Honest about gas comparison
At standard electricity rates (24.5p/kWh), a heat pump in BA2 may cost around £27 more per year to run than a gas boiler. However:
- Off-peak tariffs (Octopus Cosy at 7.5p/kWh) make heat pumps cheaper than gas
- Gas prices are volatile — heat pumps protect against future price rises
- Heat pump lifespan (20+ years) vs gas boiler (12-15 years) saves on replacements
- If you're on oil or LPG, you'll save £267-499/year
Insulating first reduces heating demand, tipping the balance in favour of heat pumps.
