The cars on the Burgas lot that block nothing against your card, and the plain meaning of the three words suppliers use.
Three words, often confused
Suppliers use all three, sometimes in one sentence, and the difference decides how much of your money is unavailable while you are on holiday.
A sum the supplier blocks on your card for the rental and releases afterwards. On the cars filtered above, this is zero.
The most you would pay if the car is damaged. It exists whether or not a deposit is held, and it is what extra insurance reduces.
The block itself, sitting against your available balance. It is not a charge, but the money is unusable until it clears.
What it changes
A blocked deposit is not a charge, but it behaves like one for the length of the rental. On a two week trip that is two weeks of a few hundred euros you cannot spend, which is a real constraint if the same card is paying for the holiday.
No deposit removes the hold. It does not remove the excess, and it does not make the car yours to return in any condition.
If your real worry is the cost of an accident rather than the availability of your balance, the thing to buy is a lower excess, not a different deposit arrangement. The two are solving different problems, and suppliers rarely say so out loud.
Paying with a debit cardBefore you filter
Yes. The card confirms who is driving and covers anything you add later, such as fuel or a toll. What changes is that nothing is blocked against it for the duration of the rental, so the balance stays available to you.
Not meaningfully here. Burgas is a flat market, roughly EUR 16 to EUR 36 a day across the whole window, and the no deposit cars sit inside that same range rather than above it. In cities with an expensive fleet the gap is real; on this coast it is small enough to ignore.
The excess in your agreement applies, exactly as it would with a deposit. No deposit means the money is not held in advance, not that the car comes without responsibility. If that worries you, the honest answer is to reduce the excess with insurance rather than to choose a deposit.
Usually, and that is the main reason people look for them. It is still worth confirming with the supplier before you book, because the rule belongs to the supplier rather than to the country. There is a separate page here on hiring with a debit card.
The list above is already filtered to the cars that hold nothing. Put your dates in and it will show which of them are free for that window, with the total for the whole rental.
