Rentalcars.com Discount Codes - December 2025

Whether you’re escaping on a family adventure or just need a set of wheels to get you from A to B, getting a great deal on your car hire is easy at Rentalcars.com. As well as the best deals from the biggest operators, these extra tips can help you cut costs even further, so you can get on the road for less.

No hidden fees

Don’t worry about paying extra when you book via credit card – there are no hidden credit card fees. And if you want to make changes to your booking, you won’t come up against any amendment fees, either. And better yet, most rentals include local taxes, collision damage waiver, theft protection, airport surcharges, and road fees in the price. Stay fee-free when planning your dream getaway, and get road-ready without having to pay out for extra cover on add-ons.

You won’t lose out when plans change

Don’t worry about losing money if your plans suddenly change. A lot of deals come with free cancellation, meaning that if you have to rearrange your plans or cut your trip short, you won’t have to pay extra.
