From July, BT TV customers will have to pay more for the Kids, Kids Extra and Music channel packages.
The three bundles currently cost £3 a month each. But from July 3rd, this will increase to £4 a month.
The Kids bundle gives viewers the Diney Channel, Disney Junior, Disney XD, Nickelodeon, Nick Junior, Nick Toons, Boomerang, Cartoon Network and Cartoonito. Kids Extra is the same package for those taking the entertainment channels.
The BT Music bolt-on only adds one channel: BT Music. This includes interactive elements, so you can make your own playlist while watching other music videos.
From July, the standard price of line rental will also go up. BT customers will pay £18.99 a month, up from the current rate of £17.99 a month.
Those paying the year's line rental upfront will also be hit with a price rise. A year's worth of line rental will increase from £194.28 to £205.08.
The price rises were revealed on BT's Products and Services page.
The basic BT TV package is available for free to all BT Broadband customers. It offers channels not available on Freeview via an internet connection, and lets customers add extra channels like Sky Sports and Netflix.
Last week, BT announced it was also increasing the price of BT Sport from July 3rd. The standard definition channels will still be free for BT TV customers, but the HD versions will now cost £5 a month instead of £4. BT Sport on Sky TV is also going up, from £19.99 a month to £21.99.
BT isn't the only firm to raise its prices recently. From June 1st, Sky is also raising its prices, in some cases by as much as £2.50 a month.
