antigen test

Could I take a Covid 19 antigen self test pack provided by the NHS in England with me to Spain to self test myself in Spain before flying back to Stanstead to avoid the worry of having to send off PCR and possibly not getting it back before the return flight

No, you can’t use the free NHS tests, you need a certificate showing your details and the NHS tests don’t provide this service.
either buy a local test in Spain or take a test out with you, from the list of gov approved suppliers that will require video or photo evidence of your test result before issuing your certificate.

The guidance is very clear https://www.gov.uk/guidance/coronavirus-covid-19-testing-for-people-travelling-to-england

NHS tests

NHS tests cannot be used for the purpose of pre-departure testing before travel to England.

You cannot take an NHS test abroad with you to use on yourself before you return.

Yes unfortunately the two posters above are correct. On the plus side, private antigen tests are much cheaper than PCRs.

If you go on the tripadvisor forum you might get some tips on where to get tested in the location you are staying in Spain.
