Singapore and London sit about 10,900 km apart, and a nonstop flight covers that distance in roughly 13 to 14 hours. This Singapore to London flight guide is for anyone booking the trip in late 2026 or early 2027.
It covers which airlines fly nonstop, how long the flight takes, and when fares tend to drop. You will also find the UK entry rules for Singaporeans and the cheapest ways into central London. We checked every price and schedule in October 2026, so confirm the details again before you pay.
Three airlines fly nonstop from Singapore to London: Singapore Airlines, British Airways, and Qantas. The flight takes about 13 to 14 hours, and most planes leave Changi in the morning or near midnight. Singapore citizens also need a UK travel permit called an ETA, which costs about S35in2026.EconomyreturnfaresaveragedaboutS944 in February, the cheapest month in Kayak’s data.
Direct flights from Singapore to London in 2026
Singapore Airlines, British Airways, and Qantas are the only carriers that fly nonstop between Changi Airport and London this year. The national airline runs the most flights, with four a day to Heathrow and a growing service to Gatwick. British Airways flies twice a day to Heathrow, and Qantas flies once a day on its Sydney to London route through Singapore.
The table below lists each nonstop option, based on airline schedules published for 2026:
| Airline | London airport | Flights from Singapore |
| Singapore Airlines | Heathrow (LHR) | 4 daily |
| Singapore Airlines | Gatwick (LGW) | 10 weekly, 14 weekly from 25 Oct 2026 |
| British Airways | Heathrow (LHR) | 2 daily |
| Qantas | Heathrow (LHR) | 1 daily |
In London, Singapore Airlines uses Heathrow Terminal 2 and the Gatwick North Terminal, while British Airways lands at Terminal 5. Qantas flights arrive at Heathrow Terminal 3.
Every Singapore to London flight guide should mention that Gatwick can be the cheaper airport. Kayak found a return fare of S$763 to Gatwick, the lowest of any London airport in its route data. The Gatwick flights use the Airbus A350, while two of the daily Heathrow flights still use the double-deck Airbus A380.
At Changi, British Airways and Qantas check in at Terminal 1, and Singapore Airlines usually leaves from Terminal 3. Check your e-ticket a day before you fly, because the airport can move a flight to a new terminal. If you want the widest choice of times, pick the national airline. It runs five or six London flights on most days.
One-stop flights add a few hours to the trip, but they can save you real money. Finnair connects through Helsinki, and its quickest option takes about 16 hours 45 minutes including the stop. Cathay Pacific routes through Hong Kong in about 18 hours 45 minutes from gate to gate. Booking sites often list China Southern and China Eastern as the lowest fares, with a stop in mainland China.
How to plan your trip with this Singapore to London flight guide
Good planning comes down to five choices: flight time, booking date, papers, arrival airport, and sleep. The parts below take each one in turn, so you can use this Singapore to London flight guide as a simple plan. Start with the flight time, since it shapes almost every other choice you make. Each part gives you the real numbers you need to make that choice today.
Singapore to London flight time and time difference
A nonstop Singapore to London flight time runs from about 13 hours 55 minutes to 14 hours 30 minutes. The exact time depends on the airline, the plane, and the winds on the day you fly. Flights back to Singapore are often shorter, at around 12 hours 40 minutes to 13 hours 25 minutes. Planes heading east get a push from the jet stream.
London runs 7 hours behind Singapore while the UK is on British Summer Time. From 25 October 2026, when UK clocks go back, the gap grows to 8 hours until late March. That is why flights that leave Changi near midnight land in London around breakfast time. British Airways flight BA12, for example, leaves at 11:25 pm and reaches Heathrow Terminal 5 at 6:35 am. So if you leave on a Monday night, you land in London early on Tuesday morning.
When to book cheap flights from Singapore to London
The cheapest month for this route is usually February, when Kayak recorded an average economy return of S$944. Cheapflights data points to July as the most costly month, which lines up with school holidays in Europe. Booking sites do not fully agree, so treat these months as a guide rather than a firm rule.
The day you fly matters a little too, though far less than the month you pick. Kayak’s Singapore data shows Saturday as the priciest day of the week to fly out. Set a fare alert on two or three booking sites, then watch prices for a few weeks before you pay. Book with the airline itself when you can, because changes are easier to sort out than through an agent.
If you collect KrisFlyer miles, check the Gatwick flights before you look at Heathrow. The frequent flyer blog Mainly Miles says the Gatwick route may have better Business Class award space than Heathrow.
UK ETA for Singaporeans and other travelers
Singapore passport holders can visit the UK without a visa, but they must hold an Electronic Travel Authorisation (ETA) before they board. The fee rose to about S$35 on 8 April 2026, and one approval covers many visits over two years. You can apply through the official app or website in five short steps:
- Download the official UK ETA app, or open the ETA page on GOV.UK.
- Scan the chip in your passport and take a photo of your face.
- Answer the questions about your trip and any criminal convictions.
- Pay the fee of about S$35 with a debit or credit card.
- Wait for the decision by email, which usually arrives within minutes.
Every traveler needs their own ETA, and that includes babies and young children. Skip third-party agents, since some charge two to three times the official fee for the same form. Apply at least three working days before you fly, in case your form needs a manual check.
Getting from Heathrow or Gatwick to central London
The cheapest way from Heathrow to central London is the Piccadilly line, and the fastest is the Heathrow Express. All three rail options take contactless cards and phone wallets, so you never need a paper ticket. Based on one-way fares from March 2026, the Piccadilly line costs about S$10 and takes 50 to 60 minutes.
The Elizabeth line costs about S27andreachescentralLondonin30to35minutes.TheHeathrowExpresscostsaboutS43 for a standard ticket and gets to Paddington in 15 minutes. A black cab runs about S105toS175, depending on traffic and where you stay.
For most people, the Elizabeth line gives the best mix of price and speed. It runs straight under the city, so you can often skip a change at Paddington. The Piccadilly line suits budget travelers with light bags, though the ride takes close to an hour. It also runs all night on Fridays and Saturdays, which helps if your flight lands late.
Gatwick sits about 40 km south of the city, and the Gatwick Express reaches London Victoria in about 30 minutes. A good Singapore to London flight guide reminds you to plan this last leg. A cab after a 14-hour flight costs much more than most people expect.
How to sleep on the flight and beat jet lag
Most overnight flights land between 5 am and 7 am. The goal is to sleep on board, then stay awake until evening. These habits help on a 14-hour flight:
- Pick a flight near midnight if you want to land in the morning.
- Set your watch and phone to London time as soon as you board.
- Skip the first meal if it falls during London’s night hours.
- Drink water every hour and keep alcohol to one drink.
- Choose a window seat so seatmates do not wake you.
- Spend your first afternoon outdoors, since daylight resets your body clock.
The national airline also runs a morning flight from Changi that lands at Heathrow in the afternoon. That timing suits people who cannot sleep on planes, because you go to bed at a normal London hour. Either way, try to stay awake until 9 pm on your first night, even if you feel tired by lunch.
Singapore to London flight guide checklist before you fly
Run through this list two days before you leave home for Changi. A missing paper causes far more stress at the check-in desk than a heavy bag does:
- Passport valid for your whole stay, linked to an approved UK ETA.
- Return or onward ticket saved offline on your phone.
- London hotel address, written down for the airline and border officer.
- Contactless bank card or phone wallet for the Tube and buses.
- Travel insurance policy number and the insurer’s 24-hour helpline.
- A warm jacket in your carry-on for cold London mornings.
- Any medicine you take, in its first box, with a copy of your doctor’s note.
You can leave the plug adapter at home, because Singapore and the UK both use the three-pin Type G socket. Singapore citizens can also use the eGates at Heathrow and Gatwick, which tend to move faster than the staffed desks. Families with young children should join the staffed lanes, since the gates have age limits. Keep a screenshot of your ETA email too, in case the airline system is slow at the desk.
Frequently asked questions
Which airline is best for a Singapore to London flight?
Our pick in this Singapore to London flight guide is Singapore Airlines, because it has the most daily flights and serves both Heathrow and Gatwick. British Airways suits oneworld members who want to earn Avios on the trip. Qantas works well for travelers already flying from Australia through Singapore. Fares on all three often sit close together, so the schedule you prefer usually decides it.
How far is London from Singapore by plane?
The flight distance from Singapore to London is about 10,855 km, or roughly 6,750 miles. That makes it one of the longest nonstop routes you can fly from Changi Airport. For scale, Singapore to Sydney is about 6,300 km, so the London flight covers close to double that. Plan for a full day of travel once you add check-in and the ride into town.
Do Singapore residents on other passports need a UK visa?
It depends on your passport, not on where you live. Singapore permanent residents and Employment Pass holders follow the rules for the country that issued their passport. Malaysian, Australian, and American citizens need an ETA, just like Singaporeans do. Indian, Chinese, and Filipino citizens need a Standard Visitor visa instead. Check the GOV.UK visa tool with your exact passport before you book.
Does Singapore Airlines fly the A380 to London?
Yes, the airline runs two daily Airbus A380 flights between Changi and Heathrow. The other two Heathrow flights use the Boeing 777-300ER, and on the A380, Business Class sits on the upper deck. The Gatwick service uses the smaller Airbus A350, which has 253 seats across Business, Premium Economy, and Economy.
What changes should travelers watch for after October 2026?
Watch for three changes that take effect from late October 2026 onward. Singapore Airlines moves its Gatwick service to twice daily from 25 October, and UK clocks go back that same day. The ETA fee has risen twice since 2025, so check GOV.UK before you apply. We update this Singapore to London flight guide whenever schedules or fees change.
Conclusion
The best Singapore to London flight for most people is a late-night nonstop on Singapore Airlines or British Airways. You land around breakfast, clear the eGates, and reach central London by mid-morning on the Elizabeth line.
Use this Singapore to London flight guide to lock in three things: the ETA, the arrival airport, and a fare alert. Those three cost the most when people miss them. Your next step is to apply for your ETA on GOV.UK today, at about S$35. Then set a fare alert for February if your dates can move, and bookmark this Singapore to London flight guide for updates.
