Before home electrical work: check the contractor, worker and completion papers

Before you start

EMSD requires appropriate registration for workers undertaking work on fixed electrical installations and provides separate contractor and worker registers. Contractor registration and the actual worker's qualification are different checks; grade, permitted work and scope must match the installation. A registered company's appearance in the database is not government endorsement of its pricing, workmanship or every quotation item. Combine the register check with a clear specification and document requirement for the job.

What to do, step by step

1. Describe the fixed installation, equipment and location and supply safe photographs and existing records for assessment. For communal areas, a rented unit or building capacity, ask the owner or management about permissions. Do not open an energised fitting or board merely to photograph the interior; investigation should be handled by the appropriately qualified person.
2. Obtain the contractor's and worker's formal names and registration numbers and check the separate EMSD registers. Ask how the actual worker's qualification fits the job and record the date and result. Clarify an unreadable certificate or business card before proceeding. A Business Registration record alone is not verification of electrical-work qualifications or suitability.
3. Require a written quotation covering materials, scope, interruption arrangements, testing, completion documents, payment stages and warranty responsibility, with prior approval for additional work. Compare like scopes rather than only headline totals. If circuit or capacity issues emerge, obtain the contractor's explanation and revised proposal before agreeing to an unrecorded expansion of the job or cost.
4. After work, obtain the required inspection, testing and certification through appropriately qualified personnel and confirm what document and submission apply. Check names, numbers, address, scope and dates and retain quotation, invoice and warranty records. A later defect can then be followed up against identifiable work and responsibility rather than a phone number without a job record.

Costs, timing, and things to check

A register search checks qualification and does not inspect the site. Clarify the worker's contractor relationship and permitted scope. Repeated trips, burning odour or unusual heat need suitable professional attention with the affected equipment stopped where safe. Fire, smoke or immediate danger requires the appropriate emergency response alongside later contractor and repair questions.

Completion certification, periodic inspection and communal-installation documents can differ. Ask which applies instead of assuming every household must submit the same form. Keep statutory documentation and a private warranty separately. Address pricing disputes with the quotation and evidence while ensuring a safety problem receives prompt professional investigation rather than waiting for the money dispute to conclude.

A practical example

An owner adding sockets during renovation checks both contractor and worker numbers. The quotation specifies circuit assessment, materials, testing and completion documents. At completion, the owner verifies the certificate address and scope and keeps warranty contacts, rather than treating a Business Registration certificate as the entire electrical qualification check.
