I tried to find some small animal rescues near you but couldn't find any.
A lot of larger rescues get hamsters in from time to time though.
I know that on my local
Gumtree website there is often hamsters looking for new homes. Also, you could look on
Preloved. Both websites have hamsters on them a lot. Some would claim this isn't rescuing, but it's the closest thing to if there are no rescues near you. Although, on those websites there are often baby hamsters for sale, which are being sold by (usually, but not always) irresponsible breeders, so you might want to ignore those...
