At London Stansted, liquids under 100ml can stay in your hand luggage, but the airport has no universal rule keeping laptops packed on every lane. On legacy 2D lanes you’ll still be told to remove them and place them flat.
At London Luton, all security lanes use CT scanners. Laptops and liquids under 100ml stay inside your bag. Throughout the UK, no official list says which airports let electronics stay in bags — you read the lane, not the airport name.
British airport security used to run on a simple script: laptops out, liquids in a plastic bag.
Fly out of Luton and you can walk through with a laptop buried under a hoodie. Return through a legacy lane at Stansted a week later and a security officer will ask you to take it out and lay it flat. Same country, same airline, different rule.
This article maps what the two low-cost hubs actually say about electronics screening, and why the machine behind the belt — not the airport name on your boarding pass — decides what you unzip.
Stansted: clear on liquids, silent on laptops
London Stansted Airport‘s security page, last updated April 2026, is explicit about liquids: containers over 100ml are barred, even if only part full. Under that size, bottles can stay in your hand luggage and no plastic bag is required. Ask the same page whether laptops stay in bags on every lane and it goes quiet.
An older Easter advisory from 2023 told passengers to remove all electronic items, including laptops and iPads, and lay them flat in trays. The current page doesn’t repeat that instruction. But it also doesn’t replace it with a keep-everything-packed promise. Stansted has confirmed it doesn’t yet have CT scanners on every lane, which means some checkpoints still run on 2D X-ray. On those lanes, the old routine holds.
If you draw a legacy lane, expect the laptop out. If you draw a CT lane, you may keep it in. The trouble is you often can’t tell which is which until the signage changes or the officer tells you.
Luton: every lane changed, but the 100ml cap stayed
London Luton Airport spent £20 million on next-generation cabin baggage scanners and says every security lane is now CT-equipped. Its rollout announcement is blunt: passengers no longer need to remove liquids or electronic items as they pass through security. That covers laptops, tablets, power banks tucked into pouches.
The fine print on liquids hasn’t changed. Containers must still be 100ml or less under current government rules. What changed is where they screen: inside the bag, not in a plastic tray with a separate plastic bag. Luton calls it an “in the bag” revolution, and for early morning passengers it has added a free pre-booked security slot between 03:00 and 04:30 to move through faster.

The table: how eight UK airports split on the same question
Place Stansted and Luton next to Heathrow and Gatwick, and the inconsistency gets sharper. Heathrow and Gatwick allow liquids up to two litres and laptops stay inside bags across all terminals. Luton is fully CT but capped at 100ml. Stansted is mixed-lane. The table below shows what is verifiable for eight airports, with the gaps marked honestly.
| Airport | CT deployment status | Electronics removal rule | Liquid rule | Source and last update |
|---|---|---|---|---|
| London Stansted (STN) | CT on some lanes only; not all fitted | Legacy lanes require laptops out flat; CT lanes may allow in bag; no universal rule | Over 100ml banned; under 100ml can stay; no plastic bag | Stansted security page April 2026; Easter travel advice 2023 |
| London Luton (LTN) | All lanes CT-equipped after £20m upgrade | No need to remove laptops or large electronics | Containers 100ml or less; keep in bag; no plastic bag | Luton press release and security tips 2024–2026 |
| London Heathrow (LHR) | CT across all checkpoints in all terminals | Laptops and tablets stay in cabin baggage | Up to two litres, stay in bag, no plastic bag | Heathrow announcements and security pages January–August 2026 |
| London Gatwick (LGW) | CT phased across checkpoints; transformed security | Laptops/electrical items stay in hand luggage | Up to two litres; stay in bag; metal bottles may need separate screening | Gatwick security page and media centre 2025–2026 |
| Manchester (MAN) | CT on upgraded lanes | CT lanes keep electronics in bag; 2D lanes require removal; no unified rule | 100ml limit even with CT | Consumer guidance; airport statements limited |
| Birmingham (BHX) | CT installed at checkpoints | CT lanes keep laptops in bag; older lanes may require removal; no lane docs | Containers stay in bag but capped at 100ml | Consumer reporting; no official summary |
| Edinburgh (EDI) | CT introduced but no full CT-only claim | CT lanes allow in bag; older lanes may differ; no definitive statement | 100ml per container despite CT | Consumer guides/news; airport pages lack policy summary |
| Bristol (BRS) | CT on some lanes listed in media | CT lanes keep laptops in bag; older lanes may require removal; no unified statement | Liquids stay in bag; 100ml limit enforced | Media coverage/consumer guides; partial documentation |

For Manchester, Birmingham, Edinburgh and Bristol, the “not fully documented” note is not a failure of research. Those airports simply don’t publish a single consolidated page equivalent to Heathrow’s. Consumer guides and news coverage carry most of the CT allowance information, which is why two equally current web pages can contradict each other.
How to spot which scanner is actually in front of you
CT lanes tend to announce themselves. Look for larger scanner units that produce 3D images, automated tray return, and messages telling passengers to keep items in bags. A traditional 2D lane usually has shallower trays, manual stacking, and signs requesting laptops out and liquids presented separately.
Even on a CT lane, an officer can still ask you to remove electronics if the bag looks too cluttered or the image comes back ambiguous. Dense packing with vertical separation helps the scanner identify individual objects. And if you’re used to TSA PreCheck, remember that programme keeps electronics in bags no matter what scanner is operating. The UK has no equivalent lane-level consistency.
Why no UK list tells you which airports let laptops stay in bags
The only primary UK document naming approved scanner models is the Department for Transport’s security scanners list on GOV.UK. It names hardware. It does not say which airport uses which model, and it says nothing about whether passengers must remove laptops at any given checkpoint. That omission is not an oversight; the list exists for procurement and approval, not passenger guidance.
Once CT is fully live, keep-laptops-in-bag statements come from individual airports. Heathrow and Luton publish their own. For Manchester, Birmingham, Edinburgh and Bristol, official pages either omit lane-level detail or default to generic UK liquid limits, leaving consumer guides and news coverage to carry the CT allowances. That’s why two equally current web pages can contradict each other.
There is no authoritative, publicly searchable UK-wide database of electronics-in-bag rules. The DfT list won’t answer that question; it was never designed to.
What this means for you
Pack as if you might get the older lane. Keep your laptop and tablet in an easy-to-reach pocket, not buried under shoes and cables. If a CT scanner reads a cluttered bag and can’t separate objects, an officer can still ask you to remove items even in a CT-only airport. Dense packing with vertical separation helps the scanner do its job.
At the lane, look before you unzip. Larger scanner units with automated tray return and signs saying “leave everything in your bag” mean CT. Shallow trays, manual stacking and signs asking for laptops out mean 2D. The sign wins, always. Posted signs and local officers override general advice because lane configurations vary within the same terminal.
If you’re flying from Luton, you can keep electronics in. From Stansted, be prepared for either. And remember the return leg can reverse your experience if you connect through Heathrow, which is fully CT but has different liquid rules.
Questions? Answers.
What items are not allowed on a plane in hand luggage in Stansted?
Stansted bars liquids in containers over 100ml, even if the container is only partially full. Liquids under 100ml can remain in hand luggage. The security page specifically highlights the 100ml liquid restriction.
Why do Stansted and Luton apply different electronics rules if both are UK airports?
Luton has all security lanes equipped with CT scanners, so passengers no longer need to remove laptops and other large electronics. Stansted does not have CT scanners on all lanes, so legacy lanes still require electronics to be removed and placed flat in trays. UK rules do not mandate uniformity, so scanner deployment drives the variation.
Can I keep liquids in my bag at Luton even though the 100ml limit still applies?
Yes. Luton’s CT scanners allow passengers to keep liquids inside cabin bags, but each container must be 100ml or less under current government restrictions. No plastic bag is required.
Is there an official UK-wide list showing which airports let electronics stay in bags?
No. The Department for Transport publishes a list of approved security scanner models, but it does not break down airport-by-airport electronics rules. There is no authoritative database of which airports allow laptops to stay in bags.
What do the rules at Heathrow and Gatwick mean for my return journey?
Both Heathrow and Gatwick allow liquids up to two litres and laptops to stay inside bags after their CT rollouts. If you depart from Stansted or Luton and return through Heathrow or Gatwick, expect different liquid limits and possibly different electronics rules, depending on the lane.
