The Government has introduced changes to the Domestic RHI Regulations. Changes were introduced in two stages. The first stage of changes to the Domestic Scheme came into effect on 20 September 2017. The second stage came into effect on 22 May 2018.
For more information about changes to the scheme and what they mean to you, please see our changes to the scheme webpage and our Factsheet: Important changes to the Domestic RHI Scheme.
A Metering and Monitoring Service Package (MMSP) is similar to a service contract and is a useful way of checking how well your heating system is performing. People who are successful in registering an MMSP receive financial support for installing the package. The package will also provide comprehensive data which will inform future research on the performance of heat pumps. MMSP is only available for heat pumps, or biomass boilers that burn wood pellets (not biomass pellet stoves or any other biomass boilers).
The MMSP consists of high specification heat meters, electricity meters and temperature sensors installed on the heating system. It will log data at least every two minutes, and your installer will be able to see the data. If your application and MMSP agreement meet the requirements, we will pay you the applicable MMSP amount along with your quarterly tariff payments to help cover some of the costs of the MMSP installation.
As well as entitling you to separate payments, an MMSP typically meets requirements when you are ‘Metering for Payment’. Additional meters would not need to be installed to calculate quarterly Domestic RHI payments.
You can apply for MMSP payments at any point throughout the duration of your accreditation to the RHI scheme. This means you can also apply at the same time as you apply to Domestic RHI, but your MMSP can only be registered if and when your heating system is accredited. If your membership with the Domestic RHI is terminated, your MMSP registration will also end.
See below for a payment example for a heat pump:
|Applicant successfully registers at the same time as domestic plant accreditation||£805 + (£115 x 7 years) = £1,610|
|Applicant successfully registers in the last year of their Domestic RHI membership||£805 + (£115 x 1 year) = £920|
See below for a pellet biomass boiler calculation example:
|Applicant successfully registers at the same time as domestic plant accreditation||£700 + (£100 x 7 years) = £1,400|
|Applicant successfully registers in the last year of their Domestic RHI membership||£700 + (£100 x 1 year) = £800|
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.
