Keys, Clauses and a Walk-Round: Taking a Garage Loan Car Without the Sting

Your car is in for a repair, the service desk has your keys, and someone slides a second set across the counter. The loan car is waiting outside. It feels like a courtesy, and in many ways it is — but the handover is also a small contract. Most courtesy-car disagreements don’t come from dodgy garages or careless drivers. They come from assumptions made in that two-minute exchange: who’s insured, what the excess is, how much fuel goes back in, and whether that scuff on the rear bumper was there before you drove off.
Treat the handover as a mini contract, not a favour. It is far easier to ask a slightly awkward question now than to argue about a bill that lands six weeks after the repair.
Ask for the terms, not just the keys
If the garage has a loan-car agreement, ask to see it. A good one will set out the insurance position, the excess, the fuel policy, any mileage limit and the return time. If it is all verbal, ask for the key points by email before you leave. That is not distrust; it is just a paper trail. In 2026, with many repairs waiting on parts, loan cars are often out for longer than anyone expects. A few clear lines on a sheet can save a lot of fog later.
Who is insured — and for what?
This is the question to nail down first. Garages usually provide cover through their own motor trade policy, but the details matter. Ask whether the cover is comprehensive, whether it includes theft and vandalism, and whether there is a windscreen excess. Check who is allowed to drive. If your partner or a work colleague might need to move the car, ask for them to be named before they touch the keys. Age limits and licence checks are common, and some policies exclude business use.
Don’t assume your own comprehensive policy automatically covers a courtesy car. Many UK policies only include that if you have paid for a courtesy-car extension. If you are unsure, ring your insurer and ask directly: “If I am driving a garage loan car, am I covered?” Get the answer before you drive away, not after.
What does the excess actually mean?
An insurance excess is the amount you may have to pay towards a claim. On a loan car it can be modest, but it can also run into several hundred pounds. Ask three things: how much is the excess, when would it be charged, and is there any way to reduce it? Some garages offer a damage waiver for a daily fee. That is not automatically good value, but it is worth seeing the number rather than guessing.
Also ask whether the garage takes a card pre-authorisation or hold. Not all do, but if they do, you want to know how much is being held and when it is released. A hold is not a charge, but it can affect your available balance for a few days.
Fuel, mileage and the return trip
Fuel policies are usually “full to full” or “same to same”. Photograph the gauge at handover and keep a receipt when you refill. If you are returning the car with more fuel than you started with, mention it — most garages will not refund it, but it avoids confusion.
Mileage limits are easy to miss. A loan car might come with a daily cap, or a total allowance for the repair period, with a per-mile charge beyond that. Ask what happens if the repair takes longer than expected. And confirm the return time and location in writing. If you are dropping the car after hours, ask where to leave the keys and how the fuel level and condition will be recorded.
If you are driving into London, check the congestion charge and ULEZ position. A loan car is not automatically exempt, and a penalty notice forwarded to you weeks later is a miserable souvenir. The same goes for parking tickets and any local clean-air charges.
The walk-round is not rude
Before you move the car, walk around it with your phone. Film all four corners, the roof, the wheels, the glass and the interior. Point out existing scuffs, kerbed alloys and chips, and ask for them to be noted on the handover sheet. Take a photo of the dashboard showing the mileage and fuel level. This takes two minutes and is the single best defence against a damage dispute.
Check the basics too: tyres, lights, wipers, screenwash and warning lights. If a warning light stays on after the engine starts, don’t drive it. Ask for a replacement or for the fault to be looked at. You are responsible for driving safely once you are on the road, but you are not expected to accept a loan car with a known defect.
If the loan car isn’t roadworthy
Don’t drive it. Tell the garage immediately and ask them to record your concern. If the car feels unsafe — a soft tyre, a brake pedal that sinks, a warning light that won’t clear — hand the keys back and ask for another vehicle. If the garage cannot provide one, ask them to confirm that in writing. A calm, factual email is far more useful than a heated conversation at the counter.
Keep the paperwork together
Keep the handover sheet, your photos, any emails and the return receipt in one place. When you return the car, do another quick walk-round and photograph the mileage and fuel gauge. If a bill arrives later for damage, fuel or mileage, ask for a breakdown in writing. Check it against your photos and the original agreement. Mistakes happen, and most garages will correct a genuine error quickly when you have the evidence.
The courtesy car moment is not about being difficult. It is about being clear. Ten minutes of questions and photos at the start is a much better use of your time than a fortnight of emails about a scratch you didn’t cause.
