BS 7671 is the UK wiring standard. An Electrical Installation Certificate (EIC) certifies only the new or altered work described on it. An Electrical Installation Condition Report (EICR) reports on an existing installation within its recorded extent and limitations. A Minor Electrical Installation Works Certificate can record a minor alteration that does not include a new circuit.

When testing may come first

  • Missing records do not by themselves prove that an installation is unsafe, and they do not automatically mean a full EICR is needed.
  • For work beyond a simple like-for-like replacement, targeted inspection and testing may be recommended first when the records do not give useful information about the circuit. Sometimes an EICR is the better starting point.
  • The checks depend on the proposed work and may cover the relevant circuit, protective device, earthing and bonding. Agreeing this first can reduce surprises in the plan and price.

What the completed work should record

  • Every repair receives the checks relevant to the work itself. A focused fault visit is not automatically a whole-home inspection.
  • Keep every page of a certificate or report, including circuit schedules, test results, extent and limitations.
  • An installation built to an older standard is not automatically unsafe or automatically in need of replacement.
  • For work that needs electrical inspection, testing, certification or notification, we arrange the appropriate registered professional and confirm responsibilities before work starts.
