The Keys Are Free. The Fine Print Isn't: A Driver's Guide to Garage Loan Cars

There is a particular kind of relief when a garage says they will sort you a car while yours is on the ramp. You stop worrying about buses, lifts and awkward favours. Then someone slides a clipboard across the desk, and the relief gets mixed with a quiet sense of unease. In 2026, a 'courtesy car' can mean several different things, and the difference matters more than most drivers expect.

At Grosvenor Garage, we would rather you asked the awkward questions before the repair than discovered the answers after it. So here is the blunt version.

First, work out what you are actually being given

Garages and insurers use three labels loosely: courtesy car, loan car and hire car. They are not interchangeable.

• A courtesy car is often provided through an insurer-approved repair scheme. It is usually free for the duration of the repair, but it is commonly a small hatchback, subject to availability, and not guaranteed for the whole job.
• A loan car is the garage's own vehicle. It may be free for a short period, or it may come with a daily rate, a deposit, a mileage cap and a hefty insurance excess.
• A hire car is a proper rental. You will sign a hire agreement, and the fuel, mileage, damage and cleaning rules are usually stricter.

Ask directly: who owns the car, who insures it, what excess applies, and who pays if the repair takes longer than expected. If the answer is vague, assume the worst and plan accordingly.

Your own insurance may not do what you think

Plenty of comprehensive policies include cover for a courtesy car, but it is not automatic across the board. Some policies provide it only while your car is being repaired by an approved garage. Some exclude it entirely. Third-party, fire and theft cover almost never includes it.

Ring your insurer or check your certificate before you rely on your own policy. If the garage is insuring the loan car, ask what excess you would be liable for and whether it applies to any driver or just named drivers. Do not assume that because you are fully comprehensive on your own car, you are covered in someone else's.

If the repair is an insurance claim, ask whether a courtesy car is part of the claim or a separate arrangement. 'Subject to availability' is not a promise. It means exactly what it says.

The handover is where money is quietly decided

Before you drive away, walk around the car with the person handing over the keys. Use your phone torch. Take a short video of all four corners, the roof, the wheels, the windscreen and the interior. Photograph the fuel gauge and the odometer.

Check the condition report. If existing damage is listed, make sure it matches what you can see. If the form says 'none visible' but there is a scuff on the bumper, point it out and get it noted. A cheerful 'don't worry about that' is not paperwork.

Ask about fuel. Some garages run a same-to-same policy; others want it returned full. Ask about mileage limits, cleaning charges and what happens if you return it with a muddy boot or dog hair on the seats. Ask about congestion charges, ULEZ, parking tickets and tolls. Who pays, and how is it handled?

Check the tyres, lights, wipers and warning lights before you leave. Ask whether breakdown cover is included. Confirm the return time and what happens if you are running late. If the repair overruns, who pays for the loan car after the agreed date? Get that answer in writing, even if it is only an email.

The charges drivers discover too late

The obvious cost is the daily rate, but the sting is often in the details: a fuel shortfall charge, a valet fee, a late-return fee, an administration fee, a young-driver surcharge, or an insurance excess that suddenly applies because the car was damaged while parked. Some agreements also include a card pre-authorisation or deposit, which can tie up funds for days.

Read the agreement before you sign it. If there is a damage waiver, understand that it is not the same as insurance. If you are offered extra cover at the desk, you are allowed to say no — but make sure you understand what you are declining.

If something goes wrong

Report any damage or incident immediately, even if it seems minor. Take photos before the car is moved. Do not agree to a repair without a written estimate. Keep the claim reference and every message. When you return the car, ask for a signed condition report and a final statement of charges. If something feels off, ask for it in writing before you leave the forecourt.

Questions to ask before you book the repair

• Is the car a courtesy car, a loan car or a hire car?
• Who insures it, and what is the excess?
• Is there a deposit or card pre-authorisation?
• What is the fuel policy?
• Is there a mileage limit?
• Are cleaning, late-return or admin charges applied?
• Who pays for congestion charges, ULEZ and parking fines?
• Is breakdown cover included?
• What happens if my repair takes longer than expected?
• What is the return time, and where do I leave the keys?

A loan car is a contract, not a favour. The keys may be free, but the fine print rarely is. Ask now, photograph everything, and you will spend less time arguing about a scuffed alloy and more time getting your own car back on the road.
