When will the RHI be introduced?

The first phase of the RHI, which launched in November 2011, focuses on larger industrial and commercial, as well as public and community buildings.

The householder phase was originally due to launch in October 2012, when the government’s Green Deal plan kicks in. However, this has now been delayed, and the Department of Energy and Climate Change has yet to announce when the household phase will exactly launch.

In the meantime, in order to encourage take-up of renewable heat technologies, RHI Premium Payments are being made available. These are one-off payments to help homes cover the initial cost of getting a new renewable heating system installed. £25m has been set aside for this. See RHI savings and earnings for more details.

How will the RHI payments work?

After joining the RHI scheme, homes will receive a quarterly tariff payment for every kilowatt hour (kWh) of renewable heat they produce, measured using an installed heat meter, and payable for 20 years. Tariff levels for the household phase have not yet been set out but are likely to vary for different technologies. Energy regulator Ofgem will be responsible for dealing with applications and payments.

Biomass boilers burn wood chips or pellets and will qualify for the RHI

Which renewable heat technologies will be eligible?

  • Solar thermal heating systems
  • Biomass or woodburning boilers
  • Ground source heat pumps
  • Air source heat pumps

You can find out more about these technologies – including how to determine whether your home will be suitable to install any of them – in our dedicated guides: home heating systems, ground source heat pumps,solar panels and wood heating systems.

I already have a renewable heating system installed. Will I be eligible for the RHI?

Owners of all eligible renewable heating systems installed on or after 15 July 2009 will be able to apply for the RHI once it’s introduced. If your heating system was installed before this date, you will not be eligible for RHI payments.

Is the RHI different from the feed-in tariff?

The RHI is similar to the feed-in tariff (FIT) scheme, but supports different types of renewable technology.

The FIT pays households and communities that generate their own electricity from renewable sources such as solar electricity (PV) panels or wind turbines, while the RHI is designed specifically for technologies that heat buildings. FIT pays households for excess electricity exported out to the National Grid.

Because heat can’t be sold to other users, the RHI is unlikely to include an equivalent to the export tariff element that’s available with the FIT.
