MCS data highlights upward trend for renewables


16 February 2023

New data from MCS (Microgeneration Certification Scheme) reveals a significant increase in demand for heat pumps in the UK, with more than 30,000 certified installations in 2022.

March last year saw the largest spike in heat pump installations of any month in MCS history, as customers accessed the Domestic Renewable Heat Incentive scheme before its closure. Heat pumps are the second most popular technology type behind solar PV and accounted for 19% of total renewable installations last year. 

Heat pump uptake remained high following the launch of the government’s Boiler Upgrade Scheme (BUS), which launched in May 2022 to encourage households across England and Wales to access a £5,000 or £6,000 grant to replace their boiler with a more environmentally friendly heating system. During 2022, almost 9,000 BUS vouchers were issued with a value of nearly £45 million. Under the scheme, the government aims to fund 90,000 heat pumps by 2025.

Overall in 2022, a total of 163,341 MCS-certified installations were registered, over 80% of which were electricity generating technologies – mainly solar PV. This marks the highest annual deployment since 2015, when just over 200,000 installations were registered.

There was substantial growth of solar PV installations in 2022, more than doubling those seen in 2021. With 130,596 solar PV installations throughout the year, there was an overall increase of 114% when compared to the number of installations in the previous year.

Battery storage is a newcomer in the registered installations for 2022, with the first MCS certified battery storage installation being registered in April 2022. Since then, battery storage has seen a steady growth, finishing the year with 50 certified contractors and 269 installations – this was up from only two contractors registered in 2021.

In total, 780 new contractors became MCS certified in 2022 which is more than double the net increase from 2020 to 2021. This makes 2022 the highest annual increase of certified contractors in over a decade. Of these new contractors, 67% are certified for electricity generating technologies, evidencing further the increasing appetite for solar PV on UK homes.  

As MCS certification is not a mandatory requirement, the MCS Installations Database (MID) does not capture every renewable installation in the UK. However, as MCS is the route to incentive, they are confident their installation data represents the majority of systems installed since the late 2000s.

Ian Rippin, CEO of MCS, said: “We're pleased to report our second strongest year since 2015, illustrating the sector’s upward trajectory. We had an incredibly busy 2022 and the data confirms the progress we’ve made. The future of small-scale renewable installations is becoming increasingly important, and we continue to play a crucial role in the decarbonisation of the UK's homes.

“The growth we’ve seen in domestic renewable electricity systems over the past year may also give some insight into the growing consumer reliance on home-grown energy in the UK during the cost-of-living crisis. As electricity prices skyrocket, more people are turning to renewable solutions to generate their own power at home.

“Looking ahead, we need to drive this momentum and upward mobility at pace and continue to ensure consumer confidence across all technology types. To support this and ensure government targets are met, more skilled contractors are needed. As such, we will launch the Low Carbon Heating Technician Apprenticeship later this year. We are confident this will attract young people and career-changers to the industry, creating a more diverse workforce that meets the demands of the industry while providing future-proof careers in the green sector.”

Since MCS began recording installations, the scheme has seen more than 1.5 million certified systems go into UK homes. This was achieved by the ever-growing MCS contractor base, which now includes more than 3,000 certified businesses.
