Travel industry bodies have warned of a dive in consumer confidence unless the government works hard on its messaging and guidance around its 14-day quarantine measures.
The new quarantine measures will take effect on 8 June and be reviewed every three weeks.
Arrivals by air, sea or rail will be asked to fill in a form with their contact details, and indicate where they intend to serve their 14-day self-isolation requirement.
The measures will be enforced via spot checks; anyone flouting the rules could face fines of up to £1,000 if they do not comply.
An Abta spokesperson said the measures would “put many people off travelling abroad or visiting the UK, and will therefore have a hugely damaging impact on the UK inbound and outbound tourism industries”.
“It’s therefore critical that the government regularly reviews this policy – including assessing its effectiveness and how it works with other control measures,” the spokesperson said. “We’d also continue to urge the government to keep any measures proportionate, targeted and limited only to what is necessary and to seek a coordinated approach with destinations in the EU and beyond.
“In addition, as we enter the recovery phase it is critically important that both businesses and travellers are given clear and consistent guidance and messaging in relation to travel and tourism. This will be vital to support consumer confidence in future travel plans.”
Julia Lo Bue-Said, chief executive of The Advantage Travel Partnership, said the uncertainty would have “deep consequences”.
She said: "The news shared by the Home Office that travellers arriving in Britain from 8 June are required to self-isolate for 14-days places tremendous strain on tourism businesses.
“The health and safety of travellers and our colleagues is our number one priority and we ask that government reconsider all available options to keep travel moving.
“We urge the government to increase consultation with the travel industry around the concept of air bridges to provide a lifeline to travel agents, airlines, hoteliers, tour operators and business travel.
"The uncertainty that the government has created around when British travellers can travel abroad again is causing deep consequences for the tourism industry.
“Our research shows that two thirds of Brits would like to head overseas once restrictions are lifted, but they will only have the confidence to if the UK government works with the travel sector to establish guidelines that protect travellers."
