Back on topic, BT haven't given you an offer at all, really.
When I was with BT I managed to negotiate:
£15 a month for Infinity 2
£5 for Unlimited Anytime Calls
£5 for Entertainment Plus & HD Extra
In addition to the standard £17.99/£18.99 line rental. I prepaid that with Line Rental Saver for the time I was with them, anyway. So you haven't been offered anything any good at all - you should be looking at getting what I got above, less the anytime calls (as weekend calls are included in all packages). Meaning aiming for £38.99 or so.
PlusNet is actually owned by BT nowadays, but their customer support and operations are separate. That said, PlusNet use the BT Wholesale network to get the traffic to and from the exchange (as do many other ISPs), so switching from one to another should incur little to no disruption depending on the way it is done, maximum 30 mins or so. Of course they might mess it up, but that's always a possibilty.
PlusNet support has a reputation for being really slow to get through to, especially at peak times - and they still don't support IPv6 which is ridiculous given how many other major providers do and how long it's been around (since 2000 or so). They seem to have the same "ask again in 6 months, every 6 months" attitude that pervades most of BT.
All that said, if you threaten to leave BT, or actually initiate the process by ordering a migration with PlusNet, you'll probably be given a retentions offer much closer to what I had. If you don't already have a Smart Hub modem-router (Home Hub 6, came out last summer) then you should also negotiate to get that thrown in for free, or at most the cost of postage.
With any of these major providers the customer service, support and technical stuff is never going to be very good, but generally in terms of new customer pricing you get what you pay for in the ISP world (BT excepted - their standard pricing is regulated by Ofcom). That's why I'm with AAISP now...
Any further questions, don't hesitate to ask me.
