With rising energy bills, it’s no wonder more people are asking if it’s cheaper to leave the heating on low all day, rather than turning it on only when needed. This question comes up every winter, and it’s easy to see why. Nobody wants to spend money heating an empty house, but nobody enjoys coming home to freezing rooms either.
So, what’s the truth behind this? Let’s take a closer look with some practical energy cost saving advice.
Is It Cheaper to Keep the Heating on Low All Day?
For most homes, the answer is straightforward: no, it’s not.
The Energy Saving Trust, one of the UK’s leading authorities on household energy use, confirms that leaving your heating running on low all day usually ends up costing you more. This happens because your home continuously loses heat throughout the day, especially if insulation is poor or outdated. Even at a low temperature, keeping your heating on for extended periods will burn through more energy, and more money.
Generally speaking, it’s best to turn your heating on only when you actually need warmth to keep your home warm without overspending.
What About the Idea That Reheating Your Home Costs More?
This myth pops up regularly. People often assume that letting their home cool down and then reheating it again consumes more energy than maintaining a consistent low temperature. However, modern boilers, especially efficient condensing models, heat your home quickly and cost-effectively. If your heating system is well maintained, it won’t struggle to bring your house back to a comfortable temperature in a short time.
Money-saving expert Martin Lewis backs this up, advising homeowners to simply “turn the heating on when you need it.”
Practical Ways to Keep Your Home Warm for Less
Here are some easy ways to keep your home warm and your heating costs down without leaving the heating running all day:
1. Use Timers or Smart Thermostats
Program your heating to switch on shortly before you wake up or return home. Smart thermostats, like Nest or Hive, let you control heating remotely, ensuring you use energy only when it matters. This means you’re not heating an empty home or forgetting to switch the heating off when you leave.
2. Improve Insulation and Stop Draughts
Insulation makes a huge difference. Make sure your loft is insulated, seal draughty windows and doors, and close curtains in the evenings to keep heat inside.
3. Keep Your Boiler Serviced Regularly
A boiler in good condition uses less energy and saves you money. At Aren Heating & Plumbing, we recommend an annual service to ensure your boiler is running efficiently, safely, and reliably. Regular servicing is one of the best ways to improve the efficiency of your gas boiler and avoid higher running costs over time.
4. Only Heat Rooms You Actually Use
Adjust radiator valves in rooms you rarely use. Keeping your living areas warm rather than heating every single room in the house saves energy and money.
Are There Any Situations Where Keeping Heating on Low Is a Good Idea?
In certain cases, yes. Homes with poor insulation, older buildings, or those suffering from damp or condensation problems might benefit from constant low heating. Keeping a steady, gentle warmth helps reduce condensation, preventing dampness and mould growth. If you’re experiencing these issues, talking with a heating professional can help you find the best solution.
