BT TV customers can now have YouView+ boxes in different rooms in their homes.
The service provider is giving subscribers the option of taking an additional box, allowing them to watch premium channels on more than one TV set.
Customers taking a 12-month Extra Box subscription have access to the same channel subscriptions and bolt-ons.
The advent of super-fast fibre broadband has made this possible, with TV viewers able to stream live content on multiple television sets in HD quality.
BT's Extra Box package costs £5 per month, and customers need to purchase an additional BT YouView+ box for £99.
The second box offers all the functionality of the first, including seven-day catch-up TV, and pause, record and rewind options.
BT is continuing to attract customers to its pay-TV service, with the number of subscribers passing the one million mark in March 2014.
In January, BT became the first pay-TV provider in the UK to offer movies to buy-to-keep as well as rent, while in February, the firm extended its line-up with the addition of Discovery, TLC, Animal Planet and British Eurosport 1 and 2 in HD.
Another development this year was the introduction of the "fastest, smallest" YouView box on the market - a device BT claims has received "rave reviews".
Alex Green, Director of TV for BT, said the firm is "delighted" to be able to offer BT customers the added flexibility of having two YouView+ boxes in their home.
"Over the past year, we have transformed our service by introducing pay TV channels delivered in fantastic HD quality on our market-leading YouView+ box," he stated.
"We believe this offers the best-quality TV experience and the most competitive bundle with fibre in the market."
Mr Green noted that BT's line-up is growing by the month and offers everything from premium sport to movies to download to own.
"Our recent developments have been extremely well-received by customers," he added.
"We now have a very strong foundation for growth as we carry on expanding our service."
