Drivers approaching Heathrow Airport via the M25 motorway need to use specific junctions depending on their intended terminal. Heathrow's official driving guidance states that M25 Junction 14 is the recommended exit for Terminals 4 and 5. For Terminal 4, drivers should exit at Junction 14 and follow signs for the A3113 towards Heathrow Airport and Terminal 4, then proceed via the Southern Perimeter Road. The postcode for Terminal 4 is TW6 3XA.

Routes for Terminals 2 and 3
The recommended route changes for passengers travelling to Terminals 2 and 3. These terminals are accessible by exiting the M25 at Junction 15 and joining the M4 eastbound towards London. Drivers should then leave the M4 at Junction 4 and take the airport spur road leading to Terminals 2 and 3. Heathrow specifically provides this route for its terminal parking facilities at these terminals. The postcodes are Terminal 2: TW6 1EW and Terminal 3: TW6 1QG.
Heathrow's general driving advice consolidates that Terminals 4 and 5 are reached from M25 Junction 14, while Terminals 2 and 3 are accessed via M25 Junction 15 followed by M4 Junction 4. However, routes can vary depending on specific car park bookings. For instance, some parking serving Terminals 2 and 3 may use Junction 14 via the airport's perimeter roads. Passengers are therefore advised to check their booking confirmation and follow airport signage for their precise destination.
