IMO house surveys in the UK are a joke and surveyors are a wildly overpaid joke profession. A typical survey, even a "full" survey, is 90% disclaimer. The remaining 10% is often obvious to anyone with working eyeballs.

If you want a useful opinion hire an experienced builder to assess the property - perhaps under the pretext of costing possible renovations.

When I was selling my mother's house a few years ago, a builder who viewed it instantly spotted all the problems that professional surveyors either missed or couldn't be bothered to mention.
