Why Network Health Matters

Risks, Dealt With

We conduct detailed inspections, including thermal imaging and humidity testing, so you can spot hidden risks like overheating or degradation before they cause failure.

No Delays

As an SIP-accredited provider, we can de-energise and safely re-energise supplies, and install isolators ourselves. This bypasses external delays, meaning your work is done safely and on time.

Smart Upgrades, Simple Integration

We handle specialist upgrades – from EV chargers and smart metering in crowded rooms, to tenant-level sub-metering – integrating them into your network with ease.

Total Peace of Mind

Our dedicated team offers immediate help with 24/7 phone support, plus rapid on-site emergency response should any issues arise.

Your BNO Journey. Fully Guided.

We undertake detailed inspections, including fuse condition assessments, thermal imaging and humidity testing, to minimise network risks.

We install Residual Current Devices (RCDs), Residual Current Breakers with Overcurrent (RCBOs), Surge Protection Devices (SPDs) and Arc Fault Detection Devices (AFDDs) to shield against shocks, fire and equipment damage.

You receive support for smart upgrades, such as EV charging, smart metering in crowded rooms and tenant sub-metering.

We complete mandatory Electrical Installation Condition Reports (EICRs), meaning your network is legally compliant, every 5 years.

You get 24/7 phone support and on-site emergency response to tackle urgent issues fast.
