Standard home insurance becomes invalid if your property is left unoccupied for more than 30-60 days — a fact most homeowners only discover when they try to claim. Whether your property is empty while you're travelling, between tenants, undergoing renovation, or in probate, you need specialist unoccupied home insurance to maintain cover. This guide explains when your standard policy fails, what specialist cover costs, and which providers to use in 2026.
Key Facts 2026
Standard insurance voids: typically after 30-60 days unoccupied | Specialist cover from: ~£100-400/year | Key risks in empty property: vandalism, burst pipes, squatters, fire | Probate properties: can remain empty 12-18 months
When Does Standard Home Insurance Stop Covering Empty Properties?
Most standard home insurance policies define a property as 'unoccupied' once it has been continuously empty for a set number of days — typically 30-60 days. Once this threshold is crossed without notifying your insurer, your policy can be voided or significantly restricted for claims arising during that period. Insurers class empty properties as substantially higher risk because: water leaks go undetected for longer and cause far more damage; the risk of vandalism, squatting, and burglary is higher when a property appears empty; fire risks are greater with undetected electrical faults; and liability risks are elevated. Inform your insurer before you reach their threshold — they may extend cover for an additional premium, or you may need to switch to specialist unoccupied insurance.

Frequently Asked Questions
How long can I leave my house empty UK?
Standard home insurance typically covers up to 30-60 days of continuous vacancy. Beyond this, cover is restricted or voided. If your property will be empty for longer, contact your insurer immediately. Some insurers will extend for an additional premium; most will require you to switch to a specialist unoccupied home insurance policy.
Does home insurance cover empty houses UK?
Standard home insurance includes a clause that voids or restricts cover after a specified unoccupied period — typically 30-60 days. Contact your insurer as soon as you know the property will be empty beyond this threshold. Some extend cover for a premium; others require a specialist unoccupied policy.
Do I need insurance during probate UK?
Yes — properties in probate can remain unoccupied for 12-18+ months while the estate is settled. Executors are legally responsible for maintaining adequate insurance on estate property. Standard home insurance won't cover long-term empty properties. Specialist probate property insurance is available from British Reserve Insurance and Adrian Flux.
Does unoccupied insurance cost more than standard UK?
Yes — specialist unoccupied insurance typically costs more than standard home insurance because empty properties are higher risk. However, the exact cost depends on property type, location, and how long it will be empty. For shorter unoccupied periods, some standard insurers will extend cover for a small additional premium, which may be cheaper than a full specialist policy.
