Legacy application make up the bulk of first 10,000 RHI accreditations

Posted by Cathy Debenham on 6 November 2014 at 3:22 pm

South west England has the most accreditations (1,847) under the new domestic renewable heat incentive (dRHI) according to new statistics from Ofgem. Renewable heat was nearly as popular in Scotland (1,596 accreditations), with south east England next. Not surprisingly London was the region with the least accredited systems, with a paltry 181.

Ofgem released the statistics early this month to celebrate the first 10,000 systems to be accredited. It reached this milestone just before the first six months of the scheme were up. 

While this seems like a big number, it doesn't reflect a huge rush to install renewable heat. Rather it is the result of five year's worth of legacy applications from people who have installed since the scheme was announced in 2009, and its opening for business in April this year. Of more than 2,500 accreditations per month for the past three months, around 500 a month were new installations.

Any owners of legacy applications who haven't applied for the dRHI yet have until 8 April 2015 to submit their applications.

Air source heat pumps proved to be the most popular technology with 3,688 installed. This was followed by solar thermal, then biomass, with ground source heat pumps least popular. However, if broken down into legacy and new installations the spread of technologies changes. Biomass accounts for 44 per cent of new installations, and just 17 per cent of legacy ones. 














Nearly half of dRHI claimants have swapped from oil heating to their new renewable heating. Mains gas and electricity were the next most significant former types of heating. Getting on for three quarters of those benefitting from the scheme are likely to be living off gas grid, which is the priority area for the dRHI.
