The Homes and Communities Agency (HCA) has found that Yorkshire Housing (YH) overlooked a significant number of overdue gas safety inspections.
The HCA notice said: “The breach exposed a substantial number of tenants to the potential of serious harm for lengthy periods.”
YH contacted the regulator to inform it that, during a management audit, a significant number of out-of-date gas safety certificates were identified.
In some cases the certificates had been expired for a long time.
The audit was conducted to check the effectiveness of controls that had been put in place following an internal audit in July 2013, which had raised concerns about data integrity when new homes were let.
The overdue servicing has now been completed and YH has put in place revised procedures.
YH is also commissioning an independent investigation to a brief agreed with HCA.
It will identify how the control failure happened and make recommendations for further actions to prevent a recurrence of the situation.
