I remember a landlord friend complaining that he'd done all the cavity
wall and loft insulation, etc., that the authorities demanded, then when
the inspectors came they marked the "cavity wall insulation" entry as
"presumed not". They didn't even ask.

I don't have an EPC.
Detached 1911 bungalow, significantly extended in 70s and readjusted in
80s to make the extensions more sensible. Quite a mix of structure
including original brick cavity walls, modern lightweight walls and
timber in the first floor. Cavity insulation, and as much loft
insulation as we could fit (which isn't that much), underfloor
insulation. 151m^2, 213kW/m^2. That includes cooking and hot water all
year and our hot water is on a pumped secondary ring main, so loses more
heat than most.
We have the room heat fairly low evenings and weekends, and just 10C at
all other times.
