It is very difficult to give an accurate figure to the cost of cyber crime to the UK economy.
For example, the Detica "Cost of Cyber Crime" report, published in February 2011 in partnership with the Office of Cyber Security and Information Assurance in the Cabinet Office, estimated the cost of cyber crime to the UK to be £27 billion per annum. A copy of this report will be placed in the House Library.
A truly robust estimate will probably never be established, but it is clear the costs are high and rising.
This is why the Government have committed £650 million to the National Cyber Security Programme to support economic prosperity, protect national security and safeguard the public's way of life by building a more trusted and resilient digital environment.
