Is your postcode in a subsidence cluster?
We map the UK postcode areas where shrink/swell clay, made ground or mining history have historically driven claims. Type yours below.
We score each UK postcode area against historic ABI claims data, British Geological Survey soil maps, and the locations of treated properties in our own work.
A higher risk score means the area sees more subsidence claims per thousand homes than the national baseline. It does not mean your specific property is moving.
If you're already seeing diagonal cracking, book a free survey. If you're not, but you're worried, Subcheck baselines your home for £495 and tells you whether anything's moving.
Depots in the North West, the Midlands and North London.
We operate a regional engineer model: equipment, vans and crews are based in three hubs — the North West, the Midlands, and North London — and we travel UK‑wide from there for surveys. Free on‑site assessments are available across England and Wales, typically within a week of your call.
We mainly cover Manchester and Greater Manchester, Yorkshire, Birmingham and the West Midlands, Bristol, Wales, London and Greater London. We're nationwide for everything else — get in touch if your area isn't listed.
How we fix subsidence in a single day.
- STEP 01
We drill
Small 16mm holes — about the size of a 5p piece — through the perimeter at calculated points.
- STEP 02
We inject
Proprietary structural resin is injected through the ports, expanding to re‑bear the soil column beneath your footing.
- STEP 03
It hardens
The resin reaches load‑bearing strength in around fifteen minutes — far faster than the 21–28 days concrete needs.
London clay is the single biggest driver of UK subsidence claims.
The South East of England — and London in particular — sits on deep beds of London clay. Clay shrinks dramatically when it dries out and swells back when it re‑hydrates. That seasonal shrink / swell cycle is the single biggest driver of subsidence claims in the country, particularly after dry summers. Resin treatment re‑bears that clay column without excavation.
