I moved from BT to Sky 12 months ago. BT had pushed the price to £60-65 for services we rarely used. Moved to Sky, against my principles, for broadband only at £25/month. We haven't missed those services.
BT asked for the box to be returned. As I had an old one I sent that, the other box still functions as it did before and we use the smart TV for iPlayer.
The sport my wife is interested in can either be purchased for an annual Eurosport package at £79 or Amazon, I forget which package. So far all Mrs P has needed has been available on a one month £7.99 Eurosport pass.
We have Netflix and overall I'd say it offers more TV which I find entertaining than other services I've tried. Sadly that includes the BBC.
Broadband only plus buying services when needed is proving to be by far the cheapest option in this house.
