Government subsidies available

Depending on your income and property, you may qualify for free or heavily subsidised insulation under the ECO4 scheme, a £7,500 grant toward a heat pump via the Boiler Upgrade Scheme, and 0% VAT on solar until 2027. Your ChillBill report checks eligibility automatically.

❄️
Air conditioning
Modern inverter AC units cool in summer and heat in winter as a heat pump — often cheaper to run than your boiler.
Typical saving: £200–£600/yr
🪟
Double glazing
Replace draughty single-glazed windows with modern A-rated units. Quieter, warmer, and less condensation.
Typical saving: £100–£200/yr
🏠
Insulation
Loft, cavity wall, and solid wall insulation. Often the fastest payback of any improvement — and may be free under ECO4.
Typical saving: £150–£400/yr

Solar panels
Generate your own electricity and earn from what you export. VAT is 0% on solar until 2027.

Replace your boiler with an air source heat pump. Up to £7,500 government grant available for eligible homes.
