You will need to contact PN about this because it depends (AFAIK) on the status of the line when the previous tenants left. For instance, a family member of mine moved last year but it would have cost quite a bit to connect to Plusnet because the previous tenant took the number with them. Needless to say, they stayed with BT who gave them a new number and it was free.
More recently I enquired for one of my referrals as they are moving house soon and that came back as free connection because as the previous tenant had died the telephone had been stopped. Best to call in preferably early am as they are rather busy at the mo.
Re: Timing - usually once the line is connected it is 7 to 10 days for bb connection (well, it was, but stand to be corrected).
