VOLTAGE
VERIFICATION
Complete voltage verification testing services — confirming nominal voltage levels, phase-to-phase and phase-to-neutral values, and voltage drop compliance across all distribution points.
Overview
Confirm Every
Volt — Precisely.
Voltage Verification Testing measures and confirms that nominal voltage levels are present at all distribution points — verifying phase-to-phase, phase-to-neutral, and phase-to-earth values against design specifications.
Our engineers perform voltage checks at main intake panels, distribution boards, sub-distribution boards, and final circuit outlets — ensuring voltage drop remains within BS 7671 limits (typically 3% for lighting, 5% for power).
Accurate voltage verification prevents equipment malfunction, reduces energy losses, and confirms the installation is ready for safe operation and handover.
