## Summary

PROSPER, acting as a central purchasing body, has facilitated a substantial procurement process titled "Decarbonisation & Investment Works Framework". This framework encompasses extensive building installation work, specifically targeting energy efficiency retrofit measures and traditional investment and refurbishment projects for domestic and public buildings. It involves multiple regions across the United Kingdom, including North East, Yorkshire & Humber, North West, West Midlands, East Midlands, East of England, South East, South West, London, and Wales. The procurement process is divided into ten lots, each aligned with a region, and follows an open procedure. Each lot seeks to appoint up to ten suppliers, with contracts signed on 20 June 2025, and the framework is set up to last for 48 months. The primary industry category is building installation work, with the project's total estimated value reaching £1 billion across all lots.

This procurement framework offers significant opportunities for contractors specializing in energy efficiency and refurbishment works. Small and medium enterprises (SMEs), along with larger companies, can leverage this framework to expand their business by competing in one or multiple regions. The framework prioritizes quality over price, with a quality ratio of 60% to 40%. Given the emphasis on energy efficiency and support for the Carbon Reduction and Net Zero Agenda, businesses with expertise in sustainable building practices and innovative solutions will be particularly well-suited to compete. By securing a position within one of the regional lots, suppliers can increase their visibility and credibility within the public sector market, fostering business growth and long-term partnerships.
