For upto date Feed-Tariff rates, please go here.

Here are the basic details from the Energy Saving Trust:

The UK Government's Department of Energy and Climate Change (DECC) recently held a consultation on a review of the Feed-In Tariffs scheme (FITs). On 17 December 2015 they published their response which included new, reduced tariffs for domestic-scale solar PV systems which will come into force from 15 January 2016 for new installations.  Those already receiving FITs are unaffected by the changes. FITs tariffs already published by Ofgem under the existing FITs scheme rules will apply from 1 January 2016 to 14 January 2016. From 15 January 2016 the new, reduced tariffs will apply. There will be a pause in the FIT scheme from 15 January to 7 February (inclusive), during which time no new installations will be FIT accredited. Any installations made in this period will be placed in a queue until the new tariffs come into force on 8 February.

A number of additional changes are being made to the FITs scheme and further information will be given by EST. Until then you can refer to the full details of the proposed changes and consultation documents on DECC’s website which are also summarised in the changes to renewables subsidies press release.
