Hi,

We joined DST (Direct Save Telecom) they can get you a phone line for just over £100 installed and it's a 28 day contract. I can't remember the exact amount but they have rolling 28 day contracts. The other alternative is the Phone Co-op. They were the only 2 companies that I found that also install telephone lines. DST also do Broadband (that's what we have) with them.

Though you'd need to check with Tiscali if you need a BT landline as technically these options aren't.

The positives are we don't deal with BT!
