With effect from 8 April 2015 Eurotunnel and all ferry operators will be required to scan the passports of those leaving the UK and send this information through to the Home Office. The government is currently trialling some exemptions such as coach tours and in situations where there are big delays, Companies may relax controls with advance approval from a minister.
These exit checks are being reinstated following their demise in 1994. To avoid delays airlines already obtain advance passenger information (API) and submit this information to the Home Office and so there will be no change at UK airports. Eurotunnel will also be introducing API in April to help reduce delays and it is to be hoped that the ferry companies will follow suit.
