The usual advice for a high energy bill boils down to “be colder” — turn the heat down and put on a jumper. Sometimes that’s fair, but most homes are leaking money in ways that have nothing to do with how warm you keep them. You can cut a meaningful chunk off the bill by fixing where the heat escapes and where energy gets wasted, without spending your winter shivering. Here’s how to lower your energy bill without being cold, starting with the free fixes.
Key takeaways
- Most waste is heat escaping and appliances running inefficiently — not the thermostat being too high.
- Draught-proofing and a few habit changes are free or cheap and pay back fast.
- A programmable thermostat lets you heat the house when you’re in it and not when you’re not — comfort and savings at once.
Stop the heat escaping (free to cheap)
Heating a home that leaks warmth is like filling a bath with the plug out. Before touching the thermostat, close the gaps:
- Draught-proof doors and windows. Cheap self-adhesive strips around frames and a draught excluder at the bottom of doors stop the cold air that makes you crank the heat up.
- Close the curtains at dusk. Windows lose heat fast at night; thick curtains drawn as it gets dark trap a surprising amount of warmth for free.
- Block unused chimneys and vents. An open, unused fireplace is a hole in your ceiling. A chimney balloon or draught excluder seals it.
- Only heat the rooms you use. Turn radiators down in spare rooms and keep their doors shut so you’re not paying to warm empty space.
Take control of the thermostat — smartly
You don’t need to be cold; you need to stop heating an empty house. A programmable or smart thermostat lets you warm the place for when you’re actually home and awake, and ease off when you’re out or asleep under a duvet. Even a small, well-timed reduction — a degree lower, or heating that switches off an hour before you leave — adds up across a season without you ever feeling the difference. It’s the opposite of shivering: it’s not wasting heat on rooms and hours that don’t need it.
Catch the quiet energy vampires
Heating isn’t the only drain. A few habits trim the rest of the bill:
- Wash clothes on a cooler cycle — most of a washing machine’s energy goes on heating the water, and modern detergents work fine cold.
- Switch to LED bulbs; they use a fraction of the energy and last for years.
- Turn off “standby” devices at the wall — TVs, consoles, and chargers sip power around the clock.
- Only boil the water you need, and put lids on pans — small kitchen habits that quietly add up.

Frequently asked questions
What’s the cheapest way to lower my energy bill?
Draught-proofing is the best value — cheap strips and a door excluder stop the heat loss that makes you turn the thermostat up, so you feel warmer while using less energy. Pair it with closing curtains at dusk and only heating rooms you use, and you’ll see a difference with almost no spend.
Does turning the thermostat down really save much?
Yes, but you don’t have to be uncomfortable to benefit. The biggest savings come from not heating the home when nobody’s there or awake, which a programmable thermostat handles automatically. Even a modest, well-timed reduction adds up over a heating season without you noticing the cold.
Start with the free stuff this week — draught-proof the worst door, close the curtains at dusk, and knock the empty rooms down a notch. You’ll spend nothing, stay just as warm, and watch the next bill come in lower.
