RHI: Domestic

The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. By switching your home to our biomass heating systems you can get considerable payments allowing you to not only save your money but also the environment.

Eligibility

You are eligible for the scheme if you are looking to heat a single property by a renewable heating system such as biomass.
Dunster can help to advise customers on the RHI scheme and eligibility criteria; we can also assist clients in their registration.

Green Deal Assessment

A Green Deal Assessment analyses your property's home energy requirements. To be eligible for the Domestic RHI scheme you will need this assessment.

Be ready to be assessed and download a Green Deal Assessment Checklist.

Energy Performance Certificate (EPC)

After you have completed a Green Deal Assessment, you will need an EPC. The EPC is the proof we need that your property is assessed as a domestic ‘dwelling’.

Payments

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: Current tariff levels

Tariff levels have been set at 5.14p/kWh for biomass boilers.

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 EPC. This is divided by four for a quarterly figure.

Example
35,000kWh (estimated annual heat load) x 5.14p/kWh
= £1,799 /4
£449.75 per quarter

Metered biomass systems

Metered biomass systems are sometimes necessary for various reasons such as having a fossil fuel backup boiler installed on the same system. In this case 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.

Requirements for qualificationFroling boiler

  • 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).
