The updated rules were due to be passed into UK law by January 1, but the government has yet to release the full details to the industry.

With the new regulations scheduled to come into force from July 1, Abta has continued to lobby the government to release their exact wording.

Alan Wardle, Abta’s director of public affairs, said: “We are still waiting on the wording of the draft regulations from government – and until we get this, businesses can’t make the necessary changes to prepare for July.

“The window is becoming increasingly tight for them to plan, putting them in a potentially difficult situation. We are continuing to press the government to get things moving.”

The UK regulations have to comply with the requirements of the EU’s Package Travel Directive, which was passed in 2015. The UK’s exit from the EU will not impact the introduction of the new law.

Both the Department for Transport and Department for Business, Energy & Industrial Strategy have held consultations on the new PTRs, including changes to the Atol scheme to ensure it complies with the directive.
