Air source heat pumps now eligible for the non-domestic RHI

Non-domestic RHI air source heat pump tariff 2.5p/kWh

Air source heat pumpSource Energy are pleased to share the fantastic news from the Department of Energy and Climate Change (DECC) regarding the non-domestic Renewable Heat Incentive (RHI). This scheme will now include air to water source heat pumps, and will offer a tariff of 2.5p/kWh for 20 years for installations from 2nd December 2013.

This is a significant increase from original proposals of 1.7p/kWh, helping make this renewable energy technology more attractive to businesses, who want to reduce their carbon emissions whilst benefiting financially. Air source heat pumps are a fantastic option when site space is limited and can often be integrated into existing properties.

This new single tariff has two tiers:

Tier one: 8.7p/kWh for the ‘initial’ 15% of heat i.e. 1,314 hours over a 12 month period.

Tier two: 2.6p/kWh for the remainder 85% of heat.

This 20 year tariff will be available for eligible commercial ground source heat pump installations commissioned from 21st January 2013.


These non-domestic RHI changes are expected to come into force from spring 2014.
