What does wear and tear mean?
Wear and tear describes the gradual deterioration that happens to any building over time: materials age, sealants perish, mortar erodes, pipework corrodes and roof coverings become brittle. It is a normal part of owning a property rather than an unexpected event.
Most UK buildings insurance policies exclude wear and tear, gradual deterioration and lack of maintenance. The precise wording varies between insurers, so the definition in your own policy is the one that matters.
Why insurance policies distinguish sudden damage from deterioration
Insurance is built around insured perils — specific events such as storm, fire, escape of water or impact. The policy is designed to respond when one of those events causes damage that would not otherwise have happened. Deterioration, by contrast, is predictable and continuous, so it is generally treated as a maintenance cost for the property owner.
This distinction is why the question “what caused it?” matters so much in a disputed claim, and why insurers often instruct a loss adjuster or surveyor to comment on the condition of the damaged element before the incident.
Wear and tear in roof claims
Roof claims are a frequent flashpoint. An insurer may accept that severe weather occurred but conclude that the covering was already at the end of its serviceable life, that slates were nail-sick, or that flashings and mortar had deteriorated. In that situation it may argue that the weather revealed an existing problem rather than caused new damage.
Our guide to a rejected roof insurance claim looks at this in more detail, including roof age and inspection evidence.
Wear and tear and water damage
With water damage, the question is often whether a pipe or seal failed suddenly or leaked slowly over months. Staining, tide marks, decayed timber and long-term dampness readings can all be used to support a view that damage developed gradually. See our guide to water damage claims that have been rejected.
Gradual damage
Many policies contain a separate exclusion for gradually operating causes. It is worth checking whether the insurer is relying on wear and tear, gradual damage, or both, because the evidence relevant to each can differ.
Maintenance issues
Policies often include a condition requiring the property to be kept in a reasonable state of repair. Blocked gutters, defective flat-roof coverings and failed pointing are typical examples raised by insurers. Records of inspections, servicing and completed repairs can help show how the property has been looked after.
What evidence might help establish the cause?
- dated photographs from before and after the incident;
- invoices and reports from previous maintenance, servicing or repairs;
- a specialist report addressing causation, not just cost;
- weather data for the date of the incident, in storm-related claims;
- a clear timeline of when the damage appeared and how quickly it developed;
- survey reports from when the property was purchased.
What to do if you disagree with the insurer
Start by identifying exactly what the insurer says happened, then consider whether the technical evidence supports it. Where the disagreement is about causation, an independent report from a suitably qualified professional is often the most direct response. The general steps in our guide to a declined home insurance claim apply here too, including the insurer’s complaint process.
