The single most useful thing a pregnant visitor can do in London is get a Baby on board badge, and the important detail is that you can collect one in person: TfL Visitor Centres and the London Transport Museum in Covent Garden hand them out, so you do not need a UK address. It is free, it works on every part of the network, and it makes a considerable difference on a full Tube train.
This page describes what the official sources say and stops there. We are a travel guide, not a medical one, so anything about your own pregnancy belongs with your midwife or doctor and with the NHS pages we link to. What we can do is tell you where the lifts are, which lines are hot, where the toilets are, and how the NHS treats a visitor who needs help.
The badge, and why it is not the same as the other badge
TfL runs two seat badges and they work differently for someone visiting from abroad.
The Baby on board badge is free and can be ordered online for delivery, requested by phone on 0343 222 1234, or picked up in person from a TfL Visitor Centre or from the London Transport Museum in Covent Garden, at either the ticket desk or the museum shop. There is a separate "Babies on board" badge for twins or more, available from Customer Services by phone or from the Visitor Centres. One badge per person.
The "Please offer me a seat" badge, for people whose need for a seat is not visible, is also free but is posted to UK addresses only. For a visitor arriving without a UK address, the Baby on board badge collected in person is the one that actually works.
Neither badge guarantees a seat. TfL is explicit about that. What the badge does is remove the need to explain yourself, which on a crowded Central line train at 6pm is most of the problem. If nobody offers, ask a member of staff or another passenger directly.
On buses, the space by the doors is the wheelchair space, and wheelchair users have legal priority over it. It is otherwise first come, first served. Our page on British etiquette for visitors covers how seat-offering actually plays out in practice, which is politely and without discussion.
Lifts, steps and the parts of the network that work
London's transport is step-free in patches rather than as a system. The reliable parts are worth memorising.
- All 41 Elizabeth line stations are step-free from street to platform, and everything from Paddington to Woolwich, plus Heathrow, is step-free to the train as well.
- Every DLR station is step-free from street to train.
- 95 Tube stations are step-free, which is more than a third of the network but leaves the majority with stairs or escalators only.
- Every London bus is low-floor and the driver can kneel it to the kerb.
Two traps. Lifts and step-free are not the same thing: a station can have lifts and still not be step-free, because the gap or step between platform and train counts. And a long interchange inside a step-free station can still be a quarter of a mile of tunnel. Our guide to step-free and accessible transport explains how to read the symbols on the Tube map, and TfL's Journey Planner will build a step-free route if you select the accessibility option.
TfL also runs a free travel mentoring service which will plan an accessible route by phone or email, on 020 3054 4361 between 9am and 4pm on weekdays. It is aimed at disabled travellers but covers any journey on the network, and a visitor can use it.
A Tube in August, in actual degrees
The heat on the Underground is not evenly distributed, and the difference is large enough to change which route you take. Air conditioning exists only on the four sub-surface lines: the Circle, District, Hammersmith & City and Metropolitan lines share 192 air-conditioned trains, about 40 per cent of the fleet. The deep-level tube lines have none in service as of September 2026.
TfL's own platform temperature figures, measured in the evening peak in August 2024, rank the deep lines like this: Victoria 31.1°C, Central 30.6°C, Bakerloo 29.9°C, Northern 28.8°C and Piccadilly 27.4°C. The Piccadilly line's first air-conditioned trains are expected to enter passenger service some time between December 2026 and June 2027, so that last figure should improve.
In practice: on a hot day, take a District or Circle line train even if it is slower, or take a bus, or walk. Our page on which Tube lines have air conditioning has the full breakdown, and London in a heatwave covers the days when the answer is to stay out of the tunnels altogether.
There is no drinking water on the Tube and no toilets on the trains. Carry a bottle and fill it before you go down. Alcohol is banned on TfL services, but water is not, and staff will let you drink on a platform if you need to.
Finding a toilet, which is the real planning problem
TfL publishes a toilet map showing which stations have toilets and which have baby changing, and states that its own toilets are free, although facilities it does not manage may charge. Some station toilets are inside the ticket gates, which matters if you have not touched in.
Museums are the most reliable central option, because they are free to enter and their toilets are plentiful: the V&A alone has thirteen accessible toilets. The quiet rooms in the big museums also work as somewhere to sit down without buying anything, which is harder to find in central London than it should be. Our guide to public toilets in London lists the dependable ones by area, including the Great British Toilet Map, which is a privately run database rather than a government service.
What the NHS says about travelling, and about food
Two NHS pages are worth reading before you book, and we are not going to paraphrase them into advice.
On travelling, the NHS notes that many women find mid-pregnancy, between four and six months, the most comfortable time to travel; that the chance of going into labour is naturally higher after 37 weeks, or around 32 weeks with twins, and that some airlines will not carry you towards the end of pregnancy; that after week 28 an airline may ask for a letter from your doctor or midwife confirming your due date; and that long-distance travel of more than four hours carries a small risk of blood clots. It also suggests taking your maternity notes with you. Check your own airline's policy, because they differ.
On food, the NHS page on foods to avoid in pregnancy lists raw fish and raw shellfish among the things to avoid, and cooked shellfish among the things that are safe. That is directly relevant in London, because the oyster is one of the city's signature dishes and is served raw. Our guide to seafood and oysters in London tells you where to eat them; the NHS page is the authority on whether you should.
If you need help while you are here
Accident and emergency treatment is free to everyone in England, and so are GP and nurse consultations in primary care. Beyond that, overseas visitors who are not exempt are charged 150 per cent of the national NHS rate for hospital care, normally payable in advance.
Visitors from the EU, Norway, Iceland, Liechtenstein or Switzerland should check their own position before travelling: a valid EHIC or a Provisional Replacement Certificate covers medically necessary treatment during a temporary stay, including routine maternity care, but it does not cover a visit made in order to give birth or to get treatment. Norwegian residents are covered on a valid Norwegian passport. The NHS advises all visitors staying under six months to hold medical and travel insurance, and travel insurance and healthcare cover explains what to look for in a policy.
For something that is not an emergency, call 111 free at any hour, or use 111.nhs.uk, which can book you into an urgent treatment centre. Urgent treatment centres do not require you to be registered with a GP or to have a fixed address. Pharmacies can supply some prescription medicines without a GP appointment under the Pharmacy First scheme. Our pages on healthcare for visitors and pharmacies and minor illness go through the detail, and emergency numbers covers 999, 112 and 111.
Attractions that will and will not work
Most London attractions are simply a question of how much standing they involve. Two are worth naming because they publish an explicit position.
The London Dungeon says pregnant visitors are welcome but that it is mostly a standing and walking experience with little chance to sit down, and that the Drop Dead drop ride is not suitable during pregnancy. Staff will show an alternative route past it.
At the other end, the things that work best are the ones where you are sitting: a river boat, the top deck of a bus, the cable car, a theatre. The Tower of London needs two to three hours of walking on cobbles and stairs; the free national museums need as much or as little as you choose, and all of them have benches.
Where to stay, and the lift question
London's hotel stock includes a great many converted Georgian and Victorian terraces, and a large number of those have either a very small lift or no lift at all. If stairs are a problem, ask specifically whether there is a lift and which floor the room is on, rather than trusting a booking site's accessibility filter.
Choose the area by the station rather than the neighbourhood: being three minutes from a step-free station is worth more than any amount of charm. What a London hotel room is actually like is honest about the size and the stairs, and London with a baby is the page to read if you are coming back with one.
Frequently asked questions
How do I get a Baby on board badge as a visitor to London?
Collect one in person, free, from a TfL Visitor Centre or from the London Transport Museum in Covent Garden, at the ticket desk or in the shop. You can also order one online or by phone on 0343 222 1234. A separate badge exists for twins or more, available by phone or at the Visitor Centres.
Are priority seats on the Tube actually given up?
Usually, and a badge makes it much more likely because nobody has to guess. TfL is clear that neither of its badges guarantees a seat. If nobody moves, ask directly or speak to a member of staff, which is normal and not considered rude.
Which London Underground lines have air conditioning?
The Circle, District, Hammersmith & City and Metropolitan lines, which share 192 air-conditioned trains between them, roughly 40 per cent of the fleet. The deep-level lines have none in service as of September 2026; the Piccadilly line's first air-conditioned trains are expected between December 2026 and June 2027.
Can I use the NHS in London if I am pregnant and visiting?
A&E and GP consultations are free to everyone. Other hospital care is charged to non-exempt overseas visitors at 150 per cent of the NHS rate, usually payable in advance. A valid EHIC covers medically necessary care including routine maternity care for visitors from the EU and several other countries, but not a trip made in order to give birth. The NHS advises holding insurance.
Can I eat oysters in London while pregnant?
The NHS page on foods to avoid in pregnancy lists raw fish and raw shellfish among foods to avoid, and lists cooked shellfish as safe. London oysters are served raw. That is what the official guidance says; anything further is a question for your midwife or doctor.
