Unlike the other three, air conditioning doesn't reduce your bill — the figure shown is what it typically costs to run for cooling only. A £2,500 BUS grant may apply if an air-to-air heat pump replaces your main heating instead. Insulation models a combined loft top-up + cavity wall package (loft only for flats).
