Heating Experts Reveal Ideal Thermostat Temperature to Save £145 Annually
Ideal Thermostat Temperature to Save £145 a Year

Heating specialists have provided crucial guidance on the optimal thermostat settings for households, revealing that a simple adjustment could lead to substantial annual savings on energy bills. According to industry experts, maintaining room temperatures within a specific range and avoiding common usage mistakes can significantly reduce heating costs.

Optimal Temperature Range for Efficiency and Comfort

Nick Duggan, managing director at The Radiator Centre, emphasised the importance of temperature control. "The ideal temperature for a room is between 18-21°C. Every extra degree adds around 10% to the average heating bill, so it's vital to ensure your radiators are operating as efficiently as possible," he stated. This advice comes at a critical time, as it now costs approximately £600 more per year to heat properties compared to 2022 levels.

Expert Recommendations for Thermostat Usage

An Octopus Energy spokesperson highlighted common thermostat errors that waste energy. "Using it like an on/off switch or 'boost' button can actually waste energy, as the system works harder to reheat the space. You'll stay more comfortable—and use energy more efficiently—by setting it to come on only when needed and leaving it steady between 18-21°C," they explained. The spokesperson confirmed that turning the thermostat down by just one degree could save up to £145 annually.

Adam Knight, lead engineer at BOXT, offered practical advice for consistent heating. "Keep it simple and steady. Set the thermostat to a realistic target, about 18-20°C for most homes during the day, with a small adjustment for nighttime, usually around 16-17°C, rather than switching off completely," he recommended.

Substantial Savings Through Minor Adjustments

Ricky Sharma of Engineering Real Results (ERR), a training organisation for trades such as heating engineers and plumbers, reinforced the message of incremental changes. "Most homes are comfortable at between 18°C and 21°C, so if you usually keep it higher, try turning it down a little and adding an extra layer of clothing instead," he suggested. Sharma noted that lowering your thermostat by just 1°C could cut your bill by around 10%, according to the Energy Saving Trust, which equates to an average of £120 a year back in your pocket.

The collective expert consensus underscores that mindful thermostat management is a straightforward yet effective strategy for reducing energy expenditure. By adhering to the recommended temperature ranges and avoiding inefficient practices, households can achieve notable financial savings while maintaining a comfortable living environment.
