It depends on the circumstances, ie the nature of the problem, whether a written report is needed and when the work is likely to go ahead. Our local office will be able to advise you on this - you can contact them free on 0800 789 500. We would normally charge on pre-purchase surveys and for wall tie inspections because they take longer and require access facilities to be arranged. If the work goes ahead, any survey fee charged is generally deducted from the repair cost..
