Agree with some of the other comments.
In my limited experience, surveys are less useful than the opinion of a trusted builder.
The surveyors cover their backside. For instance:
There may or may not asbestos in the ceiling
They won't know if there's huge cracks under the wallpaper. There could be the biggest stress crack you've ever seen under the wallpaper and the survey wouldn't find it.
They won't poke around in the loft/attic.
They might not notice problems with support above windows. Minimum width etc..
You get the idea...
If/when its next time, I'll prob just get a minimal survey done assume I can find a good builder to conduct a survey of sorts...
