In September, the Prime Video platform will release The Lord Of The Rings: The Rings Of Power series, which cost an estimated £750 million in rights and filming costs.

The Prime price increase is the service’s first since 2014.
It comes months after Netflix increased basic and standard plans by £1 a month, while its premium plan was pushed £2 higher, only 18 months after a previous increase.
