Long Stay or Short Stay at Birmingham? What the Difference Really Is
The names describe how they are priced, not where they are. Picking the wrong one is an expensive mistake.

Airport Guides

Declare the vehicle size when you book. An oversized charge agreed in advance is a few pounds; the same charge discovered at the barrier is dearer and non-negotiable.
This catches out more people than it should, because "large" starts smaller than most drivers assume.
Usually anything over about five metres long or two metres high.
That threshold catches more than vans. A large SUV with a roof box frequently exceeds the height limit, and long-wheelbase estates and seven-seaters often exceed the length.
Limits vary by operator, so the figure in your chosen car park's terms is the one that counts rather than a general rule.
Two metres sounds generous until you add a roof box to an ordinary family car.
Because it is a physical barrier, not a pricing decision.
Multi-storey car parks have height restrictors at the entrance. If you do not fit, there is no negotiation — you cannot enter at all, and you are turning a long vehicle round on a ramp with a queue behind you.
Surface car parks have no such limit, which is why park and ride and off-airport sites are usually the practical answer for anything tall.
A larger bay, or two ordinary ones.
An oversized vehicle occupies space the operator could otherwise have sold twice. The charge is for that rather than a penalty.
Declared in advance it is modest and the bay is reserved. Undeclared, you arrive at a site with no suitable space left — the version that ruins mornings.
Mention it even if the car itself is ordinary.
A roof box adds thirty to fifty centimetres, usually enough to fail a two-metre restrictor. Many travellers fit it the night before and forget it is there. The restrictor will not.
Off-airport park and ride — surface parking, no height limit, cheapest
Long stay — usually surface, check the specific car park
Short stay multi-storey — height restricted, often unsuitable
Meet and greet — confirm first; some operators decline large vehicles
Meet and greet is the one to check rather than assume, because drivers may not be insured for a vehicle above a certain weight or class.
Rarely at standard car parks, and never without asking.
Most sites will not take a motorhome at all, and those that do charge for multiple bays. Specialist long-term storage near the airport is usually the realistic answer.
Ring before booking anything. A refusal at the gate with a motorhome is a considerably bigger problem than with a van.
Towbars are fine; trailers almost never are.
A towbar adds a few centimetres and occasionally affects which bay you are given. A trailer is a separate vehicle for pricing and usually prohibited outright.
If you must leave one, ask about it specifically — do not assume the vehicle booking covers it.
Measure, then read the terms.
Know your height with anything on the roof and your length with anything on the back, then check the chosen car park's stated limits.
Compare the totals including the oversized charge across the Birmingham options, because the cheapest base rate is often not the cheapest once that charge is added.
Usually over about five metres long or two metres high, though limits vary by operator.
Yes. It commonly pushes an ordinary car over a multi-storey height restrictor.
Often not, because of the height restrictor. Surface car parks are the practical option.
Some operators will, some decline. Confirm before booking rather than assuming.
You may be charged more on arrival, or turned away if no suitable bay remains.
No, and that is worth knowing before accepting the first quote.
Some operators charge a flat oversized supplement, some charge for two bays, and a few surface car parks make no distinction at all because space is not tight.
The spread between those three approaches is wider than the usual difference between operators, so a van owner has more to gain from comparing than an ordinary driver does.
Check whether the site accepts liveried or ply-lined vans at all.
Some car parks exclude commercial vehicles entirely, regardless of size, because of insurance or because tools in a van change the risk profile of the site.
If the van is your work vehicle, empty it properly as well as declaring it. Tools left in a van for a fortnight are exactly what the contents exclusion in your policy was written about.
Slightly, because there is only one set of car parks to choose between.
At a multi-terminal airport a van driver has to find a surface car park that also serves the right terminal, which narrows the options twice. At Birmingham the second constraint does not exist.
That makes the search simpler, though it does not make the restrictors any higher — the height limit is still the thing that decides it.
