Six hundred staff will work at the new location, following the closure of Redditch and Leamington offices.
They will be based at the Cube building, in the centre of Birmingham.
Chief Executive, Antony Townsend, said: "We are very enthusiastic about working together in a modern location at the heart of the City, improving our efficiency and effectiveness.
“Our new headquarters is readily accessible through excellent transport links, and allows us to benefit from Birmingham’s diverse recruitment pool.
"The move is part of a transformation of our organisation, and will help us to respond as a modern regulator to the dramatic changes taking place in the legal services market.”
The new address is 199 Wharfside Street, Birmingham B1 1RN
