## Summary

The procurement process led by Stonewater Limited has concluded with the award of a contract for the "00350-AST Whole House Retrofit Installation Works 2026-2030." This project aims to implement energy-efficient retrofits, contributing to the Net Zero Investment Plan. The tender, divided into four geographical lots, involves works such as insulation, heating systems, and solar PV installations, with the total estimated contract value of £62.2 million. The open procedure, categorized under works, is split across the United Kingdom, specifically in the West, South East, South West, and East regions. The process reached the award stage with key dates, including the contract's start date on 10th August 2026 and a completion by 9th August 2030, with potential renewals extending to 2032.

This tender represents a significant opportunity for businesses involved in refurbishment and energy efficiency sectors to secure substantial work, generating business growth. The open procedure allowed large-scale contractors, such as Wates Property Services Ltd, Equans Regeneration Limited, and Sureserve Energy Services, to secure their positions as suppliers for this substantial project. The project's division into regional lots ensures that businesses with local expertise and the capabilities for self-delivery of retrofit components could effectively compete. This framework offers potential for scaled growth over time, particularly for firms that can adapt to increased service demands in line with Stonewater's potential expansion of its housing stock during the contract term.
