Slater and Gordon is set to close its London office as its people prepare to work from home permanently starting in September.

In a first in the U.K., the Australia-based law firm will close its London office and will conduct a review of all its other U.K. offices in September. It comes as the firm's workers start their third month of working remotely under the COVID-19 lockdown.

Once the firm's lease for the London office ends in September, all 200 London employees will work from home most of the time, although the firm is hoping to find a smaller office space to host meetings.

The firm is yet to make any concrete decisions regarding its lease commitments to its offices outside of London.

The firm's chief executive David Whitmore said in a statement: "Today we have announced to our staff that we won't ever go back to how we worked before COVID."

He added, "When we do look to return to our offices they won't look like they used to and colleagues will be encouraged to continue working remotely for the majority of the time. Working smart is better for everyone."

Whitmore said that the firm's offices are likely to run to just 35% capacity while social distancing restrictions remain. Staff will be provided with multiple screens if they are needed and homes fitted with comfortable office equipment.

The decision comes as other firms, such as Baker McKenzie and DLA Piper, have been canvassing staff on the prospects of returning to their offices after the lockdown.
