Heathrow Airport car hire (LHR) — compare partners

Heathrow is the UK's busiest car hire pickup and every major brand operates here, which makes it one of the few airports where walk-up availability still exists in peak season — rarely at a good rate. Booking two or more weeks ahead typically cuts 20–30% off counter walk-in prices. Most rental desks sit away from the terminals at a dedicated car rental centre reached by free shuttle, so allow 20–30 minutes beyond your arrival time, and more on the return leg if you need to refuel first. Heathrow lies inside the London ULEZ zone; most rental fleets meet the standard, but confirm before collection if you plan to drive into the city. The M4 and M25 are both minutes away, making it the natural start point for Bath, the Cotswolds and the West Country.
