A PCR test is the more expensive one, you only need an antigen test at app €40.
I believe that the Farmacia in La Fuente are doing this, ask them to print you a certificate.
You will also need a day 2 test when you arrive back in the uk and no quarantine.
The day 2 test should be purchased before you leave Spain as there will be a unique reference number in the confirmation email which you have to use when you fill in your locator form for the uk, this form should only be completed within the last 48 hours of your stay in Spain.
You will also need a copy of your double vaccination from the NHS app.
The above is the current rules for adults living in England, I do not know anything of the rules for kids or other Countries.
