On the basis that there is normally someone mooching about UKC who will know the answer to any question - what is a compulsory strike-off? I presume that it's a business that is being deregistered by Companies House for not doing what it is legally obliged to?
The background is that my other half had booked parking at MAN for a few days next week. She decided to see if she could cancel the booking but got no email reply from "Trusted Travel" the airport parking website she had booked through. She had the phone number on the booking for the actual car park so called them, and was told very apologetically that she wasn't the first to call, but as far as they knew (they are separate company) Trusted Travel has gone out of business because it hadn't paid them, so they weren't honouring the bookings.
I found a few similar posts at them on Twitter from other people turning up at airports to find they had no booking. I found the company's listing on Companies House, https://find-and-update.company-information.service.gov.uk/company/09891505... and to my very inexpert eye it look like they might have been in trouble for some years having a number of "first gazette notice for compulsory strike-off", which is cancelled the same day as file "micro company accounts". But never having owned a company in the UK I don't know really how it works.
My missus paid on credit card so I suspect it won't be a problem to get the not too much sum back, so this is just more out of interest than anything else. And for anyone booking airport parking - don't use Trusted Travel UK as it is not going to end well!
