What Happens During an Electrical Safety Inspection?

A step-by-step view of access, testing, limitations and the final report

Quick answer

An electrical safety inspection begins by agreeing the extent and limitations, reviewing available records and identifying the installation. The electrician then visually inspects accessible parts, safely isolates circuits for testing, records observations and produces a report with the outcome, classifications and recommended next steps.

Before the inspection

The contractor should confirm the property, reason for inspection, occupied areas, operational constraints and access. Existing certificates, circuit schedules and previous reports are useful. In a business or communal building, shutdowns may need to be coordinated.

The client and inspector should agree any limitations. Locked rooms, inaccessible accessories, sensitive equipment and inability to isolate circuits can restrict the inspection and should be recorded.

Visual inspection

The electrician examines accessible components for damage, deterioration, overheating, unsuitable alterations and missing protection. The inspection may include the consumer unit or distribution board, representative accessories, earthing and bonding arrangements and visible cable routes.

This is more than a quick look at the fuse box. The extent should be sufficient to support a meaningful assessment, subject to the stated limitations.

Electrical testing

Testing may require circuits to be switched off and equipment disconnected. It can include continuity, insulation resistance, polarity, protective-device and earthing-related checks as appropriate. The exact tests depend on the installation and safe access.

Sensitive equipment should be identified beforehand. The electrician will balance meaningful testing with the risk of damage and record any limitations.

Observations and classifications

Defects and concerns are recorded with clear locations and descriptions. C1 identifies danger present, C2 a potentially dangerous condition, C3 an improvement recommendation and FI a need for further investigation without delay. The overall result depends on the observations.

The report should be factual. A quotation for remedial work is a separate commercial document.

Preparing the property

  • Provide access to the consumer unit, meters and relevant rooms.
  • Move furniture away from a representative sample of sockets where practical.
  • Tell the inspector about alarms, medical equipment, servers and other sensitive systems.
  • Gather previous reports, certificates and alteration records.
  • Plan for temporary loss of power and notify occupants.
  • Ensure keys and building-management permissions are available.

Good preparation reduces limitations and repeat visits.

After the report

Ask the inspector to explain the outcome and priorities. Obtain a separate remedial scope where necessary, and keep all completion documents with the original report. If the report contains FI, arrange the additional investigation promptly rather than treating it as a minor note.

The next inspection date should be recorded in the property's maintenance system.

Frequently asked questions

Will the power be turned off?

Usually, at least some circuits need isolation for meaningful testing. Agree shutdown arrangements in advance.

Will walls or floors be opened?

An EICR is generally based on accessible inspection and testing rather than destructive opening, unless a separate investigation is agreed.

How long does an inspection take?

It depends on size, circuit count, access, records, condition and operational restrictions. A fixed time estimate without these details may be unreliable.
