The project, which falls under the industry category of surveying services, involved an open procurement method with a below-threshold competition. The procurement reached its award stage on 9 June 2026, and the contract was signed on 20 May 2026. The overall project aims to complete surveys by the end of summer 2026, with the final report due by February 2027. Key locations for the service delivery are primarily in the UKH region, with an approximate contract value in the region of £24,894.12 to £29,872.94. This tender represents a substantial opportunity for businesses specialising in environmental surveying services, particularly those experienced in aquatic plant identification and assessment. Small and medium-sized enterprises (SMEs) were encouraged to apply through an open competition, which creates ample opportunities for business growth for those capable of meeting specific technical demands and geographic requirements. Successful engagement in such public sector contracts can provide significant business credibility and potential for future work within governmental and environmental projects. ADLER & ALLAN LIMITED, a large-scale enterprise, was eventually appointed as the supplier, which underscores the competitive nature of this procurement process while highlighting the scale and expertise potentially required for such ambitious assessments. ## Notice This survey is being sought by the West Anglia Area Team for aquatic plant survey and condition assessment of the Nene Washes ditch network, 20km long Morton's Leam at the Nene Washes and of the Counter Drain and Delph channels (both ca. 30km long) at Ouse Washes Protected Sites, Cambridgeshire. This will require Common Standards Monitoring surveys of the ditches across the Nene Washes and modified CSM ditch surveys in the Counter and Delph drains at the Ouse Washes and in at the Nene Washes as described in the Request for Quotation. The surveys must be carried out over summer 2026 (the Counter Drain at the Ouse Washes must be surveyed in full before 01 July after which it is cut) with the final report to be submitted at the end of February 2027. Extensive experience in identification of aquatic plants is required for this project across these two large sites. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/054100-2026 | | Notice type | UK7 - Contract Details Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Below threshold - open competition | | Tender suitability | SME | | Awardee scale | Large | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 9 Jun 2026 | | Submission deadline | 13 May 2026 | | Future notice date | Not specified | | Award date | 19 May 2026 | | Contract period | 24 May 2026 - 27 Jul 2027 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £20,800 | | Lots value | £20,800 | | Awards value | Not specified | | Contracts value | £24,894 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | NATURAL ENGLAND | | Locality | LONDON | | Post town | 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 | TLH East (England) | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | ADLER & ALLAN | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services ### Codes - 71355000 - Surveying services ## Release History - 9 Jun 2026 at 09:05 - Award - UK7 - Contract Details Notice - https://www.find-tender.service.gov.uk/Notice/054100-2026 - 8 May 2026 at 14:08 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/042615-2026 - 7 May 2026 at 07:12 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/041664-2026 - 17 Apr 2026 at 06:04 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/034927-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/054100-2026 9th June 2026 - Contract details notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/042615-2026 8th May 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/041664-2026 7th May 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/034927-2026 17th April 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/Attachment/A-14784 Request for Quotation - https://www.find-tender.service.gov.uk/Notice/Attachment/A-14785 Commercial Response - https://www.find-tender.service.gov.uk/Notice/Attachment/A-14786 Order form - https://www.find-tender.service.gov.uk/Notice/Attachment/A-15765 Clarification Q&A - https://www.find-tender.service.gov.uk/Notice/Attachment/A-15900 Indicative Sample Points - https://www.find-tender.service.gov.uk/Notice/Attachment/A-15939 Updated RFQ with extended dates ## Notice URLs - http://www.adlerandallan.co.uk - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
