The loft hatch is in the bathroom and no drafts from there. The roof is a new roof and felted, there is one chimney that runs through one of the bedrooms upstairs but when that door is shut I still get the draft coming down the stairs, so I don't thinks it's that either. It'd doing my head in though
I did wonder if it was caused by hot air rising. It is a fair draft though and I'm not convinced warm air hitting cold air would that, but maybe it can.
Thanks for the reply, gives me a chance to add some more info. No rads upstairs on the landing, so that rules that out. No drafts from the cupboard under the stairs. No large gaps under the doors. See I said it was driving me crazy. Will try the wetting hand trick though, thanks.
