Aquariums work but can be dificult to keep the temps and humidity correctly. I use them in Washington state and keep them ok but I am in the process of building custom enclosures.

Another option would be a rack setup and I would look at Reptile Basics. Rich at RBI is a great guy and will gladly answer any questions you might have. I have 2 of his Vivarium T-stats and love them. RBI also has some great items such as hides and temp guns but I am not sure what shipping to the UK for such items would be
