Mystery Moth

While down the yard at work this afternoon I spotted an interesting moth just sat on the side of the shed. I don't know what its ID is so decided to grab a couple of shots of it. So at the moment I don't know what type it is but have posted shots on a couple of sites hoping to find out its ID , if anyone has an idea please let me know 
Update I have had a positive ID on another site as to it ID a  mullein moth
