Summary of the contracting process

Southern Water Services Limited purchased 19 Biodiversity Performance Commitment (BPC) Units. The requirement is an environmental service supporting the water company’s biodiversity commitments, with the units supplied for activity in the United Kingdom. The procurement covers one service requirement rather than separate work packages. It is relevant to organisations that create, manage or supply biodiversity-related environmental outcomes which can be recognised as BPC Units. The selected supplier, Aspect Nature Reserve Limited, is based in Epsom and is classified as a large organisation. Southern Water is a private water utility, so the work relates to the environmental obligations and operational needs of a regulated water company. Businesses with a direct role in biodiversity performance delivery should assess the requirement and its associated unit structure.

The procurement is complete and a supplier has been selected through a direct award. The contract was awarded to Aspect Nature Reserve Limited for £494,000 excluding VAT, or £592,800 including VAT. The contract period runs from 18 August 2026 to 17 August 2056. Southern Water used a direct award because Ofwat requires each water company to purchase 115 BPC Units, and the buyer cited the complexity and timescale for meeting that requirement. The procurement was treated as urgent and followed the utilities regime. There was one lot, covering the purchase of 19 BPC Units, and the award is above the applicable threshold. The lot was identified as suitable for small and medium-sized enterprises and voluntary, community or social enterprises.

This award demonstrates a substantial, long-term requirement from Southern Water for biodiversity performance units as part of a regulated water company’s environmental commitments. Competitors would need to provide recognised Biodiversity Performance Commitment Units at the required scale and demonstrate that their environmental services can support the buyer’s compliance needs. The successful supplier profile shows that a large specialist environmental organisation can satisfy the requirement, while the lot was also considered suitable for smaller businesses and voluntary, community or social enterprises. Relevant capabilities include delivering measurable biodiversity outcomes, managing the underlying environmental activity, and providing reliable evidence that units meet the buyer’s requirements. Suppliers able to combine ecological delivery with robust unit administration and long-term performance assurance would be well placed when this buyer next reviews a similar need.
