Summary of the contracting process

The National Gallery appointed a sustainability consultant for a new wing integrated with its existing estate at Trafalgar Square, London. The work is environmental engineering consultancy supporting a new building in a constrained and sensitive urban, cultural and heritage setting. The consultant leads and coordinates the sustainability strategy across the project, covering operational energy, embodied carbon, Whole Life Carbon, circular economy principles, environmental performance and planning-policy compliance. Services also cover demolition, retention, retrofit and adaptation of existing buildings; planning and statutory approvals; environmental certification, including BREEAM; and coordination with architectural, engineering, planning and cost-management disciplines. The role extends through design, procurement, construction, handover and operation, including sustainability advice and integration with the existing National Gallery estate and heritage context.

The procurement is complete at award stage, with Building Design Partnership Limited selected for the single lot. The award was dated 30 July 2026 and is subject to a standstill ending 11 August 2026. The awarded value is £198,650 excluding VAT (£238,380 including VAT), with the award period running from 12 August 2026 to 31 March 2032. The estimated lot value was £200,000 excluding VAT (£240,000 including VAT). This was an above-threshold open competitive flexible procedure. Fourteen bids were received and 12 reached the final stage. Evaluation weighted the sustainability strategy and technical approach at 25%, commercial proposal at 30%, proposed team at 15%, project understanding and key sustainability challenges at 10%, delivery management and team integration at 10%, and social value at 10%.

This requirement demonstrates demand from a major cultural institution for senior sustainability consultancy across a complex capital project and an existing heritage estate. A credible competitor would need a team able to lead sustainability strategy while coordinating effectively with architects, structural, mechanical, electrical and public-health engineers, planners, cost consultants and other disciplines. Relevant capability includes operational-energy, embodied-carbon and Whole Life Carbon assessment; circular-economy advice; demolition, retention, retrofit and adaptation strategies; planning-policy compliance; Circular Economy Statements; BREEAM and other environmental certification; and advice in constrained, sensitive and heritage environments. Experience supporting projects from design through construction, handover and operation would be important, alongside sufficient financial capacity, insurance, legal standing and project-specific technical capability to pass participation requirements.
