Tariff degression

How the tariff levels will change for people installing systems after April 2012

Once a system has been installed and registered for the Feed-In Tariffs, the tariff levels are fixed and subject only to index-linking for inflation as described in our information on duration and variations.

However, some technologies are expected to get cheaper as volumes build in the future, so the Government has decided to adjust some tariff levels for systems installed after April 2012.

The future levels have been defined as shown in the table shown below. You can download a full size version here and that also gives a link to the official version by the scheme administrators Ofgem.
