Level 3 ASP Design Sydney
What a Level 3 ASP Designer Does
A Level 3 ASP is the only contractor authorised by Ausgrid and Endeavour Energy to design new and altered customer connections, network infrastructure, and power-quality studies. We prepare the engineering drawings, calculations, single-line diagrams, protection settings and supporting documentation that the network needs to approve your project — from a single new commercial connection through to a multi-stage subdivision. We design it, then our Level 1 ASP team can install it.

Understanding The
Method of Supply (MoS) Document
Before design work can properly begin, the network assesses available capacity, connection points and fault levels for your site and issues a Method of Supply document. This sets the technical boundaries your Level 3 designer must work within — it's worth reviewing carefully alongside your designer to confirm it matches your site constraints, staging plan and future load growth, since a mismatch here can cause costly redesign later.

- Direct liaison with Ausgrid or Endeavour Energy throughout

FAQs
By ensuring your property is inspected by High Demand Electrical, you are taking a significant step towards securing its safety and enhancing its efficiency. Reach out today to learn more about how we can assist you in maintaining a safe and compliant electrical environment.
An Accredited Service Provider authorised to design new and altered network connections — drawings, single-line diagrams, protection settings, load calculations and the documentation the network needs to approve a project.
Issued by the network after assessing capacity, connection points and fault levels for your site. It sets the technical boundaries your designer must work within.
Level 3 designs the network solution. Level 1 physically constructs it. Holding both in-house removes handover risk between separate contractors.
Any new or altered network connection — a new commercial supply, subdivision, or substation — needs Level 3 design documentation before construction can proceed.
Yes. We hold Level 1, 2 and 3 ASP accreditation, so we can design, construct, commission and connect as one coordinated package.
Depends on project complexity and how quickly the network issues its Method of Supply document. Simple commercial connections turn around faster than multi-stage subdivisions or substation designs.
Testimonials
"Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.
When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.
