The surveys cover agricultural fields and other open habitats within 10 km of the estuary, at 40 sample locations. The resulting data will help identify potentially suitable habitat for wintering waterbirds and wading birds associated with the estuary, improving understanding of their distribution across the surrounding landscape. The work is environmental survey services, delivered in the Humber area of England. It is a focused field-survey commission supporting habitat modelling, rather than a general habitat-management or restoration project. Natural England invited offers through an open competition under a below-threshold procedure. Suppliers were asked to submit a quotation by 23:59 on 23 November 2026; clarification questions were to be sent by email. The contract period runs from 1 January to 19 March 2027, with surveys required between January and the end of February, or into early March if needed. The estimated value is £49,999 excluding VAT (£59,998.80 including VAT). The procurement is divided into one lot, which is identified as suitable for SMEs. The award criteria are set out in the Request for Quotation. An amendment added Phase 1 sample shapefiles. This commission is suited to environmental consultancies and specialist ecological survey teams able to plan and carry out wintering bird surveys across agricultural fields and other open habitats. Suppliers will need the field capacity to survey 40 sample locations across the Humber Estuary’s surrounding landscape within the winter survey window. Relevant expertise in surveying wintering waterbirds and wading birds, and in collecting reliable data that can support habitat suitability modelling, is directly applicable. The work may suit an SME with experienced surveyors and the ability to manage geographically distributed fieldwork. The specified requirement centres on survey delivery and usable ecological data; the procurement information also identifies sample shapefiles as added material for the project. ## Notice This project involves undertaking wintering bird surveys in agricultural fields and other open habitats up to 10 km from the Humber Estuary SPA. The aim of this project is to collect additional data to support a Natural England-led Habitat Suitability Modelling project. The modelling is intended to help identify areas of potentially suitable habitat for wintering waterbirds and wading bird species associated with the Humber Estuary SPA, helping to improve our understanding of their distribution in the surrounding landscape. This commission requires wintering bird surveys at 40 sample locations between January and the end of February (or early March if required). ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/103809-2026 | | Notice type | UK4 - Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Below threshold - open competition | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 2 Nov 2026 | | Submission deadline | 23 Nov 2026 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 1 Jan 2027 - 19 Mar 2027 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £49,999 | | Lots value | £49,999 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Active | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | Natural England | | Locality | LONDON | | Postcode area | South West London | | Postcode | SW1P 4DF | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | TLE Yorkshire and The Humber | ## CPV Codes ### Divisions - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 90700000 - Environmental services ## Release History - 2 Nov 2026 at 14:52 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/103809-2026 - 2 Nov 2026 at 14:30 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/103786-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/103809-2026 2nd November 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/103786-2026 2nd November 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/Attachment/A-25020 RFQ - https://www.find-tender.service.gov.uk/Notice/Attachment/A-25021 Order Form - https://www.find-tender.service.gov.uk/Notice/Attachment/A-25022 Commercial Response Template - https://www.find-tender.service.gov.uk/Notice/Attachment/A-25035 ## Notice URLs - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
