Some sort of finch?

In my birdwatch hour I spotted a bird in my garden that I can't identify. It was very small and beige with a red beak. It looked finch-like. I've tried the bird identifier and cannot find any pictures that match.

We do get escaped birds in our area that are not native to the UK. Where we regularly walk our dog parakeets are common, for example. So now I'm wondering if I've seen a non-native small escaped something!

However, given how small it was I did wonder if it might be a juvenille of some sort.

 

Any suggestions appreciated!
