The new changes mean that a bottle of wine in Heathrow could be up to £2.23 cheaper when travelling to Spain after Brexit.

Treasury Minister Kemi Badenoch said: “The government is taking advantage of the opportunity provided by the UK’s new relationship with the EU to enable passengers travelling from GB to the EU to purchase duty-free excise goods once they have passed security controls at airports, ports, and train stations on international routes, on the same basis as currently applies to passengers travelling to non-EU destinations.
“This means passengers travelling from GB won’t have to pay UK VAT and excise duty on these purchases of alcohol and tobacco products when they travel to an EU destination.
“They will also be able to purchase duty-free goods on-board planes on international routes, on international train journeys and ships sailing from GB to a destination outside the UK for consumption on-board and to take-away.
“This is something that many businesses have raised as part of the consultation and the government will implement this as soon as the transition period ends.”
