Tenerife car hire: excess, deposit, and what gets added at the desk

The short answer: the excess is your share of the damage, the deposit is only a hold on your credit card — and “CDW included” does not mean “no excess”. The one question you need to ask about any quote, then, is not “is it insured” but “what is the excess, and what does it take to reduce it to zero?”. The card usually has to be a credit card in the main driver’s name. If your holiday is a volcano, a boat trip and a beach anyway, the most honest answer is often not to hire at all — then the Mount Teide Tour with Cable Car Ticket and Transfer for €92 per person covers the one day most people wanted a car for in the first place.

This is the article where a wrong number costs you real money, so it is worth saying at the top what it does and does not do.

It explains the mechanics — what each charge is, why it exists, and where it is written down. It does not print a deposit figure, an excess figure or an insurance price, because those are set per supplier, per car class and per date, and a plausible-looking number from someone else’s blog is exactly how people end up surprised at the counter. Every figure that matters to you is on your own rental agreement and in the supplier’s terms before you book. Read those; this page tells you what you are reading.

The two words that decide everything

Excess is the amount you pay yourself if the car is damaged. Not the total damage — your share of it. If the excess is set at a certain amount and the repair costs more, the supplier covers the rest; if the repair costs less, you pay the repair. It is the number that decides how bad a bad day gets.

CDW — collision damage waiver — is the cover that puts a ceiling on that share in the first place. This is the one people mistranslate into their own language as “fully comprehensive”, and it is not the same thing. A basic CDW is included in most Spanish rentals by law and custom, but “included CDW” and “no excess” are different statements. A car can have CDW included and still leave you liable up to a substantial excess.

So the single question to ask about any quote is not “is it insured” — it will be — but “what is the excess, and what does it take to reduce it to zero?” Everything else at the counter follows from the answer.

What the deposit is, and why the card matters

The deposit is not a payment. It is an authorisation hold: the supplier blocks an amount on a credit card so that the money is unavailable to you but not yet taken from you. If you return the car undamaged and fuelled as agreed, the block is released. Releases are not instant — banks take their own time, and that lag is the source of most “they charged me twice” complaints.

Two practical consequences on Tenerife, both worth settling before you fly:

The card usually has to be a credit card in the main driver’s name. A debit card, a family member’s card or a card in a different name is where bookings fail at the counter, and the desk is not the place to discover it. Check the supplier’s terms for your booking — some Canarian companies do work differently, including options with no card deposit at all, but that is a property of the supplier you chose, not a rule of the island.

The size of the hold tracks the size of the excess. A rental with a high excess blocks more; a rental where you have bought the excess down to zero blocks less, sometimes nothing. If your card limit is modest, this is the deciding factor — and it is a better reason to reduce the excess than fear is.

Compare suppliers and their terms for Tenerife

What appears at the desk after you have paid

Nothing on this list is a scam. All of it is legitimate, all of it is in the terms, and all of it is easier to decline calmly if you knew it was coming.

Excess reduction or “super cover”. The counter will offer to reduce your excess to zero for a daily fee. Whether that is good value depends entirely on what you already hold: cover bought through the booking site, a policy that came with your credit card, or standalone annual excess insurance. Any of those can make the desk offer redundant. What they do not always do is prevent the hold — third-party excess cover usually reimburses you afterwards rather than stopping the supplier from charging you first. If avoiding the hold on your card is the point, buy the supplier’s product; if the cost is the point, the outside cover is usually cheaper.

The fuel policy. Full-to-full is the one to look for: you get a full tank, you return a full tank, you pay for nothing but what you burn. Full-to-empty or similar prepaid arrangements mean you buy a tank at the supplier’s price and hand back whatever you did not use. Keep the receipt from the last fill; a station near the airport and a photo of the gauge at handover have settled more disputes than any argument at the desk.

Additional drivers. Usually a per-day charge, and the reason matters: a driver not on the agreement is not insured. Sharing the mountain roads between two people is sensible; doing it informally is the one shortcut on this page that can void your cover entirely.

Young driver surcharge and age limits. Suppliers set their own minimum age, their own surcharge for drivers under a certain age, and in some cases an upper age limit too. These vary enough between companies that it is worth filtering for them before comparing prices, not after.

Cross-island travel. If you plan to take the car on a ferry to La Gomera, ask first. Some agreements permit it, some require notice, some prohibit it. Turning up at Los Cristianos with a car that is not allowed on the boat is an expensive morning.

One thing that is genuinely different about the Canaries

Prices here carry IGIC, the Canary Islands’ own indirect tax, instead of mainland Spanish VAT. The general IGIC rate is 7 % against a general VAT rate of 21 % on the peninsula.

That is not a discount someone is giving you, and it is not a reason to assume the total will be low — but it does mean that comparing a Tenerife quote against a Málaga or Alicante quote is comparing two different tax regimes. If the island price looks better than you expected, part of the reason is structural. What your own invoice carries is on your own invoice; ask for it itemised if it is not.

The five minutes at handover that decide the argument

Do this every time, and none of the above is likely to matter.

Photograph the car before you drive it — all four corners, the roof, the windscreen, the wheels, and the inside if it is not clean. Photograph the fuel gauge and the odometer. Make sure every mark you can see is on the damage sheet before you sign, including the ones the agent waves off as too small to note. At return, photograph the same things again, and if the office is closed and you are dropping keys in a box, photograph where the car is parked.

Under-wheel damage, windscreen chips and tyres are the three exclusions most often written into the agreement separately from the main cover, and they are also the three most likely on a road that climbs to 2,000 metres. If you take only one thing from this page: check what your agreement says about tyres and glass specifically, because “fully covered” in conversation and “fully covered” in the document are not always the same sentence.

When the answer is to not hire at all

If your plan is one trip to the volcano, a boat trip and a beach week, the tours that include hotel pickup hand you all of the above: no deposit, no excess, no damage sheet. The question of whether you need a car at all is worth settling first — I have gone through it honestly in do you need a car on Tenerife, including the days where the answer is no.

And if you do hire, the drive that actually justifies it is the one to plan the days around.

Our recommendation

For most people who hire: decide on the excess before you compare prices, not after. Filter for suppliers that accept a credit card in your name, buy cover wherever it is cheapest, and expect a hold that matches the size of the excess. The five minutes of photos at handover are the cheapest part of the whole process.

For anyone who only wants a mountain day: do not hire at all. The Mount Teide Tour with Cable Car Ticket and Transfer costs €92 per person, takes seven hours, picks you up in the south and includes the cable car booking — against two days of hire plus fuel, parking and a deposit, that is the simpler sum for a couple.

For anyone a rental car still makes sense for: staying in the north, heading to Anaga, or staying longer than ten days. For this group, the effort in this article pays off — and with a family of four the sums tip anyway, because every transfer is charged four times and the car only once.

For anyone the Teide tour is not for: anyone who has already been up, anyone who needs the summit permit for the crater rim — which is not included — or anyone travelling with a toddler for whom seven hours with a change in altitude is too much.
