Rather tame mouse, let me get quite close before running off.
No interactions present.
There is a yellow smudge on the chest so this could well be a yellow-necked mouse, but it could be just that, a small smudge rather than a solid band across the chest; hence it could equally be a wood mouse or even a hybrid?
I'm afraid it must go down as Apodemus sp. based on the photos.
Cute photos though!

Thanks for this. I did wonder about yellow-necked mouse but didn't get quite a good enough look at it. When I looked it up later, I read that yellow-necked have slightly larger ears, but I couldn't spot any difference in the pictures.
Ignore what you read about these two mice other than yellow-necked mice have a broad yellow band (grey-yellow in juveniles but otherwise the same) running across their chest which is continuous from shoulder to shoulder. Wood mice can have a yellow smudge or spot in the centre of the chest but it never forms a continuous band.
There are other ways, ears included, but you are talking one or two mm, no more, so it is impossible to tell in the field; you need to have them in the hand and measure very accurately.
Then there are the possible hybrids . . . !
