Some older smart meters, called Non SMETS Smart (NSS), can only be read by the supplier that installed them. If we've invited you to book a smart meter installation it's because your property has these meters and we need to replace them with second generation 'SMETS2' meters.

There are different types of smart meters:

Non SMETS Smart (NSS)

These can only be read by the installing supplier and that will not change. Bulb or any other supplier you choose in the future will not be able to read this type of meter. We recommend replacing these meters with second generation 'SMETS2' meters, which can be read by any supplier.

First generation (SMETS1)

We aren’t replacing first generation (SMETS1) smart meters with second generation (SMETS2) ones.

If your smart meters were installed before February 2019, they’re likely to be SMETS1.

We can automatically read SMETS1 meters that have the manufacturer’s name ‘Secure’ printed on them. But we can’t read other SMETS1 meters just yet. There’s a nationwide fix happening that should allow us to read all SMETS1 meters by the end of April 2021.

Second generation (SMETS2)

This is the type of smart meter we are installing. It can be read by any supplier, so even if you decide to switch away from Bulb in the future, it will stay smart.
