Welcome back to my Car Rental in Ireland series. This is Episode 2, where I’m diving into the fees and hidden costs that can really add up when you rent a car. Some of these are predictable, others may catch you by surprise – but after this installment, you’ll know what to watch for and what you can skip.

It’s easy to get excited about a €126 rental quote… until the final bill comes in at over €300. Here’s how it happens.

Diesel vs petrol
Renting a diesel vehicle often costs more upfront, but depending on your driving, you may save on fuel.

One-way rentals
Some rental companies don't have a one-way fee between airports but returning to or from non-airport locations can add charges.

Taxes
Some companies roll VAT into the quoted price, others add it later. Always check how taxes are applied.

Insurance (SCDW/Excess)
Strongly recommended – but detailed enough that I’ll cover it fully in the next installment.

Cross-border fee
Driving into Northern Ireland usually adds a flat fee per rental.

Additional driver
Adding a second driver will increase your daily cost.

Fuel policy
Most rentals are full-to-full. Prepay fuel is sometimes offered, but usually only at the counter.

Age-related costs
Under 25? Few companies will rent to you. Over 75? Policies differ; some require extra paperwork or fees.
Over 70? You'll find all the info you need here about senior policies – and which companies are the easiest for seniors to rent from.

GPS rental
Skip it. Use your phone’s map app instead. (I think paying for GPS is a waste of money.)

Toll tag device
Usually not worth it – tolls in Ireland are inexpensive, and most travelers pay less than the weekly tag fee. (More info on tolls & prices here.)

Admin fees
Some companies add fees for using your own insurance or certain payment types. Expect an admin fee if you get a traffic, parking, or toll violation.

Airport surcharges
Typically included in car rental quotes, but not always when part of a package deal.

Mileage limits
Most rentals in Ireland are unlimited mileage, but double-check the fine print.

Child seats
Not overly expensive to add on, but supply can be limited.

Out-of-hours pickup/return
Not usually a problem at airports, but at city locations you’ll want to confirm opening hours.

As you can see, fees and extras can add up quickly. Knowing which are necessary, which can be skipped, and which you’ll likely face helps you budget wisely and avoid surprises at the rental desk.

In the next episode, I’ll break down car rental insurance in Ireland – the most confusing part of the entire process – and show you the types of coverage, what they mean, and how to decide what’s best for your trip.
