This isn't a micro that's going to excite anyone except an already converted die-hard micro enthusiast - it's a tiny grey speck, possibly the most insignificant-looking moth you're ever likely to see.
Anyway, for such an easily overlooked micro there are quite a good number of records in Norfolk. It had elluded me until I moved to North Elmham last year when I had six in my trap during September. The past week has brounght three more. Judging from other people's photos they can often be a bit more distinctive with a more contrasting black-and-white pattern, but all mine have been grey like these. Not the easiest ID to be sure of but I did check these under the microscope (not easy then either!). All were males - if the two individuals illustrated in MOGBI are anything to go by that might explain why so dull - the female pictured in MOGBI is far better marked than the male.
