Sky customers who are currently on either "legacy products" – and benefitting from a lower price – will see their bills increase to bring them into line with Sky's current pricing structure.
Sky says the changes "reflect its ongoing investment in on screen line up, technology and customer service".
A spokesperson for Sky said: "There are no changes to our existing headline pricing for Sky TV bundles and the vast majority of customers will see no change at all to the cost of their TV package.
"We are also keeping line rental prices at their current level for customers who only take a landline from us."
The last time Sky raised prices was in June 2016, when it bumped up television costs.
Sky TV customers' bills increased by an average of £2 to £3 a month.
Those who subscribed to the satellite broadcaster's premier package – dubbed The Complete – saw a jump of £4.25, taking the total cost to an eye-watering £80 a month.
Meanwhile, Sky increased line rental prices back in December 2015, when monthly bills rose from £16.40 to £17.40.
Those who are not happy with the latest price rise have a few options.
