## Summary

Great British Energy - Nuclear commissioned archaeological investigation and mitigation at the Gywndod site. The work covers the priority Phase 1 package, enabling critical-path site works to proceed while a separate, larger competitive procurement is carried out for the remainder of the archaeological work. This is a specialist archaeological services requirement, classified under CPV 71351914. The buying organisation is Great British Energy - Nuclear, based in Warrington. The stated delivery location is the United Kingdom; the procurement data also lists a number of other broad locations, but does not identify a specific town or site address for delivery. The requirement is framed around investigation and mitigation at Gywndod rather than a general archaeological services programme.

The procurement is complete and has been awarded to Perfect Circle JV Ltd. Great British Energy - Nuclear used a single-supplier framework route through the SCAPE Framework, which the description says was competitively tendered. The award date was 15 October 2026. The awarded value is £5,000,000. The contract period runs from 15 October 2026 to 14 October 2027. This is a single priority Phase 1 delivery agreement; the broader archaeological works are to be covered by a separate competitive exercise. The data marks the requirement as suitable for small and medium-sized enterprises. Evaluation criteria and specific supplier eligibility conditions are not set out in the procurement information.

This award demonstrates demand from Great British Energy - Nuclear for archaeological investigation and mitigation tied to priority site works at Gywndod. A credible competitor for a comparable requirement would need to deliver specialist archaeological field investigation and mitigation in a way that supports construction critical paths, with the capacity to mobilise and coordinate work alongside a wider site programme. The selected route was a competitively tendered single-supplier framework, so relevant framework access and a track record of winning and delivering public-sector work through such arrangements would be commercially pertinent. The buyer marked the work as suitable for SMEs, indicating that smaller specialists may be relevant competitors, potentially with delivery partners where the package requires greater capacity. The priority package formed part of a larger archaeological programme, so bidders would need to show they can manage a focused phase while fitting with subsequent site-wide procurement.

## Notice

A new Delivery Agreement with Perfect Circle via the SCAPE Framework (competitively tendered single supplier framework) has been put in place to cover the Priority Phase 1 archaeological investigation and mitigation works at the Gywndod site. This is so that critical path works can commence while a larger competitive procurement exercise is undertaken for the remainder of archaeological works on the site.
