WSP wins all three lots on the Environment Agency's new National Groundwater Modelling Framework, strengthening its public infrastructure disputes and advisory portfolio
Engineering consultancy WSP has secured appointments across all three specialist lots of the Environment Agency's new National Groundwater Modelling Framework, covering regional groundwater modelling, groundwater flood assessment, and independent technical review. The framework has been established to give the Environment Agency structured access to specialist hydrogeological expertise and greater visibility of its future programme of work. WSP will draw on what it describes as one of the largest specialist groundwater teams in the UK to support projects delivered through the framework, which is intended to improve flood forecasting, drought planning, and the long-term protection of water resources. The appointment builds on a strong period of public sector wins for the firm: earlier in 2026, WSP partnered with Mott MacDonald on a £25 million contract supporting environmental assessment and permitting work for the UK's first Small Modular Reactor (SMR) development at Wylfa on Anglesey. WSP also holds a place on Transport for London's Professional Services Framework. For commercial lawyers advising on infrastructure procurement and public contract disputes, the groundwater framework illustrates how specialist environmental modelling capacity is increasingly being packaged through multi-lot frameworks that concentrate work with a small number of approved suppliers, creating both procurement law questions (on framework structure and award criteria) and potential disputes if a losing bidder challenges the award.
Why this matters
Large multi-lot framework contracts of this type sit at the intersection of public procurement law and environmental regulation, an area of increasing importance as the UK government accelerates infrastructure investment under the new administration. A clean sweep of all three lots by one consultancy will attract scrutiny from competitors on market concentration grounds, and any challenge would engage the UK's public procurement regulations and the Environment Agency's own procurement policies. The SMR connection (WSP's earlier Wylfa contract with Mott MacDonald) signals that the same consultancy relationships are being built across multiple critical infrastructure programmes simultaneously, which is relevant context for any lawyer advising on the legal framework governing these appointment structures.
On the Ground
On a public procurement matter of this type, a trainee would be reviewing the framework award criteria against the applicable procurement regulations, preparing a chronology of the tender process for a potential challenge, and assisting with disclosure review if a losing bidder brings a claim.
Interview prep
Question you might get
“What grounds could a losing bidder rely on to challenge a public framework contract award, and what is the typical procedural timeline for bringing such a claim in England?”
