The standard tariff, which means you can stream TV shows and movies to two devices at the same time, was £7.99 but will now be £8.99.
The premium tariff, which lets you stream to four devices, will increase by £2 to £11.99.
The basic subscription currently costs users £5.99 and is the only one that will stay the same.
The price increases will be rolled out over the next few weeks to existing customers, while new members will pay the higher charges immediately.
Prices for the streaming service last went up in October 2017.
Netflix says that from time to time they have to increase the cost “to reflect the significant investments we’ve made in new TV shows and films.”
