What appliances can be switched off?

Many appliances can be safely switched off while some require case-by-case judgement. The focus is on delivering energy savings without creating operational, safety, or compliance risks.

The key principle is simple:
Not everything should be treated the same. Context, usage, and risk matter

Appliances That Are Typically Safe to Switch Off

These appliances are generally suitable for scheduled shutdowns (e.g. overnight, weekends):

- Monitors and TVs
- Laptop, phone, and appliance chargers
- Printers
- Bottle fridges (drinks only, no food)
- Electric heaters
- Coffee machines
- Vending machines (non-fresh food)
- Electric food heaters (catering)
- Dehumidifiers

These devices often consume energy unnecessarily when left on and represent low risk, high-impact savings opportunities.

Appliances That Can Be Switched Off With Conditions

Some appliances are commonly switched off, but only under the right circumstances:

• Fridges - Do not switch off if food is stored overnight or at weekends, can be switched off where fridges are empty or used only during working hours.

• Hot Water Taps - Safe to switch off overnight and at weekends, No Legionella risk when reheated to boiling How does turning off water boilers and zip taps affect legionella risk?. Do not switch off for extended periods (weeks or months).

• Boilers - Safe to turn off overnight and at weekends. Not suitable for long-term shutdowns

• Desktop Computers - Commonly switched off in schools and universities. Very old equipment may be excluded due to hardware concerns. Older desktops often highlight upgrade opportunities, as they consume significantly more energy than modern equivalents.

• Air Conditioning (Split Systems) - Internal air delivery units can be switched off. External condenser units should remain powered. Energy savings still achieved by stopping air delivery
