The actual fix (without becoming obsessive)
You don't need to unplug your fridge. Focus on the big offenders:
- Set-top boxes — turn off at the wall when going to bed. Modern Sky/Virgin boxes restart in 30 seconds; older boxes need a minute or two
- Games consoles — switch off "Rest Mode" / "Quick Resume". Saves £25–£35/year per console
- Soundbar + AV stack — put on a single switched extension lead so one click kills them all
- Microwaves with clocks — pull the plug if you don't use the timer
- Chargers — unplug when nothing's charging (the 0.3W per charger adds up across 6+ devices)
Don't bother with
- Phone chargers when actively charging — they use what the phone needs
- Wi-Fi routers — turning off saves £19/year but breaks smart heating, alarms and overnight backups
- Fridges, freezers, alarms, smoke detectors — keep on
Smart plug ROI
A pack of 4 smart plugs costs ~£25 and lets you schedule the entertainment stack and printer to cut completely overnight. Saves typically £35–£60/year. Payback under 6 months.
The 5-minute weekend audit
- Walk around with a £15 plug-in energy monitor (or borrow one from your library)
- Note any device drawing >5W on standby
- Add to a switched extension lead or smart plug
- Done. £50+/year saved permanently.

What exactly is "standby power" and why is it a problem?
Standby power is the electricity used by devices when they are "off but not really off." Many electronics continue to draw a small amount of power even when not actively in use, leading to wasted electricity and higher bills.
How much could I realistically save by tackling standby power in my home?
The average UK household wastes £55–£90 a year on devices left on standby. By focusing on the biggest offenders like set-top boxes, games consoles, and soundbars, you could save a significant portion of this.
Recommended Smart Energy Plug
Monitor appliance electricity usage in real time and identify expensive devices around your home.
View on Amazon UKAre smart plugs a worthwhile investment for reducing standby consumption?
Yes, smart plugs offer a good return on investment. A pack of four costing around £25 could save you £35–£60 annually by allowing you to completely switch off certain devices overnight. This means they typically pay for themselves in under 6 months.
Which devices should I prioritise turning off at the wall or unplugging?
You should prioritise older Sky/Virgin set-top boxes, games consoles in rest mode, and soundbars attached to a single switched extension lead. Also, consider unplugging microwave clocks and phone chargers when not in use.
Should I bother turning off my Wi-Fi router to save money?
While turning off your Wi-Fi router could save you around £19 a year, it's generally not recommended. Doing so would disrupt smart heating, alarms, and overnight backups, which are often essential for modern homes.
