This song is new in the area, and the bird is not visible as it is high in the trees. It makes 8 shrill chirps.

I agree with Tony about it being possibly a Tit member. I would go for Blue Tit if compared to this sound - start at the 46 second mark and blue tit.

In reply to TeeJay:
Thanks for the further info. Probably not anything too exotic then. There's a saying amongst birders that if there's a call you don't recognise it's probably a Great Tit as they have such a variety of songs and calls.
I found one Great Tit song on xeno-canto which is not too dissimilar to yours.

What do you think - could it be this? Great Tits are very vocal at the moment. Or maybe Hazy is right. Best I can come up with I'm afraid.
