How to Sell a House With Subsidence or Structural Movement (UK Guide)

The short answer

You can sell a house with subsidence, but the paperwork decides the price and speed. Historic movement that was properly repaired is often manageable. Active or unexplained movement usually scares off mortgage buyers, so a cash buyer or auction becomes more likely.

Subsidence, heave and settlement: what is the difference?

• Subsidence — the ground under the foundations moves down. Common causes are shrinking clay soil in dry summers, tree roots drawing moisture, and leaking or collapsed drains washing soil away.
• Heave — the ground swells upwards, often after trees are removed from clay soil.
• Settlement — normal, early movement in a new building as it beds in. It is usually not progressive.

Former mining areas, including parts of South Wales, the Midlands and the North, can also have coal-mining-related ground movement. See our guide on coal mining subsidence in South Wales.

Signs a surveyor will look for

• Diagonal cracks wider than about 3mm, especially near doors and windows.
• Doors and windows that stick or no longer fit their frames.
• Rippling wallpaper, gaps between walls and ceilings, or sloping floors.
• Cracks that reopen after redecoration.

Why subsidence makes a sale harder

• Lenders may refuse, retain part of the loan or ask for a structural engineer report.
• Insurers may raise premiums or excesses, or refuse new cover. Staying with the insurer that handled the claim can help.
• Buyers worry about future costs, and survey findings often lead to renegotiation late in the sale.

Documents that make your house easier to sell

• Structural engineer report explaining the cause and whether movement is ongoing.
• Monitoring results, if crack or level monitoring was carried out.
• Certificate of structural adequacy after repairs.
• Insurance claim records, including works carried out and any guarantees for underpinning.
• Drain survey and repair records if drains were the cause.

The cost of a survey is small compared with a buyer pulling out late in the process.

Your selling options

| Route | Best for | Main risk | |---|---|---| | Estate agent | Repaired, documented historic movement | Buyer's lender refuses after survey | | Auction | Homes needing major work | Fees, deposit deadlines and uncertain price | | Cash buyer | Active movement, missing paperwork or a deadline | Price reflects repair risk |

What if the movement is still active?

Make an insurance claim if you are covered — investigation and monitoring can take months. If you cannot wait, a cash buyer may buy before the claim is finished. Talk to your insurer and solicitor before agreeing a sale, because a sale can affect an open claim.
