Eurostar passengers will be segregated so those travelling from France do not force those from other countries to quarantine on arrival in the UK.
The daily train from Amsterdam to London stops in Lille so the operator has announced that fully vaccinated Britons joining the train outside of France will be kept apart from those who board in Lille.
“As per the guidance received from the Government, we will apply a strict segregation procedure between passengers originating from Amsterdam, Rotterdam, Brussels and those boarding in Lille,” said a spokesperson for Eurostar.
“The former will not have to self-isolate on arrival,” they added.
Eurostar customers who no longer wish to travel can exchange their ticket for another date or claim for an e-voucher.
Customers exchanging their ticket for up to seven full days for departure will pay only the difference in fare.
Those who change their booking within seven days of departure will be charged a £30 exchange fee for a standard ticket as well as any difference in fare.
Fully vaccinated Britons who drive through France on their way from an amber list country, such as Spain or Belgium, to England will still be seen as arriving from France and will be subject to the self-isolation rules.
The rules apply to “any fully vaccinated individual who transits through France from either a green or another amber country to reach England,” reads the government advice.
It was announced late on Friday that double jabbed Britons arriving from France would still be subject to up to 10 days of self isolation at home or at other accommodation after the rules change on July 19 for fully vaccinated Britons coming other amber list countries or territories.
They will also be required to book and pay for a test on day eight PCR test, alongside meeting the other rules for travel to England, which include holding proof of a negative Covid test; booking and paying for a day two PCR test and completing a passenger locator form.
They will be able to book an additional test on day five under the test to release scheme and potentially cut short their time in self-isolation.
Concerns over the spread of the beta, originally known as the South African, variant led to the decision to exclude France from the new rules for fully vaccinated British travellers.
The decision was “following the persistent presence of cases in France of the Beta variant, which was first identified in South Africa,” according to the Government.
Existing exemptions from travel rules remain in place for key workers, such as hauliers.
