KEY POINTS

  • Use the checklist for the supply service you are requesting.
  • Keep names, capacities and drawing revisions consistent.
  • Track application, installation and energisation as separate milestones.

A complete application begins with a consistent set of customer and engineering information. These five checks help prepare a submission for discussion with the responsible electricity office. They are planning checks, not a guarantee of approval.

1. Confirm the applicant and site documents

Identify the legal applicant and authorised signatory. Check the site address, company details and the owner’s consent where applicable. Ask for the current document list for the requested connection or capacity change rather than reusing a checklist from a different type of application.

Keep one register showing each document, its owner and whether it is ready. Use MEA e-Service or PEA’s published customer guidance to start the process.

2. Reconcile the drawings and equipment information

Check that the single-line diagram, load schedule and equipment specifications describe the same installation. Mark the current revision, identify changes from the existing system and confirm the required engineering sign-off. Resolve differences in transformer capacity, breaker ratings or connection details before submitting the package.

3. Explain the load calculation

List current equipment, proposed additions, operating patterns and future loads that are included in the brief. Record the assumptions used for maximum demand. Keep a distinction between the power rating of installed equipment and the demand expected when it operates.

If the equipment selection changes after submission, ask the responsible designer whether the calculation and application need to be updated.

4. Identify the connection and approval boundaries

Confirm the service area and actual supply arrangement. A tenant or factory in an estate may also need permissions and information from the building or estate operator. Identify who provides the incoming supply works, who owns the customer installation and who responds to comments on each part.

Our MEA and PEA planning guide explains the initial service-area check.

5. Link the application to the programme

Track submission, clarification, equipment procurement, construction, inspection and energisation separately. Ask the responsible office about the dependencies and anticipated dates for this site. Neither early submission nor a complete package establishes a universal approval time.

Before booking commissioning, confirm that the supply works and customer installation will both be ready and that the relevant inspections have been arranged.

A practical submission register

For each outstanding item, record the document or drawing reference, required action, responsible person and target date. Keep the accepted version alongside the comments it resolves. This gives the owner, designer and contractor a shared record of what remains to be done.

ETES can discuss the electrical installation scope using your site information and available drawings. Confirm which design, submission and coordination activities are included in the proposal.

Common questions

How long will the application take?

Request a site-specific estimate. Network works, document completeness, equipment availability and inspection arrangements can all affect the programme.

Can we submit a preliminary design?

Ask the responsible office what can be reviewed at each stage. Clearly distinguish preliminary information from the final documents needed before installation or energisation.

Who should own the application tracker?

Appoint one coordinator, while keeping technical and legal sign-off with the responsible people. Record this division in the project brief.
