At 2:17 a.m., Sophie woke with the quiet certainty that something was off. No sound, no bad dream. Just a cold that had slipped into the bedroom and settled deep into her bones. She reached for her phone and checked the thermostat: 15°C. Earlier that night, she had proudly switched the heating off, telling herself, “It’ll save money.”
Under the duvet, she paused. Pull on a hoodie, or get up and turn the heating back on? How could a single button press suddenly feel like a financial calculation?
Eventually, she switched the radiator back on, feeling half irritated, half anxious about what it might mean for her next energy bill.
The next morning, the question surfaced—the one many people are quietly asking right now.
Is turning the heating off at night actually smart… or does it quietly make bills worse?
Switching heating off at night: smart saving or misleading habit?
On paper, the logic seems flawless. You’re asleep, wrapped in a duvet, the house is still, so you turn the heating off completely. Less runtime, less energy use, lower costs.
Social media repeats the idea endlessly. Videos show thermostats dropping from 21°C to OFF at bedtime. People slide under heavy blankets with hot water bottles, smiling as if they’ve unlocked a secret only the “smart” ones know.
The problem is simple: homes don’t behave like viral tips promise.
When the house cools too far
Marc lives in a 1990s semi-detached house with decent—but not perfect—insulation. Last winter, he decided to shut the heating off completely between 11 p.m. and 6 a.m. At first, the idea seemed to work. His boiler ran less overnight, and the energy app showed a small dip.
But when he looked at the full picture, the truth appeared. Each morning, there were sharp spikes from 6 to 9 a.m. as the system struggled to reheat cold walls, pipes, and radiators. By the end of the month, his gas bill hadn’t dropped at all.
Worse, he felt colder—shuffling to the kitchen wrapped in a blanket, wondering why the “smart” trick hadn’t paid off.
Eventually, he returned to a gentler night setting, left with the uneasy feeling that he’d been sold a too-good-to-be-true shortcut.

Why turning heating fully off can backfire
The reality is more subtle than most advice suggests. When heating is switched off entirely, it’s not just the air that cools. Walls, floors, and furniture lose heat too.
By morning, your system isn’t reheating a room—it’s recharging the entire building’s thermal mass. Depending on insulation and heating type, that cold restart can consume a surprising amount of energy.
A modern, well-insulated flat may handle a full shutdown well. An older, draughty home with electric radiators or a modest boiler may not.
The line between clever savings and a hidden trap is thinner than most slogans admit.
The night-time strategy that usually works better
For most households, the winning move isn’t turning heating off—it’s turning it down. Energy specialists typically advise lowering the temperature by 2°C to 3°C overnight rather than shutting the system down completely.
That might mean dropping from 20°C to 17–18°C while you sleep. This reduces consumption without letting the house fall into deep cold.
In the morning, your heating only has to climb a small hill instead of a mountain.
It’s less dramatic than extreme cold-sleep trends, but over time it tends to lower bills quietly and consistently.
How to make it effortless
The simplest solution is a programmable thermostat or built-in boiler schedule. Set a comfortable evening temperature, then let night mode begin 60–90 minutes before bedtime. Have it warm up again shortly before you wake.
Relying on memory rarely works. Automation removes the mental load, forgetfulness, and guilt.
If you rent or use basic electric heaters, timers or plug-in switches can still help avoid leaving them running all night.
“Completely switching heating off can work in specific homes,” says energy consultant Laura Bennet. “But for most people, a modest reduction is safer, more comfortable, and nearly as effective.”
- Lower the thermostat by 2–3°C overnight instead of switching it off
- Start night mode 60–90 minutes before bed
- Close curtains and shutters to keep warmth inside
- Block draughts under doors and in hallways
- Adjust by room: cooler bedrooms, warmer bathroom for mornings
Your home has its own personality
Once you pay attention, it becomes clear that every home behaves differently. Some flats stay warm for hours with minimal heating. Others turn icy fast. The same rule doesn’t suit both.
The smartest approach is simple experimentation. Try different night settings for a week or two. Watch morning temperatures, check your usage, and—most importantly—notice how you feel walking across the floor at dawn.
Your energy bill matters, but so does comfort in your own space.
Friends, neighbours, and social media will always swear by their own miracle trick. In the end, the right setting balances physics, insulation, budget, and tolerance for cold tiles.
You may discover your sweet spot is a gentle temperature drop, a good duvet, and never thinking about the boiler again at night. Or you might find that, in your well-insulated home, switching heating off for a few hours really does save money.
The real win comes when your heating habits match how your home actually behaves—not how a viral tip says it should.
