John Major, a spokesman for the Confederation of Passenger Transport UK, said customers who have already paid for a package holiday will get a full refund.
Customers will be contacted over the next few days with details of how to get their money back, he said.
The firm was a member of the Bonded Coach Holidays Scheme which protects clients' money.
"While appreciating the disappointment and upheaval these situations cause to people looking forward to their holidays, it does highlight the benefits of customers ensuring the package holiday they book is with a company that is the member of the Bonded Holiday Scheme," Mr Major said.
