## Summary

Natural England is seeking a specialist geomorphological and ecological survey of Porlock Ridge and Saltmarsh Site of Special Scientific Interest (SSSI). The work involves assessing the landform processes and ecological characteristics of the ridge and saltmarsh, supporting Natural England’s environmental monitoring and management responsibilities. This is a professional surveying and environmental assessment service rather than construction, maintenance or the supply of equipment. The requirement is for work at Porlock Ridge and Saltmarsh SSSI in Somerset. Businesses with expertise in coastal geomorphology, saltmarsh systems, ecological field assessment and protected-site survey work are likely to find the scope relevant. The procurement is being run by Natural England, a central government public authority.

The procurement has reached tender: Natural England invited quotations through a below-threshold open competition. Suppliers must submit a quotation meeting the Request for Quotation requirements by email; electronic submission through an online tendering system is not used. The buyer set the submission deadline as 11 September 2026 at 23:59 UK time. The contract period is 14 September 2026 to 30 March 2027. The estimated value is £16,667 excluding VAT, or £20,000 including VAT. There is one lot. Evaluation is based on the requirements and details in the RFQ, with the updated RFQ forming part of the tender information. Clarification questions are submitted by email and may be circulated with responses to tenderers.

This opportunity suits environmental consultancies, ecological survey practices and specialist surveying firms able to combine geomorphological and ecological assessment in a coastal protected site. Relevant capability includes understanding coastal landforms, ridge and saltmarsh processes, habitat and ecological conditions, and carrying out structured field surveys that meet the RFQ requirements. Suppliers should be able to plan and deliver a joined-up assessment, interpret environmental observations and present clear findings for a public-sector nature conservation body. Experience of working on Sites of Special Scientific Interest or comparable designated coastal sites would be well aligned with the requirement. The single-lot scope is suited to a focused specialist provider or a multidisciplinary team with the necessary environmental survey expertise.
