Hi Alex
Warm welcome to Birdforum! Glad you are keeping those feeders topped up in this cold weather.
Your birds are House Sparrows.
I will link some images for you.
House sparrows are noisy and gregarious, often going around together in small flocks. Find out more abut house sparrows

Note the female does not have a big white patch on her wing compared to female Chaffinch
This is a quick and easy way to tell them apart in the first instance.
The chaffinch is the UK's second commonest breeding bird, and is arguably the most colourful of the UK's finches. Find out more

Don’t forget there is an opportunity to count your garden birds this weekend and record the results if you have time for one hour for the Big Garden Birdwatch - there is a garden bird guide on the form or you can post photos on the ID forum and other members will help you 🙂
The dates are in! Join us for Big Garden Birdwatch 29 - 31 January 2021. Registration opens 9 December 2020! Find out more.
