## Summary

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.

Works will include maintaining domestic gas installations in a full, efficient and safe working condition, and carrying out all necessary servicing and repairs as defined within the framework specification to approx. 11,500 properties. The works shall include the replacement of all parts as necessary to ensure the safe and efficient operation of all domestic gas system to the residential premises. It is also proposed the contractor will also have the capability to support service provision in the south of the borough (Lot 2) during periods of high demand or reduced performance. Lot 2: Domestic Gas Boiler Responsive Repairs and Servicing - South The council proposes appointing a single contractor to a framework to deliver domestic gas repairs and servicing in the south of the borough, based on the "3 Star Contract" approach. The council's inhouse team does not currently operate in this area of the borough. Works will include maintaining domestic gas installations in a full, efficient and safe working condition, and carrying out all necessary servicing and repairs as defined within the framework specification to approx. 11,500 properties.

Lot 3: Domestic Planned and Reactive Gas Boiler Installations - Borough-Wide The council proposes appointing two contractors to deliver borough-wide domestic gas boiler installations both planned and reactive and provide an out of hours response service to approx. 23,000 properties. The in-house team does not do any boiler installation work. It is proposed call-off contracts for works orders are issued to contractors in Lot 3 in rotation and will be monitored closely by the Council using its IT systems.
