Renewable Heat Incentive Scheme

The Renewable Heat Incentive (RHI) is a cash payment scheme which pays for every unit of heat generated through renewable sources, in a similar way to the Feed-in Tariff but limited to heat generating technologies such as Heat Pumps or Solar Thermal Panels. The domestic tariff is guaranteed for 7 years and will rise in line with the retail price index (RPI). The scheme began on 9th April 2014 and all ‘legacy’ installations will be eligible. The commercial tariff is guaranteed for 20 years and began in November of 2011.

If you already have a WDS Green Energy installation, more information on how to apply for the RHI can be found here

Renewable Heat Incentive – Continues until March 2021

WDS Green Energy welcomes the Government confirmation of the continuity of the RHI until 31 March 2021.



The Government is planning to introduce limits on the amount of renewable heating above which Domestic RHI will not be paid:

The limit for ASHP installations will be 20kWh – up to £1,337 a year for 7 years = £9,498
The limit for GSHP installations will be 30kWh – up to £4,206 a year for 7 years = £29,442

Eligible Technologies and Tariff Levels

The renewable heat incentive qualifying technologies and tariff rates are shown in the table below

The commercial (or non-domestic) RHI tariff provides financial support for the lifetime (20 years) of the qualifying installation. Payments are made quarterly and are based upon the actual heat output of the system i.e. the system is metered. An Eligible Heat Output (EHO) figure in kWh is calculated through the provision of meter readings at three monthly intervals. This is the amount that will be multiplied by the tariff rate to determine the payment amount.
