Feed in Tariff scheme

The FIT is a scheme in which owners of PV systems are rewarded for every unit of electricity they generate, irrespective of whether they are used on site or not.

This is known as the Generation Tariff and is currently under review. Payments are also made for 50% of every unit generated by the PV system. This is known as the Export Tariff and is currently under review. These payment rates are fixed for 20 years, linked to the Retail Price Index (RPI) and are tax-free. PV systems installed from 1 August 2012 will be subject to an approximate 7% decrease in the FIT rates.
