Firstly, you might be wondering where to book your car rental service, and there are many hire companies to choose from in Ireland. However, the best way to get a good deal is to book in advance and use a comparison website to save you time and money.

The best comparison websites to use in Ireland for car rental are and, which will ensure you get the best deal for your trip. Nothing hurts more than knowing you could have saved a few quid.

Secondly, it is worth knowing that you will need a credit card to book online, and you must present that same card when you pick the car up.

Many rental agencies have age restrictions. They may ask that you are at least 25 years old and have a valid driver’s license for at least a year. However, if you don’t fit these criteria, there may be alternatives.

You also must make sure that you have the correct rental insurance coverage before driving in Ireland.

Additional charges ‒ ways to save money

Additional charges apply if you are planning to add an additional driver, need extra equipment like child car seats or navigation systems, or if you are planning to drop the car off at a different location.

One of the best ways to save money is to try to pick up and drop off your car at the same location. One great place is at the airport (Dublin Airport, Cork Airport, Shannon Airport, Kerry Airport, or the City Airport or International Airport for Northern Ireland) you arrive at. 

Alternatively, most car rental companies have locations in major city centres. Here, you can pick up and drop off the car at the beginning and end of your trip.

When it comes to crossing the border, you should let your agency know you plan to do this, so they can assure that you are covered. Most Irish car rental companies will be happy to cover you, but it is best to check with the company in advance.

It is important to know that in Northern Ireland, which is part of the UK, the speed limits will be marked in miles per hour as opposed to kilometres per hour in the Republic of Ireland. So, take note when the change happens, so you can avoid any speeding fines.

There are options to take either toll roads (M or A roads) or non-toll roads (N or R roads), so it is best to specify this in your GPS before the trip begins and reset it back to normal when you are planning to take a toll road and arrive to a place faster.

So, there you have it. It is as easy as ever to rent a car in Ireland, so make sure you do the research, get a good deal and have an adventure of a lifetime.
