Rabbit double hutch advice uk only please?

I know the question says UK only, but I have not saw any other answers and I have to put my 10 cents in here please. I am a rabbit breeder in the U.S. I build my own cages. I buy the wire and clamps and it is much cheaper and I can make the cages the exact shape and size to fit my needs. I know there are a couple of online places that sell wire. Maby if you can't find a cage to fit you and your price, you can look online? Just a suggestion.
