£500 for what? Total cost for a month? A year? The monthly average of a full year of costs. The monthly average cost thing is common in NL; people often have no clue other than knowing the monthly average cost. And it's often estimated beforehand by the energy company. It's assumed to be correct.
Anyway, people need to check the SCOP instead of figuring out if it is efficient (COP) at a certain temperature.

Oh please no.
On UK, I was in Scotland. I thought the homes in NL are often terrible quality. Scotland was another level. Pretty much no insulation, terrible windows. Really drafty. Yet the media (as a result the public as well) hates the "Insulate Britain" movement.
The number of homes that could have improvements in insulation for tiny costs is astounding, but somehow insulating a home is some lefty woke thing.
