Smart meter
Smart meter- Distribution Network Operator (DNO) guidance for service upgrades
If you already have a smart meter installed, you should be aware that as a result of upgrading your electricity supply to a three-phase supply (via a service upgrade request), your electricity supplier will need to replace your existing single-phase smart meter with a three-phase meter.
This may result in loss of some, or all of the smart services currently provided by your electricity supplier. You should contact your electricity supplier to tell them you are upgrading your electricity supply to a three-phase supply, and your electricity supplier will be able to advise you of the options available to you, including whether they are able to provide you with a three-phase smart meter, and whether they will be able to continue with the provision of smart services once your electricity supply has been upgraded.
