How we usually approach subsidence insurance claim repairs
Carrying out the agreed repairs

Best for: Claims where the repair scope has been settled
Pricing the adjuster’s or engineer’s schedule
When the claim reaches the repair stage, we price the schedule of work line by line, at no charge to request. You or the adjuster can compare it against other prices. The figures follow the agreed scope, so nothing is quietly added or left out.
Best for: Homeowners asked to obtain quotes for an agreed scope

Is the ground in Greater London prone to subsidence?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.
How long does a subsidence claim take?
Many claims take several months to over a year, mostly because of investigations and monitoring. On clay, insurers often want readings across a summer and winter before agreeing a repair. The repairs themselves are usually much quicker once the scope is settled.
Will the insurer pay for underpinning?
Only if investigations show it is needed, which is less common than many people expect. Most subsidence claims are fixed by dealing with the cause, such as a drain or tree, and then repairing the cracks. The insurer’s engineer recommends the method.
