Wannacry cost the NHS a total of £72m according to estimates from the Department of Health and Social Care.

The cost is estimated to be around £19 million in lost patient care output, based on the findings that 1 per cent of NHS services were disrupted over a one-week period.

In addition to the lost services, it’s believed a further £500,000 was spent on dealing with the immediate effects of the IT failure, including the hiring of additional consultants.

The biggest costs came in the June-July period immediately following WannaCry, which is estimated to have cost a further £72 million as the NHS worked to restore its services to full operation and to recover its data.
