The FCA has agreed a deal to quit its Canary Wharf offices and move to the Olympic Park site in Stratford.
The regulator has secured a 20-year lease on a 430,000 sq ft site in the Stratford International Quarter development next to the Olympic Park.
The move is set to go ahead in 2018 when the FCA’s current lease ends.
The FCA board considered a number of options but chose the Stratford site based on factors including value for money and location, Money Marketing understands.
An FCA spokeswoman confirmed the move but declined to comment further.
In the FCA’s business plan for 2014/15, published this week, it listed accommodation and office services costs at £30.6m for the year.
This accounts for 7 per cent of its budget and compares to a cost of £32.9m for 2013/14.
The costs relate to the FCA’s offices in Canary Wharf and Edinburgh.
Last month it was reported the regulator was considering a move to the Stratford site as well as an alternative Canary Wharf office block.
