The new roles, mostly based at its London offices, will increase the firm's headcount by 50% and will cover engineering, developer and sales roles.
Nicola Mendelsohn, Facebook’s head of Europe, released a statement saying: "The UK remains one of the best places to be a tech company and is an important part of Facebook's story. We came to London in 2007 with just a handful of people, by the end of next year we will have opened a new HQ and plan to employ 1500 people.
"Many of those new roles will be high skilled engineering jobs as the UK is home to our largest engineering base outside of the US and is where we have developed new products like Workplace.
"The UK is also home to our Aquila facility in Somerset that is designing and building solar power unmanned planes that will connect remote area of the world to the internet."
Mayor of London, Sadiq Khan, added: "Facebook's decision to expand in London is further evidence that London’s strength as a tech hub keeps on growing.
"It follows news this week that London remains the best city in Europe for digital startups. The capital's vibrant tech scene is the envy of Europe and Facebook's continuing commitment is another sign that London is open to talent, innovation and entrepreneurship from all four corners of the world."
