Changes to the Renewable Heat Incentive tariff rates and scheme came into effect on 1 April 2016

A number of changes to the Renewable Heat Incentive have come into effect.  On 3 March the department of energy and climate change announced changes already made and launched a consultation to evaluate further changes to the scheme [1]. As of 1 April the first round of changes have come into effect.

Tariff rates have increased across the board. Figures from Ofgem [2, 3]

Several changes should make it easier for new applicants to the scheme. Self-built properties are no longer required to be occupied for 183 days. New applicants no longer need to provide a Green Deal Advice Report (GDAR) [4]. Ofgem have released an updated version of their RHI reference document, which contains more information about the scheme [5].

The consultation on the planned changes to RHI remains open until 27 April. The changes are aimed at improving access to the scheme and “Promoting deployment of those technologies which are likely to be strategically important in the longer-term.” However it is possible that solar thermal installations will be removed from the scheme.
