England’s busiest ring road still tops the payments table and that tells you where motorway money really goes

National Highways contractors are often most visible as cones, closures and orange jackets, but the biggest payments show how much of England’s road network is really a long, expensive maintenance job.

The biggest names on England’s strategic road network are not always the ones pouring brand new concrete or cutting ribbons.

Often, they are the firms keeping ageing motorways working day after day: renewing surfacing, managing incidents, maintaining structures, replacing worn-out assets and dealing with the awkward fact that some of Britain’s busiest roads are also some of its oldest. That is less glamorous than a new bypass. It is also where a great deal of the money goes.

In brief:

• A new league table of National Highways contractors for 2025/2026 puts Connect Plus (M25) at number one by total paid.
• The payments cover work linked to major programmes including the concrete roads programme.
• The ranking underlines how much of England’s road spend sits in long-term operation, renewal and asset management rather than one-off builds.

What the National Highways contractors ranking really shows

The obvious reading of a supplier ranking is who won big. The more useful one is what kind of work now dominates the network. England’s motorways and major A roads need constant attention because traffic does not politely pause while assets age. Expansion joints fail. Drainage silts up. White lines vanish. Barriers get hit. Surfacing loses texture and skid resistance. Every one of those jobs is mundane until it suddenly is not.

That is why the M25 matters here. Connect Plus topping the table is not just a story about a contractor. It is a story about the orbital road around London, one of the country’s most complex pieces of highway infrastructure, and the sheer cost of keeping it functioning. Drivers experience that spending as overnight closures, narrow lanes, temporary speed limits and gantries over live traffic. The network experiences it as a permanent programme of inspection, maintenance and renewal.

Some of that workload sits inside high-profile programmes. The concrete roads programme, for example, is about more than fresh black surfacing on top. Older concrete carriageways can require intensive intervention, from treatment of the underlying structure to the replacement of upper layers and associated assets. That is one reason major renewals can feel disproportionately disruptive. They often are. The road remains open for most of the day, then turns into a tightly managed worksite at night, with every hour planned because reopening late on a strategic route ripples fast across a region. We saw a local version of that pressure recently in Reading’s overnight resurfacing programme, where the timetable had to fit around how people actually move.

There is also a useful corrective here for anyone who assumes roads spending is mainly about new schemes. It is not. A mature network spends heavily on staying usable. National Highways runs the strategic road network in England, and much of its most expensive work is about preserving capacity and safety on roads drivers already depend on every day. That means inspections, routine maintenance, capital renewals and response work, as well as improvement schemes.

For contractors, that mix changes the job. It rewards scale, traffic management capability, asset knowledge and the ability to work repeatedly on the same corridor without causing more disruption than necessary. It also favours firms set up for long frameworks and integrated delivery models, where the work is less a single project than a rolling obligation to keep a route in service.

For drivers, the practical point is simple enough. If a road seems to be in roadworks often, it may be because it is carrying extraordinary demand on infrastructure that cannot be allowed to drift into failure. Nobody posts celebratory photos of repaired drainage or renewed ironwork. Yet those are the jobs that stop standing water, reduce emergency closures and keep heavier interventions at bay for longer.

The ranking therefore says something slightly unfashionable but important about roads policy. Maintaining a strategic network is not a holding pattern while waiting for the next big capital announcement. It is the main event. New roads attract attention because they are visible and finite. Maintenance is less cinematic. It just determines whether the road still works on a wet Tuesday in November.

That makes the supplier table a useful map of where the pressure points are. Big payments tend to gather where traffic is heaviest, assets are most complex and the consequences of failure are highest. The M25 is the clearest case. But the same logic runs across England’s busiest motorways and trunk roads: if the network is old, busy and safety-critical, the money follows.

There is a final, slightly wry truth in all this. The most expensive road jobs are often the ones drivers would prefer never to notice at all. If the closure ends on time, the carriageway opens cleanly and the route keeps moving, the work has done its job. Which is inconvenient for anyone chasing glamour, but reassuring for everyone else trying to get home.
