The exception is for old housing stock which isn't well enough insulated to be heated by a heat pump, and there's huge amounts of single glazed, poorly insulate

  Doesn't that lack of insulation affect all heating and cooling technologies? Seems kind of orthogonal to me. Where insulation is poor, people - individually and/or through the government - absolutely should be investing first on improving it. But once that's done, we're back to the original question of what technology to use for heating or cooling the now-well-insulated space. Note that it's entirely possible e.g. for a furnace to have a greater capacity to heat a space while still being less efficient at it within any but the most extreme ranges.
