## Summary

Great British Energy - Nuclear commissioned archaeological investigation and mitigation works at its Gwyndod site. The work covers the Priority Phase 1 archaeological programme, including excavation at archaeological sites, and is intended to let critical-path site works begin while the wider archaeological works are procured separately. The buying organisation is Great British Energy - Nuclear. The requirement is archaeological services, rather than general construction or consultancy work.

The procurement is complete and the contract was awarded to Perfect Circle JV Ltd. The contract is active and was signed on 15 October 2026, with a value of £5,000,000. The procurement used a limited award route without a separate prior competition, through the SCAPE competitively tendered single-supplier framework. Price was the stated award criterion, and one bid was recorded. The agreement covers Priority Phase 1 only; it was put in place to support critical-path works while a larger competitive procurement is undertaken for the remaining archaeology at the site. The available contract information does not state its duration.

For suppliers considering comparable future work for Great British Energy - Nuclear, this award demonstrates demand for archaeological investigation and mitigation that can support critical-path delivery at a major energy site. Credible competitors would need to deliver site-based archaeology, including excavation, and coordinate mitigation with the sequencing of wider site works. The buyer used a competitively tendered single-supplier framework to place this delivery agreement, making framework access and the ability to mobilise through that route commercially relevant. The awarded supplier is a large joint-venture company, and subcontracting is involved. The requirement is a defined priority phase, distinct from the larger body of archaeological work planned for the site.

## Notice
