Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many times the London Ambulance Service has experienced computer system failures in (a) one and (b) more than one of its control centres in the last (a) 30 days, (b) six months, and (c) twelve months; and how many of these failures were associated with high call volumes.

NHS England advises that the London Ambulance Service NHS Trust has experienced one computer system failure in the last 30 days; three computer system failures in the last six months; and four computer system failures in the last 12 months, inclusively.

Computer system failures have been defined as an IT failure which has been declared as a business continuity incident by the Trust at its two Emergency Operations Centres. None of the incidents were associated with high call volumes.
