London has beaten New York in luring the largest amount of fundraising deals for financial technology companies so far in 2019, fresh research shows.

The U.K. capital's fintech sector attracted a total of 114 deals worth a record $2.1 billion in the first eight months of the year, according to figures shared with CNBC by industry group Innovate Finance and Mayor of London Sadiq Khan's promotional agency London & Partners.

While San Francisco still tops London in terms of total deal value —start-ups in the Californian city raised $3 billion — outfits in the U.K. capital won the most amount of funding rounds, the study said. New York firms snagged 101 fintech deals while San Francisco saw 80.

London also came out $200 million ahead of New York on total deal value, with fintech firms in the U.S. city having raised $1.9 billion. That was followed by Belgium at $881 million and Stockholm at $735 million.

The research was compiled using data from private capital markets research firm Pitchbook.

Charlotte Crosswell, CEO of Innovate Finance, said the development revealed a step change within London's fintech industry, with the likes of Monzo and OakNorth attracting huge nine-figure mega rounds.
