I totally feel for this guy. But the real crime here is successive governments that have completely failed in holding the housebuilders to account with tougher specs for new build houses.

Why the hell a 2020 newbuild house needs any space heating at all is beyond me. Should just be passive, with electric heater for the shower.

The big picture is that we are shipping great wealth to fuel-producing countries because politicians are too lazy or corrupt to insist on modern building methods and standards that are properly enforced.
