SKY customers will lose access to a free streaming service included in their TV package next year.
The platform - which launched in 2021 - was also available on NOW.
Peacock was home to shows by US giant NBCUniversal.
These include Bel-Air, Young Rock, The Resort, Below Deck, Vampire Academy and The Real Housewives of New Jersey.
Despite being a huge streaming service across the pond, Peacock struggled to make a dent in the UK market - mostly due to a lack of programming on it.
Nevertheless, some fans have taken to social media to share their disappointment.

Reality TV programmes like The Real Housewives of Orange County can be found on Hayu, which is a paid extra.
Peacock UK's demise is the latest big shake-up in the streaming wars, after it was announced that Lionsgate+ will close down too next year.
The move to close Peacock in the UK comes as owners Comcast recently announced that the platform saw $2.8billion in losses this year, despite having 30million paid subscribers.
“We’re focused on domestic, we can take the content that doesn’t go into Peacock and monetize it outside of the United States,” Comcast CEO Mike Cavanagh explained.
"I think for us, that’s not the ambition, we’ll figure out how to make sure our international joint ventures and partnerships and the like solve the problem of what it means not to have a global service of our own, and that can change over time.
"But our primary focus is figure out domestic and make sure that we continue to have the reach and relevance between linear and digital as we look several years down the road."
