Was planned for 2025.
It is the usual case of one hand not knowing what the other hand is doing.
Take two brand new properties, identical in every way apart from the heating system. Property 1 has gas central heating and Property 2 has electric heating.
Property 1 will have an EPC rating of C at worst and possibly B. Property 2 will have an EPC rating of D at best and sometimes E (the minimum standard which permits property to be marketed for sale or let).
The government wants to improve energy performance and eventually will increase the minimum standard to D and then C over the next 20 years. If you don't meet the standard, you need to improve the property.
So how do you improve the electrically heated house?? It's almost impossible to improve a pre-existing property by more than a single grade - maybe two if the gas heated house has no insulation. But how do you improve a brand new house if it already has pretty much all the available features to save energy?
The system is flawed.
