Summary of the contracting process

Natural England, a central government public authority based in London, is overseeing a tender for the "Development of a network of hydrological monitoring across the Long Term Monitoring Network: North Solent". This project is part of their Long Term Monitoring Network, aimed at assessing ecosystem changes at National Nature Reserves. The procurement process is currently in the tender stage, with submissions due by 9am on 24th November 2025. The tender falls under the 'services' category, specifically for oceanography and hydrology services, and environmental monitoring. The open competition procurement method will be used, and the contract, valued at £12,500, is scheduled to commence on 27th November 2025 and conclude by 16th March 2026.

This tender represents a significant opportunity for businesses specialising in environmental services, particularly those with expertise in hydrology and ecosystem monitoring. Companies dedicated to developing conceptual hydrological models and those capable of establishing hydrological networks are well-suited for this project. Small and medium-sized enterprises (SMEs) are encouraged to participate, given the procurement method's focus on open competition. Winning this contract could enhance a firm’s portfolio, particularly for those looking to expand their services within public-sector contracts and ecosystem analysis work.

Notice Information

Notice Title

Development of a network of hydrological monitoring across the Long Term Monitoring Network: North Solent

Notice Description

Natural England's Long Term Monitoring Network (LTMN) started collecting data in 2010, aiming to identify if and how ecosystems are changing and, where relevant, to attribute that change to large-scale ecosystem pressures. Data is collected across 37 sites, most of which are National Nature Reserves. Alongside other data collection, there are approximately 50 permanent vegetation plots and 5 permanent soil plots at each site. Hydrological change is considered to be a potentially significant driver of ecosystem change on all LTMN water -dependent sites, but it is currently poorly understood. This contact requires a conceptual hydrological model to be produced for North Solent NNR. This may be done as a desk based exercise using existing information, or through a site visit if appropriate. From this we require advice on suitable locations for a network of dipwells in relation to the permanent vegetation plots are likely to be impacted by hydrological change.
