A care home in Tunbridge Wells has been closed down over concerns about the safety of its residents and the standard of care provided.
Four Nevill Park, run by Evesleigh Ltd, looked after up to 24 adults with autism and challenging behaviour.
The watchdog, the Care Quality Commission (CQC), has withdrawn its licence following an unannounced visit by inspectors.
Evesleigh said it was a "sad and distressing time for all concerned".
Inspectors found staff at the care home lacked skills and experience and residents' complaints were not recorded.
They said residents did not have adequate support plans, there were low staffing levels and poor documentation.'Protect residents'
Roxy Boyce, the regional director for CQC in the South East, said: "We have acted quickly to protect the safety and welfare of people at Four Nevill Park.
"The only way to properly protect residents was to close the home immediately."
Kent County Council has found alternative accommodation for residents.
In a statement, a spokesman for Evesleigh said: "The CQC believed that there was the potential for incidents to take place in the home.
"In their view the service lacked sufficient safeguards to ensure that people were safe from the risk of abuse or the risk of harm."
He said the company worked with residents and their families to find new accommodation.
"This was both a sad and distressing time for all concerned," he added.
