Wales and Scotland continue to battle for the top spot when it comes to renewable uptake, but MCS data shows there has been a total of 117,804 installations in Wales since records began in 2008, accounting for 8.74% of households with a renewable installation. 

This puts it ahead of Scotland’s 8.47%, leaving England and Northern Ireland further behind with uptake of 5.86% and 4.41% respectively. 
 
January to March 2024 saw Wales achieve its best-ever start to a year for heat pumps. A total of 1,947 heat pumps were installed in Wales within the first three months of 2024, averaging 650 a month. 

This marks an 80% increase from 2023 when Wales averaged 361 heat pumps per month during the same period. 

Ceredigion is the local authority in Wales with the highest uptake for renewable energy, with nearly one in four households now benefitting from an MCS-certified installation. The Isle of Anglesey is in second place with over 1 in 5 households having renewable energy installation.  
 
Welsh Local Authority Leaderboard:   
1.    Ceredigion – 23.47% uptake 
2.    Isle of Anglesey – 20.91% uptake 
3.    Powys – 18.79% uptake 
4.    Pembrokeshire – 16.5% uptake 
5.    Monmouthshire – 14.26% uptake 
 
The success of renewable energy and heating installations in Wales is driven by the grants and incentives available. 

The ECO Grants Scheme, a UK Government incentive scheme, offers free renewable energy installations like heat pumps and solar panels to low-income households, to help make their homes more energy efficient and save on energy bills.
 
One Welsh MCS-certified contractor installing renewables under ECO4 is Anglesey-based Menai Heating Limited. Its director, Lee Maher, believes ECO4 is vital to powering forward Wales’ renewable uptake.  
 
He said: “Since the start of 2024, we’ve delivered over 220 MCS-certified renewable installations across Wales under the ECO4 scheme. Through ECO4 we’re able to upgrade poorly insulated homes and support low-income households with solar panels, heat pumps, and various other energy-saving measures – all without any cost to the homeowner.”
