Potholes now cost UK drivers £3.3bn a year in repairs – and one businessman started fixing them himself

A pothole is not the problem. It’s the symptom that finally became visible.

A repair bill, a ranking of bad roads, a resident out with a shovel – none of these are really about the pothole itself. They’re about what’s failing underneath it.

The bill: billions, every year

Fresh research this week put a number on what that failure costs drivers directly. Pothole-related vehicle damage is running into the billions annually across the UK, in tyres, suspension and wheel repairs. It’s a figure that tends to get reported in isolation, as if it were the whole story. It’s actually the most measurable part of a much bigger one, because for every pound a driver spends on a damaged wheel, a local authority is spending on repeated, short-term fixes to the same stretch of road.

The ranking: useful pressure, wrong focus

Alongside the cost figures, national coverage has again named the roads with the highest levels of reported potholes and repairs. Lists like this generate attention because they turn a national problem into something specific and shareable. But they can be misleading. A road at the top of a “worst potholes” list isn’t necessarily worse-built than its neighbours, it may simply be the one where deterioration below the surface has progressed furthest, fastest. The ranking measures the visible symptom. It says almost nothing about the cause.

What’s actually failing

Underneath every carriageway is a pavement structure, layers of material designed to spread traffic load and shed water. When water gets into that structure, through a crack or a failed joint, it weakens the layers beneath the surface. Traffic loading does the rest, flexing the weakened area until the surface above it collapses. That collapse is the pothole.

Patch it, and you’ve filled the visible hole. You haven’t touched the water damage around it, which is why patched potholes have a habit of reopening, sometimes within months, sometimes right next to the original repair. Surface dressing – a protective treatment using bitumen binder and stone chippings to extend the life of the existing carriageway – helps seal a road against water ingress before failure. Resurfacing goes further, replacing the damaged layer outright. Patching is the cheapest option and the one that treats the least.

That’s the structural reason reactive maintenance struggles to keep pace: it’s aimed at the wrong layer.

Why authorities keep patching anyway

Local highway authorities aren’t short of competing demands. Drainage, structures, footways, lighting and winter service all draw against the same maintenance budget as carriageway repairs, and a visible pothole tends to generate more immediate public pressure than an ageing drainage asset nobody can see. That pressure shapes where the money goes, even when it isn’t where the money would do most long-term good.

It’s this dynamic that occasionally spills into direct public action. In Aberdeenshire, a car dealership owner was reported carrying out his own temporary pothole repairs on roads around Kintore, frustrated by the pace of official maintenance. Unofficial repairs aren’t encouraged by authorities, for obvious liability and consistency reasons, but the story is a useful measure of how visible, and how personal, road condition has become for residents who feel a defect has gone unaddressed for too long.

Moving past the patch

The sector’s answer to this isn’t more patching crews, it’s better information about where to intervene before a defect appears at all. Data-led asset management, digital inspections and AI-assisted defect detection are increasingly used to flag deterioration in the pavement structure before it reaches the surface, letting authorities target surface dressing or resurfacing at the point where it will actually extend the life of the road, rather than reacting once it’s already failed.

None of that produces a dramatic before-and-after photo the way a filled pothole does. It’s also the only approach that changes the underlying number: not how many potholes get patched this year, but how many form in the first place.
