Building Network Operator

Building Network Operator (BNO)

The Building Network Operator (BNO) standard needs to be adhered to in order for your local electrical DNO to be able to connect supplies to your building.

Orange Fox Electrical BNO Specialists team can offer you a full BNO service for new and existing installations. Our dedicated, BNO-trained engineers can design, install and maintain new riser and lateral sub-main cabling networks to meet your needs.

We ensure that the installation provided is fully compliant to your local BNOs standards and that the installation complies with BS7671.  We mimic the installation process that was previously provided by the network operators, and work with them to ensure the same set of standards and correct equipment and cable is used.

BNO Standards

BNO Standards

UK Power Networks have introduced a single standard for multi-occupancy buildings, to be effective across all three of their Distribution Network Operator (DNO) regions. UK Power Networks have also introduced another single standard for the connection of new services above 100 amps, including the introduction of metering CTs (Current Transformers) within the service cut out equipment. In addition, these changes have now been adopted by most other DNOs.
