According to a decision by the EU Parliament, by 2030 all residential buildings in the EU should at least meet the criteria of class E. From 2033, residential buildings should achieve energy efficiency class D on average. This means that owners would have to retrofit now, but there are no clear rules yet.

A heat pump would therefore require less electricity. But here, too, the delay in the Heating Act is causing uncertainty. It is still unclear what funding there will be.
