The company, based in Sandhurst, ceased being an Atol holder on 13 June. It held the brands Your Holidays, Great Little Escapes, Tunisia First and websites themaldives.co.uk, yourholidays.co.uk, thecaribbean.com and greatlittleescapes.co.uk.
It is a wholly separate company and brand to Great Little Breaks.
The CAA said: “If you are a travel agent of Great Little Escapes and you are currently holding consumer payments which you have not yet paid to Great Little Escapes, you must not use these funds to refund consumers until you have received instructions from the Air Travel Trust.”
It added: “Travel agents will be individually contacted by the CAA with specific instructions for these bookings.”
The authority also told agents not to submit fresh claims while waiting for more information “as these will be rejected”.
Great Little Escapes specialises in city breaks, while Your Holidays has a diverse portfolio, ranging from hen and stag parties, LGBT holidays and packages for bridge players.
Its latest financials show the company lost nearly £77,000 last year and recorded a deficit of £186,000 in 2023.
Details of its latest Atol were unavailable from the CAA on Monday. The Great Little Escapes website currently redirects to yourholidays.co.uk.
The website carries the Advantage Travel Partnership logo. A spokesperson for Advantage said: “We are hugely saddened to see Great Little Escapes cease trading as an Atol holder, having become a member of Advantage in March 2022. Our thoughts are with the team based in Berkshire and their customers, who may have been impacted.”
The group’s Facebook page has been inactive since October 2023, while activity has paused on several of its other social media pages.
Its Your Holidays brand was continuing to post almost daily to Facebook until Wednesday (11 June).
