London Tube 2026: Oyster Card vs Contactless — Which to Use
How to ride the London Underground, buses and Overground: Oyster card vs contactless bank card, zones, daily caps and practical tips for visitors.
Transport · Updated 2026-08-26
London's transport network — Tube, buses, Overground, DLR and the Elizabeth line — is run by Transport for London (TfL) and uses a single pay-as-you-go system based on zones. Almost every visitor now chooses between an Oyster card and simply tapping a contactless bank card or phone, since both work the same way at the gates and apply the same daily fare caps.
How pay-as-you-go works
You tap in at the start of a journey and tap out at the end on Tube, DLR and Overground; on buses and trams you only tap once when boarding, since bus fares are flat regardless of distance. The system calculates your fare based on the zones you travel through and automatically applies the cheapest combination of fares for the day, up to a daily cap.
Oyster card or contactless?
A contactless bank card or a phone/watch with contactless payment enabled works exactly like an Oyster card at the gates, with the same fares and caps, and avoids the upfront cost and top-up hassle of a physical card. An Oyster card still makes sense if you don't want to use your own bank card abroad, if you're travelling in a group and want to load funds onto one card, or if your bank charges foreign transaction fees on small taps.
Daily and weekly caps
TfL automatically caps how much you pay in a day once you reach the price of a Day Travelcard for the zones you've used, so you never need to plan your exact number of journeys in advance. There is also a weekly cap (Monday to Sunday) that applies across multiple days, which matters if you're using contactless since the cap is calculated per card or device rather than per Oyster card unless it's registered.
Getting an Oyster card
Oyster cards are sold at Tube station ticket machines and many newsagents for a small refundable deposit, and can be topped up with cash or card at machines throughout the network. If you choose Oyster, register it online so you can track balance and journey history and protect any remaining credit if the card is lost.
Practical tips for visitors
Always tap in and out consistently — forgetting to tap out on the Tube or Overground triggers a maximum fare charge until you tap correctly on a later journey. Keep only one contactless card or device readily accessible when tapping, since holding two cards together at a gate can cause a misread and a failed or double charge.
Frequently asked questions
Should I buy an Oyster card or use contactless?
Contactless bank card or phone payment works identically to Oyster with the same fares and caps, so most visitors can skip Oyster unless they prefer not to use their own bank card abroad.
Do I need to tap out on buses?
No, buses use a flat fare so you only tap once when boarding; Tube, DLR and Overground require tapping in and out.
What happens if I forget to tap out?
You'll be charged a maximum fare for that journey, which is refunded or corrected once you tap correctly on a subsequent trip.
Is there a daily limit on how much I pay?
Yes, TfL applies a daily cap equal to the cost of a Day Travelcard for the zones used, and a further weekly cap across Monday to Sunday.
Can I use the same contactless card for my whole family?
No, each traveller needs their own card, phone or Oyster card, since fares and caps are calculated per card or device, not per group.
London Congestion Charge & ULEZ 2026: Zones, Costs & Fines
How the London Congestion Charge and ULEZ work: current daily costs, operating hours, zone boundaries and what happens if you don't pay in time.

London Congestion Charge & ULEZ 2026: Zones, Costs & Fines
How the London Congestion Charge and ULEZ work: current daily costs, operating hours, zone boundaries and what happens if you don't pay in time.
Transport · Updated 2026-08-26
Driving into central London means dealing with two separate charging schemes that can both apply on the same trip: the Congestion Charge, which taxes driving in the centre regardless of your vehicle, and the Ultra Low Emission Zone (ULEZ), which taxes older, more polluting vehicles across a much wider area. Both are run by Transport for London (TfL) and are paid separately, even though cameras read the same number plates for both.
The Congestion Charge zone and cost
The Congestion Charge covers a defined zone in central London and costs £18 per day for any vehicle driving within it during charging hours, regardless of how many times you enter or leave that day. It applies every day of the week including weekends and most public holidays, with charging hours generally running through the day and evening, so check current times before you plan a trip.
ULEZ: a much larger zone based on emissions
ULEZ covers a far bigger area, extending across most of Greater London, and charges £12.50 per day for vehicles that don't meet current emissions standards, on top of the Congestion Charge if you're also driving in the central zone. Whether your vehicle is exempt depends on its emissions standard rather than its age alone, so it's worth checking your specific vehicle before driving in, especially with a rental or foreign-registered car.
How and when to pay
Both charges can be paid online, by phone or via the TfL app, and payment for a given day can usually be made in advance or by midnight the following day at the latest. Missing that payment window turns a simple daily charge into a penalty notice, so it's worth paying as soon as you know you've driven into either zone rather than waiting.
Penalties for non-payment
If you drive in the Congestion Charge zone or a non-compliant vehicle in ULEZ without paying by the deadline, you risk a penalty charge notice of £180, reduced to £90 if paid within 14 days. Penalty notices are typically sent to the vehicle's registered keeper, which matters for rental cars and cars registered abroad, since the charge can still catch up with you after you've left the country.
Practical tips for visitors
If you're only in London for sightseeing, using the Tube, buses or walking avoids both charges entirely and is usually faster in central areas clogged with traffic anyway. If you do need to drive — for example picking up a hire car or visiting somewhere transport doesn't reach easily — check both zone maps and your vehicle's emissions compliance before setting off, not after.
Frequently asked questions
How much is the London Congestion Charge?
£18 per day for any vehicle driving within the central zone during charging hours, no matter how many times you enter that day.
How much is the ULEZ charge?
£12.50 per day for vehicles that don't meet the required emissions standard, and it applies across a much wider area of Greater London than the Congestion Charge.
Do I pay both charges if I drive in central London?
Yes, if your vehicle isn't compliant and you drive within the central Congestion Charge zone, both the £18 Congestion Charge and the £12.50 ULEZ charge can apply on the same day.
What happens if I forget to pay?
You risk a penalty charge notice of £180, which drops to £90 if you pay within 14 days; notices are sent to the vehicle's registered keeper.
By when do I need to pay for a day I drove?
Payment is generally accepted from before your trip up until midnight the following day, after which a penalty notice can be issued.

Heathrow & Gatwick to London 2026: How to Get from the Airport
Comparing your options from Heathrow and Gatwick into central London: express trains, Underground, coaches and taxis, with practical tips for choosing.
Transport · Updated 2026-08-26
London is served by several airports, but most visitors arrive through Heathrow, west of the city, or Gatwick, to the south. Both have multiple ways into central London — dedicated express trains, regular rail services, the Underground in Heathrow's case, coaches and taxis — and the right choice depends on your budget, luggage and exact destination.
From Heathrow: Underground, Elizabeth line or Heathrow Express
The Piccadilly line Underground connects all Heathrow terminals to central London, is covered by standard Oyster/contactless pay-as-you-go fares, and is the cheapest option, though it takes the longest and can be crowded with luggage. The Elizabeth line runs faster services from Heathrow into central London and beyond, at a higher fare than the Tube but generally less than the dedicated Heathrow Express, which is the fastest, priciest, non-stop service to Paddington.
From Gatwick: Gatwick Express or regular rail
The Gatwick Express is a non-stop train to London Victoria and the fastest rail option, but ordinary Southern and Thameslink train services also run frequently from Gatwick to Victoria, London Bridge and other central stations at a lower fare with a few extra stops. If your final destination is nearer one of the intermediate stations than Victoria, a regular service can save both time and money compared with the express.
Coaches: cheapest but slowest
National Express and other coach operators run scheduled services from both Heathrow and Gatwick into central London, typically the cheapest option if you book ahead, but journeys take considerably longer than rail and are more exposed to traffic delays, especially at rush hour. Coaches make most sense if you have plenty of time, minimal luggage constraints and want to minimise cost above all else.
Taxis and pre-booked transfers
Black cabs and minicabs are available at both airports but cost significantly more than rail options, and fares can vary with traffic, time of day and whether you use a metered black cab or a pre-agreed minicab fare. Pre-booking a private transfer online in advance often gives a fixed price and guaranteed pickup, which can be worth it with heavy luggage, a late arrival, or when travelling with a group where the total cost splits favourably.
Practical tips for choosing
Check your exact arrival and departure stations against your accommodation, since Heathrow Express and Gatwick Express terminate at Paddington and Victoria respectively, which may not be your most convenient onward connection. Factor in luggage and mobility: express trains and taxis are easier with heavy bags, while the Tube and coaches involve more walking, stairs and waiting, particularly during peak hours.
Frequently asked questions
What's the cheapest way from Heathrow to central London?
The Piccadilly line Underground, paid with the same Oyster or contactless pay-as-you-go fares used across London, though it's also the slowest of the rail options.
What's the fastest way from Heathrow to central London?
The Heathrow Express, a non-stop service to Paddington, though it costs more than the Elizabeth line or the Underground.
Does the Gatwick Express stop anywhere before Victoria?
No, it's a non-stop service to London Victoria; regular Southern and Thameslink trains from Gatwick make additional stops at lower fares.
Are coaches a good option from the airports?
They're usually the cheapest choice if booked ahead, but take considerably longer than rail and are more affected by traffic.
Should I pre-book a taxi transfer?
It can be worth it for a fixed price and guaranteed pickup, especially with heavy luggage, a late flight, or a group splitting the cost.
Public Toilets & Drinking Water in London 2026: Where to Find Them

Public Toilets & Drinking Water in London 2026: Where to Find Them
Where to find public toilets and free drinking water in London: pay toilets, station facilities, Community Toilet Scheme, and Thames Water refill points.
Practical · Updated 2026-08-26
London has relatively few free-standing public toilets compared with other capitals, so knowing where to look saves time. Most visitors rely on a mix of paid facilities in train stations, shopping centres, museums and parks, plus a growing network of free water refill points to stay hydrated without buying bottled water.
Council-run and pay toilets
Many London boroughs operate public toilets in parks, high streets and near tourist sites, though numbers have fallen over the years and a large share now charge a small fee (usually via contactless card or coin, rarely cash-only). Facilities in major parks such as Hyde Park, Regent's Park and Hampstead Heath are generally free, while those in busy central areas near stations or attractions are more likely to charge.
Train and Tube stations
Large mainline stations (King's Cross, Paddington, Victoria, Waterloo, Euston, Liverpool Street) have staffed toilets, almost always requiring a small fee at a turnstile, payable by contactless card. Most Underground stations do not have public toilets at all, so plan around mainline stations or nearby cafés and attractions instead.
Museums, shops and the Community Toilet Scheme
National museums (British Museum, Natural History Museum, Science Museum, Tate Modern) have free toilets open to anyone during opening hours, even if you're not visiting an exhibition, and are one of the most reliable free options in central London. Large department stores, shopping centres and fast-food chains also allow toilet access, generally without needing to buy anything, though some staff may ask. Some boroughs run a Community Toilet Scheme, where local cafés, pubs and shops agree to let the public use their facilities for free or a small charge — look for the scheme's sticker in the window.
Apps and finding the nearest toilet
The Great British Toilet Map (an online, crowd-sourced tool) lists thousands of public and semi-public toilets across the UK including London, with filters for accessible and baby-changing facilities. Google Maps and Citymapper also mark many public toilets and are useful for a quick check while out and about.
Free drinking water and refill points
Tap water in London is safe to drink straight from any tap. Thames Water and other schemes have installed free public drinking fountains and 'refill stations' across parks, high streets and transport hubs — look for blue fountain signage or check the Refill app, which maps thousands of participating cafés, shops and public fountains willing to top up a reusable bottle for free. Many museums and larger stations also have dedicated water fountains near the toilets or entrances.
Frequently asked questions
Are public toilets free in London?
Not always — many council-run and station toilets charge a small fee, usually by contactless card, though facilities in big parks and national museums are typically free.
Do Tube stations have toilets?
Most Underground stations don't have public toilets; it's more reliable to use mainline rail stations, museums or nearby cafés.
Can I use the toilet in a museum without visiting the exhibitions?
Yes, national museums like the British Museum or Natural History Museum have free public toilets open to anyone during opening hours.
Is tap water safe to drink in London?
Yes, tap water is safe everywhere in London and is the same water used to refill bottles at public drinking fountains and refill points.
How do I find the nearest free water refill point?
Use the Refill app or look for blue fountain signage in parks, stations and participating cafés and shops across the city.

London Safety & Practical Tips 2026: Emergency Numbers & Advice
Practical safety tips for visiting London: emergency numbers 999 and 112, NHS 111 non-emergency line, common scams, pickpocketing hotspots and general advice.
Safety · Updated 2026-08-26
London is a large, generally safe capital for visitors, but like any major city it has specific risks worth knowing about, from pickpocketing on crowded transport to common tourist scams. Knowing the right emergency number to call and a few practical habits makes a real difference if something goes wrong.
Emergency numbers: 999 and 112
Dial 999 for police, ambulance, fire or coastguard in a genuine emergency; 112 also works across the UK and connects to the same emergency services, useful if you're used to it from elsewhere in Europe. Both numbers are free to call from any phone, including without credit or a SIM card, and operators can arrange interpreters if you don't speak English.
NHS 111 for non-emergency health issues
For urgent but non-life-threatening health problems — a bad cut, a persistent fever, advice on where to go — call 111 (free) for the NHS non-emergency line, available 24/7, rather than going straight to a hospital's Accident & Emergency (A&E) department. Visitors from outside the UK may be charged for NHS treatment beyond immediate emergency care, so having travel insurance is strongly recommended.
Pickpocketing and common scams
Crowded Tube carriages, mainline stations, markets like Camden or Borough Market, and tourist landmarks such as Oxford Street or the London Eye queue are the areas where pickpocketing is most reported. Keep bags zipped and in front of you, don't leave phones on café tables, and be wary of strangers who create a distraction (spilled drinks, petition clipboards, fake 'gold ring' finds) as a way to get close to your belongings.
Unlicensed taxis and other scams
Only use licensed black cabs (identifiable by their official roof light and license plate) or pre-booked minicabs and ride-hailing apps like Uber or Bolt — never accept a ride from an unlicensed driver touting outside a station or nightclub, as this is illegal and has been linked to serious safety incidents. Be cautious of unofficial 'guides' or ticket sellers near attractions offering skip-the-line deals, and always book tickets through official websites.
General safety habits
London is well-served by CCTV and has a visible police presence in central areas, and violent crime against tourists is relatively rare, but staying alert on public transport late at night and avoiding poorly lit, empty streets is still sensible. Keep a photo or digital copy of your passport separate from the original, and register the UK emergency numbers in your phone before you arrive so you're not searching for them under stress.
Frequently asked questions
What is the emergency number in London?
Call 999 for police, ambulance, fire or coastguard; 112 works too and reaches the same services, both free from any phone.
What is NHS 111 used for?
It's a free, 24/7 non-emergency health line for urgent but not life-threatening problems, helping you decide where to go instead of heading straight to A&E.
Is London safe for tourists?
Generally yes — violent crime against visitors is relatively rare, though pickpocketing on crowded transport and at busy landmarks is a real risk worth guarding against.
How do I know if a taxi is licensed?
Licensed black cabs have an official roof light and visible license plate; otherwise use pre-booked minicabs or apps like Uber or Bolt rather than unlicensed drivers touting for business.
Do tourists have to pay for NHS treatment?
Immediate emergency care is generally provided regardless of insurance status, but visitors from outside the UK may later be charged for further NHS treatment, so travel insurance is strongly recommended.
