What Connect Plus M25 does

Connect Plus (M25) Limited is a privately held UK infrastructure concession company that holds the DBFO (Design, Build, Finance and Operate) contract with National Highways to manage and operate the M25 motorway network — the busiest road in the United Kingdom. The legal entity contracts through Connect Plus Services, an unincorporated joint venture between Balfour Beatty Civil Engineering Limited, Egis Road Operation UK Limited, and AtkinsRéalis Limited, which delivers the day-to-day operations and maintenance scope. The company employs 600+ staff distributed across a headquarters in South Mimms and six operational depots/control facilities (Dartford, Epping, Denham, Leatherhead, Scratchwood, Swanley).

The operating model centres on 24/7 control room monitoring from Dartford using 478 National Highways cameras and specialist heat-map sensors, GPS-tracked fleet deployment, and a winter service operation with 35 dedicated gritting vehicles, 61 winter fleet vehicles, 140 qualified drivers, and 8 winter service depots covering approximately 2,678 km of carriageway across 27 predefined treatment routes. The service portfolio includes routine and cyclical maintenance (litter picking, vegetation clearance, road maintenance), incident response and defect management, asset and project delivery for network renewals, roadspace coordination, safety management, and Dartford tunnel operations under ADR Category C regulations for dangerous goods. Recent operational initiatives include hydrogen-powered vehicle trials and renewable energy procurement.

Revenue is derived exclusively from the long-term government infrastructure contract with National Highways; the company has no commercial sales motion and operates as a B2G concessionaire rather than a product vendor. Pricing and contract terms are not publicly disclosed. The company has maintained ISO 44001 Collaborative Business Relationship Management accreditation for 11 consecutive years and is led by CEO Angus Murray.
