The three countries were previously classed as amber by the UK government, which meant only fully vaccinated arrivals could avoid mandatory quarantine.

Now that Germany, Austria and Norway have been promoted to the green list travellers must only take Covid-19 tests before and after entering England, regardless of their vaccination status, and do not have to self-isolate.

They must pre-book Covid tests for day two after arriving and only children aged 4 and under don’t need to take them. Those travellers only need to self-isolate if they test positive after arriving.

The change comes into force on Sunday at 4am and was announced by Britain’s Transport Secretary Grant Shapps on Wednesday night.

Those who arrive in the UK from Germany, Norway or Austria before 4am on Sunday will be subject to the previous rules for amber countries.

We're making some changes to our travel lists🚦

Firstly, we’re removing the quarantine requirement for fully jabbed travellers coming back from #France.

At the same time, we’re adding key destinations ☀️ Germany, Austria, and Norway to the Green List 🟢[1/3]

While it’s right we continue our cautious approach, it’s great news to open more destinations for people wanting to connect with families, friends 👪 and businesses 💼 across the globe 🌍, all thanks to our successful domestic vaccination programme💉[3/3]

The UK government sets the red, amber and green lists for England, while Scotland, Wales and Northern Ireland are in charge of their own lists. They usually adopt the same changes and will likely make an announcement on Thursday.
