Summary of the contracting process

Trydan Gwyrdd Cymru procured environmental baseline professional services for large-scale wind farm developments in Wales. The requirement was divided into two service areas. Baseline ornithology services cover vantage-point surveys recording target-species flight lines, breeding bird walkover surveys, species-specific surveys for Schedule 1 Wildlife and Countryside Act birds, and nightjar surveys. Baseline habitat services cover peat and soil probing, Phase 1 and extended Phase 1 habitat surveys, and National Vegetation Classification surveys of semi-natural plant communities. The buyer is Trydan Gwyrdd Cymru, a Welsh public authority based in Merthyr Tydfil. The work is delivered in Wales. Both lots were identified as suitable for small and medium-sized enterprises and voluntary, community and social enterprises.

This procurement has been awarded and the contracts are active. Lot 1, Baseline Ornithological Services, was awarded on 6 July 2026 to BSG Ecology Ltd, Jacobs U.K. Limited, Land Use Consultants Limited and Atmos Consulting Limited for £1,400,000 excluding VAT (£1,680,000 including VAT). The contract was signed on 23 July 2026 and runs from 27 July 2026 to 26 July 2030. Lot 2, Baseline Habitat Services, was awarded on 6 July 2026 to BSG Ecology Ltd, Jacobs U.K. Limited, Land Use Consultants Limited and RSK ADAS Limited for £350,000 excluding VAT (£420,000 including VAT). Its contract was signed on 23 July 2026 and runs from 27 July 2026 to 26 July 2030. The open procedure used a closed framework, with call-offs through mini-competition or direct award. Evaluation weighted technical quality at 70% and commercial cost at 30%.

This award demonstrates sustained demand from Trydan Gwyrdd Cymru for ecological evidence supporting large-scale wind farm development in Wales. A credible future competitor would need teams able to plan and deliver ornithological fieldwork, including vantage-point, breeding-bird, Schedule 1 species and nightjar surveys, alongside robust reporting. For habitat work, relevant capability includes peat and soil probing, Phase 1 and extended Phase 1 habitat assessment, and National Vegetation Classification of semi-natural plant communities. Suppliers should be able to provide technically strong written responses and commercially competitive proposals, since technical quality carried more weight than cost. The successful field is mixed, including specialist SMEs and larger environmental consultancies, indicating that both focused ecological practices and organisations with broader delivery capacity can compete. Familiarity with Welsh wind farm consenting requirements and dependable multi-disciplinary resource would strengthen credibility.
