Johannesburg → London (JNB–LHR): six things to know before the overnight

Johannesburg to London is one of the few really long flights that’s easy on the body. You leave in the evening, fly north overnight through roughly the same longitude band, and land in the morning with the clock barely moved. The hard parts are elsewhere: a visa that many South Africans assume has gone away (it hasn’t), and a suitcase packed for the wrong season.

1. You still need a visa, not an ETA

The UK’s Electronic Travel Authorisation gets a lot of press, and it’s easy to assume it applies to everyone. It doesn’t. The ETA is a £20 permission for nationalities that were already visa-free. South Africa isn’t one of them. The UK imposed a visa requirement on South African citizens in 2009, and it’s still a visa national country in 2026, as South African relocation advisers point out to clients regularly.

For a holiday, a family visit or most business meetings, that means a Standard Visitor visa. The numbers from GOV.UK:

• £135 for a stay of up to six months.
• Usually decided within three weeks of your biometrics appointment and documents.
• Apply no earlier than three months before you travel.

The form asks for a lot of history (previous travel, addresses, finances), so leave an evening for it. If you hold a second passport, or UK residence or ancestry status, your answer may be different. Run your details through the official visa checker before paying anyone. Use only GOV.UK; lookalike sites charge more for the same thing.

If you’re going for December, remember that’s peak season at both ends. Apply as soon as your three-month window opens.

2. Your airline decides your terminal

At the time of writing, two airlines fly JNB–LHR nonstop, three times a night between them, according to FlightsFrom and FlightStats. South African Airways and the other names on our JNB–LHR route page come from the historical OpenFlights dataset and aren’t current operators.

Flight	Departs JNB (Terminal A)	Arrives LHR	Aircraft	Scheduled
BA56	19:25	05:35, Terminal 5	Boeing 777-300ER	11h10
VS450	20:15	06:30, Terminal 3	Boeing 787-9	11h15
BA54	21:15	07:30, Terminal 5	Airbus A380	11h15

Summer-schedule times from FlightStats, early October 2026, with London arrivals in BST. The winter timetable that starts when the UK clocks change on 25 October moves the departure times and can change aircraft (FlightsFrom’s winter listing shows later evening departures), so check your own booking.

Terminal 5 and Terminal 3 are a train ride apart, so the terminal matters if you’re meeting someone or booking a car. Getting into town from either: the Heathrow Express to Paddington, the Elizabeth line or the Piccadilly line, all with contactless payment. If you’d rather have someone waiting with a sign after eleven hours in the air, Welcome Pickups Partner does fixed-price Heathrow transfers you book ahead.

3. The overnight is the point, so use it

The great-circle distance is 9,075 km (5,639 mi). Our site’s distance-based estimate is about 11h21 in the air, and the airlines’ early-October schedules show 11h10 to 11h15 gate to gate, slightly less than our estimate. On a very long sector, most of the time is spent at cruise speed, which is faster than the average our rule of thumb assumes. On shorter flights it works the other way.

How to get the most sleep out of it:

• Pick the flight for your bedtime. BA56 at 19:25 leaves early enough that dinner is done by about 21:00 Johannesburg time. BA54 at 21:15 lands latest, which suits people who sleep late anyway or who are going straight to a hotel.
• Eat at the airport and skip the meal service if you’re a light sleeper. You lose a meal and gain about 90 minutes of darkness.
• Choose a seat away from the galleys and toilets. On the A380 and 777 those are the busy, noisy areas.
• Stay up on arrival day. It’s only one or two hours of time difference, so your body clock is fine. You’re tired because of a short night, and the fix is daylight and an early night, not an afternoon nap.

4. One hour or two, depending on the month

South Africa stays on UTC+2 all year. The UK moves between GMT (UTC+0) and BST (UTC+1). In 2026 the UK clocks go back on 25 October and forward again on 28 March 2027. So:

• Late March to late October: Johannesburg is 1 hour ahead of London.
• Late October to late March: Johannesburg is 2 hours ahead.

Two hours is still nothing physically. Where it catches people out is scheduling: a 09:00 London call is 11:00 in Joburg in winter, not 10:00. If you work across both countries, our time-zone explainer is worth a read, and the UK country page shows the current local time.

5. Pack for the opposite season

The two cities are in opposite hemispheres, so their seasons are reversed. A highveld summer December is a dark, damp London winter, and London’s July is warm while Johannesburg’s is cold and dry.

The packing rules that follow:

• December–February trips: London averages highs of about 8–9 °C, with short days. Bring a proper coat, not a Joburg winter jacket over a T-shirt. Waterproof shoes help more than an umbrella.
• June–August trips: London is the warm one, with highs in the low to mid 20s. You’re leaving a cold highveld winter, so travel in layers and peel them off at Heathrow.
• April and October: the two cities are closer, but London is still the cooler and damper of the two. A light rain jacket earns its space.

6. Rands, pounds and plugs

Plugs. South Africa uses Types C, M and N; the UK uses Type G, both around 230 V and 50 Hz. You need an adaptor, but not a voltage converter, for phones and laptops. Our UK plug adaptor guide covers which ones are worth buying.

Money. London is close to cashless. Contactless cards work on the Tube, buses and most shops. Use a card with low foreign transaction fees; our travel money card comparison covers the options. The currency page has today’s ZAR–GBP rate. If you’re carrying a lot of cash for any reason, the UK requires you to declare £10,000 or more on arrival.

Insurance. The UK’s NHS isn’t free for most visitors, and getting sick abroad is expensive, so buy cover before you fly. SafetyWing Partner is one option; check the medical limits and exclusions.

Data. A UK eSIM installed in Johannesburg means your phone works at Terminal 5 or 3 straight away. Airalo Partner has UK plans.

Our LHR airport page has more on the arrival end. If you’re flying in from West Africa instead, the Lagos to London guide covers that route.
