Passport Office issues advice as part of their Contingency Planning in the event of a No Deal Brexit

UK nationals travelling to the EU after 29 March 2019 need to have six months left on their UK passport from the date of travel. This applies to both adult and child passports. Those who have had extra months added to their existing ten year UK passport, because they renewed their old passport before it expired, may find that these additional months do not count towards the six months that should be remaining. As the UK could crash-out the EU at the last moment, it is therefore important that any customer with a passport that expires within six months of their date of travel get their passport renewed as soon as possible.
