RHI: Domestic

The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use naturally replenished energy can help the UK reduce its carbon emissions. Domestic Renewable Heat Incentive.

Key to joining is that the renewable heating system heats only a single property which is capable of getting a domestic  Energy Performance Certificate (EPC). The EPC is the proof we need that your property is assessed as a domestic ‘dwelling’. Without one, you won’t be able to apply and can’t join the scheme.

An EPC gives information about a property’s energy use, plus recommendations on how to reduce energy and save money. It’s required every time you buy, sell or rent a property. It’s included as part of a Green Deal Assessment, which is a requirement for most to join the Domestic RHI.

Domestic RHI payments are determined by the estimated annual heat load (from EPC), they are paid for a period of 7 years.

Non metered biomass systems are deemed that all heat produced is counted as renewable. We multiply the tariff rate by the estimated annual heat load figure (in kWh) taken from the Energy Performance Certificate (EPC). Divide by four for a quarterly figure.

Example

35,000kWh x 7.14p/kWh = £2,499 /4 

£624.75 per quarter. 

Metered biomass systems are sometimes necessary for various reasons such as having a fossil fuel backup boiler installed on the same system, in these cases your payment will be calculated by meter readings.

For metered systems, we multiply the Domestic RHI tariff rate by the eligible renewable heat generated that quarter.

Payments will be capped annually at the amount the heating system could receive were it not metered and payments were instead based on its estimated annual heat use.

 Requirements for qualification are:

  • The property must have loft and cavity wall insulation if it is recommended in the Green Deal Advice Report,

    If it is not possible to do this, then you could submit evidence to us as part of your application.

  • The property must have valid planning and environmental permissions for the installation.
  • The biomass boiler must be certified under the Microgeneration Certification Scheme (Dunster boilers are MCS certified), which means that domestic RHI income can only be earned by boilers with a rating of up to 45 kW.
  • The installer must be MCS certified (Dunster is MCS certified).
