Step 1: Use a Comparison Site, Not a Rental Company Direct
This is the single most impactful thing you can do. Booking direct with Hertz, Avis or Enterprise typically costs 40–70% more than the same car through a comparison site like VIP Cars. Comparison sites have negotiated bulk rates that are simply not available to the public through direct booking.
Step 2: Book at Least 4 Weeks in Advance
Car hire prices follow the same supply-demand curve as flights. Book early and the price is low. Leave it to the last week and prices can be 2–3x higher for the same car at the same location.
Step 3: Be Flexible on Car Class
The difference between an economy car (VW Polo) and a compact (VW Golf) is often just £10–£20/week — but the difference between a compact and an SUV can be £80–£150/week. Choose the smallest car that genuinely works for your luggage and passenger numbers.
Step 4: Sort Your Own Excess Insurance
Never buy the rental company's CDW upgrade at the counter. Buy standalone excess insurance for £3–£8/day instead. On a week's hire, this saves £70–£120.
Step 5: Choose the Right Fuel Policy
- 'Full to full' — pick up with a full tank, return with a full tank. Best option.
- 'Full to empty' — pre-pay for fuel at booking. Almost never good value.
- Avoid 'same to same' — this means you return with whatever fuel level it had when you collected it, which sounds fine but is open to disputes.
Step 6: Decline Add-Ons at the Counter
- Satnav — use your phone instead
- Baby seat — bring your own if possible (cleaner and you know it fits)
- Additional driver — add partners/spouses for free where possible
- Pre-paid toll pass — usually only worth it in France, Italy and Austria
