This dataset provides aggregated volumes of smart and non-smart meters connected to the National Grid Electricity Distribution network and includes SMETS1, SMETS2 and non smart meters.

There are two main types of smart meters – the older models known as SMETS 1 (Smart Meter Equipment Technical Specifications) and the newer versions that were rolled out in 2018, known as SMETS 2. While SMETS2 meters offer many of the same benefits as SMETS1 meters, they contain the most up-to-date technology to help make life easier – especially if you ever want to switch supplier.
