Winter Energy Saving Tips for UK Homeowners

Practical advice to keep your home warm and energy-efficient during the cold months, while keeping bills manageable.

Why Winter Efficiency Matters

When temperatures drop, heating bills often rise — especially in homes that lack proper insulation or use outdated heating systems. But you don't have to sacrifice warmth to save money.

With a few smart changes and available support through UK government grants, you can stay comfortable and reduce your energy spend.

1. Insulate to Eliminate Heat Loss

Loft insulation can save up to £355 per year in a detached home (Energy Saving Trust).

Cavity wall insulation is equally effective — many homes still lack it.

Don't forget room-in-the-roof or flat roof insulation where applicable.

💡 Free insulation upgrades may be available through the ECO4 and GBIS schemes — even if you're not on benefits.

2. Use Your Thermostat Strategically

Lowering your thermostat by just 1°C can cut energy bills by around 10%.

Use heating controls or a smart thermostat to heat only the rooms in use.

Keep doors closed to retain warmth in occupied areas.

3. Curtains and Draught-Proofing

Close thick curtains at dusk to trap heat.

Use draught excluders for doors and windows.

Check for gaps around letterboxes, chimneys, and skirting boards.

These simple fixes are low-cost and can make your home feel instantly cosier.

4. Don't Block Radiators

Avoid placing furniture directly in front of radiators.

Bleed radiators regularly to release trapped air and ensure even heat.

Bonus tip: use reflective radiator panels to bounce heat back into the room.

5. Switch to LED Bulbs

Lighting accounts for up to 15% of a typical energy bill.

LED bulbs last longer and use around 75–80% less energy than halogen.

They're a small investment with big long-term savings.

6. Service or Upgrade Your Boiler

A modern condensing boiler is over 90% efficient.

Old boilers (10+ years) may waste up to 35% of energy.

You could qualify for a free boiler upgrade under the ECO4 scheme if your current one is inefficient or broken.

7. Consider a Heat Pump

Heat pumps are up to 3x more efficient than gas boilers.

While installation costs can be high, government grants of up to £7,500 are available through the Boiler Upgrade Scheme (BUS).

8. Apply for Government Support

You may be eligible for:

ECO4 – Offers insulation, boiler upgrades, and heat pumps to low-income or vulnerable households.

GBIS – Helps a wider range of homeowners and tenants access free insulation.

Local Authority Delivery schemes – Provide targeted support in specific regions.
