Domestic RHI

Financial support for homeowners installing renewable heating systems.

Ofgem is the Office of Gas and Electricity Markets which is the non-ministerial government department and independent National Regulatory Authority that administer the UK RHI scheme.

What is the Domestic RHI?

The Renewable Heat Incentive, or RHI, is the government scheme to encourage the shift to low carbon and renewable heat technologies.

If your installation is eligible for the scheme, you will receive quarterly payments for seven years for the amount of clean, green renewable heat the system produces. This can be as much as £12,000 over the 7 year period.

The domestic RHI has been designed as a ‘boiler replacement scheme’. As such, the payments are intended to bridge the costs between the installation and running costs of fossil fuel heating systems and the renewable alternatives.

How much are the payments?

Homeowners are paid per kWh of renewable heat generated, for seven years. The amount of heat generated from your installation will be ‘deemed’. This is an estimate of the property’s expected annual heat usage (to avoid the cost of metering). You multiply the deemed heat load of renewable heat by the tariff rate to calculate the annual payments.

The tariff for applications made up to 31st March 2021 is 6.97p/kWh.

Once your RHI application is accepted, you are guaranteed that rate, plus inflation, for the next 7 years.

For biomass the estimated heat use of a property will be taken from the energy performance certificate (EPC).

When are payments made?

Payments will be quarterly, in arrears, by Ofgem. Payments will change annually in line with the Consumer Prices Index (CPI). While paid over a seven year period, the rates have been calculated over the expected 20 year life of the systems.

Is the RHI index-linked?

Yes, tariffs will change annually in line with the Consumer Prices Index (CPI). Changes will come into effect on 1 April each year. Prior to 1st April 2016 the tariffs changed according to the Retail Prices Index (RPI).

When will rates change?

A degression scheme has been put in place to manage the RHI budget. This means that tariff levels for new applicants will decrease by 10 or 20 per cent once specified amounts of the budget have been spent. The government will check every quarter to see if triggers are met. If they are, a month’s notice of the tariff reduction will be given. Degression will be per technology, not for the scheme over all, so that one technology is not allowed to dominate the budget. The government reserves the right to hold a review of the scheme at any time.

RHI Scheme Requirements

The key to applying to the Domestic RHI is that your renewable heating system must be for a single home in a property that can get a domestic Energy Performance Certificate (EPC).

All heating systems and installers must be accredited by MCS or an equivalent scheme. In addition, installers must be members of the Renewable Energy Consumer Code (RECC).

Full details of requirements can be found on Ofgem’s website.

Eligibility Criteria

A full checklist of eligibility requirements is available from Ofgem. In summary your biomass heating system must:

  • use eligible boilers
  • be MCS certified
  • provide space heating

You also need an Energy Performance Certificate (EPC) for your home and have to apply within 12 months of your boiler being commissioned.
