Fully Funded Air Source Heat Pump Grants
An Air Source Heat Pump is a type of renewable heating system that extracts warmth from the outside air, even on cold days. It transfers that warmth into your home to heat your space and hot water.
How Do Air Source Heat Pumps Work?
ASHPs work much like a refrigerator, but in reverse: rather than removing heat, they take heat from the outdoor air and bring it inside, making them an ideal solution for the chilly UK climate! They are a highly efficient and eco-friendly way to heat your home.
Also extremely cost effective, running at between 300-400% efficient on average. So for every KW of electricity put in 3-4kwh are produced for the property.

Frequently Asked Questions
Air source heat pumps can be more expensive to run than mains gas boilers if you're comparing to a newer gas boiler(90% efficient), but they are generally cheaper to run than other heating systems like oil,LPG or electric storage heaters.With Solar PV this is reduced further.
Air source heat pumps do produce some noise, typically a low hum between 40 and 60 decibels, which is comparable to a refrigerator or a dishwasher. And quieter than an Oil boiler.
ASHPs transfer heat from the outside air to your home's heating system. They work by absorbing heat from the air, even at low temperatures, and using it to warm a refrigerant. This warmed refrigerant is then compressed, increasing its temperature further, and this heat is transferred to your home's heating and hot water system.
Yes, air source heat pumps (ASHPs) can heat both your home's central heating system and your domestic hot water.
Yes The UK government's target is to install 600,000 heat pumps per year by 2028 as part of its efforts to decarbonize domestic heating. Along with it’s commitment to phase out oil and gas boilers, Heat pumps will be one of the main heating sources for properties in the next few years.
