Yes. You should be auto-enrolled (I think). It all gets played out via the 'My Sky' app.
They offer all sorts of stuff - some you have to enter a ballot for, some you get anyway.
The Sky Q stuff cost me £0. Mind you, they've had enough off me over the years!!
Upgraded just before Christmas. Main box & 3 miniboxes, all free under the Sky Black VIP scheme.
Really pleased, no problems with picture or coverage. The mesh WiFi works really well.
