A subsidence history does not make a home uninsurable, but it does take it off the standard market. Comparison sites and mainstream insurers ask whether the property has ever suffered subsidence, heave or landslip, and a yes answer usually ends the quote. Cover is still available from insurers who specialise in previously underpinned and subsidence-affected homes, usually arranged through a broker, and priced on the quality of the repair rather than the fact of the history.

Subsidence frightens insurers because it is expensive, slow to resolve, and prone to recurring in the same soil. But a properly investigated and repaired property can be a better risk than its neighbours, because its foundations have been assessed and often strengthened in a way most homes never are. The specialist market prices on that logic.

Why the mainstream market says no

Mass-market home insurance is priced on postcodes and averages. Any answer that needs a human underwriter to read a document breaks that model, so the quote engine declines rather than investigates. A subsidence history is one of those answers, along with prior flooding, non-standard construction and long unoccupancy.

A decline from a comparison site is not a verdict on the property. It is a statement that this distribution channel does not handle complexity.

What the specialist market wants to see

Documentation decides everything. The questions an underwriter will ask are broadly: what caused the movement, what investigation was done, what repair was carried out, when, and has the property been stable since.

The documents that answer them are the structural engineer’s report, any monitoring records, the completion certificate for underpinning or other repair, and a certificate of structural adequacy where one was issued. A homeowner who can produce those is asking a different question to one who can only say it was underpinned before we bought it.

What to expect on terms

Expect the insurer to price the risk individually rather than from a rate table, to apply a higher excess for subsidence claims than for other perils, and to want continuity: insurers take comfort from a property that has been continuously insured for subsidence since the repair. Breaking the chain of cover can make the next policy harder to place, which is a practical reason not to let cover lapse while shopping around.

When you sell, the buyer will face the same questions, so the file of repair documents carries real value at conveyancing.

Answer the questions exactly

The legal duty on a consumer is to take reasonable care not to make a misrepresentation to the insurer. Guessing the repair date, rounding the story down to it was minor movement, or staying silent about an episode the seller disclosed to you are the failures that surface at claim time, when the insurer investigates the history properly. Answer what is asked, precisely, with the documents in front of you.

Common questions

Can I get home insurance after subsidence?

Yes. Mainstream insurers and comparison sites usually decline, but specialist insurers cover previously underpinned and subsidence-affected homes, normally through a broker, priced on the evidence of investigation and repair.

Do I have to declare subsidence that happened before I owned the house?

If the insurer asks about the property’s history, the question covers the property, not just your period of ownership. Answer with what you know, including what was disclosed to you when you bought.

Does underpinning make a house harder or easier to insure?

Both, depending on paperwork. Underpinning with a completion certificate, engineer’s report and years of stability afterwards is a well-understood risk many specialists will take. Undocumented underpinning is the difficult case.

Will my excess be higher?

Usually, for the subsidence peril specifically. The rest of the policy typically carries normal excesses.

Why use a broker for this?

Because the insurers who take these risks mostly do not sell direct or through comparison sites, and because presenting the risk properly, with the right documents in the right order, changes the answer you get.
