Here’s how we calculated this possible saving:
• The average UK household spends £646 per year on their gas bills based on 15,000 kWh consumption.[1]
• The average semi-detached house in the UK saves £540 and the average detached house saves more than £800 on their heating bills when they replace a ErP G rated boiler with an A rated one.[2]
• Switching to a new Vaillant ecoTEC boiler operating at a maximum of 94% efficiency could reduce your energy use by 30%.[3]

These are estimated figures based on installing a new A-rated condensing boiler with a programmer, room thermostat and thermostatic radiator controls (TRVs) in a gas heated home from an older boiler with a programmer and room thermostat. Savings will vary depending on the size and thermal performance of your home.
Figures are based on fuel prices as of October 2022.
