## Summary

Natural England is seeking surveying and geomorphology services to analyse decadal-scale sediment budgets and landform change across Sites of Special Scientific Interest (SSSI) dune systems in England. The work is to assess and quantify changes in dune-field sediment volume and how topography varies over time and across locations, using LiDAR (Light Detection and Ranging) data. Delivery covers dune sites across England. The requirement is relevant to organisations able to undertake or analyse geospatial and elevation data for coastal and dune environments, particularly where this supports understanding of sediment movement and geomorphic change. The buyer is Natural England, the government body responsible for nature conservation in England.

Natural England invited offers through an open competition for this services contract. The procurement reached the tender stage. The submission deadline was 26 October 2026 at 12 noon. The contract period was set to run from 2 November 2026 to 30 March 2027. The estimated value is £41,667 excluding VAT (£50,000 including VAT). The requirement is arranged as one lot. The award basis is described as being set out in the Request for Quotation. Quotations were to be submitted by email in response to the RFQ; clarification questions were also to be sent by email, with non-commercially sensitive questions and answers circulated to tenderers. The RFQ contains the detailed requirements and evaluation information.

This opportunity suits suppliers with the technical ability to process and interpret LiDAR data and quantify changes in dune topography and sediment volumes over decadal timescales. Relevant expertise may include surveying, coastal geomorphology, spatial analysis and the handling of elevation datasets across multiple sites. Suppliers should be able to deliver analysis covering dune systems in England and produce findings on both the amount and spatial and temporal variation of sediment and landform change. The work is a focused, single-lot commission rather than a large multi-lot programme, so it may suit specialist consultancies or research and surveying teams able to undertake a defined analytical assignment within the stated contract period. The RFQ sets out the detailed delivery requirements.
