Would say 2 hours in the property is waaaay longer than needed - especially given how much of the reports seem to be copy-paste arse covering (apologies to good surveyors).
Perhaps they want to use the wifi there to write and send you the report in that time too..!
these are the main sections in the reports (NB. this can vary depending on property type, so list not necessarily exhaustive), each has about 20-150 words specifically about the structure condition.
For what's it's worth, the first one were all 2s and the second all 3s (no 1s for me..!)
What level is the survey? Homebuyers report?
Banks' surveys appear to essentially be 'is the house standing, does it have a bathroom and a kitchen that can be used'.
