Garden Bird

Can you identify this garden bird from my description (UK)?

This bird visited the hanging peanut feeder in my garden today:-

Colour – Olive green all over (brown-ish yellow-y green)
Size – Slightly longer and thinner than a house sparrow
Short tail, brown legs & beak.

Any ideas what it is?

It sounds like a greenfinch.
