The government’s proposed changes to feed-in tariff rates have been successfully challenged in the High Court and the Court of Appeal. However, the government is now considering appealing to the Supreme Court, and so the ultimate outcome is still not yet certain.
The current status for domestic scale solar PV systems is as follows:
All systems installed up to and including December 11, 2011, will receive the old higher tariff rate for the full 25-year tariff lifetime. This will be 43.3p/kWh for retrofit systems and 37.8 p/kWh for systems installed as part of a new home.
All systems installed on or after March 3, 2012, will receive the old rate until March 31, 2012. Then the new lower rate of 21p/kWh applies for the remainder of the 25 years. The new rate is the same for retrofit and new-build schemes.
For systems installed from December 12, 2011, to March 2, 2012 inclusive, the rate will depend on the final outcome of the current legal proceedings. They will receive either:
• The old higher rate for the lifetime of the systems, or:
• The old rate until March 31, 2012, and then the new lower rate for the rest of the 25 years.
The export tariff of 3.1 p/kWh remains unchanged.
All tariffs above are quoted at 2011/12 prices. They will all increase in line with RPI on April 1, 2012, and every subsequent year.
Tariffs for other technologies are not affected by the current review, but some are already planned to decrease by a modest amount for new systems installed on or after April 1, 2012.
The date of installation for the purposes of determining the tariff is the date on which the FiT supplier (the electricity company) receives a complete FiT application, including MCS certificate supplied by the installer.
