According to the 2021 Islam in London census, there were 1.3 million Muslims in the Greater London area. This represents about 15% of the population of London.

Muslims contribute greatly to London’s economy. A 2013 report documented 13,400 Muslim-owned business in London, representing more than 70,000 jobs and over a third of small and medium enterprises (SMEs) in London.

The first mosque in London was built in 1895. There are now over 1,000 mosques in London. They are projected to outnumber churches there by 2030.

Hate crimes targeting mosques have increased. The Independent reported that across the UK such incidents more than doubled between 2016 and 2017.

Following the 15 March 2019 Christchurch massacres, a 593% increase in hate crimes against Muslims in the UK was recorded.
