Electrical Engineer Sign-Off in Melbourne: What RPEV Means for Your Project
If you're delivering an electrical or building services project in Victoria, the engineering behind it now has to be signed off by a Registered Professional Engineer of Victoria (RPEV). Since electrical engineering became a mandatory registration area in mid-2023, this isn't optional — it's a legal requirement, and for building work there's an extra layer that catches a lot of people out.
This article explains what RPEV registration actually is, when you legally need it for electrical and building services work in Victoria, and the building endorsement requirement that specifically affects construction projects.
How Victoria's scheme works
Victoria introduced mandatory engineer registration under the Professional Engineers Registration Act 2017 (Vic). It's a co-regulatory model: an approved assessment entity (such as Engineers Australia, IPWEA Victoria or APEA) assesses an engineer's qualifications, experience and competency, and the Business Licensing Authority (BLA) then grants registration. Consumer Affairs Victoria oversees the public-facing side.
Registration is now mandatory across five areas of engineering — civil, structural, electrical, mechanical and fire safety. For electrical engineering specifically, registration became mandatory on 1 June 2023. In practice that means anyone providing electrical professional engineering services in or for Victoria must be a registered professional engineer in the electrical area, or work under the direct supervision of one.
The Act also protects the title itself: it's an offence for an unregistered person to call themselves a "professional engineer." So registration isn't just about who can sign — it governs who can hold themselves out as a professional engineer at all.
What counts as a "professional engineering service"?
Under the Act, a professional engineering service is any service that requires engineering judgement, knowledge and skill to deliver a fit-for-purpose outcome. If genuine engineering judgement is being applied, RPEV registration is required.
As in Queensland, there are two key exemptions:
Work carried out under the direct supervision of a registered professional engineer who takes responsibility for it, and
Services provided only in accordance with a prescriptive standard — typically a repetitive engineering activity where no real judgement is exercised.
The trap is the same one engineers fall into elsewhere: assuming that "designing to a standard" automatically means the prescriptive-standard exemption applies. It often doesn't. If applying the standard requires interpretation, calculation or judgement — which most real electrical and lighting design does — the work is a professional engineering service and needs an RPEV behind it.
For typical electrical and building services scope, work that generally requires RPEV sign-off includes:
Electrical distribution and switchboard design with load, fault-level and protection calculations
Power systems studies (load flow, short circuit, arc flash, protection coordination)
Lighting design requiring photometric calculation and standards interpretation (for example car parks, roadways and sports fields modelled in AGi32 against AS/NZS 1158, AS 4282 and AS 2560)
Solar PV and grid-connection design
EV charging infrastructure and supply upgrades
Any design involving genuine engineering decisions rather than a fixed procedure
The building endorsement — the part that matters most for construction
Here's the requirement that's specific to building work and easy to miss. An electrical engineer who intends to provide professional engineering services in the building industry must do two things: be registered in the area of electrical engineering, and hold a building endorsement on that registration.
For building services electrical work — lighting systems, control systems, security and communications, power for vertical transport, HVAC and fire detection within a building — the building endorsement is what makes the registration valid for that context. An electrical RPEV without building endorsement is not the right person to sign off building industry electrical work.
So when you engage an engineer for a Victorian building project, it's not enough to confirm they hold RPEV in electrical — you also need to confirm the building endorsement is in place. This is the single most common gap on building projects.
Interstate firms working on Victorian projects
Like Queensland, Victoria's scheme reaches beyond the state border. Engineers must be registered to provide professional engineering services both within Victoria and outside Victoria where the services are intended for Victoria.
That means a consultancy in Sydney, Brisbane or anywhere else preparing electrical design or a lighting package for a Melbourne project is captured by the Act exactly as a local firm would be — the work needs to be done by, or directly supervised by, a registered professional engineer in the electrical area. Interstate practices commonly partner with a Victorian-registered engineer for compliant sign-off so they can keep the project.
How to verify an RPEV before you engage them
Consumer Affairs Victoria maintains a public register of professional engineers registered to work in Victoria. Before relying on someone's sign-off, confirm that:
Their registration is current
They are registered in the electrical area of engineering
For building projects, they hold the building endorsement
The scope they're signing matches the work they've genuinely engineered
It's a quick check, and on a building project the endorsement detail is the one worth confirming every time.
Getting your Melbourne project signed off
The cleanest approach is to bring a registered electrical engineer in during design rather than at the certification stage, so calculations, documentation and standards compliance are right from the outset and the sign-off reflects work that's actually been engineered.
If you're an architect, builder or contractor who needs RPEV electrical and lighting sign-off for a Victorian project, I provide certified electrical design, AGi32 lighting packages and power systems studies with current RPEV registration — including white-label support where you keep the client relationship and I provide the compliant engineering behind it.
