Is Your Car Safe? Birmingham Airport Parking Security Explained
Park Mark accreditation tells you more than any star rating. Here is what it covers and what it does not.

Safety

Take anything valuable, anything with your address on it, and anything you would miss. Leave the car looking empty, because a visibly empty car is the cheapest security measure available.
This is less about trusting the car park and more about how insurance works. Most policies limit cover for items left in a vehicle sharply, and that limit applies regardless of how secure the site is.
Personal belongings cover in a motor policy is typically capped at a low figure, often a couple of hundred pounds. Some policies exclude them entirely.
That cap does not rise because the car park is accredited. It is a feature of your policy, not of the site. A laptop left in a boot for two weeks is almost certainly above the limit.
Travel insurance usually will not help either, since most policies exclude items left unattended in a vehicle.
The question is not whether the car park is secure. It is what your policy pays if the worst happens, and the answer is usually very little.
Electronics — laptops, tablets, cameras, anything with a screen
Documents with your address — the V5C, insurance certificate, post
Spare keys — house keys plus a document showing your address is a serious combination
Sat nav and dash cam — or at least the mount, since a visible mount suggests a device nearby
Anything sentimental — the insurance limit is irrelevant for things you cannot replace
Anything of low value that is genuinely useful on your return.
An ice scraper and de-icer in winter, a bottle of water, a phone cable and a cheap coat all earn their place on a fortnight away. None of them attract attention and all of them help at the end of a long journey.
Child seats are the awkward case. They are bulky to carry and expensive to replace, but leaving them is normally the practical choice — just put them out of sight.
Yes, and it is worth taking more seriously.
With meet and greet a driver takes the car, so the glovebox and boot are accessible to someone for the whole trip.
Reputable operators have no issues at all, and most record vehicle condition on handover. But there is no reason to leave anything valuable in a car somebody else is driving, and the insurance limits still apply.
The same goes for valet parking. For a park and ride site where you keep your own keys, the bar is a little lower.
At least of documents.
The registration document and anything showing your home address is the item most worth removing, and the one most often forgotten. An empty-looking interior also reduces the chance of anyone looking twice.
Leave the glovebox shut but empty rather than open. An open empty glovebox signals that someone has already been through it.
Out of sight is better than nothing, but not as good as out of the car.
A boot is not a safe, and on many cars it is accessible from the cabin. If something has to stay, put it there before you arrive rather than in the car park — transferring bags into a boot in full view of the site defeats the point entirely.
For the vehicle, within limits. For contents, almost never.
Standard terms at Birmingham operators exclude liability for items left in the car. That is normal across the industry rather than a sign of a poor operator.
What a good operator does offer is Park Mark accreditation, lighting, fencing and surveillance — which reduce the chance of the problem rather than paying for it. The secure parking page sets out what accreditation covers.
Take — electronics, documents, spare keys, sat nav, anything irreplaceable
Leave — scraper, de-icer, cable, cheap coat, child seats out of sight
Clear it fully for meet and greet or valet bookings
Load the boot before you arrive, not in the car park
Assume contents are not covered — by the car park or your policy
Low-value items, generally yes. Anything valuable should come with you.
Usually only to a low limit, and some policies exclude them entirely.
Usually yes, for practicality. Put them out of sight where possible.
Better not to. A driver has access to the vehicle for the whole trip.
Yes. It shows your home address and is the single most worthwhile document to remove.
Only in that weather joins the list.
Over a weekend the question is purely about theft and insurance limits. Over three weeks in winter, frost, salt and sap do real cosmetic work on a car, which is when covered parking starts to earn its price.
Scale the spending to the duration rather than to the value of the car, and clear the interior either way.
