The 30-day rule: how Greek home insurance quietly fails when you're abroad.

An overseas owner files a claim. Burst pipe in the kitchen, ceiling collapsed in the apartment below, repair bill in five figures. The insurance company says no.

Not because the policy excludes water damage. It doesn't. The policy excludes water damage under one specific condition — and that condition appears in almost every Greek home-insurance contract, in language so quiet that most owners never see it until the day it costs them.

The clause

Greek home-insurance policies — like most policies in the EU and US — contain what's known as a vacancy clause or unoccupancy clause. The wording varies between insurers, but the structure is consistent. It says something like: cover is restricted or excluded after the insured property has been unattended for a continuous period of [N] days.

In Greek policies, that N is typically 30 days. Some insurers extend it to 60. A handful of premium policies go to 90 days with an additional rider. The 30-day baseline is the most common starting point.

"Unattended" doesn't mean "uninhabited." It doesn't mean the property is in disrepair, or that nobody owns it. It means nobody has been physically present at the property to a degree the insurer considers meaningful. The exact threshold is rarely defined in the policy itself — which is where the trouble starts.

What gets excluded

The standard exclusions during a vacancy period look like this:

• Water damage from internal sources. Burst pipes, slow leaks, washing machine hoses, water heater failures. This is the big one, and it accounts for the majority of refused claims on vacant properties.
• Theft and vandalism. If your alarm wasn't armed or there's no evidence of forced entry, the insurer may apply the vacancy clause as a second exclusion on top of the standard burden of proof.
• Glass breakage, especially in conjunction with weather events.
• Damage from frozen pipes (less common in Greece, but real for properties at altitude or with poor heating).
• Some natural-cause damage where the insurer can argue earlier intervention would have limited the loss.

What stays covered, typically: fire, explosion, direct storm damage, and most third-party liability. Even there, though, the insurer can argue that vacancy contributed to the severity of the loss.

Why insurers love this clause

The honest answer: vacant properties have a different risk profile, and the data backs it up. A small leak in an occupied apartment is noticed within hours. The same leak in a vacant apartment runs for weeks. By the time someone arrives, the floor below is unliveable.

Insurers price policies for the average property risk. The vacancy clause is what protects them from paying out at occupied-property rates for claims that should have been priced at vacant-property rates. From their perspective, it's not a trick — it's a calibration.

From the owner's perspective, it can still feel like a trick, because the clause is almost never explained at the point of sale.

The documentation that beats it

The vacancy clause is not absolute. The standard out — and the standard counter-argument when a claim is contested — is to demonstrate that the property was not, in fact, unattended in any meaningful sense.

That demonstration takes a specific form. Insurers generally accept the following as evidence of attendance:

• Timestamped visit logs. A record of someone entering the property on dated, regular intervals.
• Photographic evidence. Photos with embedded EXIF metadata showing the date, time, and ideally GPS location.
• Written reports. Notes describing what was inspected on each visit. The more specific, the better — "tap flushed in kitchen, no leaks, no moisture" beats "everything looked fine."
• A keyholder agreement. A written contract with whoever holds the key, naming them, their qualifications, and the agreed visit frequency.

If you have all four of these, you have a strong argument that the property was not unattended in the spirit of the clause, regardless of whether you personally were present. Most refused claims get refused because the owner relied on a neighbour, a relative, or a cleaner who left no documentation. The damage was probably caught — but nobody can prove it.

What home-watch actually does for your insurance

This is the unglamorous core of what a professional home-watch service is. The trained inspections, the photo reports, the geolocated timestamps, the formal visit logs — they all exist primarily because they're the only thing that holds up when an insurer questions a claim.

It's not a guarantee. No insurer pre-approves home-watch records as automatically satisfying their vacancy clause. But in practice, when a claim is contested and you can produce a year of monthly inspection reports with photos, the conversation moves from "we're denying" to "we're investigating," and from "we're investigating" to "we're paying."

What to do this week, even if you're not a member

Three quick wins, regardless of whether you ever use a home-watch service:

1. Read your policy. Specifically the section labelled "exclusions" or "general conditions." Search for the words vacant, unoccupied, unattended, or uninhabited. Note the threshold (30 / 60 / 90 days) and what triggers it.
2. Ask your broker for a vacancy extension. Many insurers will sell you a rider that extends the threshold or removes specific exclusions during longer absences. The cost is usually modest — €40 to €120 a year — and it pays for itself with a single covered claim.
3. Document anyone you currently rely on. If your sister-in-law checks the apartment monthly, write down the dates she went, ideally with photos she sends you. The legal weight of this is much higher than most people realise. Even a casual WhatsApp paper trail is better than nothing.

The 30-day rule is real, it's quietly invalidating tens of thousands of policies right now, and most owners don't know it exists until they file a claim. Now you do.
