The best time to put your heating on is generally when you start to feel cold indoors or when the outside temperature consistently drops below around 15°C. This usually happens around mid-September to mid-October in many places. Experts often recommend setting your heating to come on about 30 minutes before you wake up in the morning or before you arrive home, and to turn it off when heating is no longer needed. Indoor temperatures below 18°C often signal it's time to turn heating on, especially for vulnerable people like the elderly or those with medical conditions. Additionally, starting heating before cold snaps helps prevent issues like frozen pipes and mold growth in the home. The clock change in late October is a common marker for many households to turn on heating, but local weather and personal comfort should drive the decision. In summary:
- When indoor temperatures start feeling cold or go below 18°C.
- When outdoor temperatures drop below 15°C (commonly mid-September to mid-October).
- About 30 minutes before you need the home warm.
- Earlier if there are vulnerable people or if your home is poorly insulated.
This approach balances comfort, health, and energy efficiency.
