The Government do not hold information on how much has been received by UK companies for arms sales.
The Government do however publish information on the export licence applications it processes each year by destination. This includes the monetary value of items for which licences have been granted, and a summary of the items covered by these licences.
This information is available in the Government’s annual and quarterly reports on strategic export controls. The annual reports for the last five years are available from the Libraries of the House and the Foreign and Commonwealth Office (FCO) website at:

The quarterly reports are available on the BERR website at:
