Leaving a car in an unfamiliar compound for two weeks is an act of trust, and it's worth being clear-eyed about it. The overwhelming majority of operators are entirely legitimate, run properly, and will return your car exactly as you left it.
But this is a market with a long tail. The difference between a well-run facility and a poorly fenced field is not always obvious from a listing photograph and a five-star average. This guide explains what the accreditation actually means, what it doesn't cover, and the handful of questions that tell you far more than any review score.
What Park Mark actually is
The Park Mark Safer Parking Award is administered by the British Parking Association on behalf of UK police forces. It's the closest thing this industry has to a recognised standard.
To qualify, a car park is physically assessed by a police-appointed assessor, and must demonstrate:
Appropriate perimeter security and access control — fencing, gates, and a system controlling who gets in
Adequate lighting across the parking area, not just at the entrance
Surveillance — normally CCTV with recording and a sensible retention period
Clean, well-maintained surfaces and clear signage
Management processes for handling incidents when they occur
That's a genuinely meaningful baseline. A facility holding Park Mark has been inspected in person by someone whose job is to assess crime risk. It isn't a self-certification or a paid-for badge.
What Park Mark is not
This is the part that gets glossed over, and it matters.
Park Mark assesses the facility. It does not assess the service. Specifically, it says nothing about:
How your keys are stored, or who has access to them
Whether staff are vetted, or insured to drive your vehicle
Whether your car is driven between locations, and how far
The operator's financial stability
What happens if your car comes back damaged
For park and ride, where you park the car yourself and keep your keys, the facility largely is the service, and Park Mark covers most of what matters.
For meet and greet, it covers perhaps half the picture. Somebody is driving your car. That part sits entirely outside the award.
Use Park Mark as a filter, not a guarantee. It tells you the compound is properly run. It doesn't tell you the operator is.
The four questions that matter most
1. Where exactly will my car be parked?
This is the single most revealing question you can ask, and it takes ten seconds.
A reputable operator names the site — a postcode, an industrial estate, a named compound. They have nothing to hide and every reason to reassure you.
Vagueness here is the clearest warning sign in this industry. "A secure facility near the airport" is not an answer. If that's what you get, book elsewhere — there is more than enough legitimate competition at every UK airport that you never need to accept it.
2. Are your drivers insured to drive my car?
Relevant for any service where staff move your vehicle. They should hold motor trade insurance covering customer cars, and they should be entirely comfortable confirming it.
This matters more than people realise. If an uninsured driver has an accident in your car, the position gets complicated quickly and expensively.
3. Is mileage recorded at handover and return?
Good operators log it both ways as routine. It's a simple, cheap control that deters misuse and settles any question in seconds when you come back.
An operator who doesn't record mileage isn't necessarily doing anything wrong — but one who does has given you something concrete to check.
4. What's the damage procedure?
There should be a documented condition check at handover, increasingly photographic, and a clear claims process. Ask what it is before you need it rather than after.
The three minutes that protect youPhotograph the car from all four corners with the mileage visible before you hand over the keys, and again when you collect it. It takes three minutes and converts any dispute from your word against theirs into a simple side-by-side comparison. Most people skip it. Most people are fine. It still costs you nothing.Sensible precautions before you hand over the keys
Photograph all four corners, with the mileage visible on the dashboard
Remove valuables — and anything with your home address on it. A V5C in the glovebox next to a spare key is a genuinely poor combination while you're demonstrably away for a fortnight
Take your house keys off the ring you're handing over
Note the fuel level
Clear the sat-nav "home" entry if it's set, or at least be aware it's there
Keep the booking confirmation somewhere reachable without wi-fi
None of this assumes bad faith. It's the same logic as photographing a hire car before you drive it away — it protects both parties, and any professional operator will expect it.
Reading reviews properly
Star averages are close to useless on their own. What's worth doing instead:
Read the recent ones. An operator's standards can change quickly, particularly after a sale or a change of management.
Look for specifics. "Great service" tells you nothing. "Car returned with 40 extra miles" tells you a great deal.
Check how complaints are handled. Every operator gets the odd bad review. What matters is whether they respond and resolve, or argue.
Be sceptical of a flawless record. A few hundred reviews with no criticism at all is its own kind of signal.
What actually goes wrong, and how often
Realistically, the common problems are minor: a car returned dustier than it left, a slightly different parking bay than expected, a shuttle that took longer than advertised. Serious incidents are rare, which is why they make the news when they happen.
The most common genuine complaint is unexpected mileage on meet and greet bookings — which is precisely why asking about mileage logging is worth doing, and why photographing the odometer takes ten seconds.
The practical standard
Put together, here's what "safe enough" looks like:
The compound holds Park Mark
The operator names the actual site
Drivers are insured, if it's meet and greet
Mileage is recorded both ways
You've photographed the car at handover
Meet all five and you've covered the realistic risks. It takes about five minutes total, spread across booking and handover.
Every operator listed on Fly Park Compare is vetted for security and reliability — but those three minutes with your phone at the terminal remain the single best protection available to you, and no accreditation replaces them.
For the wider context, our complete guide to UK airport parking covers how the services differ, and meet and greet parking: what actually happens to your car goes deeper on the service where security questions matter most.
What to do when you collect the car
Most of the advice about airport parking security concerns handover. The collection is just as important, and it's when people are most likely to rush.
Before you drive away — and while you're still on the operator's premises — do four things:
Walk round the car. Take the same four photographs you took at handover. Compare them there and then, not at home.
Check the mileage against what you recorded.
Check the fuel level.
Look inside. Glovebox closed, nothing moved, no unexpected wear.
This matters because most operators' terms require damage to be reported before you leave the site. Drive away, and you've weakened your position considerably — however reasonable your complaint might be.
It takes two minutes at the end of a long journey when you badly want to get going. Do it anyway.
What to do if something has gone wrong
If you find damage, or the mileage doesn't add up:
Report it before you leave the site, and get the report acknowledged in writing — an email, a signed form, anything dated.
Photograph everything immediately, including the wider scene, not just the damage.
Ask for the operator's formal complaints procedure rather than relying on a verbal assurance from whoever is on the desk.
Keep your booking confirmation and your handover photographs together.
Most disputes resolve quickly when there's a clear photographic record on both sides. The ones that drag on are almost always the ones where nobody documented anything at the start.
A sense of proportion
It's worth ending on this. Millions of cars are left at UK airport car parks every year, and the overwhelming majority are returned exactly as they were left. The precautions in this article aren't a response to a widespread problem — they're cheap insurance against an uncommon one.
Five minutes of care at booking, three at handover, two at collection. That's the whole investment, and it removes essentially all of the realistic risk.
