I wouldn't extrapolate.
Most places in Spain have and need heating, apart from a few coastal enclaves in the south. Spain is the 5th largest user of energy for residential heating in the EU, behind Germany, France, Italy, and Poland.

I did a quick search for more objective observations and what I found was:
Homes labelled A, B and C account for less than 10% of the housing stock. […] Most of households in the sample (52%) are E rated. F and G rated residences account for almost 25% of the sample. [1][2]
In Spain, buildings are currently responsible for 31% of energy consumption. […] the classification A - the highest - involves spending up to 10 times less than the G - the lowest -. Currently, in Spain most buildings have an E, F or G rating.[3]
