UK Bat ID (1 Viewer)

Hi, can anyone ID this for me, seen flying in daylight in Suffolk yesterday
Seemed to be fairly large, wingspan possibly about the same as a Starling, though difficult to judge accurately,
certainly much bigger than the ones I see in my garden which I think are probably Pipistrelles

Any help appreciated, thanks

Although noctule is by far the commonest large bat I'm not sure it looks quite right. It's not particularly rufescent and the ears are quite long and tapered and the wings don't look narrow. Serotine seems a better fit but you might need to check a field guide to be sure. Can't remember if they differ in the shape of the tail membrane or not.
