What you need to rent a car in London

To rent a car in London, you must be at least 21 years old (some companies require 25), hold a valid driving licence, and have a credit card in your name. Your driving licence must be current and, if it was issued outside the UK, you may need an International Driving Permit (IDP) depending on which country issued it. Most rental companies will also ask for proof of address — a recent utility bill or bank statement — and your passport or national ID.

The rental company will place a hold on your credit card, usually between £100 and £500, which is released when you return the car undamaged. This is separate from the rental cost itself. You cannot rent using a debit card at most major companies, though a few smaller operators may accept one if you provide additional documentation.

If you are under 25, expect to pay a young driver surcharge — typically £15 to £25 per day. Some companies will not rent to drivers under 23 at all. Check the specific company's age policy before booking.

Key Takeaways

  • You need a valid driving licence (UK or international), a credit card in your name, and proof of address; most companies require you to be at least 21, though 25 is common for better rates.
  • London has rental desks at Heathrow, Gatwick, Stansted, and Luton airports, as well as city-centre locations on Tottenham Court Road and near Victoria Station.
  • Petrol cars are cheaper to rent than diesel, but fuel costs and London's congestion charge (£15 per day for most vehicles) will add significantly to your total expense.
  • Collision damage waiver (CDW) and third-party liability cover are not always included; check what your rental agreement covers before you drive away.
  • Return the car with a full tank and no damage, and photograph the condition at pickup and return to protect yourself against unexpected charges.

Where to pick up and drop off a rental car in London

The largest rental companies operate desks at all four major London airports: Heathrow (the busiest), Gatwick, Stansted, and Luton. Heathrow and Gatwick have the most choice and longest opening hours. If you are flying in, picking up at the airport is straightforward, though airport rental rates are typically 10 to 15 percent higher than city-centre locations.

City-centre pickup points exist on Tottenham Court Road (central London, near the British Museum), near Victoria Station, and in Croydon. These are cheaper than airport desks and useful if you are already in London or arriving by train. Some companies also offer one-way rentals — picking up at the airport and dropping off in the city centre, or vice versa — though this usually costs more than a standard rental.

Opening hours vary: airport desks typically open from 5 a.m. to midnight, while city-centre locations usually operate 8 a.m. to 6 p.m. weekdays and shorter hours on weekends. Check the specific location's hours before you book, especially if you are arriving outside standard business hours.

Understanding the congestion charge and other London driving costs

London's congestion charge is a daily fee of £15 (or £17.50 if paid after 10 p.m. the same day) for driving in central London between 7 a.m. and 10 p.m., Monday to Friday. The charge zone covers most of central London but not all of it — check the Transport for London website to see if your route is affected. Many rental companies will charge you for this automatically if you drive in the zone, then add it to your final bill.

Some rental agreements include congestion charge coverage; others do not. Read your contract carefully. If the company does not cover it and you drive in the zone, you are liable for the fee, and the rental company may add an administration charge on top.

Fuel is your second major cost. Petrol is cheaper than diesel in London, and most rental cars run on petrol. You will pay roughly £1.30 to £1.50 per litre. Return the car with a full tank; if you do not, the company will refill it at a premium rate (often £1.80 to £2.00 per litre) and charge you the difference plus a service fee.

Parking in central London is expensive and difficult. On-street parking costs £2.50 to £5.00 per hour depending on the zone, and many streets have restrictions. Hotel car parks and private car parks charge £20 to £40 per day. Factor this into your budget if you plan to stay in the city centre.

Insurance and damage cover when renting a car

Rental companies offer collision damage waiver (CDW), which covers damage to the rental car if you have an accident. CDW is not always included in the base rental price — check your quote carefully. If you decline CDW, you are personally liable for any damage, which can cost thousands of pounds.

Your personal car insurance or credit card may cover rental car damage, but only if you check first. Some credit cards offer rental car cover automatically; others do not. Call your insurer or credit card company before you rent to confirm what is covered. If your policy does cover it, you can usually decline the rental company's CDW and save money.

Third-party liability cover (covering damage you cause to other vehicles or property) is legally required in the UK. Most rental agreements include it, but confirm this in writing before you sign. If it is not included, you must purchase it or you cannot legally drive the car.

Excess (the amount you pay toward damage) typically ranges from £500 to £1,500 depending on the company and car type. You can usually reduce this by paying an extra daily fee, often £5 to £15 per day. Windscreen and tyre damage are sometimes excluded from CDW — read the fine print.

Booking a rental car and comparing prices

Major rental companies operating in London include Hertz, Avis, Enterprise, Budget, Europcar, and Sixt. Smaller local companies also operate but have fewer locations. Comparison websites such as Rentalcars.com, Kayak, and Costco Travel (if you are a member) let you search multiple companies at once, though you will complete the booking on the company's own website.

Prices vary significantly by date, time of year, and how far in advance you book. Booking 2 to 4 weeks ahead usually offers better rates than booking a few days before. Weekday rentals are often cheaper than weekends. If you have flexibility, check prices for different dates and times to find the best deal.

When comparing quotes, check what is included: fuel policy (do you return it full or empty?), insurance, congestion charge, airport fees, and any young driver surcharges. A quote that looks cheap may become expensive once these are added. Always read the terms and conditions, especially the cancellation policy — some bookings are non-refundable.

What to do when you pick up the rental car

Arrive at least 15 minutes early. Bring your driving licence, passport, credit card, and proof of address. The rental agent will ask you to sign a contract and inspect the car with you. This inspection is critical: walk around the car and note any existing damage — scratches, dents, missing wing mirrors, broken lights — on the damage report before you drive away. Take photographs or video of the car's condition from multiple angles and keep these on your phone.

Check that the fuel gauge reads full (or whatever level the contract states), test the lights and wipers, and confirm the spare tyre and jack are in the boot. Ask where the nearest petrol station is and whether the car has a satellite navigation system or if you need to use your own phone.

Do not sign anything you do not understand. If the agent tries to pressure you into additional insurance or services you did not book, ask for time to read the paperwork. You have the right to decline add-ons that are not part of your original booking.

Returning the rental car and avoiding extra charges

Return the car on time and with a full tank of fuel. Late returns are charged at a daily rate, sometimes higher than the original rental rate. If you are delayed, call the rental company as soon as possible — some will grant a grace period, though this is not may provide.

Refuel the car at a petrol station before returning it. Do not rely on the rental company's fuel service; it is always more expensive. Keep your fuel receipt as proof you filled the tank. Return the car to the same location you picked it up unless you booked a one-way rental.

Inspect the car one final time before handing over the keys. Take photographs of the odometer reading and the car's condition. The agent will inspect it again and compare it to the damage report from pickup. If new damage is found, you will be charged. If you dispute a charge, having photographs and the original damage report protects you.

Ask for a receipt confirming the car was returned in good condition and on time. Keep this receipt and all paperwork for at least 30 days in case the rental company later claims damage or charges you for something unexpected.

Frequently Asked Questions

Do I need an International Driving Permit if I have a non-UK licence?

It depends on which country issued your licence. If it is from the EU, Iceland, Liechtenstein, Norway, or Switzerland, you do not need an IDP. If it is from outside these countries, you should carry an IDP alongside your original licence. Check with your rental company before booking, as requirements vary.

Can I drive outside London with a rental car?

Yes, most rental agreements allow you to drive anywhere in the UK. Some companies restrict driving to Scotland or Northern Ireland — check your contract. If you plan to drive to Europe (France, for example), tell the rental company in advance; you will need additional insurance and documentation, and some companies do not permit it.

What happens if I get a parking ticket or speeding fine while renting?

The rental company will be notified and will pass the fine to you. You are responsible for paying it. Some companies charge an administration fee on top of the fine itself. If you believe the fine is incorrect, you can contest it directly with the local authority, not the rental company.

Is it cheaper to rent a car or use taxis and public transport in London?

For a single day, public transport (the Tube, buses, and trains) is usually cheaper and faster in central London. A daily Travelcard costs around £15 to £20. Taxis are expensive — a journey across central London costs £15 to £30. Renting a car makes sense if you are staying several days, visiting areas outside central London, or need flexibility that public transport does not offer.

What if the rental car breaks down while I am driving?

Call the rental company when ready — their number will be on your contract and in the car. They will arrange recovery and a replacement vehicle or alternative transport. You are not responsible for the breakdown cost. If you break down outside London, the company will still help; recovery may take longer in remote areas.
