When travelling through London’s major airports — Heathrow, Gatwick, Stansted, and Luton — knowing the luggage rules can make or break your journey. From liquid restrictions in hand luggage to how many suitcases your airport transfer will take without extra fees, it pays to plan ahead.

This guide explains UK airport security baggage rules, what to expect at check-in and security, and what transfer companies (including WKG private transfers) allow when it comes to luggage.

UK Airport Security Rules in 2025

Carry-On Liquid Limits

• Most UK airports still enforce the 100ml liquid rule. Liquids, gels, and creams must fit inside one transparent, resealable 1-litre bag.
• Some airports (e.g. Birmingham, Edinburgh) have started easing rules, allowing up to 2-litre containers, but London airports have not universally adopted this yet.
• Always check the airport’s official website before flying.

Hand Baggage Size and Quantity

• Standard cabin bag size: 56cm x 45cm x 25cm.
• Most airlines allow two items: a cabin bag plus a personal item (handbag, laptop, or small rucksack).
• Exceeding limits usually means paying to check your bag.

Electronics and Devices

• Laptops, tablets, and large electronics usually need to be removed for security screening.
• Heathrow and Gatwick are gradually introducing scanners that let electronics stay inside bags, but this isn’t universal.
• Extra caution: Some inbound flights to Stansted (from Turkey, Egypt, Saudi Arabia) may have specific electronics restrictions.

Baby & Medical Supplies

• Exceptions apply for:
• Baby food, formula, and breast milk (up to 2 litres per container).
• Sterilised water for infants.
• Essential medicines, subject to screening.
• These must be declared separately at security.

Luggage Rules for London Airport Transfers

When booking a transfer from Heathrow, Gatwick, Stansted, or Luton, your luggage allowance depends on the vehicle type and provider.

Typical Allowance (Per Passenger)

• 2 medium suitcases OR 1 large suitcase + 2 cabin bags included.
• Applies to most private cars, shuttles, and taxis.

Additional Luggage Fees

• Exceeding this limit may result in extra fees or needing a larger vehicle.
• Always declare luggage quantity when booking. This helps ensure the right vehicle size.

Oversized Items (Sports, Instruments, Equipment)

• Items like golf clubs, skis, strollers, or musical instruments may require advance notice.
• Some providers charge a supplement or only accept these in minibuses/vans.

Why Luggage Rules Matter for Transfers

• Avoid surprise fees: If you show up with four large bags but booked a saloon car, you’ll likely pay extra or be rebooked in a larger vehicle.
• Travel time impacts: Extra luggage handling at pick-up adds waiting charges with some providers (but not with WKG).
• Vehicle safety: Cars are restricted by size/weight. Overloading is unsafe and non-compliant with UK transport law.

Tips for Smooth Travel with Luggage

• Check airline baggage rules: Cabin and hold allowances vary by airline.
• Pre-pack liquids correctly: Avoid delays at security checkpoints.
• Declare all bags when booking transfers: Ensure the right vehicle.
• Use luggage tags: Heathrow and Gatwick handle millions of bags; labels reduce loss risk.
• Travel light if using public transport: Trains and Tubes aren’t designed for oversized luggage.
