•The payback time for both retrofit scenarios is less than five years.•The operational carbon stage contributes significantly more than the embodied carbon stage.•Current regulation requirements are inadequate to meet the zero-carbon goals for dwellings.•Adding heat pump to the shallow retrofit incr...
