When should you book?

One of the main questions people ask when trying to find the best deal on hiring a car is about the best time to book. Is it better to book weeks in advance or last-minute? When do car hire prices drop?

These are all important things to wonder, and the answers may surprise you.

If your road trip dates are set in stone, you can still save money. Knowing the cheapest time to book your car makes a real difference. According to the following data collected by KAYAK, the answer will most likely be to book your car 1 month in advance, or less.

The following graph shows the average daily cost of hiring a car by month of travel. It compares bookings made 1 month, 3 months, and 6+ months in advance.

Key takeaways of our data analysis.

May and November are the cheapest months of the year to hire a car, with an average daily rate of £23. If you want warmer temperatures, I recommend you travel in June (£26/day) or September (£25/day).

Booking 1 month in advance is consistently cheaper than booking 6+ months ahead. It saves £9 per day on average all year, and up to £11 in January.

Best booking window by trip type.

The ideal time to book a hire car depends on what kind of trip you’re planning. Here’s how to approach it based on your situation:

Low-demand travel (off-peak, midweek, smaller cities).

Book 2-4 weeks in advance. Availability is high and prices often drop closer to your travel date. You have flexibility to wait for better deals without much risk.

Peak season holidays (summer, Easter, bank holidays).

Book 2-3 months in advance. Demand spikes during these periods, so waiting too long means higher prices and limited selection. The savings from last-minute booking disappear when everyone’s competing for the same cars.

Airport car hires.

Book 3-4 weeks in advance for the best balance of price and availability. Airport locations see consistent demand, so prices stay relatively stable. Booking too early costs more. Waiting until the last week risks limited availability.

Minivans, SUVs, and luxury cars.

Book 2-3 months in advance. Hire companies keep fewer minivans, SUVs, and luxury cars in their fleets, so these book up faster than standard sedans. If you need a specific vehicle type, don’t gamble on last-minute availability.

Is last-minute cheaper?

Yes, hire car prices generally go down closer to your travel date. There’s a catch, though.

KAYAK data shows the sweet spot is typically 2-4 weeks before your trip, saving £9 per day on average.

However, waiting until the last minute comes with real trade-offs. As you get closer to your travel date, you’re betting that prices will drop faster than availability declines.

During busy periods, that bet often doesn’t pay off. You might find a cheaper daily rate, only to discover the car you wanted is gone.

Bottom line: last-minute booking works best for off-peak travel when availability is high and companies are keen to fill capacity. For peak season, holidays, or when you need a specific vehicle type, the availability risk outweighs the potential savings.

Early vs. last-minute booking: when each makes sense

  • Book last-minute (1-2 weeks in advance): Off-peak travel, flexible on vehicle type, smaller cities, midweek rentals
  • Book 1 month in advance: Standard holidays, airport pick-ups, when you want the best price-to-availability balance
  • Book 2-3 months in advance: Peak season, holidays, popular destinations, when availability matters more than price
  • Book 3+ months in advance: Minivans, SUVs, luxury cars, large groups, must-have dates with no flexibility

Top 3 tips to save when hiring a car

1. Don’t book too early

While it may seem counterintuitive, booking more than 6 months in advance is often the most expensive option. In most months, rates rise the earlier you book, especially for peak travel periods like July and August.

2. Target the shoulder seasons

If you’re flexible with travel dates, consider going in May, October and November. Prices are significantly lower than in peak summer. You still get pleasent weather and fewer crowds.

For example, May 1-month bookings are £23/day, vs. £33/day in July.

3. Choose the same pick-up and drop-off time

Car hire companies typically charge by the day, not by the hour. This means if your drop-off time is later than your pick-up time, you could be charged for an extra full day.

For example, picking up a car at 4 pm on Monday and returning it at 6 pm on Wednesday would count as 3 days, not just 2 and a few hours. To avoid this and save money, try to match your pick-up and drop-off times.

Why prices fluctuate

The first thing to keep in mind is that hire car prices change a lot, and there are a number of factors that determine the price on any given day. Prices can fluctuate because of the season, a particular bank holiday, the car category, the car hire company, and timing (just to name a few).

In general, car hire companies want to hire out as many cars as possible, just like hotels want to fill as many rooms as possible. They’ll price cars competitively to increase demand, but when demand is high, they may raise prices to capitalise on it.

Keep in mind that the base price is the most likely thing to change. All of the additional elements of the car hire, from young driver fees to baby seats to ski racks, will stay the same price regardless of the timing. This background information will help explain how far in advance you should book your hire car.
