Insurance market Lloyd’s of London is to establish a subsidiary in Brussels to maintain a presence in Europe once Britain divorces from the EU.
The company said the Belgian capital emerged at the top of its list after scoring highly with executives for its regulatory framework and access to talent.
The move means Lloyd’s will be able to write risks from all 27 European Union and three European Economic Area states after Brexit.
Chief executive Inga Beale told the BBC’s Today programme: “What we were after was some jurisdiction that had a really robust reputation for regulation, we also wanted to be able to access talent and we wanted really good accessibility.
“Brussels came out top of our list.”
However, she said tax was not a factor in the company’s decision when choosing a new EU base.
Lloyd’s, which employs 700 people in London, aims to start work at the Brussels office from January 1 2019.
It is believed the move will result in around 100 jobs being shifted from London, though that number could rise as the insurance market establishes itself in Belgium.
It came as the company unveiled its full-year results, with profits flat for 2016 after the firm wrestled with “extremely challenging” conditions driven by pricing pressures.
Annual pre-tax profits came in at £2.1 billion, the same as the year before, but gross written premiums lifted 11% to £29.9 billion over the period.
It said the level of major claims had reached £2.1 billion – the fifth highest since the turn of the century and above the long-term average – following Hurricane Matthew and the Fort McMurray Wildfire in Canada.
In line with the insurance industry, the firm was also impacted by Government changes to the way personal injury claims are calculated with its cut to the Ogden discount rate.
However, it said it was making progress on global markets, emerging as the leading player for excess and surplus lines in the United States, shifting half its managing agents to Shanghai and Beijing, and winning approval for a reinsurance office in Mumbai, India.
