Summary of the contracting process

Flagship Housing Limited established a Dynamic Purchasing System for energy-efficiency retrofit work and related consultancy for its group of subsidiary companies. The requirement covers the East of England. Installation work includes insulation, external wall insulation, roofing and roof insulation, heating, ventilation and air-conditioning, heat pumps, solar panels and photovoltaic systems, electrical installations, windows and doors, building completion, environmental improvements, and associated repair and maintenance. The consultancy lot covers energy-efficiency advice, architectural and engineering services, building surveys, heating-system design, building services and construction-related consultancy. This is housing retrofit work, combining practical installation capability with technical and surveying expertise. Mini-competitions are issued to suppliers registered on the system who have passed the selection stage.

The procurement has been awarded and the tender is complete. It used a selective restricted procedure to establish a Dynamic Purchasing System, with electronic ordering and electronic payment available. Both original lots—retrofit installation contractors and retrofit installation consultants—are recorded as cancelled. Under the installation lot, active awards cover External Wall Insulation to Cornerstone (East Anglia) Limited, with a contract value of £31.43 signed on 17 October 2025, and External Wall Insulation 2026 to Warmpro Insulation Specialists Ltd, valued at £236,637 and signed on 10 July 2026. The installation lot was planned for 1,800 days. Price was not the only award criterion; all criteria were set out in the procurement documents. Seven and ten bids were recorded for the installation lot.

This procurement demonstrates demand from Flagship Housing for external wall insulation and wider energy-efficiency retrofit across housing in the East of England. Suppliers well placed for comparable work include SME installation contractors able to deliver external wall insulation at property scale, coordinate building-completion activities and work within housing programmes. Relevant capability also includes thermal insulation, roofing interfaces, heating and ventilation, heat pumps, solar and photovoltaic systems, electrical work, windows and doors, and associated maintenance. Technical firms could compete through energy-efficiency consultancy, building surveying, architectural and engineering advice, heating-system design and construction-related services. A credible future supplier would need to show practical delivery capacity, technical competence and the ability to participate in repeated mini-competitions through a Dynamic Purchasing System.
