FM Conway Secures £1.25 Billion Westminster Highways and Public Realm Contract

An 8.5-year contract with extension options covering the full spectrum of highway asset management signals sustained opportunity across the Westminster supply chain.

Infrastructure services provider FM Conway, working alongside professional services firm WSP, has been appointed by Westminster City Council to deliver a major highways and public realm contract valued at £1.25 billion over 12.5 years.

The contract covers design, construction, inspection and maintenance of Westminster’s public highway assets, including carriageways, footways, street lighting, drainage, bridges and structures, alongside support for a range of regulatory functions. Awarded for an initial 8.5-year term with the option to extend for a further four years, the contract represents one of the most significant local authority highway awards in the UK.

FM Conway will self-deliver the core scope but has confirmed it will draw on a network of specialist local supply chain partners to support delivery. That model – prioritising local expertise alongside FM Conway’s own integrated digital delivery capability and the broader resources of parent company Vinci Group – is central to the council’s expectations around quality, accountability and value for money.

WSP will lead on public realm design, flood risk management and road safety, bringing more than two decades of experience delivering complex urban infrastructure in Westminster. Their established working relationship with FM Conway underpins the coordinated design approach the contract demands.

The award builds on a track record that includes the Strand Aldwych transformation and delivery of road surfacing on Elmfield Way using material with a UK-best 92% recycled content. Net zero commitments and climate resilience are embedded throughout the new contract terms, with tougher performance standards, independent assurance and improved digital reporting forming part of a strengthened oversight framework introduced by the council.

Councillor Tim Mitchell, Westminster Cabinet Member for Environment and City Management, confirmed the award followed a robust, multi-bidder competition and described the new arrangements as delivering “clearer accountability, stronger oversight, and better value for money.”

For supply chain businesses, the contract’s long duration and broad asset scope – spanning carriageways, structures, drainage, lighting and public realm – points to sustained demand across civil engineering, specialist maintenance, materials supply, sustainability, and digital infrastructure services.

Capability areas relevant to this opportunity include: highway design and construction, carriageway and footway maintenance, drainage and flood risk, structures and bridges, street lighting, sustainable materials and low carbon surfacing, digital asset management, public realm design, and social value delivery.
