For a tandem recovery you might be better looking for a local "man with van"* or courier company, because almost nothing else will have the space for one.
*I don't know if the "man with van" is a uniquely British thing or not, so I'll explain. It's basically like a cross between a handyman and a van rental; you hire the man for a few hours and he brings along a van, will load it and take it to where you want it. It's normally used for trash runs, delivering bulk items and so on. They are often available on fairly short notice and they'd be able to tell you over the phone if the van is long enough for a tandem or not.
