Possibly Epinotia immundana.
I think it's Epinotia nisella - saw one a couple of days ago.
I think you're right George. According to Hants Moths immundana has a wing span of 12-15mm and nisella 12-17mm. My moth was 16mm. There's also an image of nisella with a similar orange dorsal blotch. Variable little blighters ain't they! Thanks both, much appreciated.
Oops, meant to say aren't they!
