It is almost always necessary to have a credit card to rent a car in Ireland; if you plan to use a debit card, be prepared to have a large cash deposit on hand. It is also important to have comprehensive car-excess insurance, available either through the rental agency itself or through another reputable company such as a credit card provider.
There are many recommended self-driving routes for touring Ireland with a rental car, including a route once named the world’s "Best Self-Drive Holiday Destination": the 2,500 km (1,550 mi) Wild Atlantic Way. Other popular destinations accessible by rental car include the coastal town of Galway, the Cliffs of Moher, Boyne Valley, and the cliff-top "Sky Road".
Children under 5 ft (59 in) in height and weighing less than 36 kg (79 lbs.)—usually those younger than 11 or 12 years—are required to be seated in an appropriate child seat or booster seat. Most rental companies like Europcar and Sixt offer baby or child seats, which must be booked in advance and will cost an additional fee, starting from about €6 ($6.80) per day. Note that some agencies do not provide seats for babies under 6 months old.
Anyone planning to rent a car in Ireland and travel into Northern Ireland or take a car ferry to the rest of the UK will first need to check with their rental provider. The vast majority of agencies do allow rental cars to be driven into Northern Ireland or even dropped off there; however, they will usually charge an additional fee, e.g., 34 € ($38) for cross-border travel with Europcar. But only a few providers like Easirent allow for trips to Scotland, Wales or England.

Expect to pay around 1.30 € ($1.47) per liter of diesel and 1.45 € ($1.64) per liter of petrol.
