If you are switching provider you can get Virgin Media Cable Broadband (size M) as well (no quidco) and its same price £10 pm (earlier post for VM ADSL) with first month free!!!
Just call their sales team on 0800 9535353 inquiring about this deal. If you go for size L package (£17) you can get free wireless router as part of the promotion posted earlier.
On top of this you could get to trash BT line (savings of £11) and take up vonage (broadband telephony) which gives you a UK number with following plans
Unlimited calling to UK & Ireland £5.99
Unlimited calling to 15 countries £7.99
Unlimited calling to 25 countries £9.99
The voice quality is crystal clear and only takes 32 - 90kbps (max) bandwidth.
I was previously paying £14.99 (virgin.net broadband) + £11 (BT Line rental) + £5 (Sky Talk Unlimited). A whopping total of 30.99 which has now been bought down to 17.99 which is a good 42% saving!!!
