Pets At Home have a Slavic Ruffy (rat) cage. The low one is best to prevent falls/injury. It comes with a rat tube. It has narrow bar spacing so could be used for a Syrian or dwarf hamster.

There are other rat cages available, but they are a bit too tall.
Zoo plus website is probably better as they have the Alaska, Barney and Alexander cage. Which are better value for money.
