What is our commercial RHI calculator?


This easy to use spreadsheet allows you to input the installed cost of a biomass boiler system and shows your potential commercial RHI payments, fuel savings and the payback from the investment. The figures are expressed in both annual terms and as a total for the 20-year duration of the scheme.

As a guide, an estate with main house and offices with a 198kW biomass system would enjoy payments of approximately £15,000. A farm house with its own holiday lets using a 100kW system would receive approximately £7,000 or more per annum for the 20-year duration of the scheme.
