Officers at Forest Gate Police Station have been "severely affected" by the devastating blaze which destroyed the roof of the building.
A senior police officer said it was a "difficult night" for Metropolitan Police officers based at the Romford Road station.
Romford Road remains unlikely to open until later today, the force added.
The entire roof of the police station was ablaze and almost 200 firefighters sent to tackle it after being called just after 4.15pm yesterday (March 6).
Commander Kyle Gordon, overseeing the recovery operation, said: “This was a difficult night for Met officers and staff, many of whom have lost their workplace and face uncertainty about their possessions but thankfully no-one based at Forest Gate Police Station was hurt.
"We know Newham residents may be concerned but I want to reassure them our local teams continue to provide a full service to keep them safe," he added.
