As correctly indicated by the previous 3 replies above, you will need to apply for an export licence from the Export Control Organisation, part of the Department for Business, Innovation and Skills.
Please note that as of 17 October 2012, as a result of government-wide website changes, all our guidance about how to make a licence application is published on the GOV.UK website - https://www.gov.uk and not on Businesslink. Please remember to update any weblinks you may have.
There are various types of export licence which you might be able to apply for. The first type, as Sandra has indicated is an Open General Export Licence. To legally use a relevant OGEL you need to:
1. Know the 'rating' of your goods as listed on the UK Strategic Export Control Lists.
2. Check that the destination is permitted by the OGEL you intend to use
3. Ensure that you can meet all terms and conditions including record keeping requirements
To check terms and conditions you can use OGEL Checker - http://www.ecochecker.bis.gov.uk
If you either can't meet all terms and conditions or the goods or destination are not permitted by an OGEL then you need to apply for a Standard Individual Export Licence (SIEL).
To either register for an OGEL or apply for a SIEL you need to log in to the SPIRE export licensing database - https://www.spire.bis.gov.uk
