Several countries on the list are expected to require Britons to self-isolate on arrival, including high-profile Commonwealth destinations such as Australia and New Zealand, which are thought unlikely to re-open borders before Christmas.
The 24 are: Andorra, Belgium, Croatia, the Czech Republic, Denmark, Faroe Islands, France, Germany, Gibraltar, Greenland, Italy, Liechtenstein, Luxembourg, Monaco, Netherlands, Poland, Réunion, San Marino, Serbia, South Georgia and Sandwich Islands, Spain, Switzerland, Turkey and Vatican City.
Insurers will not cover travellers for any disruptions caused by booking a trip to a destination with any border restrictions. You should check the latest information before booking your trip.
Local lockdowns in Britain could also put an abrupt end to plans if the spread of coronavirus picks back up either in your home region or your destination of choice, as seen with Leicester.
Travellers will have to bear all the risk as they may be unable to claim a refund for a holiday lost to a local lockdown.
How to protect your money
Depending on how you book and who you book with, you may be able to ensure that you will not lose out entirely if the trip is cancelled.
Some travel operators are offering the flexibility to cancel trips with full refunds “no questions asked” up to seven days before departure, including travel firm Audley Travel.
When it comes to booking flights, major airlines including easyJet, Ryanair and British Airways airlines are now selling “flexi-tickets”.
Flexibility, safety and trust will become increasingly important for travellers and may allow travel providers to charge more of a premium.
Each airline has different policies so it’s important when buying these tickets to check that you won’t be out of pocket if your flight is cancelled.
British Airways has introduced a “book with confidence” policy, allowing anyone with a booking due to travel up until August 31 , or any bookings made from March 3 for travel before the end of the year, to qualify for a range of flexible rebooking options, including taking a voucher valid for travel for two years.
Don’t forget that if you make bookings on your credit card and the airline or the hotel cancel on you, you can ask your credit card provider for a refund under Section 75 of the Consumer Credit Act. The section is a legal act that protects you when you spend on your credit card but the value of the ticket must be between £100 and £30,000 to make a claim.
If you booked with a debit card you may be able to make a claim using the Chargeback scheme. This gives people a chance of getting their money back from their bank if a service has not been provided. This will only get you your ticket cost back, and will take time.
