Heat pumps qualify for the Renewable Heat Incentive (RHI) which provides regular quarterly income payments direct to your bank account. These are tax-free, index-linked and designed to recoup your installation costs over the seven-year duration of the RHI.
The amount you receive varies depending on the amount of renewable heat your system generates and the type of heat pump installed. Ground-source heat pumps receive larger payments than air source (19.1p per kWh of renewable energy compared to 7.42p per kWh) which reflects the difference in installation costs.
