The 5-year period refers to how often the inspection is typically carried out — not the inspection itself.
- Based on guidance from BS 7671 (IET Wiring Regulations)
- Common for many commercial environments
- May vary depending on building type, usage, and risk
Typical guidance:
- Commercial buildings: every 3–5 years
- Industrial environments: often more frequent
- Rental properties: fixed at 5 years by law
In simple terms: the EICR is the report, and the 5-year period is a common inspection interval.
