# Subsidence Survey Cost > Subsidence survey cost explained: what a structural engineer's report covers, why monitoring, drainage and root work add to it, and free quotes from local engineers. ## Key facts - A domestic structural engineer's visual inspection and written report on cracking is typically quoted at £300–£800 in 2026, varying by region, property size and report depth. - Level monitoring for suspected subsidence is normally read across a full seasonal cycle, so a diagnosis takes months rather than days. - Subsidence investigation and any resulting works are normally handled as a buildings insurance claim subject to the policy excess, not as work the homeowner commissions blind. ## Key pages - [What does a subsidence survey cost?](https://subsidencesurveycost.co.uk/): the main tool, answer above the fold. - [Structural engineer report cost: the subsidence survey fee in the UK](https://subsidencesurveycost.co.uk/structural-engineer-report-cost/): A domestic structural engineer's inspection and report is typically £300–£800 in 2026 quotes.

Methodology: Compiled from the standard sequence of a UK domestic subsidence investigation: initial structural inspection, a monitoring period, then targeted investigation of drainage and vegetation before any repair scheme is designed. It is a cost-driver table rather than a price list, because the only stage with a reliably typical market price is the initial inspection and report; everything after it is scoped to the individual building.
