The government confirmed last week that summer holidays abroad from England can resume from 17 May at the earliest.

Green countries will require only a privately-paid laboratory PCR test before travel at both ends, with no need for quarantine. However, red countries will require a 10-day quarantine in a designated quarantine hotel and all tests and quarantines will need to be booked and paid for prior to departure. The hotel quarantine cost will be £1,750.
