London to Gatwick: The M23 Route, Timing & Transfer Fares Explained (2026)

Cruise ship berthed alongside a passenger terminal

The London–Gatwick run is one of the UK's busiest airport routes, and getting the timing right can be the difference between a relaxed journey and a white-knuckle dash. This guide focuses on the road itself — the M23 corridor, where and when traffic builds, how long the trip really takes at different hours, and exact fixed-price transfer fares so you can plan a calm, on-time arrival.

The Route: How London Connects to Gatwick

Gatwick lies around 28 miles south of central London. The standard driving route heads south out of the city via the A23, joining the M23 motorway around Coulsdon and Merstham, then running straight down to the airport at Junction 9. For most central-London pickups, the journey is 45–90 minutes depending entirely on the time of day.

The M23 Corridor

The M23 is a short but critical motorway — it links the M25 (London's orbital) at Junction 7 down to Gatwick. Because it's the main artery to the airport, congestion clusters at two predictable points: the M25 interchange, where orbital traffic merges, and around Redhill and Merstham during peak commuter hours.

Peak windows: 6:30–9:30am and 4:00–7:00pm add 20–40 minutes to the journey. Departures before 6am are consistently the fastest.

The A23 Approach

Before the motorway, the A23 threads through south London — Brixton, Streatham and Croydon. This urban stretch is where early congestion appears, so even a clear M23 can be slowed by a busy A23 at rush hour. South London pickups skip much of this.

Real Journey Times by Time of Day

Timing is everything on this route. Here's what to realistically expect from a central-London start:

Departure TimeCentral London → GatwickNotes
Before 6:00am45–55 minClear roads, fastest run
7:00–9:30am (peak)75–95 minHeavy commuter traffic
Midday55–70 minModerate, predictable

⚠️ Timing rule: For a 7am flight, work backwards: arrive by 4am (long-haul) → pickup by 2:45am. A fixed-price transfer means that pre-dawn slot costs exactly the same as midday — no surge, no penalty for travelling early.

Heathrow to Gatwick: The Trickiest Leg

One of the most-searched Gatwick routes isn't from London at all — it's from Heathrow. There's no direct train, so public transport means changing in central London, a 90-minute-plus ordeal with luggage. By road, the two airports are ~26 miles apart via the M25 anticlockwise, typically 45–90 minutes.

💡 M25 buffer: The Heathrow–Gatwick leg uses the M25's busiest section. If you have a tight connection, add a 45-minute buffer during peak hours. A saloon on this route runs about £66 one-way.

Step-by-Step: Timing Your Gatwick Run

Step 1: Fix Your Arrival Target

2 hours before short-haul, 3 hours before long-haul, plus 30–60 minutes in peak season.

Step 2: Add Journey Time

Use the time-of-day table above — a 5am journey is far quicker than an 8am one.

Step 3: Add a Buffer

30 minutes for normal conditions; 45+ if your route uses the M25 at peak hours.

Step 4: Book Ahead

At least 24 hours. You'll get SMS confirmation with driver and vehicle details.

Choosing the Right Vehicle for the Journey

The right vehicle depends on your group size and luggage. On the Gatwick run specifically, boot space matters — airport luggage plus hand baggage fills a saloon quickly for four people.

Saloon (Mercedes E-Class, BMW 5)42 large + hand luggageSolo travellers, couples
Executive (premium saloon)32 large + hand luggageBusiness, comfort-first trips
MPV (7-seater)65+ large casesFamilies, small groups

The Bottom Line

The M23 is quick off-peak and slow at rush hour — plan around it. A fixed-price, flight-tracked transfer removes surge risk and gets you door-to-door on your schedule, whether you're leaving from central London or connecting from another airport.
