Executive Summary
UK airport security follows national rules on liquids, sharp objects, batteries and dangerous goods, yet liquid limits and screening equipment still vary between airports. Some items are fine in hand luggage, others must travel in the hold, and a few are banned entirely. Checking these rules before packing helps passengers clear security quickly and keep their belongings.
Have you ever watched a passenger surrender a favourite perfume at the security desk? It is a disheartening moment, and it usually happens because someone missed a rule. The good news is that the guidance is simple once you see it laid out. Let us go through it together so packing feels easier.
What Are the UK Airport Security Rules for Passengers?
Security regulations apply to every passenger leaving a UK airport. The Civil Aviation Authority explains that individual airports can confiscate anything they consider dangerous, even if it does not appear on the official prohibited list, and GOV.UK confirms that security staff will not let through anything they consider dangerous.
Airports differ in the screening equipment they use and the amount of liquid they allow. It is safest to read the rules for your departure airport, and any airport you will pass through, a few days before you travel.
What Can You Take at Airport Security in the UK?
Quite a lot, as it happens. Government guidance and airport advice agree on the following everyday items.
Everyday Personal Items
Umbrellas, walking sticks, nail clippers, tweezers and knitting needles are all acceptable in hand luggage. Small scissors with blades no longer than 6cm and disposable razors with a fixed cartridge are allowed too, according to GOV.UK.
Electronics and Batteries
You can bring phones, tablets and laptops in your cabin bag, although some airports may ask you to take out larger devices so they can be scanned separately. Power banks must be carried in your hand luggage, with a maximum of two per person, and power banks over 100Wh and up to 160Wh require airline approval.
Medicines and Baby Essentials
Essential medicines are welcome in hand luggage. If you are carrying liquid medicine in containers over 100ml, you will need supporting documentation, such as a prescription or a letter from your doctor. You can bring baby food and milk in containers of up to 2 litres through all UK airports.
Food and Snacks
Solid foods such as sandwiches and fruit are acceptable. Food and powders can obscure X-ray images and trigger a manual bag check, so packing them in the hold saves time. Frozen items are usually not allowed in hand luggage, although exceptions apply for some medicines, medical needs and baby food or milk.
Lighters and Vaping Devices
You may carry one lighter, sealed in a resealable plastic bag and kept on your person throughout the flight. E-cigarettes must travel in hand luggage only and must never be recharged on board.
Mobility Aids and Musical Instruments
Pushchairs, walking aids, and wheelchairs are usually allowed in the cabin after security screening. Check with your airline in advance if you are travelling with a battery-powered mobility aid. Large musical instruments are screened separately, so contact your airline before booking if you need an extra seat.
What Liquids Can You Take at Airport Security in the UK: The Key Limits
Liquids cover more than drinks. Soup, jam, honey, creams, sprays, toothpaste, gels, and contact lens solution all count. At most airports, each container must hold no more than 100ml, even if it is only part full. Check the rules for your departure and return airports, as some now allow containers of up to 2 litres.
Where a transparent bag is required, use one resealable bag per person that holds no more than a litre and measures about 20cm by 20cm. Show it at the security point and do not tie it at the top. Essential medicines, special dietary liquids and baby items are exempt at all UK airports, and sealed duty-free purchases can go through with the receipt visible.
What Items Are Not Allowed at UK Airport Security?
Some items never board a plane. Fireworks and pyrotechnics, flares and party poppers are prohibited in both hand and hold luggage, as are bleach, corrosive substances, and poisons. Other items, such as golf clubs and cricket bats, are permitted in the hold only, and your airline may want advance notice.
| Item | Hand luggage | Hold luggage |
| Knife with a sharp blade or a blade over 6cm | No | Yes (check with airline) |
| Large scissors (blades over 6cm) | No | Yes (check with airline) |
| Corkscrew | No | Yes |
| Golf clubs and cricket bats | No | Yes |
| Fireworks and flares | No | No |
| Party poppers | No | No |
| Bleach | No | No |
UK Airport Baggage Security Rules for Cabin and Hold Bags
Your airline decides how many bags you can carry into the cabin and how large they may be. As a guide, Gatwick advises one piece of hand luggage measuring up to 56cm by 45cm by 25cm, and many airlines also allow a small handbag. Hold bags follow your airline’s weight limit and are the right place for sharp items, sports equipment and larger liquids.
