Domestic Voltage Monitoring - house showing electrical distribution

Domestic Voltage Monitoring

What is the Problem?
As the UK aims to achieve net zero by 2050, low carbon technology (LCT) like EV chargers and heat pumps are being installed at a significant rate (around 3.5m new connections each year). This rapid growth is causing more customer complaints about voltage levels falling outside of the regulatory limit of 230 V +10%/-6%.

Currently, UK Power Networks (UKPN) use a qualified inspector to install a voltage recorder in the customer’s home for two weeks. The device is then collected and the data analysed; a slow and resource-heavy process.

Preferred output
UKPN want a voltage monitoring device customers can install themselves, allowing for quicker identification and resolution of voltage-related complaints.

The key requirements for the voltage monitoring device are:

• To be safe for customer use when plugging into a standard socket
• To record maximum, minimum and average voltage readings at predefined intervals (eg five minutes)
• To be able to switch between the interval settings
• To be able to connect to a pre-existing portal (such as iHost) and begin transmitting voltage data immediately upon connection, allowing early complaint validation
• To use 4G or similar communication technology for real-time data transmission
• To be light and small enough to be protectively packaged and shipped by post
• That it is priced similarly to a multi meter.
