What is the Best Temperature for Your Home in the UK?

Wondering what temperature to set your heating for comfort, energy savings, and health? Here’s the UK expert guide to the best home temperature for every season, room, and family.

Recommended Room Temperatures (UK Guidance)

• Living rooms: 19–21°C (66–70°F) for comfort and efficiency
• Bedrooms: 16–18°C (61–65°F) for healthy sleep
• Bathrooms: 21–23°C (70–73°F) for warmth after showers
• Hallways/unused rooms: 15–18°C (59–65°F) to prevent damp

Seasonal Settings: Winter vs Summer

• Winter: Aim for 18–21°C in living spaces. Lower at night or when away—smart thermostats can do this automatically for you.
• Spring/Autumn: 17–19°C is usually enough as outside temperatures rise.
• Summer: Most UK homes switch off heating, but use smart controls to keep hot water efficient and boost only if needed.

Comfort vs. Efficiency: How Low Can You Go?

• Every 1°C reduction in thermostat setting can save up to 10% on your heating bill.
• Many people find 19°C comfortable—try lowering your usual setting by 1°C for a week and see if you notice a difference.
• Use smart thermostats for automatic temperature drops at night or when the house is empty.

Health & Safety: Avoiding Cold Risks

• NHS Guidance: Main living areas should be at least 18°C, especially for elderly, babies, or those with health conditions.
• Avoid “cold homes”: Temperatures under 16°C can increase risks of respiratory illness, damp, and discomfort.
• Don’t heat unused rooms to the same level as living areas, but avoid letting them drop below 15°C to prevent mould and pipe freezing.

See why smart thermostats make setting and maintaining healthy temperatures easier—automatically.
