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 that can be installed for the duration of an inspector’s visit to a property experiencing voltage fluctuations. The voltage trend needs to be transmitted to the inspector’s mobile phone or laptop.

The key requirements for the voltage monitoring device are:

  1. To be safe to be left plugged into a standard 13A socket unattended while the inspector carries out his checks
  2. To collect RMS voltage data for the duration of the inspectors visit allowing for a voltage profile to be displayed
  3. To have the ability to connect to a pre-existing portal such as iHost and begin transmitting voltage data immediately upon connection
  4. To use mobile 4G or similar communication technology for real-time data transmission
  5. To be stored in a protective case
  6. That it is priced similarly to a multi meter, ie less than £100.

Deadline:

The deadline for this opportunity 17 June 2025. Please submit your proposal above.
