Bathroom refit & moving tank

[Trickytricky]

I've just had someone come round to quote for a new bathroom and mentioned that I'd like the hot water tank upgraded and moved into the loft space. The guy said that they can't do that and only fit the bathroom. He said I'd have to speak to a heating engineer about moving the hot water tank etc. Is this normal? I would expect a bathroom company to be able to move the tank and deal with the heating elements.

Any one?
