Almost three out of four Britons planning a break for August Bank Holiday will stay in the UK, according to research on behalf of the British Vehicle Rental and Leasing Association (BVRLA).
A survey of more than 2,000 adults found 72% of those aiming to go away this weekend would make it a domestic trip.
Young adults are most likely to be holidaying in Britain, according to the study, with 77% of 18-34-year-olds planning a domestic trip and almost one in four (24%) looking to hire a car to do it.
However, Londoners appear even more likely to take a domestic break, with 80% of those intending to travel planning to do so, and 35% set to hire a car.
The study found 33% of London travellers and 27% of 18-34-year-olds intending to take a train.
BVRLA chief executive Gerry Keaney said: “Most people will be staying local, which we suspect is a knock-on effect of the vote to leave the EU and the increasing cost of holidaying abroad.
“Plenty of UK holidaymakers are planning to rent cars, particularly young people and Londoners. We expect the actual numbers to be even greater, as planned train strikes tip the scales in favour of car hire.”
He added: “We advise anyone planning to hire a car to reserve their vehicle in advance.”
Market research firm Opinium surveyed 2,005 UK adults on August 5-9 on behalf of the BVRLA.
