Your devices still use power when they’re turned off. It’s called standby power, and it can add 10-15% to your bill. Your TV, laptop charger, phone charger, even your microwave — all sucking power while doing nothing.
The Free Solution:
Unplug them when you’re not using them.
How to do it:
- Unplug your phone charger when your phone is at 100%

Free Hack #2 — Use Natural Light & Curtains

This is another powerful free energy saving hack for renters that uses what you already have.

Open your curtains. Use natural light.
How to do it:
- Open curtains as soon as you wake up

Free Hack #3 — Find the Energy Thief

This is the most important free energy saving hack for renters because it shows you exactly where your money is going.
The Problem:
You don’t know which appliance is costing you the most. Could be an old fridge. Could be a heater. Could be your gaming PC.
The Free Solution:
Do a 24-hour energy audit.
How to do it:
- Write down every appliance you use in 24 hours
- Note how long you use each one
- Check the wattage on the back of each appliance
- Calculate: (Watts × Hours used) ÷ 1000 = kWh
Example:
A 100W light bulb used for 5 hours = (100 × 5) ÷ 1000 = 0.5 kWh. At £0.30 per kWh, that’s £0.15 a day.
How much can you save with this free energy saving hack for renters?
Once you find the energy thief, you can replace it or use it less. Zero cost to find it. This free energy saving hack for renters alone can save you £20-50 a month.
Pro tip: Your fridge, heater, and gaming PC are usually the biggest energy thieves. Check them first. This free energy saving hack for renters takes 10 minutes and pays off forever.
