Households could save up to £90 a year by lowering thermostats, says OVO Energy

In the face of rising energy costs, OVO Energy recommends reducing thermostat settings by just one degree and adopting simple measures like draught-proofing to significantly cut household heating bills.

As households across the UK continue to face rising energy costs, OVO Energy has shared a simple yet effective heating tip that could potentially save consumers up to £90 annually. Central to their advice is the recommendation to reduce the thermostat by just one degree—a small adjustment that can lead to significant savings over the course of a year. This guidance was issued as part of a wider set of cost-saving tips aimed at helping households manage their energy use more efficiently amid escalating expenses.

According to OVO Energy, turning down the thermostat by one degree is an easy way to save both fuel and money. “Keeping an eye on your thermostat and turning it down when you don’t need it is an easy way to save fuel and money on your bills,” the energy firm stated. They also emphasised the benefits of smart thermostats, which allow users to control heating remotely through smartphones or tablets, enabling more precise temperature regulation. Additionally, utilising room thermostats and thermostatic radiator controls can prevent energy waste by heating only the rooms in use, rather than maintaining a single temperature throughout the entire home.

This approach is reinforced by other providers, such as Octopus Energy, which similarly advocates thermostat adjustments as a means to curb energy wastage. According to Octopus, reducing the thermostat by one degree could save as much as £145 annually, a figure notably higher than OVO’s estimate. Octopus further advises maintaining the thermostat within an optimal range of 18-21°C and cautions against frequent thermostat toggling, which can lead to inefficiency. Their guidance succinctly states: “You’ll be comfier and use your energy more efficiently if you set it and leave it on for when you need it.”

Beyond thermostat management, both companies highlight draught-proofing as a critical strategy to prevent heat loss and thus reduce the need for constant heating adjustments. Gaps around doors, windows, and chimneys can lead to significant warmth escaping from a home, effectively negating the savings from lowered thermostat settings. Octopus Energy estimates that addressing such draughts can save around £80 per year. They suggest simple DIY methods such as using fabric excluders or thermal cameras to spot leaks, some of which are available to borrow from local councils or libraries. Effective draught-proofing traps warmth inside the home, allowing heating to be used more efficiently and sparingly.

Smart thermostats, such as OVO Energy's promotion of the tado° Smart Thermostat, represent another layer of optimisation, capable of reducing heating bills by up to 28%. These devices adapt to weather forecasts, usage patterns, and even trigger alerts when occupants leave or return to the home, helping avoid unnecessary heating. This technology can provide significant insights and control over energy consumption, enhancing traditional thermostat functions.

Additional energy-saving recommendations from OVO Energy include simple behavioural adjustments such as switching off appliances at the wall to save around £35 annually, washing clothes at 30°C to save £9, and reducing shower time by a minute, which can save a family of four approximately £75. Similarly, Octopus Energy advises setting boiler flow temperatures between 55 and 60 degrees, air drying clothes instead of using tumble dryers, and using energy-efficient lighting, all contributing to substantial savings.

It’s worth noting that mismanagement of heating systems can be costly—an article from GB News warns that common mistakes like inefficient boilers, poor thermostat placement, and outdated timer settings could collectively cost households up to £1,480 annually. Preventative actions such as annual boiler servicing, radiator balancing, and correctly positioning thermostats to avoid heating empty rooms are essential for maximising any efficiency gains from behavioural changes or technology upgrades.

In summary, while the precise savings from lowering thermostat settings vary between energy providers like OVO and Octopus, the consensus is clear: modest temperature reductions, proper draught-proofing, and leveraging smart technology can substantially reduce energy bills. These measures, coupled with broader energy-conscious habits, offer households practical ways to ease the financial burden of heating costs in an uncertain economic climate.
