Heathrow Terminal 3
Taxi Transfers

Customs and immigration clearance time at Heathrow Terminal 3 depends on your passport, eGate eligibility, and how busy the airport is. As a general estimate for 2026: eGate users typically clear in 15–30 minutes; during normal periods expect 30–60 minutes; busy international arrival windows can take 60–120 minutes; and at peak congestion, clearance may exceed 2 hours. The worst periods are typically 6:00 AM–10:00 AM when multiple long-haul overnight flights arrive together. GAT includes 60 minutes of free waiting time from your actual landing time to cover most scenarios.

Terminal 3 experiences three main peak periods each day. The morning rush (5:30 AM–9:30 AM) is typically the busiest — many overnight long-haul flights from North America, the Middle East, and Asia all arrive around the same time. A midday peak occurs between 11:30 AM and 3:00 PM for European and connecting services, and an evening rush runs from 5:00 PM to 8:30 PM as major long-haul inbound flights return. For arrivals immigration, 6:00 AM–10:00 AM is the most congested window. If you are collecting a passenger, plan for potential delays during these hours.

The smoking area at Heathrow Terminal 3 is located in designated outdoor areas directly outside the terminal entrance on the departures forecourt level. To reach it, exit the Terminal 3 building and walk to the marked smoking points in the forecourt. You must smoke before entering security — there are no smoking areas airside at T3. If you pass through security first, you cannot smoke without leaving the secure zone and re-clearing security, which may put your flight at risk.

No. There are no smoking or vaping areas after security (airside) at Heathrow Terminal 3. Smoking is only permitted in designated outdoor areas before security on the landside forecourt. If you have already passed through security, you would need to leave the secure area and re-queue through security to smoke — this is strongly not recommended if your flight departs within a few hours. Always smoke before check-in or security, especially on long-haul flights.

The drop-off charge at Heathrow Terminal 3 in 2026 is £7 per entry. The drop-off zone is directly outside Departures, with a maximum stay of 10 minutes. There are no barriers or tickets — ANPR cameras automatically record number plates and payment must be made online or by phone by midnight the following day. Vehicles left unattended or exceeding the 10-minute limit may face additional penalties.

There is no free drop-off directly at the Terminal 3 forecourt — the standard charge is £7 per entry. However, there is a free alternative: use the Heathrow Park & Ride (Long Stay) facility. Drivers can drop passengers there at no charge, and passengers then board a free shuttle bus directly to Terminal 3. This is the most cost-effective option if you want to avoid the drop-off fee entirely.

Heathrow Terminal 3 and Terminal 5 are approximately 4–5 km (about 2.5–3 miles) apart by road. Terminal 5 is located to the west of the airport, while Terminal 3 is in the central terminal area. They cannot be reached on foot — you must use the Heathrow Express, the free inter-terminal shuttle bus, or a taxi/private hire vehicle to travel between them. Transfer time is typically 15–25 minutes depending on the method used.

There are three ways to transfer from Heathrow Terminal 3 to Terminal 5. The free inter-terminal shuttle bus departs from the ground level of T3 and runs regularly throughout the day — journey time is around 15–20 minutes. Alternatively, the Heathrow Express train connects the terminals in approximately 7–10 minutes (a fee applies). For passengers with heavy luggage or requiring a more direct service, a pre-booked private hire taxi is also a convenient option. Always allow at least 30 minutes for transfers, plus additional time for re-clearing security at Terminal 5.

Heathrow offers several inter-terminal transfer options. The free Heathrow shuttle bus connects all terminals (T2, T3, T4, and T5) from the arrivals and ground levels and runs throughout terminal operating hours. The Heathrow Express rail service provides a faster link between Terminal 5 and the central terminals (T2/T3), though a fare applies. The Piccadilly line underground also connects all terminals. For passengers connecting between flights, check whether your airline operates an airside transfer — this can save the time needed to exit and re-enter security.

For most passengers, the free Heathrow inter-terminal shuttle bus is the easiest and most straightforward option — it is free, signposted clearly from every terminal, and requires no booking. It connects T2, T3, T4, and T5. If you are travelling between T3 and T5 and have the Heathrow Express available, this is the fastest route (under 10 minutes). For passengers with significant luggage, a pre-booked private transfer directly between terminals can be the most comfortable and stress-free solution, especially during busy periods.
