This newly completed tender falls under the environmental services category, with activity spanning across the UK and was procured via an open competition below the threshold. The contract award took place on 27th June 2025, with the service provision scheduled from 30th June to 11th August 2025. Key aspects of this tender include the design of a methodology for calculating nutrient reductions and the development of a GIS-based tool, emphasising collaboration and data analytics to enhance environmental outcomes. This tender creates significant growth opportunities for small and medium enterprises (SMEs), especially those involved in environmental analytics, GIS technology, and sustainable development. Businesses with experience in environmental impact assessment and tool development for nutrient mitigation will find this project particularly well-matched to their capabilities. By being a part of this initiative, companies can enhance their portfolios and establish strong partnerships with a reputable public entity like Natural England. The focus on developing robust methodological standards for nutrient neutrality provides businesses the chance to innovatively contribute to a pivotal environmental endeavour. ## Notice Natural England is developing the Conservation Measures Standard to underpin the delivery of the NRF. Part of this work requires a methodology and tool for quantify the nutrient reductions generated through implementing riparian buffer strips (RBS) in Nutrient Neutrality (NN) catchments to improve water quality. This tool will facilitate mitigation scheme suppliers to design and deliver robust RBS to generate nutrient reductions capable of offsetting nutrient inputs from development in NN catchments. This tool and its associated guidance will be part of a wider project Natural England has begun to produce standardised tools, guidance and assessment criteria to ensure conservation measure projects (mitigation schemes) are effective at achieving the intended environmental outcome. This project, the Conservation Measures Standard (CMS), will develop Solution Toolkits for each of the measure relied upon to deliver nutrient mitigation, prioritising the most effective and commonly used measures to allow scheme suppliers to design and implement high-quality schemes in accordance with the set standard. This request for work will build on existing work on RBS to generate nutrient mitigation by commissioning a comprehensive methodology and tool to accurately quantify the nutrient reduction achieved at a project scale through the implementation of RBS. The commission forms two parts, the first request is to design a robust methodology to calculate the N and P reduction achieved in kg/year by implementing a RBS project in a NN catchment. This will need to be developed in collaboration with NE and should incorporate the existing evidence base commissioned by NE. The second part of this commission is to use GIS and data science/analytics to develop a tool to enable site specific calculations for N and P reductions achieved by a RBS project. This must be based on the above methodology and should incorporate a level of precaution to account for any uncertainty. The work should align with other publications and tools generated by NE to quantify the nutrient inputs resulting from new development (Nutrient Neutrality calculators) and to quantify the nutrient reductions achieved by Nature-based Solutions/mitigation measures (Cover Crop calculators). ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/035830-2025 | | Notice type | UK7 -
