Travellers returning from 33 "red list" countries will have to pay £1,750 to quarantine in hotels for 10 days, Health Secretary Matt Hancock has told MPs.
As part of a new quarantine system due to come into force next week, the government has booked 4,600 rooms across 16 hotels for new arrivals from certain countries.
Mr Hancock warned that anyone who tries to conceal they had been in a country on the "red list" in the 10 days before arriving in England would face a prison sentence of up to 10 years.
He also confirmed that those arriving from all countries would now be required to take a PCR test on days two and eight after their arrival in the country, as part of a 10-day quarantine.
There will be fines of up to £2,000 for those who fail to comply with the new testing requirements, the health secretary told the House of Commons.
