Non-domestic RHI reaches 1GW milestone in the UK

The non-domestic Renewable Heat Incentive reached a major milestone on the 15th August, with 1 gigawatt (GW) of renewable heat now available through 4,926 accredited wood heating installations in the commercial, industrial and public sectors, at locations including farms, factories, care homes, hotels and churches.

The RHI is a government finance scheme that provides financial incentives to homeowners to increase the production of renewable heat. The non-domestic sector provides a subsidy, payable for 20 years, to eligible renewable heat generators in the UK.

The RHI has had a significant impact on investments in renewable heat—particularly bioenergy—and those investments are forecasted to significantly increase over the next several years. DECC statistics indicate that between 2010 and 2012, £760 million was invested in heat from bioenergy, or 56% of the total investment in renewable heat over the period. That share is expected to increase to 85% from 2013 to 2020.

Julian Morgan-Jones, interim chairman of the newly launched Wood Heat Association, said 1 GW of wood heating under the RHI is “a major breakthrough. Our industry is growing fast, from boiler manufacturers and installers to fuel producers and distributors. We want that growth to be both successful and sustainable.”

Morgan-Jones added that as well as stability in the RHI, more work needs to be done on upskilling system installers and developing widely accepted installation standards for all boiler sizes.

SBS works closely with a range of technical partners, including PPL Training and NICEIC, to upskill installers of all renewable technologies. Our partners can provide the whole solution for installers wanting to become part of the increasing RHI market, from high quality training to certification. For more information, email
