What counts as an unoccupied house?
The definition is stricter than most owners assume, and it is the insurer's definition that matters, not a common-sense one.
The consecutive days test
Most UK home insurance policies define a property as unoccupied once nobody has slept there for a stated number of consecutive nights, commonly 30, 45 or 60 depending on the insurer. Some policies use a stricter test for the winter months.
Visiting to collect post, water plants or check on the property does not reset the clock in most wordings. The test is usually about overnight occupancy, so read the definition in your own policy rather than relying on what is typical.
The Financial Ombudsman Service, which handles disputes between consumers and UK insurers, notes that most home policies use a 30 or 60 day limit and stop paying for certain types of damage once it is passed. Home insurance unoccupied clauses of 30, 45 and 60 days are all in use.
Unoccupied versus unfurnished
These are separate concepts and insurers price them differently. A furnished property between tenancies presents a different risk profile from a stripped, unfurnished property mid-renovation.
Some products cover one and not the other. If a property is both empty and unfurnished, check that the policy you are quoted actually contemplates that combination.
Insurers also distinguish between temporarily unoccupied, where the owner or tenants intend to return, and vacant, a property with no contents and no occupant in prospect. HomeLet, a landlord insurance provider, frames the difference in these terms, and vacant attracts the stricter conditions.
What happens to standard cover
Cover is rarely cancelled outright. More commonly it reduces to a restricted set of perils, often fire, lightning, explosion and aircraft, sometimes with theft and escape of water excluded entirely.
Escape of water is the exclusion that causes the most disputes, because an undetected leak in an empty house can run for weeks. That is precisely the scenario the restriction is designed to exclude.
Insurers shorten the restricted list to FLEA, or FLEEA where earthquake is included, because these perils are least affected by nobody being at home. A burst pipe in an empty house does far more damage than one found within an hour.
The notification duty
Insurers generally require you to notify them once you know a property will exceed the unoccupancy limit, and often before it does rather than after.
Failing to disclose is treated as a change in risk that was not declared. That can affect a claim even where the loss has nothing to do with the property being empty.
Under the Consumer Insurance (Disclosure and Representations) Act 2012, a consumer must take reasonable care not to misrepresent the risk. Telling the insurer the house is empty discharges that duty, and some insurers will extend the standard policy for a fee rather than requiring a separate product.
