Small Changes, Real Savings

Energy bills are one of those costs that feel fixed — but they're actually more within your control than most people realise. The changes below don't require a major investment or lifestyle overhaul. Many cost nothing at all and can reduce your usage meaningfully over the course of a year.

1. Switch to LED Lighting Throughout Your Home

LED bulbs use around 75–80% less energy than traditional incandescent bulbs and last significantly longer. If you haven't already made the switch, this is the single easiest change you can make. The upfront cost per bulb is modest and the energy savings accumulate every day.

2. Use Your Thermostat Smarter

Dropping your heating thermostat by just 1°C can reduce your heating energy usage noticeably over a winter. Programmable or smart thermostats make this effortless by automatically adjusting temperature based on your schedule — no heat wasted in an empty house.

3. Tackle Standby Power (Phantom Load)

Devices left on standby still draw electricity. TVs, games consoles, phone chargers, and desktop computers all contribute to a "phantom load" that runs 24/7. Using power strips with on/off switches makes it easy to cut power to a cluster of devices at once.

4. Run Appliances on Off-Peak Tariffs

If you're on a time-of-use tariff (such as Economy 7 or a smart meter-based variable rate), running dishwashers and washing machines overnight or early morning can cost significantly less. Check whether your tariff offers cheaper off-peak hours.

5. Keep Your Fridge and Freezer Well-Maintained

  • Ensure door seals are airtight — a worn seal lets cold air escape and forces the compressor to work harder.
  • Defrost your freezer regularly if it's not frost-free.
  • Keep the back of your fridge clear so heat can dissipate efficiently.
  • Avoid placing hot food directly in the fridge — let it cool first.

6. Wash Clothes at Lower Temperatures

Modern detergents are formulated to work effectively at 30°C. Dropping your wash temperature from 40°C to 30°C uses noticeably less energy per cycle — and for most everyday laundry, the results are identical. Reserve higher temperatures for heavily soiled items or bedding.

7. Draught-Proof Your Home

Draughts around doors, windows, and letterboxes force your heating system to work harder. Draught-proofing strips and door seals are inexpensive to buy and simple to install. This reduces both heat loss and the energy your boiler or heat pump needs to maintain a comfortable temperature.

8. Use Your Oven More Efficiently

  • Batch cook and use the oven for multiple items at once.
  • Avoid opening the oven door unnecessarily — temperature drops significantly each time.
  • Consider a microwave, air fryer, or slow cooker for smaller meals: these use a fraction of the energy of a full oven.

9. Check Your Water Heating Settings

Hot water heating can be a significant portion of your energy bill. If your boiler or water heater is set higher than necessary (60°C is generally recommended for safety; above that is wasteful), lowering it slightly can save energy. Also consider insulating your hot water cylinder if it isn't already.

10. Monitor Your Usage With a Smart Meter

You can't manage what you can't measure. A smart meter and its in-home display let you see energy usage in near real-time, which makes it much easier to identify which appliances or habits are driving your bill. Many energy suppliers offer smart meter installation at no charge.

Putting It All Together

None of these tips requires a dramatic change in how you live. Implemented together, they can make a meaningful dent in your annual energy costs. Start with the no-cost changes — thermostats, standby power, wash temperatures — and work from there.
