement when applying for RHI.

What is an RHI payment?

RHI stands for Renewable Heat Incentive – a payment scheme awarded to homeowners who adopt air source heat pump technology. Payments are made quarterly and last for seven years. How much you get paid depends on the amount of clean energy your home uses. Anyone who installs a boiler powered by air source heat pump technology qualifies for these payments.

What if I don’t have an Energy Performance Certificate?

If you don’t have (or can’t find) your Energy Performance Certificate our expert team can arrange one for you. You’ll also need a new EPC if your existing one is more than two years old.
