Non-Domestic RHI


Ofgem is responsible for implementing and administering the scheme on behalf of the Department of Energy and Climate Change.

The objective of the Non-Domestic RHI is to significantly increase the proportion of heat generated from renewable sources.  By driving change in a heat sector currently dominated by fossil fuel technologies, the RHI can help the UK meet EU targets to reduce carbon emissions and improve energy security. In addition the Non-Domestic RHI has the wider potential of developing ‘green jobs’.

The Non-Domestic RHI is open to the non-domestic sector including industrial, commercial, public sector and not-for-profit organisations with eligible installations. In the context of the scheme, a non-domestic installation is a renewable heat unit that supplies large-scale industrial heating to small community heating projects.

This includes for example small businesses, hospitals and schools as well as district heating schemes such as where one boiler serves multiple homes.  All applications are subject to the detailed scheme rules.

Ofgem are responsible for publishing quarterly tariff tables showing the tariffs that will be applicable for each tariff period, take a look for the latest rates.

Domestic RHI

The key to joining the Domestic RHI is that the renewable heating system heats only a single property which is capable of getting a domestic Energy Performance Certificate (EPC) open key term pop-up. 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.

Boiler Upgrade Scheme

The Clean Heat Grant, now known as the Boiler Upgrade Scheme (BUS), is a government scheme due to launch in spring 2022 that will help to fund a transition from gas boilers to low-carbon alternatives such as air source heat pumps, ground source heat pumps and biomass boilers, homeowners will receive £5,000 towards the installing an air source heat pump, and £6,000 towards a ground source heat pump. Homeowners in rural areas could receive £5,000 towards the cost of a biomass boiler.

It is designed to replace the Domestic Renewable Heat Incentive (RHI), which will close to new applicants on 31 March 2022. The RHI scheme offered tariff payments for a period of seven years, rather than an upfront payment.
