Smart meter data access and privacy

Smart meters don’t use the internet. Instead, they use their own secure communications network, and transfer information in a similar way to how your mobile phone sends and receives text messages. This wireless connection is designed by cyber security experts to be very secure. In fact, It is encrypted to prevent hackers being able to access your information. 

Smart meters use a secure smart meter data network, known as the Wide Area Network, which the DCC manages, to send usage readings automatically and wirelessly to your energy supplier, so you receive accurate, not estimated bills. This wireless connection is encrypted to prevent hackers from being able to view your smart meter data or breach your smart meter privacy. 

Smart meters send readings on a half-hourly, daily or, in some cases, monthly basis. Only your energy supplier can receive your meter readings and only at intervals arranged between you and them. If your energy supplier needs to share your smart meter data with a third-party, you will be notified and can opt-out (however this could effect your supplier's ability to service you).

See the DCC's explanation for more information on how smart meters send readings. 

• You can access your smart meter data, using your smart meter and in-home display. You should always have access to your energy use data and be able to control who else can access it.
• You might also be able to access your data through third-party apps, such as those provided by some suppliers. To use these apps, you would need to give the app permission to access your data.
• Your energy supplier can receive your meter readings from your smart meter, but only at intervals arranged between you and them.
  • Your supplier may choose to use a third-party to collect your consumption data on their behalf. The third-party cannot use your consumption data for any other purposes that sending it to your supplier. Your supplier will let you know if this is going to happen.
• Energy network operators can access some anonymised energy use data. This data cannot be traced back to you. Network operators use this data to understand energy use patterns so they can manage the network more efficiently.

Because smart meters are secure, it is unlikely anyone else would be able to hack into your smart meter to access your smart meter data. The smart metering system was designed in partnership with cyber security experts to prevent hacking as much as possible. While no electronic device can be 100% protected, smart meters are as safe as they possibly can be. 

Check out the DCC's website for more information about protecting data on the smart meter network. 

Smart meters are usually installed in the same place as your analogue meter. This may be in a cupboard, or even outside your front door. Inside your home, you may be given an in-home display (IHD). The IHD simply displays data from your smart meter - it cannot record information.

So, there you have it: all your smart meter data and information about your energy use is strongly protected. The smart meter data is transmitted safely, using a dedicated and secure wireless network. 

You can get in contact with your supplier if you want to change how often you share your secure smart meter readings. If you have given them permission to do so, your energy supplier may use this information to offer you tailored energy efficiency advice and improve the service they provide for you.
