Renting a Car in Spain: What UK Drivers Need to Know

If you hold a UK photocard driving licence, you can rent a car in Spain without an International Driving Permit (IDP). GOV.UK says you do not need one to drive there, but it also tells you to check with the hire company, because desks sometimes ask for one anyway. Bring your licence, your passport and a credit card in the main driver's name, and the rest of this guide covers where UK drivers actually lose money: excess insurance, fuel policies, deposits and tolls.

Do you need an IDP to rent a car in Spain?

For most UK visitors, no. The GOV.UK IDP guidance lists Spain as a country where you do not need one if you hold a standard UK photocard licence. There are two caveats worth knowing.

• Paper licences and licences issued in Gibraltar, Jersey, Guernsey or the Isle of Man: GOV.UK's general EU guidance says you may need an IDP with these. Check the current wording before you travel.
• The rental desk: Some firms ask for an IDP regardless of the law. Sources disagree on how often this happens, so if you want certainty, read your booking's terms or email the supplier before you fly. An IDP is cheap insurance against an argument at the counter, but you should not need to buy one for a photocard licence.

Not every site you will find online is reliable on this point. One 2026 rental blog we found claimed UK licences always need an IDP; GOV.UK says otherwise. Trust the government page.

What you need at the desk

Requirements vary by company, so treat this as a typical list rather than a rule.

• Licence held for a minimum period: most companies want at least 12 months.
• Minimum age: usually 21, though some require 23 or more. Under-25 surcharges are common.
• Passport as photo ID.
• A credit card in the main driver's name. Debit cards are sometimes accepted but often come with restrictions, and with only a debit card you may be refused the car altogether.

The card matters more than people expect. The company places a hold on it, commonly €1,000 or more, and that reduces your available credit for the whole trip. Use a card with plenty of headroom, not the one you are also using for hotels.

Excess insurance: where the real money is

Every Spanish rental includes basic cover, but it comes with an excess. Guides put the amount you are liable for at roughly €1,000 to €2,000 for damage, and glass, tyres and the underside of the car are often excluded entirely. At the desk, staff will offer "Super CDW" or "full cover" to reduce that to zero. It is the main profit centre of the rental business, which is why the pitch can be persistent.

Your three options

We cannot tell you which is cheapest for your trip, because prices change by season and supplier. What we can say is that if you decline the desk's cover, the company will hold the full excess on your card, so make sure the limit can take it.

Fuel policy: insist on full-to-full

Full-to-full means you collect the car with a full tank and return it full. It is the fairest policy and the one reputable suppliers generally offer. The alternative, often labelled full-to-empty, has you pay the company for a full tank up front at its own price, with no refund for fuel you leave in the tank. That is rarely a good deal.

• Fill up at a station close to the airport or drop-off point, and keep the receipt.
• Photograph the fuel gauge and the mileage at pick-up and at return.
• Check whether the car takes petrol (gasolina) or diesel before you leave the car park. Putting the wrong fuel in is not covered by basic insurance and is an expensive mistake.
• Check for mileage caps on the cheapest deals. Some charge per kilometre over a daily limit, which matters on a road trip.

Inspect the car before you drive off

Walk around the car with the agent and make sure every scratch, scuff and dent is on the check-out form. Take photos or a slow video of all panels, the wheels, the windscreen and the interior, with the date visible. Do the same on return, ideally with a staff member present. If the car is dropped off out of hours, photograph it in the car park and keep the images until the deposit is released.

Spanish law also expects a warning triangle and reflective jacket to be carried. The hire car should have them; check they are in the boot before you leave.

Tolls and the AP roads

Spain has an excellent network of free motorways (autovías, marked A) and a smaller number of tolled ones (autopistas, marked AP). You can usually avoid tolls entirely by taking the A-roads, but the AP is sometimes much quicker.

• Much of the east-coast AP-7 is free, and the stretch south of Tarragona has been toll-free since January 2020.
• The Costa del Sol AP-7 still charges. Published figures for Málaga to Estepona differ between sources, from about €5.70 off-peak to €15.50 in high season in 2026, so check the operator's current tariff before relying on any one number. Tariffs rose by around 3.6 to 4.7% on 1 January 2026.
• Some northern tolls are heavy. One source lists the AP-68 between Bilbao and Zaragoza at €39.90 for a car.
• Payment: cash, card or an electronic transponder (such as Via-T). Rentals rarely include a transponder, so expect to pay at the booth. Carry a card that works for contactless or chip-and-PIN.

Our rule of thumb: let the sat nav show both routes, and take the toll road only when the saved time is worth the money, such as a long inland stretch where the free road is slow. On scenic loops like our Ronda and the White Villages driving loop, you will be on A- and regional roads anyway, and the toll question never arises.

Rules of the road that catch visitors out

These are the standard Spanish limits; check signs, as local limits override them.

• Speed: 120 km/h on motorways, 90 km/h on most conventional roads and 50 km/h in towns, with lower limits on many urban streets.
• Alcohol: the general limit is 0.5 g/l of blood, the same as Scotland and stricter than England and Wales. Treat it as no drinking if you are driving.
• Roundabouts: traffic already on the roundabout has priority, but local habits vary; hang back.
• Parking: blue zones are paid, green zones are typically for residents with limited visitor time, and yellow lines mean no parking. Underground car parks are usually safer and cheaper than fines.

Fines for rental cars are normally passed to the hire company, which then charges your card an admin fee plus the fine. It is better to avoid them than to dispute them months later.

Is a car the right choice for your trip?

For cities, no. Madrid, Seville and Barcelona are cheaper and quicker without a car, and parking is a headache. Our guide to booking Spanish high-speed trains covers the city-to-city legs well. A car makes sense for the places trains do not reach: the white villages of Andalucía, the green north, rural Galicia and the Basque coast. If you are planning a coastal drive, our Galicia road trip and Basque coast drive both rely on a hire car and include driving times and parking notes. For general background on the rental process, our earlier piece on renting a car in Spain is still a useful companion.

A quick checklist before you book

1. Confirm your licence type and read the supplier's terms on IDPs.
2. Book with a credit card in the main driver's name and check your limit.
3. Choose a full-to-full fuel policy.
4. Decide how you will cover the excess before you reach the desk.
5. Photograph the car at pick-up and at return.
6. Check your route for tolls and decide where you will pay them.

What we could not verify

Excess amounts, deposit sizes and toll tariffs vary by supplier, season and year, and the sources we found disagreed in places. Treat every figure above as indicative, and confirm the current numbers with your rental company and the toll operator before you travel.
