## Summary

London Borough of Bromley commissioned water quality monitoring, citizen science and community engagement services for the Keston Ponds Restoration Project. The work combines monitoring water quality with involving local people in citizen science and community engagement activities. It is an environmental and technical services requirement, associated with engineering and inspection services (CPV 71000000). Delivery is in Bromley, where the Keston Ponds project is based. The selected supplier, Thames21 Limited, is a London-based environmental organisation. The requirement concerns the restoration project rather than a general borough-wide monitoring programme, so suppliers with relevant pond or freshwater monitoring and community engagement experience are the closest fit.

The procurement is complete and the contract has been awarded to Thames21 Limited. Bromley used a below-threshold limited competition, with one lot. The award is active, and the contract was signed on 30 September 2026. Its period runs from 30 September 2026 to 31 March 2029. The contract value is £81,380 excluding VAT (£97,656 including VAT). The published procurement information does not describe the evaluation criteria, so the basis on which bids were assessed cannot be stated. This was a services contract for the Keston Ponds Restoration Project, rather than a works contract to carry out the pond restoration itself.

For a future Keston Ponds requirement, credible suppliers are likely to combine practical freshwater or pond water-quality monitoring with the ability to involve residents and support citizen science. Experience translating monitoring activity into useful community engagement would be relevant, as would the capacity to sustain work across a multi-year project. This award shows Bromley used a limited competition for a below-threshold services requirement and selected Thames21, an organisation operating in environmental services. Suppliers with a track record of delivering both technical monitoring and public-facing engagement for restoration projects would be well placed to demonstrate a close match. The work is specifically tied to Keston Ponds, so evidence of freshwater restoration and community participation is more pertinent than broader environmental services alone.
