I don't know about shipping to UK. Bob is a dedicated business man id be surprised if he didn't. The Radiant Heat Panels your seeing are for homes and I would not use those as they arent made to be inside a Viv overheating...
I only know of Pro Products and Reptile basics here in the US. Email Bob, asking cant hurt.
