Report on the "Which?" investigation into surveyor complaints. "Which?" sent out 232 questionnaires to people who had experienced problems with domestic surveys they had paid for. The findings were based on 80 responses. The most popular cause for complaint was the surveyor's failure to spot a defect. Other complaints related to 'grey areas' such as gas and electricity supplies, and people often had high expectations that went beyond the scope of their survey. The investigation also revealed that people were confused about choosing the right kind of survey and felt that the final report was too vague and contained too many caveats. "Which?" also questioned respondants about complaint handling including surveyors' responses to complaints, the RICS complaints system, and going to court. In response to the "Which?" report, RICS has produced a free leaflet "Understanding property surveys"
