Sky only broadband

I have sky only broadband as I was previously O2 broadband only. Phone line is BT.My question is a reverse type as I am happy to stay with sky for broadband but want to use different phone provider than Bt or Sky. Anyone know of any other phone companies thatSky only broadband works with?
Many thanks.

Many! But first you need to check that Sky will allow you to change your phone provider to anyone other than themselves. I'm not saying they won't, but best to check before you go any further.

If I read that right, the phone line is already with BT

Its BT who control the line. Just want to know if I move to say Tesco or Primus who are cheaper than BT for line rental, will Sky broadband still work

Yes, but Sky make the rules for broadband customers, one of which, is forced Sky line rental if you take their broadband. You would need to contact them to see what they are prepared to do in your case.

They don't seem to be requiring that for those moved in due to them taking the customers over from Be/O2. The question though is how easy it will be to change underlying phone provider when Sky are essentially providing a different service for the ex O2/Be customers. I suspect though that it ought to be OK - but issues do happen and it could result in no BB.

I thought that Sky would honour existing contracts. Changes to Line provider may annul that.

AFAIK Sky didn't require O₂ customers to move from their current line and calls provider at the time of the broadband moving to the Sky network.
The OP would need to look at the terms and conditions to see what would occur when changing from that original provider to another one other than Sky.

I would imagine that a query call to Sky CS would possibly result in that the OP would have to go the route of full LLU i.e. MPF .......
of course I could be completely wrong in that assumption

The only condition regarding the phone line in O2 T&C's, and by succession in Sky's taking over of O2 existing contracts, is that the line must be a BTw WLR one.

Thanks for looking into the T&Cs on that. Is there an easy way to find out all the ISPs who use BT WLR ?
