Summary of the contracting process

Natural England commissioned environmental consultancy to produce a high-level list of potential conservation measures for the River Wensum Special Area of Conservation. The measures are intended to benefit the site’s features affected by nutrient enrichment and are envisaged as lasting in perpetuity. The work is therefore focused on identifying and setting out suitable conservation interventions, rather than delivering a specified set of physical works. The named site is the River Wensum SAC; no narrower delivery location is stated. This requirement is relevant to environmental consultants with expertise in conservation planning and nutrient-affected habitats or protected sites, particularly those able to develop practical measures for long-term benefit.

The procurement is complete and was awarded to Swallowtail Consulting Ltd. The contract was signed on 9 July 2026, with a stated period from 10 July to 4 September 2026. Its value is £17,988 excluding VAT (£21,585.60 including VAT). The original tender estimated £12,000 excluding VAT (£14,400 including VAT). Natural England used an open, below-threshold competition. The requirement was arranged as one lot, with technical quality weighted at 65% and the commercial submission at 35%. The tender submission deadline was 1 July 2026, following an amendment to the enquiry and submission deadlines. A contract associated with an earlier award entry is marked terminated; the termination notice gives no reason, while its record says it corrected an administrative error.

For firms considering comparable future work from Natural England, this award demonstrates demand for concise, high-level conservation planning tied to a defined protected site and a specific environmental pressure. A credible supplier would need to understand how nutrient enrichment affects conservation features and be able to identify measures that could benefit them over the long term. The competition placed greater weight on the technical submission than on price, so strong evidence of relevant environmental expertise and a clear, well-reasoned approach would matter alongside commercial value. The scale is a focused consultancy assignment rather than a large delivery programme. Swallowtail Consulting Ltd was selected, showing that a specialist consultancy could deliver the requirement; the procurement does not establish a particular accreditation or minimum business size.
