What paperwork will I receive after commercial electrical work?

The documents you receive depend on the work completed. They normally include the appropriate electrical certificate, test results and a clear record of any defects or recommendations. We issue paperwork that identifies the installation, the work carried out, the tests completed and the person responsible for the inspection.

For a new installation or alteration, you’ll usually receive an Electrical Installation Certificate. This records the extent of the work and confirms which design, construction and inspection checks were completed. It can cover items such as a new distribution board, additional circuits, fixed equipment, lighting or an electrical refurbishment.

The certificate is supported by a schedule of inspections and test results. This gives the measured results behind the certificate rather than simply stating that the work passed. Depending on the installation, the records can include checks for continuity, insulation resistance, polarity, earth fault loop impedance and RCD operation.

For a small alteration, we may issue a Minor Electrical Installation Works Certificate. This is used where the work is limited in scope and does not require a full installation certificate. The document still identifies what we changed and records the relevant inspection and test results.

For an inspection of an existing installation, the main document is an Electrical Installation Condition Report. An EICR records the condition of the wiring and equipment at the time of inspection. It lists observations using the relevant classification codes, so you can distinguish an immediate danger from a matter that needs attention or further investigation.

An EICR does not certify that every part of a building is new or defect-free. It reports what we inspected, including any limitations such as inaccessible areas, equipment that could not be isolated or information that was unavailable. Those limitations matter when a landlord, insurer or managing agent reviews the report.

If we find a dangerous or potentially dangerous fault, the report will show it clearly. We explain what the finding affects and what work we recommend. If remedial work is agreed, we provide the relevant certificate or completion record for that work rather than altering the original inspection findings.

Other documents may apply where they form part of the job. These can include test certificates for emergency lighting, records for fixed electrical equipment, circuit schedules, updated distribution-board labels, commissioning information or a handover pack. We only include records for systems we have inspected, installed, tested or commissioned.

The paperwork also helps someone else understand the installation later. A circuit schedule can show which protective device supplies each circuit. Test results provide a baseline for a future inspection. Drawings or marked-up records can show changes that are not obvious once ceilings, plant rooms or service areas are back in use.

For a commercial property, keep the certificates with the building’s compliance records. Landlords, property managers and facilities teams may need them when arranging future maintenance, planning alterations, responding to an incident or demonstrating that inspections have been completed. An EICR is a condition report, not a substitute for ongoing maintenance or the next inspection required for the property.

Our NICEIC registration and ECA membership support the electrical work and certification we provide. In practical terms, that means the records identify the work properly and give the person managing the building useful evidence of what was checked, tested and changed.

Before work starts, we can explain which documents apply to the proposed job. If the scope changes during the work, we record the change so the final certificate matches the installation that is actually left in service.
