Although Air Source Heat Pump Grants England may be available from the Affordable Warmth Scheme from 1st January 2020, the main financial incentive for installing air source heat pumps is the Domestic Renewable Heat Incentive.
The Domestic Renewable Heat Incentive pays tariffs every three months for seven years if you install an air source heat pump and comply with the regulations.
The current RHI tariff for air source heat pumps is 10.71 pence per kilowatt hour (kWh) and is based on the Heat Demand figure from your Energy Performance Certificate (EPC). You can view your EPC HERE.
