Yes, a 21-year-old can rent a car in Ireland, but it is not a straightforward process and comes with significant restrictions and extra costs. The legal minimum age to rent a car in Ireland is typically 21, but this varies by rental company. Many major companies set their minimum age at 23 or 25 for certain vehicle categories. The primary challenges you'll face are a limited selection of vehicle types (often excluding premium, luxury, or larger cars) and a mandatory Young Driver Surcharge, which is a daily fee added to the rental cost.
This surcharge is applied to drivers under a certain age, usually 25, to offset the higher insurance risk perceived by rental companies. You must also hold a full, valid driver's license from your country of residence for at least one, and sometimes two, years. An International Driving Permit (IDP) is highly recommended if your license is not in English.
The table below outlines the policies of major rental companies in Ireland regarding young drivers. It's crucial to check directly with the company when booking, as policies can change.
| Rental Company | Typical Minimum Age | Young Driver Surcharge (Approx. Daily Fee) | Common Vehicle Restrictions for Under-25s |
|---|---|---|---|
| Hertz | 21 | €25 - €35 | Excludes Premium, Luxury, 4x4, Commercial vehicles |
| Enterprise | 21 | €25 - €30 | Excludes Premium, Luxury, People Carriers |
| Avis | 21 | €25 - €35 | Excludes Premium, Luxury, 4x4, Convertibles |
| Budget | 21 | €25 - €30 | Excludes Premium, Luxury, 4x4, Commercial vehicles |
| Europcar | 23 (21 online) | €30 - €40 | Excludes Premium, Luxury, 4x4, Convertibles |
| Sixt | 21 | €25 - €30 | Excludes Premium, Luxury, 4x4, Convertibles |
To ensure a smooth experience, book well in advance, as fewer cars are available for under-25 drivers. Be prepared to present your driver's license, passport, and a credit card in the main driver's name for the security deposit. Scrutinize the rental agreement for the exact surcharge amount and any other fees before signing.

It's possible, but be ready for a major budget hit. I rented a car at 22, and the "young driver fee" was almost as much as the daily rental rate itself. You're stuck with the most basic economy cars, and they'll require a hefty credit card hold. My advice? Get quotes from every company and read the fine print on their websites about age fees. It’s the only way to avoid a nasty surprise at the counter.

From a logistical standpoint, the answer is conditional. The key factor is your driver's license. You must have held a full license for at least 12-24 months, depending on the agency. An International Driving Permit is strongly advised alongside your original license. The rental process is more stringent for young drivers, involving a thorough check of documents and a larger security deposit placed on your credit card. Always confirm these details directly with the rental company before you travel.
