What is the Welsh government doing?

Page updated on: 23/09/2024

By 2025 around 148,000 houses across Wales will receive retrofit measures to reduce heat loss.

Wales has homes of every size and type, many of which are older buildings. We also have a slightly higher proportion of solid-wall homes compared to the rest of the UK, which means our houses can be more expensive to insulate. There’s no one-size-fits all approach; each property needs to be individually evaluated to find the right insulation solution. This is why the Welsh Government is working on a number of policies to help us all retrofit energy efficient measures in our homes, beginning with social housing.  

The Welsh Government is helping to insulate homes, working with local authorities and social landlords as part of the Optimised RetroFit Project. Already in phase three and with £60m committed between 2022 and 2023, it’s designed to make social housing more energy efficient. The aim is to have installed energy saving measures to reduce heat loss in 148,000 homes across Wales by 2025.  

The Warm Homes Nest scheme also provides free energy efficiency advice and offers a package of free energy efficiency improvements to households worried about energy bills.  

By 2025 the government aims to increase the proportion of electric heat by 3% to reduce the use of fossil fuels. It also aims to meet 100% of its electricity needs from renewable sources by 2035.

By 2025 all new affordable homes in Wales will be built to net zero carbon, and the ambition is that these standards are adopted by developers of all new homes.

A new state-owned energy developer will build wind farms to produce power that directly benefits people in Wales.
