Virgin Media customers will see prices go up by an average of 5.1 per cent later this year.
The telecoms company is hiking prices by between £1 and £3.49 per month in November.
Customers are being contacted about the changes and will be given 30 days after being notified to switch to another provider without penalty if they are unwilling to pay the revised rates.
The latest round of hikes follows previous rise in February, as well as a separate price rise in June for Virgin Media customers who are subscribed to Sky channels.
Gregor McNeil, Managing Director of Virgin Media's Consumer Division, commented: "We do everything we can to keep prices competitive while striking a balance with investing in more of what our customers want."
He added that Virgin Media offers more to customers than rival firms, including faster broadband and an upgraded TV service with a wider choice of box sets.
Furthermore, Mr McNeil said it is "the only place where you can watch all the live footballing action from both Sky and BT Sport in a single package".
