I don't think there are any.
Thumpers have closed a long time ago, the willows deal mainly with large animals and the New Arc has become a sanctuary.
There may be a couple of small ones, but be careful as they are not always very knowledgable.
You could try Runky animal rescue, I know nothing about them, other than they exist.
I know fairly beloved rescue in Glasgow Rehome up here, Alvin's mum just rehomed 2 from there.
