RHI (Retail Price Index) payments are based on your estimated annual heat demand, which for heat pumps and biomass boilers, is taken from your EPC. We only provide top quality products, such as Heliotherm, which ensure that you maximise your revenue. The higher your SPF (Seasonal Performance Value), the more energy efficient your system is.

The Department of Energy and Climate Change (DECC) set the rates and any tariff reduction will only affect people who have applied after the degression date. The rate is reviewed every quarter.

Currently, from 1st April 2016, the RHI is:

• Ground source heat pumps is 19.33p
• Air source heat pumps is 7.51p

This will be reviewed on 1st June 2016.

Your first payment can be expected three months after your date of application.
