Swindon Borough Council alleged Clearsprings “failed to comply with regulations in respect of management of housing in multiple occupation” 27 times between May and October 2022.
Before the firm paid the fines, the council said it was prepared to take the matter to court.
Specific allegations included failing to ensure fire doors closed properly, failing to ensure a bedroom could be opened from inside the room and failure to ensure that smoke alarms and other safety measures were working at five different properties across Swindon.
There were four charges that an employee of the company “knowingly or recklessly supplied false or misleading information to a housing authority” when they did not disclose to the council that they had been convicted of a previous housing offence.
In October last year, the BBC reported it had been contacted by people living in Clearsprings accommodation who said they were being provided with inedible food and that toilet paper and sanitary products were being rationed.
The projected Home Office payment to Clearspings over a 10-year contract is £7bn.
