Optional monitoring

Mae’r dudalen yma ar gael yn Gymraeg.

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.

There is an optional Metering and Monitoring Service Package (MMSP) that you can register for in the Domestic Renewable Heat Incentive (RHI).

What is optional monitoring?

An MMSP works like a service contract and is a useful way of checking how well your heating system is performing. People who are successful in registering for MMSP get paid extra per year towards its costs.

It's completely different to installing meters to receive Domestic RHI tariff payments, which some people joining have to do.

Who's it for?

It's only for those with heat pumps or biomass boilers that burn wood pellets (not biomass pellet stoves or any other biomass boilers). You can register for it whether or not your heating system needs to be metered for payments and it doesn't affect your joining or payment criteria.

It's useful for people interested in analysing their heating data to see how their system is performing. You'll be able to log on to a website and view the data captured. It’ll help you check that your system is working as efficiently as it should.

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

How much extra would I get?

If you have a heat pump you get an extra £230 per year (£57.50 per quarter) and for a pellet biomass boiler an extra £200 per year (£50 per quarter) until your payments stop. If you applied for the MMSP alongside your Domestic RHI application, you would get the maximum of seven years of payments. If you applied for the MMSP afterwards, you’d only get payments for the remainder of the seven years.

There is a budget limit which allows only a certain number of MMSP registrations. This is around 10,000 in total, available on a first come first served basis.

I’m interested and would like to find out more
