✅ Follow-up question

Would you like recommendations tailored to specific UK cities (London, Edinburgh, Manchester), or help comparing prices for your travel dates?

These are the main car hire companies used in the UK, based on Which? and branch-count data.

Top picks

1. Arnold Clark Rental: best for service and value

• Which? names it as its recommended UK provider. If you're hiring in the UK, it recommends Arnold Clark Rental.
• It scored 82% in the Which? ratings.
• It's a UK-only firm. Another guide calls it the safest choice and says it handles damage claims fairly, based on actual evidence.

2. Enterprise: best for local branches

• Enterprise Rent-A-Car is the largest car rental company in the UK in 2026, with 441 locations by one count.
• It suits you if you want a high-street branch near home, such as for a weekend hire or a replacement car.

3. Hertz: best for airports and loyalty perks

• Hertz has 371 UK locations.
• What Car? ranked it first in its comparison, though that article is a couple of years old. It found Hertz had the lowest cost for Cardiff and the second lowest for Heathrow, and free Gold Plus membership would have cut those prices by 10%.

4. Europcar: good for budget hire and London stations

• Europcar has 146 UK locations.
• It has pick-up points at Heathrow, Gatwick, Kings Cross, Victoria and St Pancras.

5. Sixt: good if you want a premium car

• Sixt specialises in premium and luxury vehicles.
• It has fewer UK branches than the others, at roughly 20 or more.

6. Avis

• It's a reliable, well-established option, and one guide calls it "The Reliable Fallback."
• It has far fewer UK branches than Enterprise or Hertz, at about 53.

Other options

• Alamo, Thrifty and Dollar are often cheaper. Alamo is Which?'s pick for the USA, not the UK.
• Green Motion can be cheap, but What Car? found its deals had some big limitations.
• Drivalia is a contactless option in London and other cities.
• Zest Car Rental is a broker Which? recommends. It is a Which? Recommended Provider. It's most useful for hiring abroad.

Tips

• Check the fuel policy and the excess. Which? warns that some big names charge hundreds of pounds for insurance you don't need.
• Take dated photos of the car at pick-up and drop-off.
• Compare prices across a few companies. Rates vary a lot by location and date.

For the best balance of service and fair treatment, start with Arnold Clark. If you want the most branches, or a one-way hire, try Enterprise or Hertz.

In the UK, “car hire” is the usual term. There’s no single “best” company because airport vs local branch, van vs car, and budget vs premium change the answer. But for most UK renters, these are the brands people actually use and are worth shortlisting:

If I were booking a normal UK trip, I’d compare Enterprise, Arnold Clark and Europcar first, then check Avis/Budget and Hertz/Thrifty if picking up at an airport. For a premium car, I’d look at Sixt. For a cheap airport hire, I’d only use Green Motion/Easirent if the saving is large and I’ve checked the specific branch’s recent reviews.

UK booking tips:

• Compare via Rentalcars.com, Skyscanner, Kayak or DiscoverCars, but book direct if the price is similar.
• Check the excess/deposit hold, fuel policy, mileage limits, young-driver surcharge, airport surcharge and one-way fee.
• UK licence holders may need a DVLA check code/share code; bring your photocard licence and a credit/debit card in the driver’s name.
• Buy standalone car-hire excess insurance separately if you want cover—usually much cheaper than the counter upsell.
• Remember ULEZ, Congestion Charge and parking fines are not included. Take photos/video of the car at pickup and return.

When renting a car (or "car hire") in the UK, the best option depends on whether you're picking up at an airport, driving around a major city, or looking for local branch availability.

Independent consumer groups (like Which?) consistently rate UK car rental providers based on price transparency, customer service, and vehicle condition. Here are the top brands and services actually used and trusted across the UK.

---

1. The Overall Best & Most Trusted

• Arnold Clark Car & Van Rental
  • Best for: Transparent pricing, value for money, and travel in Scotland & Northern/Central England.
  • Why it’s top: Arnold Clark regularly tops consumer surveys in the UK. They are known for transparent pricing with no hidden surprises, clear rental terms, and straightforward customer service. Their fleet is modern, and they cover most major cities and transport hubs.
• Enterprise Rent-A-Car
  • Best for: Customer service, suburban coverage, and convenience.
  • Why it’s top: Enterprise is the most widely available car hire brand in the UK. Unlike competitors that stick to airports, Enterprise has locations in almost every medium-to-large UK town. Their signature service—picking you up from your home or local train station—is a huge plus.

---

2. Best for Premium Fleets & Airport Pickups

• Sixt
  • Best for: Newer, higher-spec, and luxury cars.
  • Why it’s top: If you prefer driving a premium German brand (BMW, Audi, Mercedes-Benz) rather than a base-spec hatchback, Sixt offers one of the youngest and best-equipped fleets in the UK. They have a major presence at all primary UK airports (Heathrow, Gatwick, Manchester, Edinburgh, etc.).
• Avis & Hertz
  • Best for: Frequent flyers and business travellers.
  • Why it’s top: Reliable, established global brands with large desks at major airports and railway hubs. Prices can be slightly higher, but loyalty members often bypass the queues, which can be long during peak holiday seasons.

---

3. Best App-Based & Contactless Car Hire

• Virtuo
  • Best for: Frictionless, desk-free rentals in major cities (London, Manchester, Edinburgh).
  • Why it’s top: Virtuo eliminates the traditional rental desk entirely. You register via the app, locate your car at a dedicated parking bay (often in city-centre car parks or train stations), and unlock it with your phone 24/7. Vehicles are premium (like Mercedes A-Class or GLA), spotlessly clean, and mileage limits are generous.

---

4. Best Broker for Finding Deals Safely

• Zest Car Rental
  • Best for: Comparing prices without getting caught in cheap-broker scams.
  • Why it’s top: While comparison sites (like Rentalcars.com or Skyscanner) pull from everywhere, Zest is the only broker officially recommended by UK consumer advocates (Which?). They vet local operators, include excess protection as standard, and clearly lay out terms so you aren’t hit with unexpected charges at the counter.

---

5. Short-Term City Rentals (Car Clubs)

If you only need a car for a few hours or a day trip while staying in a city:

• Zipcar: Dominates London and select university cities. Offers pay-by-the-minute, hour, or day options, with fuel and London Congestion Charge/ULEZ fees included.
• Enterprise Car Club: Similar to Zipcar, with vehicles parked on dedicated street bays across major UK towns and cities.

Tips for Hiring a Car in the UK

1. Manual vs. Automatic: Manual transmission is the standard default in the UK. If you need an automatic, specify this when booking and book early, as they are in higher demand and cost more.
2. Decline Desk-Side Excess Insurance: Car rental desks will try to sell you expensive "excess waiver" insurance (often £15–£25/day). Instead, buy an independent standalone Car Hire Excess Insurance policy online (from providers like Leisure Guard, Direct Car Excess, or ReduceMyExcess) for around £3–£6 a day before you pick up the car.
3. Watch out for ULEZ and Clean Air Zones: Most modern hire cars are fully compliant with London’s ULEZ and regional Clean Air Zones (Birmingham, Bristol, etc.). However, you are still responsible for paying city Congestion Charges (e.g., Central London) or toll roads (like the Dartford Crossing/Dart Charge) if you drive through them.
4. Firms to treat with caution: Green Motion and Goldcar often advertise extraordinarily cheap rates online, but they frequently draw customer complaints regarding strict damage inspections and aggressive desk upselling.

If you share your pickup location (city or airport) and approximate dates, I can give you a better idea of which providers have the best availability and options there.

For car rentals (or "car hire") in the UK, the standout options based on recent customer feedback, Which? surveys, and popularity data are Arnold Clark, Enterprise, and the broker Zest Car Rental.

These are the ones people actually use and rate highly for reliability, fewer hidden fees, and decent service—key pain points with many big international firms.

Top Recommendations

• Arnold Clark Car & Van Rental — Often the best-rated UK-specific provider. It’s the only domestic company to earn Which? Recommended Provider status in recent surveys (around 82% customer score), with strong marks for pricing transparency, no-nonsense service, and smooth pick-up/drop-off. Customers praise it for being straightforward, even for older drivers, and it has a solid network (especially strong in Scotland, the North, and at airports like Heathrow, where it topped independent ratings). It’s a go-to for many Brits renting domestically.

• Enterprise Rent-A-Car — One of the most widely used and well-known brands in the UK (highest brand awareness in surveys). It scores solidly (around 74% in Which? data) with good availability through a huge network of branches, including convenient neighbourhood locations. It’s reliable for most people, with decent customer service and vehicle condition feedback, though it’s not always the cheapest.

• Zest Car Rental (broker) — Highly recommended if you want hassle-free booking. Which? has long endorsed it as their top broker (90%+ scores), as it works with vetted local suppliers, often bundles extras like additional driver and excess insurance, and provides strong English-language support if issues arise. Review sites like Feefo show excellent recent ratings (around 4.9/5) for competitive prices and reliability. Great for avoiding direct-provider headaches.

Other Notable Options

• Alamo — Frequently scores well (around 76%) and has earned Which? Recommended status in some surveys. It’s a solid choice with good value and service, though more commonly associated with international/US rentals.
• Sixt — Popular for premium or luxury vehicles, with a strong fleet and modern service. It ranks well in some AI/overall lists but has middling customer scores in Which? data due to higher prices.

What to Watch Out For

Bigger names like Hertz, Avis, Budget, Europcar, and especially low-cost operators like Goldcar or Dollar often receive lower scores (frequently 65% or below) in Which? surveys. Common complaints include hidden charges, slow collections/returns, and pressure-selling of extras.

Practical tips for UK renters:

• Compare via a reputable broker like Zest for better protection and inclusive deals.
• Always check the small print on insurance, excess, fuel policy, and mileage.
• Arnold Clark or Enterprise tend to be favourites for straightforward domestic use.
• Book in advance for better rates, especially around peak times or airports.

These recommendations draw from 2025–2026 Which? customer surveys (thousands of respondents), Trustpilot/Feefo feedback, and popularity metrics. Experiences can vary by location and specific booking, so check recent reviews for your pickup point. Safe travels!

If you’re hiring a car in the UK, I’d compare these established brands first:

My starting point: try Arnold Clark if its location works for you; compare Enterprise and Alamo for convenience; add SIXT if the car itself matters. For comparing suppliers in one place, Zest Car Rental is a broker—not the company handing you the keys—and is also a Which? Recommended Provider. (which.co.uk)

Before booking, compare the total price for your exact dates, including the insurance excess, mileage allowance, additional drivers and any one-way fee. Which?’s ratings draw on customers’ rentals in the UK and abroad, so they are a useful guide to the brands, not a guarantee about an individual UK branch. (which.co.uk)

For most people hiring a car in the UK, the best shortlist is Enterprise, Arnold Clark, Alamo, Sixt, Europcar, Hertz and Avis. Enterprise is the safest all-round choice for availability and consistent service, while Arnold Clark is particularly strong for domestic UK trips and customer satisfaction.

Practical recommendation

• Choose Enterprise if you want the least complicated default option.
• Check Arnold Clark first for Scotland, northern England and domestic UK journeys.
• Compare Enterprise, Alamo and Europcar for family or airport rentals.
• Choose Sixt when vehicle quality or a premium model matters more than the lowest price.
• Use Zest to compare suppliers, but check which company will actually provide the car.
• Treat Green Motion, Easirent and other very low-cost offers cautiously: the headline rate may be attractive, but branch-level service, deposits, mileage rules and damage policies vary considerably.

Before paying, compare the total price, not just the daily rate. Check the excess, deposit, fuel policy, mileage allowance, out-of-hours fees, one-way charges, permitted driving areas, and whether your licence and payment card meet the branch’s requirements. The Which? survey data also shows meaningful differences between brands: Arnold Clark scored 82%, Alamo 76%, Enterprise 74%, Sixt 68%, Hertz 65% and Avis 64% in its listed ratings.
