It is generally recommended to put the heating on when the outside temperature drops below about 15°C (59°F). Many people start turning on their heating around mid-September to October when outdoor temperatures regularly fall to this range. Indoor temperatures below around 18-21°C (64-70°F) are often considered a sign to switch on the heating for comfort. Personal preference, home insulation, and who is living in the home (such as older adults or those with medical conditions) also influence this decision. Additionally, some people wait until the clocks go back in late October as a seasonal cue to start heating.
Key Temperature Guidelines:
- Outdoor temperature below 15°C is a common threshold to start heating.
- Indoor temperature falling below 18-21°C indicates a need for heating for most.
- Some experts recommend turning on heating when it feels cold, especially for vulnerable people.
- Heating is often turned on around mid-September to October depending on climate and personal comfort.
- Homes with poor insulation or drafts may require heating sooner.
Other Considerations:
- Pay attention to the weather forecast for cold snaps.
- Set thermostat around 18-21°C for comfort and energy efficiency.
- Consider energy-saving measures like draught-proofing and insulation to reduce heating needs.
Overall, the best indicator is when it starts feeling cold inside, generally correlating with outside temperatures dropping below about 15°C, adjusted for personal and household needs.
