New Customer offers for Sky Broadband as existing TV customer

Sp363

seen a deal via quidco which gives an equivalent price for ultrafast plus (500mb) at £24.78. Would I be able to access this even as an existing Sky TV customer?
My broadband is BT currently (locked in original due to new build house hence why tv and broadband out of sync) who have offered me £34.99 for 500mb on 2yr contract.

BT should also be able to tell you a price to terminate your contract - you then need to work o9ut if that still works out cheaper...

My contract runs out at the end of the month so no issues with the termination part. My main question was would I still be able to get the deal even though I'm technically a sky customer but only for TV?
can't seem to find anything about this online, obviously the call centre people don't know/don't want you to switch
