With decarbonisation a key strategic goal for local authorities and social housing sectors, R&M Williams is your ideal partner for retrofit measures to decarbonise existing stock in response to climate change, making homes and buildings more energy efficient and cheaper to run for residents and occupants.

We are accredited for all measures under PAS2030:2023 & PAS2035. In February 2025 we were appointed to the Welsh Procurement Alliance (WPA) Retrofit and Decarbonisation (N9) Framework. The framework supports local authorities, housing associations, education and other public sector organisations in delivering a range of energy efficiency and decarbonisation works, helping them with the challenge of achieving net zero and improving the EPC ratings of their stock.

We were successful on all multi-disciplinary lots and specialist measures lots, including EWI, Solar PV, and Loft Insulation. The new framework is the successor to the Energy Efficiency Measures & Associated works (N8) framework.
