@JohnH5 maximum upload speeds vary according to the product you buy. With full fibre speeds are pretty reliable and vary according to the product you buy so to get 20Mb/s upload you would need to buy the FullFibre 100 or 150 products, for the faster tiers the upload increases until the Gigabit service can give you 100Mb/s upload.
With a service over copper the upload speed of the Superfast service is up to 20Mb/s but what you get depends on the length of the copper line. Openreach dont guarantee upload speeds so Sky cannot either. Speeds are to the hub if you have slower WiFi then that will limit the speed.
