At Brookhouse Gas, we often get asked by homeowners considering heat pump servicing in Worksop whether switching off their heat pump overnight can save energy and money. It’s an understandable question—after all, we all like to reduce bills while keeping comfortable. However, the answer is not as straightforward as it might seem, and it depends on your home, the outside temperature, and the efficiency of your system.
Heat pumps work differently from conventional gas or oil boilers. Instead of generating heat from fuel, they transfer heat from the air or ground into your home. This process is most efficient when the system can maintain a steady temperature rather than having to work hard to reheat a cooled space in the morning.
Understanding how heat pumps use energy
To understand if turning off your heat pump saves energy, it’s helpful to consider how it operates. When left on, the system maintains a moderate heat output, balancing comfort and efficiency. But when it’s turned off overnight, the internal temperature drops significantly. The next morning, your heat pump must work overtime to bring the home back to a comfortable temperature—often consuming more electricity overall.
Because of this, many experts recommend keeping your heat pump running, even at a slightly reduced setting during the night. This steady-state operation can be more energy-efficient because it avoids intense energy demand spikes associated with reheating.
Should I turn off my heat pump at night to save money?
This is one of the most frequently asked questions from our clients in Worksop. The honest answer is: usually not. Instead of completely turning it off, lowering your thermostat by a small amount (1–2°C) overnight is often a better strategy.
Modern heat pumps designed for British climates are optimised to maintain efficiency at steady levels of operation. When the unit shuts down entirely during cold weather, frost buildup may occur, and the system will need extra energy to defrost and reheat. Over time, this pattern can not only increase your energy costs but also put unnecessary strain on components, potentially leading to more frequent heat pump servicing needs.
When might you consider switching off your heat pump?
There are a few scenarios where turning off your heat pump may make sense:
- When you’re away from home for several days, such as during a holiday.
- If outdoor temperatures remain mild overnight and you can comfortably maintain heat in your property without assistance.
- For temporary energy-saving experiments—monitoring usage via smart thermostats can reveal if small adjustments make a noticeable difference.
Otherwise, consistent operation is generally recommended to ensure system stability and occupant comfort.
How proper servicing ensures better efficiency
Regular servicing is key to maintaining your heat pump’s efficiency and longevity. A professional inspection at least once a year helps ensure that your unit operates safely and effectively throughout every season. Tasks such as cleaning filters, checking refrigerant levels, and inspecting coils prevent performance drops that can increase running costs.

The more familiar you become with how your system works, the easier it is to adjust settings for comfort and savings.
Final thoughts: the best overnight heating strategy
In short, turning off your heat pump overnight rarely saves energy—in many cases, it might even cost more. Lowering your thermostat slightly instead of fully shutting it off is usually the more efficient approach. This method helps maintain system balance and avoids straining the compressor or other components.
Regular maintenance, monitoring smart controls, and consulting an experienced installer are all smart ways to keep your heat pump performing optimally across changing seasons.
