I’m wondering if we will end up with something like this in our flat once gas is made prohibitively expensive/banned. there is a central flue running up the middle of the building and a vent from the cupboard around it into each room from the original warm air gas boiler (removed) so there is space/ducting and a source of air. obviously you need everyone in the building to stop pumping boiler exhaust into the flue...
what additional heat source are you planning?
Mr_Smyth-
Will you be able to get your windows to meet the requirements?

I'm still waiting on a decent government backed scheme before we remove the gas line.
We could use an air source heat pump as the background heating demands will be much lower, but I'm also not against using PV for hot water and/or heating with overnight electricity top-up (if that ever comes back).
We'll have a sealed 'eco' wood burner in the lounge (drawing air from under the suspended floor) for some interim heat and a 'single warmer room' option if we decide to keep the background heating low.

Yep, continuous background ventilation with 98% heat retained. No need to punch holes in the external walls (100mm PIR).
We'll be well beyond the performance of an average new build at around £1k materials and many days of faffing! Should pay for itself in ~2 years.
