The network, which has branched out into several channels and the Web since its foundation as an independent Arabic news channel in 1996, will be able to reach 80 percent of Britain's 25 million households.
Al Jazeera English is already available on satellite platforms Freesat and Sky in Britain, and reaches about 200 million homes worldwide, mostly on pay-TV platforms.
Al Jazeera, which is based in Doha, aims to provide an alternative view of international news to those provided by other, Western global news providers like the BBC or Time Warner's CNN.
The sometimes dissenting views of the network, which was best known in the West for broadcasting hostage videos and messages from Al Qaeda leader Osama Bin Laden, have caused controversy in many Middle Eastern countries.
Al Jazeera English was launched in 2006.
