If you are booked into regulated tourist accommodation in the Canaries, you will be obliged to:
present an official, negative COVID-19 test taken no more than 72 hours earlier, when checking in to your accommodation. This can be the same test used to enter the Canary Islands providing you check-in within the 72 hours of having taken the test.
download and activate the Radar COVID notification app throughout your stay on the islands, and for 15 days after your return home.
These measures are specific to the Canary Islands and apply to all guests aged 6 years and over, unless they have proof of travel confirming their uninterrupted presence on the islands for the previous 15 days. Any traveller failing to comply, risks being refused access to accommodation. For further information, refer to guidance from the Canarian tourist board, and check with your accommodation provider prior to travel.
You should not use the NHS testing service to get a test in order to facilitate your travel to another country. You should arrange to take a private test and should confirm with the testing facility the type of tests available prior to booking an appointment.
