National Highways v WSP: contract dispute implications for net zero road projects
Reviewed by Joe Ashwell

First reported on New Civil Engineer
30 Second Briefing
National Highways has lodged a High Court breach of contract claim against WSP over the consultancy’s role as lead advisor on its roadmap to net zero for the strategic road network. The dispute centres on advisory work underpinning National Highways’ decarbonisation strategy, which covers construction materials, maintenance regimes and operational emissions across England’s motorways and major A-roads. Any adverse ruling or settlement could reshape how UK infrastructure clients scope, procure and manage consultancy input on carbon baselining, lifecycle assessments and compliance with government net zero targets.
Technical Brief
- National Highways has escalated the dispute to the High Court, indicating a formally litigated contract claim.
- WSP’s role is defined contractually as “lead advisor”, implying single-point responsibility for key deliverables.
- The claim is framed explicitly as “breach of contract”, not professional negligence or judicial review.
Our Take
National Highways features heavily in our Policy coverage, and the mix of this dispute with pieces on hydrogen-powered compounds and road safety upgrades suggests the agency is under simultaneous pressure on decarbonisation delivery, safety performance and commercial governance.
Given the Department for Transport’s £1.1bn innovation spend flagged by the National Audit Office, a public contract breach case in the United Kingdom involving National Highways and WSP could harden risk management and documentation standards across future DfT-backed consultancy frameworks.
