Your Personal Data may be processed outside of the UK. This is because the organisations we use to provide our service to you are based outside the UK.

We have taken appropriate steps to ensure that the Personal Data processed outside the UK has an essentially equivalent level of protection to that guaranteed in the UK. We do this by ensuring that:

• Your Personal Data is only processed in a country which the Secretary of State has confirmed has an adequate level of protection (an adequacy regulation), or
