The Renewable Heat Incentive
What is it and how can it help you?
This website will tell you everything you need to know about the RHI, the products that qualify and a breakdown of just how much you can save.
In April 2014, the Government launched the Renewable Heat Incentive (RHI) for homeowners.
The scheme pays fixed quarterly tax-free tariffs to homeowners for seven years after the installation of renewable heating technologies.
People who live in homes off the gas grid have the most potential to save on fuel bills now and far into the future as well as decreasing their carbon emissions. But it is also beneficial to people who own period properties or rely on LPG or oil as their fuel source.
The RHI scheme covers single domestic dwellings and is open to homeowners and self-builders in England, Scotland and Wales.
To see if you can benefit, and to work out how much you could save, you first need to understand which renewables would work for you and whether you meet the Government criteria.
The Domestic RHI Tarrifs
The tariff rate is multiplied by the estimated annual heat load figure taken from your EPC, which is divided by four to generate a quarterly figure.
Heat pumps need an extra calculation to analyse their efficiency. This is done using the heat pump’s Seasonal Performance Factor (SPF) which converts the estimated annual heat load into the estimated renewable heat load.
To be eligible, all heat pumps must have a minimum SPF of 2.5.
Heat pumps must also use a compressor (a component which raises the temperature of the liquid that the heat is transferred to within the technology) driven by electricity.
The domestic RHI will pay you the following tariffs per unit of heat generated for seven years (on a quarterly basis):
