Cut energy waste safely

£0 setup: review a bill, then check lights, heating, windows, doors and appliances. An audit can identify cost-effective measures; results vary by home.

£0: adjust the thermostat while asleep or away. A 7–10°F setback for 8 hours may save up to 10% on heating. Low-cost LEDs may save $200+ a year on average.

Drafts: caulk fixed cracks or weatherstrip movable joints. Check your lease first; ask the landlord before property changes. Ducts, wiring or damaged outlets? Call a pro.
