10 Ways to Heat Your Home More Efficiently This Winter
Practical tips to stay warm while keeping energy bills under control during the coldest months.

Winter heating accounts for over half of the average UK household's energy bill. Here are 10 proven ways to stay warm without watching your costs spiral.
1. Turn Down by 1°C
Every degree you lower your thermostat saves around 10% on heating costs. Most people can't tell the difference between 21°C and 20°C.
| Temperature | Annual Cost* | Comfort Level |
|---|---|---|
| 22°C | £1,400 | Too warm for most |
| 21°C | £1,260 | Recommended max |
| 20°C | £1,135 | Ideal for most |
| 19°C | £1,020 | Comfortable with layers |
*Based on average 3-bed house with gas heating
Tip
Use OhmMy's temperature tracking to find your comfortable minimum. Many people find 19-20°C works well with appropriate clothing.
2. Heat Only Occupied Rooms
If you have thermostatic radiator valves (TRVs):
- Living areas: Full heat when in use
- Bedrooms: Lower temperature (16-18°C)
- Unused rooms: Frost protection only (12°C)
Closing doors between zones helps maintain temperature differences.
3. Time Your Heating Right
Don't heat an empty house. Program your heating to:
- Morning: Warm up 30 mins before you wake
- Daytime: Off or reduced if everyone's out
- Evening: On when people return
- Night: Off or reduced for sleeping
Info
Smart thermostats learn your patterns. OhmMy integrates with Hive, Nest, and Tado to show heating alongside your other energy data.
4. Use Curtains Strategically
Free heating from the sun:
- Daytime: Open curtains on south-facing windows
- Evening: Close all curtains as soon as it gets dark
- Thick curtains can reduce heat loss through windows by 25%
5. Bleed Your Radiators
Air trapped in radiators reduces efficiency significantly:
- Turn off heating and let radiators cool
- Use a radiator key to open the bleed valve
- Close when water (not air) comes out
- Check pressure and top up if needed
Signs you need to bleed: cold spots at the top, gurgling noises.
6. Don't Block Radiators
Heat gets trapped behind:
- Furniture pushed against radiators
- Long curtains covering radiators
- Clothes drying on radiators
Leave at least 10cm gap for air circulation.
7. Draught-Proof Everything
Common heat escape routes:
- Letterboxes: Fit a brush or flap
- Keyholes: Use covers
- Door gaps: Install draught excluders
- Floorboard gaps: Fill with sealant
- Loft hatch: Add insulation strips
Success
DIY draught-proofing typically costs under £50 and saves £30-50 per year. Payback in one winter!
8. Insulate, Insulate, Insulate
If you haven't already:
| Insulation Type | Cost | Annual Saving | Payback |
|---|---|---|---|
| Loft (270mm) | £300-400 | £180 | 2 years |
| Cavity wall | £400-600 | £160 | 3 years |
| Hot water tank | £20 | £35 | 7 months |
| Pipe lagging | £10 | £10 | 1 year |
Check for grants—many homes qualify for free insulation.
9. Service Your Boiler
An annual service ensures:
- Maximum efficiency
- Safe operation
- Valid warranty
- Longer lifespan
A well-maintained boiler can be 10-15% more efficient than a neglected one.
10. Consider a Heat Pump
For the long term, air source heat pumps offer:
- 300-400% efficiency (vs. ~90% for gas)
- Lower running costs with cheap electricity
- Zero direct emissions
- Government grants up to £7,500
Warning
Heat pumps work best in well-insulated homes with underfloor heating or oversized radiators. Get a proper assessment before switching.
Track Your Progress
Use OhmMy to monitor:
- Gas consumption trends over winter
