Tony Conder, from the Building Research Association, says councils have many restrictions governing moving.
In the past, houses have been moved, then left for a long period without being finished.
"You often have to sign a covenant to complete the house and that sort of thing," he says.
No organisations offer apackage of information on the process. Talk to the movers, talk to the council, find the restrictions.
Then seek advice from a professional designer, architect or draughtsman - someone with experience in the area.
And ask around to find a reputable company, he says.
His association has accredited advisers who may help and can also inspect the house for condition, suitability for relocation, and the amount of work needed.
Larger homes, which need to be cut into sections, could be damaged.
Architraves and skirting may need to be replaced - an expensive business if it is a historic house. Wiring could also be sliced through.
Careful checks are required.
Mr Conder also advises buyers to ask lawyers to check contracts with removal companies and do the usual title searches.
"Relocation is not really to be viewed as an easy alternative to building.
"I think there are too many traps in it.
"It's not a field for the amateur to get involved in," he says.
