Summary of the contracting process

Salix Finance Ltd procured audit and inspection services for decarbonisation works across the UK. The scope covers primarily energy-efficiency consultancy, building-fabric and building-services consultancy, building inspections and auditing. Audits are required both during the delivery cycle and after decarbonisation works have been completed. The requirement is intended to provide independent technical assurance over works supported through Salix programmes, including checking their quality and completion. The service covers work in locations represented across England, Wales, Scotland and Northern Ireland, so suppliers need to support a nationally distributed programme rather than a single site or locality. This is a professional services opportunity for organisations combining energy, building-performance and audit expertise.

The procurement is complete and three separate contracts were awarded on 16 April 2026: AtkinsRéalis PPS Ltd, Ricardo-AEA Ltd and Arcadis Consulting (UK) Ltd each received an equal share of up to 33.33%. Each award and contract is valued at £233,333.33 excluding VAT (£280,000 including VAT). The contracts were signed on 18 May 2026 for Ricardo-AEA and Arcadis, and 8 July 2026 for AtkinsRéalis. Their periods run for two years, with two optional 12-month extensions, giving a possible 2+1+1 structure. It used an open competitive flexible procedure with two stages. Thirteen bids were received, six reached the final stage, and evaluation used quality and a Price per Quality point methodology, subject to a minimum quality score of 60/100. Selection also required mandatory economic, financial and technical standards.

This award shows sustained demand from Salix Finance for technically rigorous, nationally deployable audits of decarbonisation works. A credible future competitor would need qualified technical staff able to assess energy-efficiency measures, building fabric and building services, inspect completed works and produce defensible audit findings during and after delivery. The successful model relied on several suppliers with full national coverage, so organisations need enough geographically distributed resource and operational capacity to absorb fluctuating work across multiple regions without delaying audits. Strong quality assurance, budget management and client-list maintenance are central performance expectations. Suppliers should also be able to submit clear quality evidence alongside role-based hourly rates and meet Salix’s mandatory financial and technical requirements.
