Older homes often have character, charm, and a sense of identity that newer properties may lack. However, their age also makes them vulnerable to greater structural risk.
One of the most significant of these is subsidence. As buildings get older, foundations and materials can weaken, making movement in the ground more likely to cause damage. That’s why having the right home insurance subsidence cover is especially important for owners of older properties.
Subsidence occurs when the ground beneath a property sinks or shifts, causing the foundations to move. In older homes, traditional building methods and materials such as shallow foundations, clay bricks, and lime mortar make them more vulnerable to these changes, as many older construction materials behave differently over time compared to modern alternatives
Over time, factors like tree roots, leaking drains, or prolonged dry weather can further destabilise the ground. As a result, many older homes develop cracks in walls or floors, sticking doors, and other tell-tale signs of movement.
According to property experts, homes built before the 1950s are particularly prone to minor structural shifts, and while not all movement is serious, insurers may still need evidence that any historic movement has been investigated and resolved.
Most standard home insurance policies include subsidence cover, but only for properties with no unresolved or ongoing history of subsidence.
This section of the policy is designed to help with the cost of repairing damage caused by subsidence, ground heave, or landslip. It usually covers:
However, some policies exclude damage to outdoor structures such as fences, patios, or driveways. Insurers also apply a higher excess for home insurance covering subsidence, which can be upwards of £1,000 depending on the provider.
When applying for home insurance cover for subsidence, it’s essential to give full and accurate details about your property, including its age, construction type, and any previous movement or repairs. Non-disclosure of known issues could invalidate your policy or lead to a claim being declined.
Older properties that have been underpinned or have a history of movement are not automatically uninsurable, but insurers will need evidence that historical subsidence has been properly resolved and that the building remains stable.
Providing a structural engineer’s report or survey can strengthen your application and give insurers confidence that the risk is understood and managed.
Of course, you can’t change a property’s age. You can, however, take steps to lower the likelihood of future movement:
These simple measures can help reduce the risk of subsidence and demonstrate responsible property maintenance to insurers.
Owning a period or heritage home is a privilege that also brings added responsibility. Having the right home insurance subsidence cover keeps your property, and your investment, protected against one of the most common and costly structural issues.
