I believe BT forces some people to pay for the new line installation charge even if previous tenants already have a phone line with BT before you move in. I live in a flat that previously had 2 tenants in 3 years and I do not believe none of them had the phone line installed. Also a friend also just moved in to the same building as me and he also had to pay the new connection phone charge even though he saw the telephone being used and a router used by the previous tenant when he view his flat.
Rubbish, if there is a stopped line you do not pay to start it up again, however if the line was "ceased" by the outgoing tennant you have to pay to install it again as the equipment would have been removed, u may see a socket but on the other side of it the equipment will have been removed back to the exchange.
Its not BT's fault if someone who moves out requests a cease so you shouldnt expect to get it for free
