Millions of BT Sport customers are to see their bills rise next month in a latest round of price hikes.
Households will see prices rise by up to £4 a month in the changes due to kick in ahead of the new Premier League season.
The increase will take effect from 28 July, with BT emailing customers with the details this week.
BT TV is only available to BT broadband customers, or as an add-on via other providers such as Sky. BT broadband customers can also opt to pay for a BT Sport app.
The firm said the rises will be between £1 and £4 a month.
BT explained those on the Classic, Essential, Sport Starter, Entertainment and Entertainment Plus packages will see £1 rises - equivalent to £12 a year - while those on the Max plan will see a £4 a month rise - equivalent to £48 a year.
Anyone with the BT Sports app deal will be also hit with a £1 a month price rise.
And it said those who have BT Sports channels as an add-on with Sky will also be affected.
BT announced earlier this year that it will not be increasing prices for broadband customers in 2019.
From March 2020, broadband, landline and mobile plans will increase in line with the CPI rate of inflation from the January each year.
A BT spokesperson said: “We’re contacting some of our BT TV and BT Sport customers to let them know of some changes to their pricing from the 28th July. Some customers will see no changes at all and we believe we continue to provide unrivalled value for money when it comes to TV and sport content our customers love.
“Next season will be the biggest yet for BT Sport and customers will have access to live and exclusive UEFA Champions League and Europa League matches and highlights, 52 Premier League games - ten extra Premier League games, all European and Premiership Rugby Union matches, UFC, unmissable world title boxing, cricket, tennis, MotoGP and much more."
Dani Warner, utilities expert at uSwitch.com, said: "BT’s legion of customers will be hit hard by these rises, with just a few pounds a month very quickly adding up and potentially proving costly in the long run.
"BT Sport, driven by its football offering, is a premium product, but many will feel they were already paying a substantial amount to enjoy it.
"Price rise announcements are often good moments for customers to assess whether they are really getting value for money for their service, and BT has to be wary of any complacency when it comes to its users’ loyalty.
"There is more choice than ever in both services and providers. Just last week, we noted there could be as much as wanting to watch the upcoming season across various subscription services, including BT Sport.
"Ultimately, BT will have to show itself to be offering value, regardless of the prices it is demanding, or customers will vote with their feet - which they can do for free mid-contract as a result of this increase.
"That represents a clear risk for BT: will its users happily stump up the extra cash each month, or will they now explore the myriad other options that might offer them better value?"
What are my rights?
Anyone affected by the price hikes will be able to remove the BT TV and Sport part of their BT package penalty-free within 30 days of receiving the notice of the price change.
You won't, however, be able to cancel the phone and broadband part of your package if you're still within the minimum term of your contract.
