Hidden charges are the single biggest complaint about car hire in Spain. You book a price online, arrive at the desk, and find yourself facing costs you were not expecting — sometimes running to hundreds of euros. Some of these are genuinely avoidable. Others are legitimate charges that apply regardless of where you book. Here is an honest guide to both.
The most common and most costly surprise in Spanish car hire is the security deposit. On a standard rate — the kind sold by most price comparison sites — the hire price includes only basic insurance, leaving an excess of 1000€ to 2000€ as your personal liability. The supplier blocks that amount on your card at collection to secure it.
This is not technically a charge — if the car comes back undamaged, the deposit is released. But for the duration of your holiday, that money is unavailable on your card. And if the agent offers to sell you counter insurance to reduce or eliminate the deposit, that cost can add 150€ - 250€ or more to a two-week hire.
The way to avoid this entirely is to book a zero excess, all-inclusive rate. When full cover is included in the hire price, no deposit is held. All zero excess rates on spain‑car‑rental.com work this way — the price you see includes everything, and nothing is demanded at the desk beyond a fuel deposit (see below).
All suppliers available through spain‑car‑rental.com operate on a full-to-full fuel policy: you collect the car with a full tank and return it full. This is the fairest and most transparent policy — you only pay for the fuel you actually use.
A small fuel deposit — typically 100€ - 150€ — is held on your card at collection and released when the car is returned with a full tank. This is a standard industry practice and applies across our supplier panel. It is not a hidden charge, but it is worth being aware of in advance.
Goldcar also offer a full-to-empty option (sometimes called an 'full- as is' policy), where you pay for a full tank upfront and return the car without refilling. A proportional refund is given for any fuel remaining in the tank on return — however, a fuel service charge of around 20€ - 25€ applies with this policy. Full-to-full remains the more transparent option for most renters.
If more than one person plans to drive the car, an additional driver must be added to the hire agreement at the desk. Most suppliers charge a daily fee for this. It is a legitimate cost but one that catches people out if they have not budgeted for it.
Two suppliers on our panel — Drivalia and Solcar — include one additional driver at no extra charge on their zero excess rates. If you know you will need a second driver, choosing one of these suppliers removes that cost entirely.
Sat-nav units, child seats, baby seats and booster seats are typically charged as extras on top of the hire rate. GPS in particular can add a significant daily cost — most travellers find a phone mount and a free navigation app a far cheaper alternative. Child and baby seats, where legally required, must be booked in advance as availability is limited, especially in peak season.
Some suppliers offer an optional breakdown cover upgrade, available even on top of a zero excess rate. Standard hire agreements include basic roadside assistance for mechanical failure, but an upgrade typically adds more comprehensive cover — including assistance for incidents such as a flat tyre, lost keys or running out of fuel. If you are planning long drives, travelling in remote areas, or simply want complete peace of mind, it is worth considering at the time of booking.
Drivers under 25 are subject to a young driver surcharge, charged per day for the duration of the hire. The surcharge varies by supplier and vehicle category. This is a fixed cost imposed by the suppliers and cannot be waived — but it is clearly disclosed at the time of booking on spain‑car‑rental.com, so it is never a surprise at the desk.
Some suppliers charge a fee for collecting the car outside of their standard operating hours — typically late at night or very early in the morning. If your flight arrives at an unusual time, check the supplier's desk hours before booking and factor in any out-of-hours charge. This will be disclosed in the booking terms.
Collecting and returning the car at different locations (a one-way hire) attracts a drop charge that can range from modest to substantial depending on the distance and the supplier. Driving across borders — into Portugal or France, for example — also carries a cross-border charge and requires advance permission from the supplier. Neither of these is a hidden charge as such, but both are easily overlooked at the time of booking.
Returning the car in an unreasonably dirty condition can result in a cleaning charge. This is at the supplier's discretion, but a car returned with mud, food debris or staining inside is likely to attract a fee. Returning the car in broadly the same condition you received it is the simplest way to avoid any dispute.
To be clear about what booking through spain‑car‑rental.com gives you: every rate includes zero excess insurance, debit card acceptance, and pay-on-arrival booking with no upfront payment. The price you confirm at the time of booking is the price you pay at the desk — there is no insurance upsell, no deposit beyond the fuel hold, and no last-minute additions for the cover itself.
Additional drivers, child seats, GPS and similar extras are charged separately where applicable — but these are disclosed clearly at the booking stage, not sprung on you at the desk. Young driver surcharges and one-way fees are similarly shown upfront. The aim is that nothing in your final bill should come as a surprise.
