Energy monitors

Which? has put 10 energy monitors through thorough lab tests to find out which are best-designed to help you save money on your energy bills.

If you want help cutting your electricity usage, a Best Buy energy monitor could help. We’ve tested a variety of energy monitors – including the Owl CM160, the Efergy Elite, Current Cost’s Trec and Npower’s Smartpower – and have only awarded Best Buy status to the very best models.

Which? energy monitor expert Hazel Cottrell says: ‘The most revealing thing we found in our tests is just how different each energy monitor is. While some are designed brilliantly and offer a wealth of handy usage data, others offer very limited information on-screen.’

Find out which monitors we rate as Best Buys in our energy monitor review. Here you can also find out more about energy monitor features and see an energy monitor in action in our video guide.

Energy bill savings

According to the Energy Saving Trust’s small-scale trials, energy monitors can typically help households save 5-15% on their annual electricity bill – on a £500 annual bill, that’s from £25 to a noticeable £75.

However, Hazel advises: ‘An energy monitor itself won’t cut your bills – it relies on you using the information it provides to actively change your behaviour – so the savings you make are completely down to your actions.

‘Check out our energy monitor user reviews to see the varying success that five Which? members had when we sent them energy monitors to try out.’

Best Buy energy monitors

Energy monitors need to be accurate and consistent, but because they require you to change your behaviour in order to cut your energy usage, they also needs to be easy to use and offer usage information in an effective way.

We’ve awarded Best Buys to four top-scoring energy monitors that have proved they can report electricity usage accurately and consistently, as well as presenting the information in a useful and easily understandable way.

To find the best energy monitor to suit your needs, you can also use our compare energy monitors tool, which allows you to search for an energy monitor that offers particular features – such as allowing you to download your data to a computer, or use individual socket monitors.
