Why heat pumps cut carbon
Burning gas, oil or LPG releases CO₂ directly in your home. A heat pump uses electricity, and the UK grid is far cleaner than it was — and getting cleaner every year. So a heat pump's carbon footprint is much lower today and keeps falling over its lifetime, even as a gas boiler's stays the same. For homes on direct electric heating, the efficiency gain alone cuts emissions sharply.
