Free-TV set-top box
If you want a basic digital TV service, with a one-off cost, get a Freeview (TV via your aerial) or Freesat (TV via satellite dish) box. If you don’t want to splash out on a new TV, a set-top box is the cheapest and simplest way to get digital channels.
Pay-TV set-top box
If you want a wider choice of TV channels, or access to premium movie and sports channels, then consider a digital TV package from the likes of BT, Sky, Talk Talk or Virgin Media. These paid-for services have a monthly subscription fee, but you can often save money on this by bundling your TV service with your home phone or broadband. The box is usually provided as part of service or for a small extra fee.
TV streaming (smart TV) set-top box
Some set-top boxes allow you to connect to the internet, via your broadband, to access catch-up TV, such as BBC iPlayer and ITV Player. This can turn an older TV into a smart TV at a fraction of the cost.
