I signed up with BT through Quidco, getting £120 cashback, plus the BT offers on the fibre broadband service and a prepaid card. Between the three, it makes the service alright value, but I wouldn't (and won't be) using the service at standard pricing.

The service itself has been reliable enough, though it does disconnect without warning during the daytime when they decide they need to do maintenance on the cabinet outside - (I can see it from my window.) Thankfully, it's only been three times in the year I've been with them, but it's extremely frustrating to have maintenance performed during the day without being told about it.

They did also upgrade my service from the 40/10 package I'd ordered to the 55/10 service at no extra cost to me, so I can't complain there at all.
