Following the UK's departure from the EU, the rules for bringing tobacco back from France have changed significantly. As of 2026, the "Duty-Free" allowance for passengers arriving in the UK from any country (including France) is strictly 200 cigarettes. Alternatively, you can bring 100 cigarillos, 50 cigars, 250g of tobacco, or 200 sticks of tobacco for heating. You can split this allowance—for example, bringing 100 cigarettes and 25 cigars—but you cannot exceed the total 100% limit. If you exceed this amount, you are legally required to declare the goods and pay the full UK VAT and excise duty on the entire quantity, not just the excess. It is a common misconception that you can bring "unlimited" amounts for personal use; that rule only applied when both countries were in the EU Single Market. Customs officers at Dover, St. Pancras, and UK airports are increasingly diligent in enforcing these 200-cigarette limits, and failing to declare overages can lead to the seizure of all your tobacco and potential fines.
