Heathrow Location

Heathrow is about 14 miles (22km) west of Central London, just off the M25 and M4 motorways. 

Reaching Heathrow by road

Terminals 1, 2 and 3 can be reached via the M4 (leave at Junction 4), the M25 (Junction 15) and the A4. Postcodes (for sat-nav) are as follows:

  • Terminal 1: TW6 1AP

Terminal 5 is on the airport’s Western Perimeter Road and has its own separate access road, which you can get to from junction 14 of the M25. If you’re approaching via the M4, leave the motorway at junction 4b and follow the M25 south to junction 14. The postcode for Terminal 5 is TW6 2GA. 

Setting down passengers

You can stop on the terminal forecourt roads to set down passengers, but if you need to stop for any other reason you should use the car park. If you do leave your car unattended on a forecourt road, it could be towed away and you will have to pay a charge to have it released. 

Petrol stations

By taxi

London’s licensed black cabs serve Heathrow, and you should easily be able to find a taxi outside any of the terminals. For information on taxis, simply visit an information desk within a terminal. 

Don’t be tempted to use an unmarked cab, or to take up the offer of a taxi from someone who approaches you inside the terminal. These are likely to be unlicensed (and illegal) operators. Transfers Only ( is a premium service offering chauffeured travel to and from airports including Heathrow.
