Summary of the contracting process

The London Borough of Southwark is embarking on a procurement process to carry out decarbonisation works at The Castle Leisure Centre in central London, as part of a major initiative to support climate commitments and improve energy efficiency. The procurement process is currently at the planning stage, with the tender set to be conducted using a single-stage limited competition method, specifically targeting below-threshold contracts. The planned contract period is from 23rd July 2026 to 31st May 2027, and the project is anticipated to be highly beneficial for the construction industry, focusing on steam, hot water, solar energy, and heat pump installations. The procurement is supported by Phase 4 funding from the Public Sector Decarbonisation Scheme, with the design completed to RIBA Stage 4.

This procurement presents significant opportunities for construction companies, particularly those adept at energy efficiency and sustainable projects, to expand their portfolio by undertaking work funded by the Public Sector Decarbonisation Scheme. Small and medium enterprises (SMEs) are well-suited to compete, especially those listed on the Alcumus SafeContractor, a directory of construction companies approved for work for the London Borough of Southwark. Investing in innovative decarbonisation technologies can position businesses for future growth in the evolving area of renewable energy and sustainable construction, offering a promising avenue for market engagement and collaboration with public authorities.
