If you already have a smart meter, you may need to have a replacement fitted before 2024. This is because your older smart meter may not meet the technical specifications required by the UK Government.
Some older smart meters are not easily switched between suppliers and won’t necessarily allow you to have access to future data services, such as advanced time of use tariffs.
Second generation smart meter models, known as SMETS2 smart meters, will allow you to access all these services.
If you need to upgrade your smart meter, your energy provider will get in touch with you and will either install a new meter or upgrade your smart meter remotely. Your energy provider will do this at no cost to you.
