How long does it take to drive to Heathrow?

Driving to Heathrow takes around 45-60 minutes from central London, depending on traffic and your starting point. Allow extra time during rush hour, school holidays and on the approach roads near the airport, which can be congested at peak times.

As a guide, the drive to Heathrow is around 45-60 minutes from central London, though this varies with traffic, time of day and where you set off from. Peak periods, weekday rush hours, Friday evenings and the start of school holidays, can add significant time, particularly on the M4 (J4) from the east and west and the final approach. Always build in a buffer so you arrive relaxed, and factor in time to park and transfer to the terminal. Pre-booked parking removes the stress of finding a space on arrival; compare options with us and apply BCP30.

Are there roadworks or closures near Heathrow?

Roadworks and closures near Heathrow change regularly, so check live traffic before you set off. The main approach is the M4 (J4) from the east and west, where any works can cause delays at peak times.

Roadworks and closures around Heathrow vary from week to week, so it is worth checking a live traffic service or your sat-nav's real-time data on the day. The key approach, the M4 (J4) from the east and west, is the route to watch, as works there can back up traffic during busy periods. National Highways and local travel sites publish current roadworks. Allowing extra time and having an alternative route in mind helps you avoid missing check-in. Pre-booked parking means your space is guaranteed whenever you arrive, with BCP30 applied.

Is there a free drop-off at Heathrow?

Heathrow drop-off costs £7 for a 10-minute maximum stay (free at the Long Stay / Park & Ride car parks with a free shuttle). If you are dropping a passenger rather than parking, use the free alternative to avoid the forecourt charge; if you are parking for a trip, pre-booked parking is better value.

For drop-offs, Heathrow charges £7 for a 10-minute maximum stay (free at the Long Stay / Park & Ride car parks with a free shuttle). The free alternative trades a short shuttle or walk for avoiding the forecourt fee, worth it especially for a return drop-off and pick-up. If, however, you are the driver parking your own car for a trip, a drop-off zone is not the right option, pre-booked Park & Ride or Meet & Greet is far better value and keeps your car secure for the whole trip. See our Heathrow drop-off charges guide for the detail, and compare parking below with BCP30.
