## Summary

The Department for Energy Security & Net Zero commissioned services to facilitate and fund the participation of a UK expert in reviewing Luxembourg’s Biennial Transparency Report under the United Nations Framework Convention on Climate Change. The wider requirement covers UK experts reviewing Biennial Transparency Reports submitted by other countries. The work is classified as research services. Participation is restricted to UK experts who are members of the UNFCCC Roster of Experts. The buyer is a UK central government department based in London. The requirement therefore suits organisations able to identify, support and fund suitably qualified UK climate or emissions-reporting experts for international UNFCCC review assignments, rather than general research providers without access to the relevant expert roster.

The procurement has been completed and the contract was awarded to WSP UK LTD. It used a direct award below the applicable threshold, without competition. The award was made on 1 September 2026 and the contract was signed on the same date. The contract runs from 4 September 2026 to 13 November 2026. Its value is £20,228.90 excluding VAT, or £24,274.68 including VAT. There was one completed lot covering the review assignment. The selected supplier is WSP UK LTD, and the award remains active. The requirement was evaluated through the direct, non-competitive route rather than an open tender, so the outcome provides a clear example of the buyer’s approach to a small, specialist international reporting review requirement.

This award indicates demand for specialist support connected with UNFCCC Biennial Transparency Report reviews, including the practical facilitation and funding of UK expert participation. A credible competitor would need established access to UK experts on the UNFCCC Roster of Experts, knowledge of the Convention’s reporting and review processes, and the ability to coordinate an expert assignment concerning another country’s report. It would also need to manage international engagement, administration and funding arrangements for a short, focused research service. WSP UK LTD is a large supplier, showing that the buyer accepted a substantial professional-services provider for this requirement. Future credibility will depend on demonstrable climate, emissions-inventory or transparency-reporting expertise and reliable delivery for central government.
