I know that strictly speaking we should err on the side of caution because there is a record in north lincs on NBN, but I'm in East Yorks and have not heard of any records here or in North Yorks so on this occasion I'm more inclined to agree with your original ID of wood mouse.
However I'll be interested to see what Graham Banwell thinks when he looks at this one as he's done lots of surveys in that part of the world.
