Are smart meters safe?

Smart meters are relatively new technology, so you may be concerned about their effect on your home and family’s safety. Rest assured, there’s no need to worry.

The smart meters we use at OVO are extremely safe. They are covered by UK and EU product safety legislation, which means they’ve undergone rigorous testing to make sure they are stable and secure.

Do smart meters emit radio waves?

Smart meters use low-frequency radio emissions to communicate the information they collect, in a very similar way to other wireless electronic devices, like mobile phones, wi-fi computers and televisions.

Public Health England, an executive agency of the UK Department of Health, has collated various studies, reviews and assessments to measure the effect of smart meter radio waves. They have concluded that:

  • All the evidence so far suggests that the radio waves produced by smart meters don’t pose any risk to the health of people who have them in their home

  • Using a mobile phone would give you greater exposure to radio waves than living with a smart meter

  • Smart meters aren’t communicating all the time – just in occasional short bursts when they’re actually sending us information

  • You would get higher exposure to radio waves from any device you use closer to your body, which emits more power and which transmits for more of the time – such as a mobile phone.

If you’d like more details, please take a look at the Public Health England (PHE) guide to smart meters.

Is my data safe?

Yes. We use encryption, controlled access and other security, including ways agreed with the government, to make sure the information transmitted from your smart meter is always secure. There are strict new regulations and codes of practice, governed by Ofgem, to keep mart meter data private and safe, and all your personal data is safeguarded by the Data Protection Act.

Your smart meter uses its own secure, wireless network, known as a home area network (HAN), that works in the same way as other wireless systems in your home. It then uses a wide area network (WAN) to send the data to your energy supplier. This works in the same way your mobile phone sends and receives information.
