Survey finding
Subsidence monitoring recommended in your survey
A monitoring recommendation doesn't confirm subsidence, but it does mean the movement picture isn't clear yet. This page explains what buyers should understand, what questions to ask, and how to approach the insurance and lending implications before exchange.

Finding
Subsidence monitoring
What this usually means
When a surveyor or structural engineer recommends subsidence monitoring, it means cracks or movement patterns are present but not yet clearly categorised as historic and stable or ongoing. Monitoring (often via crack gauges, tell-tales, or repeated measurement) over several months establishes whether the movement is seasonal, progressive, or stopped. This is a precautionary step, not an automatic verdict of active subsidence.
Why it matters
Insurance and lending decisions are heavily affected by subsidence. Buying before monitoring is complete means you may be inheriting an open question on insurability and condition. Some buyers negotiate a price reduction and proceed; others wait for a monitoring period to complete before committing.
Ask your surveyor
- Check:What crack or movement patterns have led to the monitoring recommendation, and how significant do they appear?
- Check:What monitoring period would you expect to be necessary, and what would the results need to show?
Ask the seller
- Check:Are you aware of any existing monitoring equipment (tell-tales, gauges) in the property, and do you have any readings or reports?
- Check:Has buildings insurance been claimed under a subsidence or movement section, and how does the current policy treat this?
Next steps
- •Speak to your insurance broker before exchange, disclosing the monitoring recommendation and any movement history.
- •Consider a structural engineer's view to categorise the movement before committing to purchase.
