Typically, UHD 4K video will require a minimum of 25Mbit/s, however, some providers are encoding their video streams in different ways (e.g. using Variable bit rate as apposed to constant bit rate) meaning that lower speeds are required - perhaps around 17Mbit/s. (in 2018) Netflix 4K UHD tends to be around 17Mbit/s, other services, such as BBC, Amazon etc. may well be higher, even up to 35Mbit/s.
