Whether you heat with electricity, gas, or another source, winter energy bills can skyrocket. Even with a strict budget, they hit hard. The good news? Simple, low-cost strategies can minimize heat loss and trim your costs significantly.
Here are 10 expert tips to save substantially on heating. Read on:


The simplest way to lower your bill? Dial back the thermostat. Aim for 19°C (or lower) instead of 23°C, and add a sweater for comfort. Dropping just 1°C saves 7% on heating costs.
Pro Tip: DIY hand warmers from socks: Fill one sock with rice, tuck it into another (open end down), microwave for 30 seconds, and enjoy 15 minutes of warmth.

Up to 12% of heat escapes through gaps in doors and windows. Grab foam or rubber seals from your hardware store and apply to frames. Add door sweeps for bottom gaps.

Single-pane windows leak heat despite seals. Double-glazing costs a lot, but temporary film is affordable and easy: Apply adhesive side to glass, shrink with a hairdryer. In a pinch, use cling wrap or bubble wrap.

Thick curtains and shutters block drafts like our grandparents did. Open south-facing ones daytime for solar gain; close others and all at night. This reduces heat loss by 10%.

Exterior-wall outlets create hidden leaks. Remove covers, seal gaps with foam or silicone, add outlet gaskets, and reattach.

Pipes through walls, floors, and ceilings let in cold air. Inspect and fill gaps with caulk or foam, especially under sinks and to unheated areas like basements.

Water heating is 17% of energy use. Set to 49°C to save 5% per 4°C drop. Insulate the tank (avoid controls), and descale regularly for efficiency.
