Can anyone ID this tree please?

We have some fruit trees at the back of our garden, this one was hidden in the corner.... Haven't a clue what it is.
At first I thought it might be another fruit tree as it's beside a plum and two apple trees but no blossom on it. It does get lots of red berries in the autumn though? Help!

Will look in my tree book

Is it crab apple

Or maybe a type of hawthorn also called crataegus

Looks like a Cotoneaster

Yes - I Googled cotoneaster and it's a willow leaf variety. Lots of red berries and definitely a tree shape and not a shrub.
Thank you both
