Leakage from neighbours: who reports the damage and who pays?

Quick answer: who pays and who reports

When water leaks from a neighbour’s home into yours, the first step in the Dutch insurance system is to report the claim to your own buildings (opstal) or contents (inboedel) insurer. They pay out the damage, and if the neighbour is found liable, the insurer will later try to recover the costs from the neighbour’s liability insurance. This arrangement prevents you from having to fight a legal battle with your neighbour right away. However, there are important exceptions, and you must act quickly to protect your right to compensation. Water damage claims usually require notification within 24 to 48 hours of discovery, and you need to carefully document the cause and extent of the damage.

When does this situation occur?

Leaks from neighbours can happen in all types of housing. In an apartment complex, water from the unit above may seep through the ceiling or walls. In a terraced house (rijtjeshuis), moisture can migrate through a shared wall, for example from a leaking bathroom or a burst kitchen pipe. Split-level homes (boven- en benedenwoning) often face similar issues when a washing machine or boiler on the upper floor malfunctions. Even in a detached house, your neighbour’s blocked rainwater drain could send water towards your foundation or garden shed. In all these cases, the key question is: who bears the cost?

• Apartment: water leaking through the ceiling or walls from the unit above.
• Terraced house: moisture penetrating through a shared wall.
• Split-level home: damage caused by faulty appliances in the other unit.
• Detached house: rainwater run-off from a neighbour’s blocked drain.

How your own policy and liability work together

The Dutch non-life insurance system is designed so that you claim your own damage under your own policy first. Buildings insurance (opstalverzekering) covers the structure of your home — walls, floors, ceilings, built-in kitchen — while contents insurance (inboedelverzekering) pays for your belongings like furniture, floor coverings and electronics. For water damage coming from outside — including a neighbour’s leak — most policies provide cover, as long as there are no exclusions such as gradual neglect or long-term seepage. Importantly, once your insurer pays the claim, it can seek recovery (regres) from the neighbour’s liability insurance if the neighbour was at fault.

Your neighbour’s personal liability insurance (AVP) only steps in when the damage results from a mistake or negligence. A sudden, unforeseen pipe burst is generally not considered blameworthy, meaning the neighbour’s liability insurance won’t pay. If, however, the neighbour ignored a leak for months or carried out a botched DIY plumbing job, their insurer might cover the damage. Proving fault is often complex, so it’s wise to rely mainly on your own insurance.

Step-by-step: what to do when your neighbour’s leak affects you

What is often not covered or misunderstood

A persistent myth is that your neighbour’s liability insurance automatically covers all damage. In reality, the AVP only pays when the neighbour is legally at fault — for example, through neglected maintenance or a clumsy repair. Without such fault, the neighbour is not obliged to pay, and you bear your own loss. Fortunately, your own buildings or contents policy usually covers these unforeseen events.

Also, damage resulting from neglected maintenance is often excluded on both your policy and your neighbour’s. If you or your neighbour ignored a dripping tap for months, the insurer may argue the damage was not sudden and reject the claim. Moreover, you are obliged to prevent further damage; if you fail to turn off the water while it continues to flow, the extra damage may not be compensated. Additionally, your insurer usually applies an excess (eigen risico), typically between €100 and €500. This deductible is only refunded if the insurer fully recovers the costs from the neighbour.

Common mistakes when dealing with a neighbour’s leak

• Reporting too late: waiting weeks can lead your insurer to reject the claim, arguing the damage could have been mitigated.
• Assuming the neighbour will pay everything: never agree to a direct settlement without your insurer’s assessment. The neighbour’s liability insurance rarely pays for pure technical failure.
• Not photographing the cause: once the plumber repairs the leak, the evidence is gone. Capture the source before work starts.
• DIY electrical work in wet areas: this is dangerous and may cause extra damage that your insurer will not cover. Call a certified professional.
• Overlooking the VvE: in apartments, the ceiling or a structural wall may fall under the collective buildings policy. Always notify the VvE as well.

When it makes sense to consult an adviser

For a straightforward leak — a damp patch on the ceiling, a broken coupling — your insurer usually processes the claim smoothly. The policy wording and the loss adjuster’s report determine the outcome. But if the damage is extensive, the insurer’s payout seems too low, or the neighbour disputes liability, it may be wise to get an independent second opinion. An adviser who reviews your entire insurance portfolio can check whether the settlement is fair, whether other policies might apply, and whether you are underinsured or paying double premiums.

If you also want to carefully compare your contents insurance, review your buildings insurance or audit your liability cover, talking to an adviser can give you clarity. That way, a future leak will cause far less financial stress.
