Stansted parking booked but need to enter earlier

[Kindnesskindnesskindness]

I’ve booked parking for tomorrow but stupidly, it doesn’t allow us enough time (I’d misread our flight time)

Will it allow us to enter slightly earlier ? Is there a grace period?

TIA

Which parking at Stansted and booked through whom? - you really need to check the t's and c's of your purchase. Are you talking about 20mins or 2hrs?

I've never had a problem entering the car park early as I always end up panicking and leaving earlier then I really need to just in case.

Thanks for the posts,
It’s the official short term car park and it will be 30 mins max.

I can only find information regarding over staying but nothing about entering early,

From the FAQ:

"If your booking will change by less than 6 hours (for example if your flight time has changed slightly) there’s no need to contact us to change your booking. You can arrive in the car park up to 6 hours earlier and leave up to 6 hours later without incurring a charge."

I recently needed to know exactly this as our flight time from Stansted has changed and the company we'd booked through said the same as the PP that Stansted has a 6 hour window either side

No idea how I missed that. I could definitely only find reference to going back to the car park late. Or so I thought 🤔

thank you both
