Charles - Broad-bordered Yellow Underwing looks a definite possibility although a lot more speckled than this suspect.
Trev - can't find Large Wainscot or White Colon on ukleps - do they have other names?
I emailed Reg at ukleps but I know he's not keen on ID queries and no reply so far. Can anyone get me an introduction?
