Renewable Heat Incentive Premium extended

However, DECC also said the Renewable Heat Incentive, which pays people for every unit of heat generated by renewable sources, is not likely to be made available to domestic properties until summer 2013.

Commercial installations already qualify for the RHI and it was hoped that homeowners would be able to join the scheme sometime this year.

David Parry-Jones of Knight Frank’s Building Consultancy team said: "Although extending the RHI Premium will be helpful for anybody looking to install a system, we would have preferred to see the RHI payment itself coming into place rather than being delayed again."

DECC has also announced it will be consulting on measures to help control the cost of the RHI. It said these could include lowering tariffs as the scheme grows and allowing the scheme to be suspended for new entrants if 80% of the available budget is expected to be spent.

Benjamin Davies of Knight Frank’s Renewable Energy Team said: "Clearly costs have to be kept under control, but DECC needs to clarify the situation quickly so we avoid the uncertainty that badly affected confidence in the Feed-In Tariff scheme for renewable electricity."
