Summary of the contracting process

The National Gallery commissioned refurbishment and environmental-control works for galleries 30 and 31 at its Trafalgar Square site in London. The works category covers roof works and refurbishment (CPV 45260000 and 45453100). The scope includes structural alterations and a new external over-roof with glazing, solar-control blinds, guarding, gantries, roof finishes, louvres, flashings and membranes. It also includes external wall insulation, waterproofing and leak detection, air conditioning and associated mechanical, electrical and plumbing systems integrated with the existing building-management system. The contractor is responsible for gallery wall, floor and ceiling finishes, gilding to ornate ceiling plasterwork, repairs to retained internal finishes, and an external steel gantry for plant relocation, access and maintenance.

This procurement has reached award stage: CBRE Managed Services was selected for the single lot, with award dated 10 September 2026. The award is pending, with standstill ending on 22 September 2026 and a scheduled contract signature by 28 September 2026. The awarded value is £5,205,000 excluding VAT and £6,246,000 including VAT. The award contract period is 29 September 2026 to 30 September 2027. The earlier estimated value was £5,200,000 excluding VAT and £6,240,000 including VAT. It used a selective competitive flexible procedure, with a procurement-specific questionnaire shortlisting five to six suppliers. Four valid final bids were received. The expression-of-interest deadline was 23 March 2026 at 12:00 UTC, and the award-period end date was 1 June 2026. Evaluation ranked technical quality first, price second and social value third. Economic and technical selection criteria were set out in the procurement-specific questionnaire. Additional refurbishment to an adjacent gallery could be commissioned subject to funding and programme.

This award demonstrates demand from a major London cultural institution for a principal contractor able to deliver complex refurbishment in operational or sensitive gallery environments. Credible competitors would need coordinated capability across structural steelwork, specialist roofing and glazing, solar control, insulation, waterproofing, leak detection, air conditioning, mechanical and electrical services, building-management-system integration and high-quality internal finishes. Experience protecting and repairing retained historic or ornate finishes, including gilding, would be relevant, as would the ability to design, install and maintain access and plant gantries. The requirement suits established building contractors able to manage multiple specialist trades, commissioning and interfaces as one programme. Social value formed part of the evaluation, while three of the four final-stage bidders were SMEs, indicating that smaller firms may be competitive where they can demonstrate sufficient delivery capacity and specialist supply-chain management.
