Probably dumb question but is this a house sparrow? Slimbridge UK (1 Viewer)

I took this photo because I couldn't see what the bird was at it was too far away. It looked about large sparrow/small bullfinch in size. Even correcting for exposure, it seems unusually light coloured on the front and the pattern of black and white on the face doesn't seem to match anything I'm familiar with. In desperation I first thought it could be a great tit, but there's no hint of yellow even if you ramp the saturation up to maximum. Someone sitting next to me thought it was a reed bunting, but I've seen zillions of reed buntings (albeit never from that angle) and it doesn't look right to me. House sparrow was my best guess but the head shape seem off, and you can see in some of the photos that as well as the white sides of its head, it also has a white patch at the base of the beak (looks like, to me), as well as the black stripe down the front.

I'm probably being really stupid but I don't know what it is.

these are all my photos, the 'best' first, then I will post the others in a second post in case they add info.

thank you in advance all!

and finally...

I believe it looks okay for a reed bunting, but I'd like to see what an expert thinks

They vary such a lot, but the white area on the side of the head looked large to me. I can certainly believe it. As you say, expert opinions welcome!

thanks

I thought of the Reed Bunting too, though not sure.

Male Reed Bunting.

Maybe it is an escaped exotic, zebra finch or something like that

Thanks all, I guess it's just a reed bunting + my pants photo!
