Zombies can make as much as 50% of your bill. Do you know if you have many on them in your house?

They are devices that are usually on even when you go to bed, including those in standby mode.

If 1 Watt of electricity 24hrs/day costs about £1.20 a year, a 40W load could be costing you up to £50 a year.

How to find the zombies:

  1. Switch off any appliances as you would if you were going to bed - also turn off your fridge/freezer.
  2. Record the load (W/kW) shown on your electricity display – in a typical home we’d expect the remaining load to be in the range of 150W-250W.
  3. Now, go round your home and switch off everything else – gaming consoles, phone chargers, clock radios, and other devices left in standby mode. How low can you go on your electricity display? You should be able to get close to zero.
  4. Then switch only the things you really need back on (but not your fridge/freezer yet!) and record the load on the electricity display.
  5. Look at the difference between the two readings. Every 1W you have reduced = more than £1 a year saved.
  6. Now remember to switch your fridge/freezer back on!


To win an Amazon voucher, you have until the 7th of November to create a post below about the zombies you found.

The author of the most up-voted post will receive a £25 Amazon voucher; and another £25 voucher will go for the most interesting contribution (as picked by the DecarboNet project)!

This contest is now closed but you can still discuss the baseline consumption of your home below. You can also win a £25 until the 10/12/2016 by posting an highly up-voted tip or participate in an existing discussion.

The main zombies in my place are the ones that can't easily be turned off. We turn off what we can at the wall when not in use, for example the TV and AV system.

We have a fairly high base load and many of the culprits are hard-wired in:

  • Mains powered smoke alarm system
  • Active ventilation system that can't be switched off
  • Built-in fridge and freezer with no easy access to sockets
  • Oven and hob with no isolator switches
  • Boiler

Other things to look out for are doorbell transformers and alarms. Battery powered ones can be better, or at least one in a socket that can be turned off.
