Which repair method suits a home in Hillingdon?
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
Betterment priced separately
Many homeowners take the chance to do extra work while trades are on site, such as redecorating whole rooms or upgrading finishes. That betterment sits outside the claim, so we price it as a separate written quote, keeping the claim work clear.
Best for: Extra work you choose beyond the agreed claim repair

Does the ground around Hillingdon cause cracking?
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.
What is betterment in a subsidence claim?
Betterment is any improvement beyond restoring the home to its condition before the damage, such as upgrading finishes or redecorating extra rooms. The insurer does not normally pay for it. We price betterment as a separate written quote, so it is clearly kept outside the claim.
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.
