The Charity Commission will move to smaller offices in London this weekend.
The regulator will move from its current base on Millbank in central London to nearby offices at 1 Drummond Gate, Pimlico, on a five-year lease, breaking the nine-year lease it signed on its Millbank offices in 2009.
A commission spokeswoman said staff would begin to move from the Millbank offices this afternoon and will be working from the new Pimlico offices on Monday. She said services would not be affected by the move.
In a statement, the commission said the relocation was prompted partly by its desire to cut costs. The move will reduce the commission’s running costs from just under £1.1m to £504,000 a year.
The commission’s budget is falling from £29.3m in 2010/11 to £21.3m in 2014/15.
