Honest about gas comparison

At standard electricity rates (24.5p/kWh), a heat pump in DH7 may cost around £167 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 £221-527/year

Insulating first reduces heating demand, tipping the balance in favour of heat pumps.
