The agency, which was owned by Peter Buckell, also had branches in Great Yarmouth and Wymondham which he acquired from Harvey World Travel in 2009.
An Abta spokeswoman said the agency had been unable to meet its financial commitments.
Holidaymakers are advised to contact the principal, with more information available here.
The agency was a member of Advantage.
