Summary of the contracting process

The London Borough of Islington is planning a procurement process for domestic gas boiler installations, servicing, and repairs. This process is currently in the planning stage, aiming to establish a framework with multiple lots to manage gas installations and maintenance in the borough. The industry category is construction, focusing on heating systems and equipment, with services expected to cover approximately 23,000 residential properties. Key dates include the deadline for expressing interest in the upcoming tender by 11th May 2026, with the procurement activity scheduled to commence on 1st June 2027 and running through to 31st May 2030, potentially extending to June 2032. Located in London, this initiative by Islington Council targets effective management and safety of domestic gas systems within its housing stock, enhancing competition and transparency in the sector.

This tender presents significant opportunities for businesses in the construction and maintenance sectors, specifically those specialising in heating, ventilation, and air-conditioning systems. With plans to establish a framework agreement for responsive repairs, servicing, and installations, businesses with capabilities in these areas can benefit from a consistent flow of work. The opportunity favours SMEs, potentially fostering growth and expansion for smaller firms eager to enter the public procurement market. Contractors capable of providing out-of-hours emergency support, efficient maintenance, and installation services will find themselves particularly well-suited to compete, as the council aims to maintain high standards of safety and operational efficiency across its properties. The procurement method involves a planned framework agreement, fostering a robust partnership between the council and qualified suppliers to ensure reliable service delivery.
