Update: This story was updated on September 22 to reflect the fact that as of September 20, it will no longer be necessary to fill in the health control form in order to travel to Spain nor to present the QR code generated from the form when boarding (or on arrival). The Spanish Ministry of Health has announced an extension to the Coronavirus entry restrictions for travellers from non-European Union countries, valid until November 15.
In line with the current rules in force, all travellers of 12 years or over, from third countries, (including those from the UK), will be required to present a vaccination certificate, a negative COVID test, or a recovery certificate on arrival. This does not apply to passengers in transit.
The Ministry says the vaccination certificate is recognised as long as it proves that the holder completed primary vaccination in the last 270 days or has received a booster shot.
A recovery certificate is accepted as long as it proves that the holder tested positive for the virus in the last six months.
Regarding entry using a COVID test, Spain accepts both PCR and rapid antigen tests. The PCR test must have been taken within the 72 hours before entering Spain, whereas the rapid antigen test must have been taken 24 hours before entering Spain.
