With electricity prices at record highs, finding ways to reduce your energy consumption has never been more important. The good news is that there are many practical steps you can take to lower your bills without sacrificing comfort. From free behavioural changes to smart investments that pay for themselves, this guide covers 15 effective ways to cut your electricity costs.
Quick Wins (Free or Low Cost)
1. Switch Off Standby
Devices on standby can account for up to 10% of your electricity bill. TVs, games consoles, phone chargers, and computers all draw power even when not in use. Get into the habit of switching off at the socket, or use a standby saver plug that cuts power automatically.
Potential saving: £65+ per year
2. Only Boil What You Need
Kettles are one of the most energy-hungry appliances in the home. Boiling a full kettle when you only need one cup wastes significant energy. Fill only what you need – most kettles have minimum fill markers.
Potential saving: £15-25 per year
3. Wash at 30°C
Modern detergents work effectively at 30°C, and heating water accounts for about 90% of a washing machine's energy use. Dropping from 40°C to 30°C can reduce energy consumption by up to 40%.
Potential saving: £20-30 per year
4. Air Dry When Possible
Tumble dryers are among the most expensive appliances to run. Using a clothes airer or outdoor line instead can save substantial amounts. If you must use a dryer, ensure clothes are well spun first and clean the lint filter regularly.
Potential saving: £60-100 per year
5. Use the Eco Setting on Dishwashers
Eco programmes use less water and lower temperatures, saving energy while still cleaning effectively. Also, only run the dishwasher when it's full.
Potential saving: £15-20 per year
Lighting Improvements
6. Switch to LED Bulbs
If you haven't already, replacing all your bulbs with LEDs is one of the best investments you can make. LEDs use up to 90% less energy than incandescent bulbs and last 25 times longer. Start with the bulbs you use most.
Potential saving: £50-100+ per year (depending on number of bulbs)
7. Use Natural Light
Make the most of daylight by keeping curtains open and positioning desks near windows. Clean windows let in more light. Consider lighter wall colours that reflect light better.
Potential saving: Variable, but every bit helps
8. Install Motion Sensors
Motion-activated lights in hallways, bathrooms, and outdoor areas ensure lights are only on when needed. No more leaving lights on in empty rooms.
Potential saving: £20-40 per year
Heating and Cooling
9. Use Electric Heating Wisely
If you use electric heating, ensure you're only heating rooms you're using. Use timers to avoid heating an empty house. Consider whether a lower temperature with an extra jumper might be acceptable.
Potential saving: Significant – heating is typically the biggest energy cost
10. Manage Your Hot Water
If you have an electric immersion heater, use a timer to heat water only when needed. Insulate your hot water tank if it isn't already. Consider whether you need water as hot as it's currently set.
Potential saving: £30-50 per year
Appliance Upgrades
11. Choose Energy-Efficient Appliances
When replacing appliances, look for the highest energy rating you can afford. An A-rated fridge-freezer uses significantly less electricity than an older model. The energy label shows estimated annual running costs.
Potential saving: £50-150 per year per appliance
12. Right-Size Your Appliances
A larger fridge or freezer than you need wastes energy. Similarly, a washing machine that's too big means running half-empty loads. Choose appliances sized for your actual needs.
Potential saving: Variable
Smart Technology
13. Install Smart Plugs
Smart plugs let you control devices remotely and set schedules. You can ensure devices are off when you're out and monitor which appliances use the most power.
Potential saving: £30-50 per year
14. Use a Smart Thermostat
If you have electric heating, a smart thermostat learns your schedule and preferences, optimising heating to avoid waste. Many can be controlled remotely, so you never heat an empty house.
Potential saving: £75-150 per year
Electrical System Improvements
15. Get an Electrical Health Check
An inefficient electrical system can waste energy. Loose connections create resistance and heat, and outdated wiring may not be optimised for modern use. A professional inspection can identify issues and improvements.
Our EICR inspection service assesses your electrical installation and can identify efficiency improvements.
Understanding Your Usage
Before you can effectively reduce your bills, it helps to understand where your electricity goes. The biggest consumers in most homes are:
- Heating and hot water (if electric): 40-50%
- Wet appliances (washing machine, dishwasher, dryer): 15-20%
- Cold appliances (fridge, freezer): 10-15%
- Lighting: 10-15%
- Consumer electronics: 10-15%
- Cooking: 5-10%
Smart meters and energy monitors can show you exactly what's using power, helping you target the biggest savings opportunities.
Bigger Investments
For those willing to invest more upfront for long-term savings:
Solar Panels
Generate your own electricity and reduce dependence on the grid. With battery storage, you can use solar power even when the sun isn't shining. Payback periods have shortened significantly as electricity prices have risen.
Battery Storage
Store cheap off-peak electricity (or solar generation) for use during expensive peak times. Particularly valuable if you're on a time-of-use tariff.
Heat Pumps
Air source heat pumps are 3-4 times more efficient than direct electric heating, producing 3-4 units of heat for every unit of electricity used.
EV Smart Charging
If you have an electric vehicle, smart charging during off-peak hours can dramatically reduce charging costs. Our EV charger installation service includes smart chargers with scheduling capabilities.
Time-of-Use Tariffs
Some electricity tariffs offer cheaper rates at certain times (typically overnight). If you can shift energy-intensive activities to these periods, you can save significantly:
- Run washing machines and dishwashers overnight
- Charge EVs during off-peak hours
- Heat water overnight with an immersion heater timer
- Use battery storage to capture cheap electricity
Conclusion
Reducing your electricity bills doesn't require dramatic lifestyle changes. By combining several of the tips in this guide, you could save hundreds of pounds per year. Start with the free and low-cost options, then consider investments that will pay for themselves over time.
The key is to be conscious of your energy use and make informed choices. Every kilowatt-hour you don't use is money saved and carbon emissions avoided.
