## Summary

The London Borough of Southwark seeks one service provider for quality auditing across its housing stock. The work covers gas-servicing systems and processes, individual boiler installations, leaseholder gas-servicing records and certification, district-heating plants, boiler rooms and energy centres. The provider will audit inspections, certification and maintenance records, Legionella risk assessments and testing regimes for cold-water services and associated plant, as well as internal systems for compliance with legislation, regulations and industry standards. It will also carry out work-in-progress quality-control audits to check installation quality and compliance with specifications, and manage related documentation through the Southwark Portal. This is a technical inspection, testing and engineering consultancy service, delivered for council housing in Southwark, London.

The procurement has reached tender: the council invited offers through a selective restricted procedure, with electronic submission in English. The tender submission deadline set by the buyer is 9 October 2026. The contract is scheduled to run from 2 February 2027 to 1 February 2030, with an option for renewal. The estimated value is £1.3 million including the single lot. Bidders may not submit variants. The requirement is covered by the Government Procurement Agreement. The successful provider will be appointed for the full scope as one lot, rather than bidding for separate service packages. Further information about submission through the relevant dynamic purchasing system service is provided at the stated procurement web address.

This opportunity suits an established technical auditing, inspection or compliance consultancy able to cover domestic gas servicing, boiler installations, district heating and energy-centre plant within one service. Relevant capability includes reviewing statutory records and certification, checking maintenance and inspection regimes, assessing Legionella controls for cold-water systems, and testing whether internal procedures meet current legislation, regulations and industry standards. The provider must also be able to perform site-based work-in-progress quality checks against installation specifications and produce controlled audit documentation. A supplier should have the capacity to manage a broad council housing programme through a single service team, handle records and evidence systematically, and use the Southwark Portal for document management. Experience across housing mechanical services and building-services compliance will be directly relevant.
