Is there any UK bird that sounds like a chipping sparrow?

Twice today, I have heard a very unusual trilling song - almost more like an insect.  Both times it came from the same area of hedge( in rural Devon), and when I googled ‘trilling bird song’, chipping sparrow is what it sounds like.  Unfortunately no recording as I was without my phone, nor could I see it very well, but it seemed to be sort of sparrow sized.

(Apologies if this has already been posted, but something odd happened first time I tried)
