This calculator helps estimate the total vehicle rental cost, including daily hire charges and any additional mileage fees.
The base rental cost is calculated by multiplying the daily rental rate by the number of rental days selected.
Most rentals include a set number of free miles per day. Driving within this allowance will not incur additional mileage charges.
If your total mileage exceeds the included allowance, extra miles are charged at the specified per-mile rate.
The calculator combines the base rental amount and any excess mileage charges to provide an estimated total rental cost.
Estimate your expected mileage as accurately as possible to avoid unexpected excess mileage fees when returning the vehicle.
UK rental pricing combines daily hire rates and mileage-based charges.
Most reputable UK calculators show an "all-in" price including VAT (20%), basic third-party insurance, and mandatory local taxes. However, you should explicitly state if optional fees (like child seats) or location surcharges (like airport fees) are missing from the initial estimate.
Security Deposit: Expect a hold on your credit card of £200 to £500 for standard cars, rising to £1,000+ for premium models.
Insurance Excess: Even with standard insurance, you are usually liable for the first £500 to £2,000 of damage. You can reduce this by buying "excess protection" at the desk or from a cheaper third-party insurer.
Yes. Drivers aged 21–24 almost always pay a "Young Driver Surcharge," typically between £30 and £50 per day. Some firms cap this at 10 days per rental. Drivers over 75 may face similar "Senior Driver" fees or be restricted from certain car classes.
While most major UK rentals offer unlimited mileage for short trips, some (especially for luxury or electric cars) may cap you at 90–300 miles per day. Excess miles are typically charged at £0.20 to £1.10 per mile.
Adding another driver usually costs £10 to £15 per day. This covers the insurance risk of a second person behind the wheel.
The standard is "Full-to-Full": you pick up the car full and must return it full. If you don't, the rental company will charge you a significantly higher refuelling rate plus an admin fee.
Sometimes. So ask ahead of booking. Picking up from a "Premium Location" like Heathrow or Gatwick often adds a fee (sometimes called a "Location Service Charge") that can be £30–£40 or a percentage of the total rental.
Child Seats: Approx. £10–£15 per day, often capped at a maximum per rental.
GPS/Sat Nav: Often £15+ per day, though many modern cars now have this built-in or via Apple CarPlay/Android Auto for free.
If you drop the car at a different city from where you started, a "One-Way Fee" will apply. This ranges from £50 to £200+ depending on the distance between the branches.
Absolutely. Booking 3 to 6 months in advance is significantly cheaper than a last-minute booking. Prices are dynamic and rise as "fleet availability" drops, especially during UK summer holidays
In the UK, most major rental companies (like Hertz or Avis) require a credit card in the lead driver's name to hold the security deposit. While some are starting to accept debit cards, they often require you to buy their most expensive "premium insurance" (Zero Excess) to waive the need for a large deposit hold. If you only have a debit card, expect a higher upfront cost or a more rigorous credit check at the counter.
