The rules allow you to take food bought before security on board, as long as is not "liquid or semi-liquid" like yoghurt, jam, soup, honey or syrups. A sandwich, salad, cake or pasty should be fine. Essentially, if it's got a lot of liquid, don't bring it.

Yes, you can absolutely take your own food through airport security in the UK, provided the items are in a solid state. In 2026, the primary restriction remains the liquids rule; any food that is considered a liquid, gel, or paste (such as soup, honey, jams, or thick sauces) must be in a container of 100ml or less and fit within your clear plastic liquids bag. However, solid foods like sandwiches, fruit, nuts, chocolate, and even cooked meats or pies are perfectly acceptable in your carry-on luggage. It is important to note that many UK airports, such as London City and Teesside, have upgraded to next-generation CT scanners that allow you to leave liquids and large electronics in your bag, making the food inspection process much faster. However, if you are traveling internationally from the UK, you must be mindful of the customs regulations at your destination. For example, entering the EU or the US with fresh meat, dairy, or certain fruits can lead to heavy fines, even if the food was allowed through the UK security checkpoint.
