I am currently renovating and want to get VM BB. The connection never had BB (just TV) before and is quite old so probably needs a visit out by the techie to get iot sorted. Can I get them out while renovating and not actually start the contract till it's ready for occupation ? Any problems I can envisage ? It would be handy to get it done while bulder in situ as I may not be able to be there during the day later down the line.
