Who's liable when paving work goes wrong

This is general information, not legal advice. Liability depends on the specific facts of a situation, so if you’re dealing with an actual dispute or damage, get advice suited to your case.

Most paving jobs go smoothly, but when something does go wrong, whether it’s damage during the work or a problem that shows up afterwards, knowing roughly where responsibility sits helps you respond calmly instead of guessing.

Before work starts: what protects you

A contractor’s public liability insurance is the main protection if their work accidentally damages your property, a neighbour’s property, or public infrastructure like a pavement or drain during the job. Ask to see proof of this before work begins; a reputable contractor won’t hesitate to show it, and a hesitant answer is worth noting. Alongside insurance, a written contract or quote that spells out the scope of work, materials and any guarantee terms is what you’ll rely on if a dispute arises later, since a verbal agreement gives you far less to point to. Insurance and guarantees cover the work itself; separate paperwork like planning permission or a dropped kerb application is its own process, covered in our guide on driveway permits, planning permission and dropped kerbs.

During the work: accidental damage

If a contractor’s van, skip or machinery damages a driveway, wall, drain or a neighbour’s property while working on your job, their public liability insurance is generally what covers that kind of accidental damage, not your own home insurance. Document any damage with photos as soon as you notice it and raise it with the contractor directly and promptly, since delays make it harder to establish when and how something happened.

After the work: when paving fails early

Paving that sinks, cracks or drains badly within a year or two of installation is usually a workmanship issue rather than an insurance matter, and this is where a written guarantee earns its keep. Most reputable contractors offer some form of workmanship warranty, commonly covering settling or drainage failure for a set period, and a contractor who won’t put a guarantee in writing is telling you something before the work even starts.

When a neighbour is involved

Paving jobs sometimes affect a neighbour directly, a shared driveway, materials stored temporarily on a boundary, or a skip that partly blocks their access. If a contractor’s work damages a neighbour’s property or a dispute arises over shared access, the same public liability insurance principle applies: it’s generally the contractor’s responsibility to make good accidental damage caused by their work, not yours as the person who hired them, though this is worth confirming directly with the contractor before work starts rather than assuming.

Why a written guarantee matters more than a verbal promise

A verbal assurance that “we’ll sort it if anything goes wrong” is only as good as the contractor’s memory and continued goodwill a year or two later. A written guarantee, ideally naming what’s covered (settling, cracking, drainage failure) and for how long, gives you something concrete to point back to if the contractor is reluctant or has moved on. It’s worth asking for this in writing at the quote stage, since a contractor confident in their work has little reason to avoid putting it on paper.

Who typically covers what

Situation	Usually covered by
Contractor’s machinery damages your drain, wall or a neighbour’s property during the job	The contractor’s public liability insurance
Driveway sinks or cracks within the guarantee period	The contractor’s workmanship warranty
A visitor trips on paving that’s genuinely hazardous	Depends on the circumstances; specific advice needed
A dispute over quality that isn’t resolving directly	Consumer advice services, then possibly formal action

If a dispute doesn’t resolve directly

Keep a clear record: the original quote, photos before and after, and any messages exchanged about the problem. Most disputes resolve faster with this kind of documentation than without it. If talking to the contractor directly doesn’t lead anywhere, a free consumer advice service can point you toward the right next step for your specific situation, which is more useful than general guidance at that stage.

Vetting a contractor properly before you hire, checking insurance, getting a written quote and guarantee, cuts down the odds of ending up in this situation at all.
