London to Singapore (LGW–SIN) — Airlines, Schedules & Connections

British passport holders enter Singapore visa-free for up to 90 days. No fee, no advance application. Passport must be valid for at least 6 months beyond the date of entry. Complete the SG Arrival Card (SGAC) online at eservices.ica.gov.sg within 3 days before arrival. This replaced the old paper disembarkation card.

You need proof of onward travel. Immigration at Changi Airport (SIN) is fast, with automated gates available for repeat visitors. Extensions beyond 90 days require an application to the Immigration and Checkpoints Authority (ICA) before your current stay expires. Working or conducting business beyond meetings requires a separate employment or work pass.

Singapore enforces strict laws: chewing gum import, littering, jaywalking, and drug offenses carry heavy fines or criminal penalties.

The Gatwick Express runs non-stop from London Victoria to the South Terminal in 30 minutes, with trains every 15 minutes (from £21.50 one-way; advance fares cheaper online). Thameslink trains from London Bridge, Blackfriars, City Thameslink, and Farringdon are slower (35–45 min) but significantly cheaper; often £10–13 on Oyster or contactless. Southern trains also serve the route.National coaches (National Express, Megabus) connect Gatwick to Victoria Coach Station for £6–15. Taxis from central London cost £70–100+ depending on traffic. Driving via M23 and A23 takes 35–60 minutes; multi-storey car parks are directly connected to both terminals by a 2-minute monorail shuttle.

MRT from T1/T2/T3 to City Hall takes about 30 minutes (S$2.20–2.50 with EZ-Link card). Trains run from 5:31am to midnight. For Terminal 4, take the free inter-terminal shuttle bus to T2 first.

Taxis from arrivals cost S$20–35 to Orchard or Marina Bay, including airport surcharge (S$5) and possible peak surcharges. Grab is cheaper and very reliable in Singapore. Coach buses serve Johor Bahru (Malaysia) from the airport.

Equatorial climate with no true seasons, hot (26–33°C) and humid year-round. Changi is one of the most reliable airports in Asia for flight operations: thunderstorm cells are intense but brief, typically clearing within 1–2 hours. Most delays are weather-related and short.

Northeast monsoon (November–January) brings the most consistent rain, sometimes for days at a time. Haze from Indonesian forest fires (typically August–October) occasionally reduces visibility and triggers air quality warnings, but rarely grounds flights. Changi's operational efficiency means it handles weather disruptions better than most airports its size.
