I thought the operation was, light and fan when switched on, when switched off, light goes out but the fan runs on for a time. But doesn't it come with instructions about wiring?Thanks and all and especially @pete01. As suggested. I removed the live from the fan side and everything now works correctly.
Are we saying the live on the feed side is required or is that superflous here too? I don't plan to change it now as it is working! Just interested to understand.
