## Summary

PROSPER has established the Decarbonisation & Investment Works Framework, a multi-supplier framework aimed at providing energy efficiency retrofit measures and refurbishments across domestic and public buildings in the UK. This framework, divided into ten regional lots including areas such as North East and London, seeks up to ten principal contractors per lot. The procurement process, using an open procedure, has completed the award stage as of 20th June 2025, with the contract period extending from 23rd June 2025 to 22nd June 2029. The focus industry is electricity, heating, solar, and nuclear energy, encompassing a range of services such as roofing and building installations.

This framework presents significant opportunities for businesses specialising in construction works, architectural services, and energy solutions to expand their market presence. Small and medium-sized enterprises (SMEs) are considered suitable, offering them a chance to enhance growth through collaboration within the public sector. Companies with expertise in retrofitting energy-efficient solutions and traditional building refurbishments will find this an advantageous contract to pursue. The diverse requirements and extensive geographical coverage offer varied prospects for established players and burgeoning enterprises alike, particularly those adept in PAS 2035 consultancy and building completion work.
