Thanks for the quick reply bunny!
I'm likely to need space for 3 for now until the finances pick up. I did consider a cable, i live in a HMO and didn't want to take a chance with them rejecting it based on that. A cabinet is fine for what i'm looking for.
Thanks for the link, i know they needed to be 7 lever or something like that and have two locks with different keys to them on your cabinet?
