Taking your useful example, Hartington, that means:
Taxes (i.e. to governments, i.e. "taxes" as in the normal sense of the word):
GB APD - 5.00
Spanish Security tax (I'm assuming, as AENA is State-controlled) - 1.00
Not sure about Spanish airport service charge - I would see this as a normal landing fee.
So GBP6.00 out of GBP41.70 is real "tax", the rest are just normal elements of airline operating costs which the airlines misleadingly group with "tax" to make the headline fare look lower.
