Installers and metering

The Government introduced new regulations on 20 September 2017. For information on what the Government changes mean for you, please see our changes to the scheme webpage.

In March 2016, the Government published a consultation on changes to the Domestic Renewable Heat Incentive (RHI) scheme. After taking account of the feedback it received, the Department for Business, Energy & Industrial Strategy (BEIS) published its consultation response on 14 December 2016. Subject to Parliamentary approval, it’s planned for these changes to be introduced in two stages.

The first stage of changes came into effect on 20 September 2017. You can read the amending regulations here.

Subject to Parliamentary approval, it’s planned for the second stage of regulation amendments to follow later in 2017/2018. When the second stage of planned changes come into effect later in 2017/2018, all new accreditation applications for heat pumps to the Domestic RHI scheme will be required to have electricity metering arrangements installed alongside their heating system.

Please note that the content and timing of any changes we outline will be subject to parliamentary process. Our updates are based on information provided by the Department for Business, Energy & Industrial Strategy (BEIS).

As an installer you need to know when, under the Domestic RHI scheme, a system must be metered for payment* and/or when a system must be metered for performance*, how these types of metering work, and what metering documents you have to complete and give to your customer for their application.

Solar thermal for heating domestic hot water never has to be metered. If that’s all your customer has installed, you don’t need to read this page.

Where systems need to be metered for payment

Below we’ve highlighted some common situations which do require metering for payment, but for full details make sure you read our Essential Guide to Metering.

1. Where there’s back-up heating

This applies where:

  • The renewable heating system is installed alongside a fossil fuel space heating system. For example, where there’s a biomass boiler and a back-up oil boiler;
  • The renewable technology is a heat pump with an integrated fossil fuel system, like a gas boiler, built into it; and/or,
  • There’s more than one renewable heating technology for space heating, for example, where there are two biomass boilers. See multiple products (open key pop up term) for more information. (Remember that it’s fine to have a solar thermal plant installed alongside your other technology, as long as it’s only heating domestic hot water).

Back-up heating that doesn’t count: The system doesn’t need metering if the back-up heating is only designed and installed to heat a single room, such as an open fire or plug-in electric heater. Similarly, immersion heaters and supplementary electric heaters, that some heat pumps and biomass systems have, don’t count. Heat recovery systems that recycle air but don’t generate additional heat also don’t need to be metered.

2. Where there’s a biomass heating system that isn’t designed to heat the whole property

Biomass systems must meet all of the space heating requirements for the property. Anything less means the system will need to be metered.

3. Where the property is occupied for less than half the year

Homes that have been lived in for less than half the year must be metered. This includes second homes or tenanted properties, which have been empty for 183 days in the 12 months prior to applying to the scheme, or any time after accreditation onto the Domestic RHI.The applicant needs to declare on the application form if their home is occupied for less than 183 days a year. This rule doesn’t apply if the applicant is applying as a custom build.

Where systems need to be metered for performance

This section only applies if your customer has a heat pump.

When the second stage of changes from the Government’s 2016 consultation response comes into effect, planned for later in 2017/2018, it will be a requirement that all new applications for air source and ground source heat pumps must have electricity metering arrangements alongside their heating systems to be eligible for the Domestic Renewable Heat Incentive (RHI).

There are three metering arrangement options available for metering for performance:

  1. Stand-alone electricity metering*
  2. On-board electricity metering*
  3. Metering and Monitoring Service Package (MMSP)
