Offering goodwill advice whilst inspecting under the FPA was a tricky issue.
Some punters would get confused and think we were 'telling' them to do it, whilst others would know their legal position that as long as they maintained their cert, they were in the clear and would adopt a "Am I bovvered?" approach..
There was a case where a hotelier (I think) acted on godwill advice believing it to be a requirement, made expensive AFD improvements which they later found was above the requirements in the fire cert and thereby unenforceable. This went to court and cost the FRS in compensation.
As a result, it was policy for IOs to always offer goodwill advice when requested during FPA visits, but to be very careful when offering unsolicited advice in case this confusion arose again.
