Optional Monitoring

There’s an optional Metering and Monitoring Service Package (MMSP) you may be able to register for as a participant in the Domestic Renewable Heat Incentive (RHI) scheme. The packages are available on a first-come, first-served basis. There are 11,255 MMSP packages available in total. We publish the data quarterly on our website.

What is MMSP?

An MMSP works like a service contract and is a useful way of checking how well your heating system is performing and whether or not it is performing to the level promised by your installer. People who are successful in registering an agreement for MMSP receive some financial support for installing the package and sticking to the agreement. The package will also provide comprehensive data which will inform future research on the performance of heat pumps and biomass pellet boilers.

An MMSP is different to installing meters to receive Domestic RHI tariff payments (‘metering for payment’) and metering for performance, which some people joining the scheme have to do. You can apply for MMSP registration at any point during the period of your participation in the RHI Scheme, including when you first apply to the scheme.

Who's it for?

It's only for those with heat pumps or biomass boilers that burn wood pellets only (not biomass pellet stoves or any other biomass boilers).

If you have a heat pump: You can apply for MMSP registration whether or not your heating system needs to be metered for payment or metered for performance . It doesn't affect your participation or payment criteria.

If you were accredited or applied on or after 22 May 2018 and you have a heat pump, you will be required to have electricity metering alongside your heating system. MMSP is one of the three electricity metering options available to meet that requirement – this is because registering for an MMSP requires you to agree to install “eligible electricity meters”, which is also one way to meet the new heat pump metering for performance requirement.

If you have a biomass pellet boiler: You can apply for MMSP registration whether or not your heating system needs to be metered for payment - it doesn't affect your joining or payment criteria.

An MMSP is useful if you are interested in analysing heating data to see how your system is performing. You may be able to log on to a website and view the data captured. It’ll help you check your system is working as efficiently as it should.

Your MMSP provider will also be able to see the data so they can help identify problems, or let you know if your system is underperforming.

How much extra would I get?

If you successfully registered for MMSP before 22 May 2018:

  1. £230 per year (£57.50 every three months) for heat pumps
  2. £200 per year (£50 every three months) for biomass pellet boilers

If you applied for the MMSP at the same time as your Domestic RHI application, you would get the maximum of seven years of MMSP payments. If you applied for the MMSP afterwards, you’d only get payments for the remainder of the seven years, or until the MMSP agreement ended or was terminated, or we withdraw your registration.  

If you successfully registered for MMSP on or after 22 May 2018:

New MMSP registrations on or after 22 May 2018 will be able to get a lump sum payment alongside their first Domestic RHI payment, and a maximum of up to seven years of annual MMSP payments.

  1. a single lump sum payment of £805, and MMSP payments of £115 per year (£28.75 every three months) for heat pumps
  2. a single lump sum payment of £700, and MMSP payments of £100 per year (£25.00 every three months) for biomass pellet boilers

If you applied for the MMSP at the same time as your Domestic RHI application, you would get the maximum of seven years of MMSP payments.

If you applied for the MMSP after your initial application to the Domestic RHI, you still get the lump sum payment, but only the remainder of annual MMSP payments of the seven years of your RHI lifetime, or until the MMSP agreement ended or was terminated or we withdraw your registration. We have worked with the Renewable Energy Consumer Code (RECC) to provide a model agreement, which can be found on the RECC website. Applicants must then submit the agreement to us as part of your MMSP registration application.

Your payments will be made until the end of your RHI lifetime, or until the MMSP agreement ends or is terminated, or your registration is withdrawn by us.
