Electricians – Mains Work Inspections (ROI)

Sparkies! Carried out mains work? Upgrading a switchboard, upgrading mains cable, or hammering in a new electrode? Let's get you sorted with an ROI today.

High-risk mains work electrical inspection, including ROI certification compiling and High Risk Database (Energy Safety) submission. Applies to mains work only.

Before we arrive, make sure your testing and documentation are ready: main earth identified and tagged, electrode location listed on the switchboard and accessible, earth continuity under 0.5 ohm, mains polarity and earth fault loop impedance tested, and your ESC/COC on site. Ask us for the full pre-inspection checklist when you book. Re-inspection charges apply if items are missed and we need to return.

Note: we are not MEPs. Metering work must be carried out by a network approved inspector, and we can recommend one in your area.
