From first photo to finished repair

Loss adjuster and engineer
The insurer usually appoints a loss adjuster, who visits and may bring in an engineer. They record the damage, ask about its history and arrange investigations such as a CCTV drain survey, trial pits and a tree survey.
Mitigation and monitoring
The identified cause is dealt with, perhaps a drain repair or tree work, and the house may be monitored for several months, sometimes up to 12, to confirm it has stabilised before repairs are agreed.
Schedule of repairs
The adjuster or engineer issues a schedule of the work needed. We can price to your loss adjuster’s or engineer’s schedule, and confirm a fixed price in writing, with any betterment shown as a separate quote.

Methods for subsidence insurance claim repairs

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

Carrying out the agreed repairs

Once the scope is agreed and you instruct us, we carry out the repair, which is often crack stitching, repointing, replastering and redecoration, and sometimes drain or foundation work. We deal with building control where the work needs it and keep the adjuster informed.

Best for: Claims where the repair scope has been settled

Do you need approval for subsidence insurance claim repairs in England?

Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.

Frequently asked questions

Does the ground around Croydon 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. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.

How much will subsidence insurance claim repairs cost in Greater London?

The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

What if my subsidence claim is declined?

Ask the insurer for the reasons in writing and check them against your policy wording. You can complain to the insurer and then, if unresolved, go to the Financial Ombudsman Service. If you decide to repair privately, we can give a no-obligation written quote.

Should I repair cracks before claiming?

No, tell your insurer before permanent repairs start. Early repairs can hide evidence the adjuster needs and may affect your claim. Take dated photos, and if a crack is letting in water, ask the insurer about a temporary weatherproofing measure.
