Obviously not all homes are suitable for this. Not all people buying a home will want the maintenance burden, the insurance risk is higher. I have a massive solar array on a house in a very sunny country and even in winter there the cost benefit is limit. In most of England it's nearly pointless. This doesn't mandate battery storage, making it almost literally pointless.

So many people complain about the high cost of housing, but the government keeps adding more and more requirements, regulations, and hoops to jump through.

Currently in the process of expanding my non-attached garage, and had to expand power and add a breaker box to it. Was required to include an EV circuit as part of the baseline to reach code. I have zero interest, or need, for an EV circuit in this garage since it's used to house collector muscle cars. Don't want it, don't need it, still have to pay for it just to be able to do the expansion.

(don't get me started on how long and how many back-and-forths the permitting process took)
