Leak from the flat above: who is liable and how to claim
If water comes through your ceiling from the flat above, the usual route is to claim on your own buildings or contents insurance for the repairs to your side, subject to your excess. You do not need to prove the neighbour was at fault to claim on your own policy. The neighbour is only personally liable if they were negligent.
Key takeaways
- For damage to your side, you usually claim on your own buildings and/or contents insurance, subject to your excess.
- You do not have to prove the neighbour was at fault to claim on your own policy.
- The neighbour is only personally liable if they were negligent, not for a genuine one-off accident.
- Your insurer may recover its costs from the neighbour later through subrogation, without holding up your repairs.
- In flats, the lease often decides who claims and who pays the excess, so read it alongside your policy.
Who is actually liable for the damage?
This is the part most people get wrong. When water comes down from the flat above, your first instinct is that the neighbour caused it, so the neighbour should pay. In practice, for the damage to your own property, the usual route is to claim on your own insurance. That means your buildings insurance for structural damage such as ceilings, walls and flooring, and your contents insurance for damaged belongings. You pay your excess, which is the fixed amount you agree to cover yourself on any claim, and the insurer covers the rest of a valid claim.
The important point is that you do not need to prove the neighbour was at fault to claim on your own policy. Your cover responds to the water damage itself, not to who caused it. That is why claiming on your own insurance is normally the fastest way to get your home put right.
When is the neighbour personally liable?
A neighbour is only personally liable if they were negligent, meaning they failed to take reasonable care and that failure caused the damage. Two clear examples: they knew about a dripping pipe or a failing seal for weeks and did nothing, or they caused the leak through poor DIY, such as a badly fitted washing machine or a botched plumbing job. In cases like those, the neighbour, or more often their insurer, may be on the hook.
The flip side surprises people. A genuine one-off accidental leak with no negligence usually means the neighbour is not personally liable. Say a concealed pipe in the flat above fails overnight with no warning and no wrongdoing. Legally, that is often nobody's fault, so the neighbour does not have to "just pay" for your damage. This is exactly why your own policy exists, and why you claim on it rather than waiting for the neighbour to accept blame they may not legally owe.
How subrogation works behind the scenes
Once your insurer has settled your claim, it may try to recover its costs from the neighbour or their insurer. This is called subrogation, which simply means your insurer steps into your shoes to chase whoever was responsible. It happens in the background between the two insurers and does not usually delay putting your home right.
There can be a practical upside for you. If your insurer succeeds in recovering its outlay because the neighbour was at fault, you may get your excess refunded, since the loss was ultimately met by the responsible party. Ask your insurer whether that applies to your claim, because policies and outcomes vary.
Flats, freeholders and the lease
Flats add a layer that houses do not have. In many blocks, the buildings insurance is arranged by the freeholder or the management company under a single block policy that covers the whole building. Individual leaseholders then insure their own contents separately. So the structural repairs to your ceiling and walls might be claimed under the block policy, while your ruined sofa and carpets go through your own contents cover.
Who actually makes the claim, and who pays the excess, can depend on your lease. Some leases make the leaseholder responsible for the block policy excess on their own flat; others handle it differently. Read the lease alongside the policy wording before you assume anything. If you rent, your landlord or managing agent usually deals with the buildings side, so report the leak to them promptly as well as to the flat above.

What is covered, and what is not
A sudden internal leak is what insurers call escape of water, meaning water that escapes unexpectedly from a fixed system such as pipes, a tank, or a heating system. Escape of water is a standard part of most buildings and contents policies, so a burst pipe or a failed connection in the flat above is normally the kind of event you can claim for. Our escape of water claim guide explains the detail.
What is usually not covered is gradual damage. If a leak has been seeping slowly for months, or the cause is wear and tear on old fittings, insurers often exclude it because it was not a sudden, one-off event. That is the same rule everywhere in home insurance. Policies also treat trace and access, which is the cost of locating and getting to the source of a leak, in different ways, so check whether your wording includes it. Cover, limits and excesses vary between insurers, so read your policy wording rather than relying on a general rule.
Practical steps to protect your claim
Act quickly and keep evidence. As soon as you notice water coming through, get the source stopped, which usually means alerting the flat above so they can turn off their stopcock or the offending appliance. Report the leak to the neighbour and to your insurer promptly, because insurers expect you to limit further damage. Photograph and video everything before you start clearing up: the water coming in, the damaged ceiling, wet carpets, and each ruined item.
Keep receipts, keep damaged items where it is safe to do so, and write down dates and conversations. Solid evidence is what turns a slow, disputed claim into a quick one, and it matters even more if fault is contested between the two insurers. Our checklist on water damage claim evidence and our step-by-step on how to claim for water damage walk through exactly what to gather.
When a loss assessor can help
On a larger or contested claim, the numbers get big and the process gets stressful. It helps to know who works for whom. The insurer appoints a loss adjuster, whose job is to assess the claim on the insurer's behalf. A loss assessor is the opposite: an independent professional you can appoint to manage the claim for you, the policyholder, and to argue your side of the valuation. For high-value water damage, that balance can make a real difference.
