Staycation prices a third higher in holiday hotspots this year When can I go on holiday? What Med destinations will look like this summer The countries already rolling out vaccine passports Sign up to the Telegraph Travel newsletter Passengers travelling overseas from England will be required to complete and carry a 'Declaration to Travel' form, starting from Monday. Airlines, ferry companies and train operators will be legally obliged to explain on their websites that the document must be filled out before travelling. They will then check that passengers have completed the form before they board – individuals who have not done so may not be allowed to join the service they have booked. Anyone identified by police as trying to travel overseas for reasons that are not currently permitted will be asked to return home and they risk receiving a fixed penalty notice for breaking non-essential travel rules. These fines start at £200 and double for each incident; they can go up to a maximum of £6,400. This measure is a "necessary step to protect the public and our world-class vaccination programme", Home Secretary Priti Patel told parliament in January; the details, however, were not published until Friday, some 40 days after it was announced. The form is not required for travel within the UK, to Ireland, to the Channel Islands or the Isle of Man, the government's guidance states. Different border rules apply for travel abroad from the devolved administrations. Foreign holidays are currently prohibited under lockdown legislation, and will not be permitted from England until May 17 – at the earliest. All travellers returning to England are subject to a 10 day quarantine, with arrivals from red-listed countries required to pay up to £1,750 for a stay in a designated hotel.
