What Are the Electrical Rules for Shopfront and Signage Installations in Sydney?

What are the electrical rules for shopfront and signage installations in Sydney? A sign company can design, fabricate and physically mount an illuminated sign, but connecting it to power is electrical work that has to be done by a licensed electrician on its own dedicated, isolatable circuit. A new circuit also needs a Certificate of Compliance for Electrical Work once it is finished, and whether the tenant or the landlord pays for it usually comes down to what the lease actually says about fit out works.

1. What actually counts as electrical work on a shopfront

A shopfront or signage project usually involves two very different trades. The sign company handles design, fabrication, LED modules and the physical mounting of the cabinet or lettering to the building. Everything from that point back, the circuit it plugs into, the isolator, the cable run and the connection back to the shop's switchboard, is electrical work under AS/NZS 3000 and has to be carried out by a licensed electrician. Plenty of signage problems we are called out to fix started with a sign installer running a flexible cord straight into an existing general power circuit rather than getting a dedicated circuit installed properly.

2. Why illuminated signage needs its own dedicated, isolatable circuit

AS/NZS 3000 Clause 2.3.2.2 sets out the general requirements for isolation devices, including that a device must clearly indicate whether it is open or closed, must be capable of being secured in the open position, and must disconnect all active conductors. A dedicated isolator next to a sign or shopfront lighting circuit means a tenant, a cleaner, or a tradesperson can switch it off safely for bulb or LED module replacement without having to kill power to the entire shop. For a busy retail tenancy, especially one trading extended hours, that separation is not just a compliance box to tick, it genuinely makes ongoing maintenance easier.

3. Who does what: signwriter versus licensed electrician

A sign company's licence, where they hold one, generally covers their own trade: design, fabrication, structural fixing and sometimes low voltage LED driver wiring within the sign cabinet itself. The mains connection back to the switchboard, any new circuit breaker, the isolator, and the safety switch protection all sit with a licensed electrician. If you are engaging a sign company for shopfront work, it is worth confirming upfront who is arranging the electrical connection, since this is one of the most common gaps between quotes, with each side assuming the other has it covered.

4. Landlord or tenant: who actually pays

This comes down to the lease, not a general rule. Most commercial leases treat signage and shopfront branding as part of the tenant's fit out, meaning the tenant pays for the circuit, isolator and connection as part of setting up the shop. Base building power, the main switchboard and the supply up to the tenancy's own board, usually remains the landlord's responsibility. Make good clauses also matter here: some leases require signage circuits to be removed and the tenancy returned to base condition at the end of the lease, which is worth checking before you spend money on a permanent looking installation.

5. Getting the Certificate of Compliance for Electrical Work right

Any new or altered circuit, including a signage circuit, needs a Certificate of Compliance for Electrical Work once the job is finished. Our guide to the Certificate of Compliance for Electrical Work covers what this document actually certifies and why it matters if the tenancy is ever sold, re leased or inspected by council. For a retail fit out on a deadline, getting this paperwork sorted at the same time as the physical work avoids a scramble later when a landlord or council asks for proof the signage circuit was done properly.

6. What we commonly find on older Sydney shopfronts

Retrofitting an inspection into an older shopfront regularly turns up the same issues: signage powered from a shared general power circuit rather than its own dedicated one, an extension lead or power board run externally and exposed to weather, no accessible isolator for maintenance, and in some cases cabling that predates current safety switch requirements entirely. None of this is unusual for a shop that has changed hands or had signage swapped out multiple times over the years without anyone reviewing the electrical side properly.

Why it's sometimes Level 2 ASP work

Most shopfront and signage circuits sit entirely within the tenancy's own wiring and only need a standard licensed electrician. Where a shopfront upgrade is paired with a larger fit out that increases the tenancy's overall demand, such as new refrigeration or air conditioning alongside the signage, it can trigger the need for a Level 2 ASP to review or upgrade the connection itself, which High Demand Electrical is accredited to carry out directly.
