The 8 Best Car Rental Companies at London Heathrow (2026)

Enterprise is the default right answer at Heathrow for most travellers. It has desks in every terminal, the friendliest payment policy of the majors — debit cards accepted for most classes — and a network deep enough that one-way rentals (land at Heathrow, drop in Manchester) don't require heroics.

Two caveats. Airport desks aren't open 24 hours for pickups — late arrivals use the key-drop returns — and driving onward to Ireland or the continent requires buying the £325 European Travel Coverage at the desk. National and Alamo bookings are served from the same counter, so rank them together.

Sixt is the only operator at Heathrow with an honest in-terminal counter — Terminal 2 arrivals, level 1, returns to the T2 Short Stay Car Park. For anyone who values walking out of the door and into a near-new car over saving £30, it's the smoothest experience at LHR.

The fleet is premium: BMW, Audi, Mercedes and electric models that make the other desks look dated. The price matches the positioning — it's rarely the cheapest — and if you pay by debit, the deposit (rental + £300) is actually debited and refunded, which hits your cash flow harder than a hold.

Green Motion is the value play at Heathrow: base rates materially below the majors, a low-CO2 and electric-heavy fleet, and a straightforward pickup from the Holiday Inn M4/J4 with its own shuttle. If your priority is the cheapest honest rate and you don't mind a shuttle, it wins on price.

The catch is the deposit: a physical Visa/Mastercard credit card in the main driver's name is required, debit cards can't secure the hold (unless you buy full waivers at the desk), and releases take 7–10 business days — up to 30 with some issuers. UK renters must bring a DVLA licence check code.

Hertz is the familiar brand for international arrivals, with Gold Plus Rewards fast-lane service and a large fleet including vans. The T3 helpdesk gets you paperwork done, then the shuttle takes you the short hop to the Northern Perimeter Road park.

The deposit structure is the harshest at Heathrow among the majors: without SuperCover, you're held for the rental cost plus fuel plus a further £500. Buy SuperCover and the hold drops to extras + fuel or £200. Dollar and Thrifty bookings are served from the same operation.

Avis is the solid middle of the Heathrow market: desks in three terminals, the Avis Preferred skip-the-counter programme, and reasonable debit-card acceptance (Visa/Mastercard debit, no Maestro or prepaid). High-value vehicles may demand two cards, one of them credit.

The catch is logistics: all pickups route through the Northrop Road main station by shuttle, and the T5 desk has moved to the Holiday Inn with a bus-stop-25 pickup — worth confirming which terminal you're flying from before booking.

Europcar works from the Northern Perimeter Road West centre like Hertz, with a wide fleet including vans and people carriers. The deposit is one of the friendlier structures at Heathrow: £250 if you've prepaid, rental plus £250 otherwise.

Like every off-airpark operator here, you'll shuttle to collect — fine if you expect it, annoying if you assumed 'desk at Heathrow' meant walking out with the car. Keddy budget bookings are served from the same centre.

U-Save (owned by Green Motion since 2022) is the deepest-discount option at Heathrow. It shares operational DNA with Green Motion — same credit-card-only deposit policy, same shuttle model — and occasionally undercuts even Green Motion's rates.

Counter experiences vary; Trustpilot reports of £2,000–£3,000 holds and upsell pressure at airport counters mean it's worth confirming your exact deposit before you commit. If price is genuinely the only factor, it can win.

Drivalia is the Spanish long-term rental brand now at major UK airports, with an economy-and-EV fleet and a hotel-desk model. At Heathrow it's the least established presence — good for low weekly rates on economy cars, thinner for premium classes and vans.

Best suited to longer rentals where the weekly rate advantage compounds. For a two-day city trip, the majors' convenience wins.
