## Summary

The Environment Agency commissioned research and related consultancy to develop an analytical framework for saltmarsh denitrification. The work is intended to improve understanding of the drivers of denitrification in intact saltmarshes and to better capture relevant metrics. It builds on recommendations from earlier reports funded through the mNCEA and the Marine and Fisheries Research and Development programme, produced in collaboration with The Crown Estate. Existing report data provides initial benchmarks, although previous results showed variability. The requirement is classified as research and development services and related consultancy services. The buyer is the Environment Agency, a sub-central public authority. The contracting process concerns one service requirement, delivered for the Environment Agency’s environmental research purposes.

This procurement is complete and has been awarded to the UK Centre for Ecology & Hydrology. The contract was signed on 14 August 2026 and runs from 1 October 2026 to 31 March 2027. Its value is £43,099.35 excluding VAT, or £51,719.22 including VAT. The award was made for one lot. It used a selective procedure described as a below-threshold award under a framework, and was a non-competitive direct award. The selected supplier is the UK Centre for Ecology & Hydrology. The published procurement information does not set out a separate scored evaluation basis; the outcome records the framework award route rather than an open competition. The contract remains active during its stated period.

This opportunity indicates demand from the Environment Agency for specialist environmental research combining saltmarsh ecology, denitrification science, data analysis and consultancy. A credible future supplier would need to understand denitrification in intact saltmarshes, identify and assess the drivers affecting it, and develop an analytical framework capable of handling variable results. Experience of designing or applying environmental metrics, interpreting monitoring or research data, and turning findings into practical analytical methods would be relevant. Familiarity with publicly funded environmental research, previous evidence bases and collaboration across organisations would strengthen a supplier’s position. The selected organisation is a large ecology and hydrology research body, so competing providers would need comparable scientific expertise, research capacity and the ability to deliver a focused analytical study for the Environment Agency.

## Notice

Environment Agency self-service direct award. The Environment Agency (EA) want to investigate the development of an analytical framework that may better capture drivers of denitrification in intact saltmarshes. This work follows from recommendations from previous reports funded through the mNCEA and the Marine and Fisheries Research and Development programme, in collaboration with the Crown Estate (TCE). Data from these reports has already helped provide initial benchmarks for denitrification metrics, though results did show variability (Perring, Aberg et al. 2025, Perring, Aberg et al. 2026a).
