Who Pays for Damage Caused to a Neighbour's Property During Building?
The building owner pays. Under the Party Wall etc. Act 1996 the person carrying out the work must compensate the adjoining owner for loss or damage caused by it, and must make good any physical damage or pay the cost of doing so.
The basic duty
This applies whether the damage was foreseeable or not, provided it was caused by the work covered by the Act. It does not depend on proving fault. It does depend on showing that the work caused the damage.
Why the schedule of condition matters
A record made before work starts shows what was there. Without one, arguments about cracks or stains are hard to settle. Ask for one to be part of the award.
| Cost item | Who normally pays | What drives it |
|---|---|---|
| Making good physical damage | Building owner | Extent of the damage and materials needed |
| Loss such as temporary inconvenience | Building owner, where recoverable | Duration and evidence of loss |
| Surveyors' inspection fees | As the award directs | Number of visits and complexity |
| Contractor's insurer contribution | Insurer, subject to policy terms | Cover in place and its exclusions |
| Damage the neighbour caused themselves | Neighbour | Evidence and causation |
How claims usually run
- The neighbour reports the damage promptly, in writing, with photographs.
- The surveyors inspect and compare with the schedule.
- The building owner arranges repair or agrees a payment.
- If they disagree, the surveyors decide, or a further route under the Act is used.
Damage outside the Act
Damage from work not covered by the Act may be dealt with under general law, such as negligence or nuisance. That is more complex and takes professional advice.
Insurance
Contractors' public liability cover and the building owner's own policy may respond to claims. Read the policy wording and tell your insurer early. Do not assume you are covered.
Keep every message with the neighbour and the contractor about damage. Dates, photographs and short factual notes are more useful than long complaints. If the damage is urgent, such as a leak, tell the contractor and your surveyor at once.
Frequently asked questions
Do I pay for old cracks?
No, if the records show they were already there. That is why a schedule of condition matters.
How fast should the neighbour report damage?
Promptly. Delay makes causation harder to prove.
Can the neighbour ask for money upfront?
They can ask for security for expenses, which surveyors may award.
