The Renewable Heat Incentive (RHI) for non-domestic properties

The Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies among householders, communities and businesses through the provision of financial incentives.

The commercial Renewable Heat Incentive is aimed at non-domestic properties such as churches, hotels, schools and commercial premises. There is also a domestic Renewable Heat Incentive scheme which was launched in the spring of 2014.

The UK Government expects the RHI to make a significant contribution towards their 2020 ambition of having 12 per cent of heating coming from renewable sources.

The scheme will pay the owners of eligible propoerties for each kWh of heat generated by an eligible installation significantly reducing payback periods for renewable heating technologies.

In a typical arrangement with a 30kW ground source heat pump, you could be generating approximately 70,000 kW. This would provide an approximate revenue of £3,290.00. Please note you would need to allow for the cost of electricity to run the heat pump, we estimate in this scenario it would equate to £2,000 depending on your tariff arrangement.

For a solar thermal installation estimated at producing 9,000kW/h your subsidy could be in the region of £800.00. If you consider then what you would save by not using oil - approximately £500.00 you can work out your overall saving of £1,300.00.
