The Test to Release scheme starts on 15th December. You cannot opt into the scheme before then. If you have arrived into the UK from the 10th of December you can opt in on the PLF to have a test.
The Test to Release for International Travel scheme is for people who need to self-isolate on arrival in England.
Under the scheme you can choose to pay for a private COVID-19 test. If the result is negative, you can stop self-isolating.
The earliest you can take the test is 5 full days after you left a place not on the travel corridor list.
The scheme is voluntary and applies to those self-isolating in England only.
If you do not want to opt into the Test to Release scheme, you will need to self isolate until 10 full days have passed since were last in a place not on the travel corridors list.
