Look up from Miller Street and you’ll see glass towers, rooftop terraces and harbour views. What you won’t see is what keeps them running: the access cards at the lift, the cameras over the loading dock, the switchboard behind a plant room door. When those work, nobody notices. When they don’t, everyone does.
CGF looks after that hidden side of North Sydney. We’re licensed electricians who specialise in security systems for corporate suites, apartment towers and older terraces across the Lower North Shore. That means your security is wired properly and your electrical work comes from the same team.
Office security here can’t work in isolation. It has to fit with building management, reception, cleaning crews and multiple tenants sharing a floor. We design systems that slot into your building instead of fighting it.
Give each staff member access to the zones they need, nothing more. Clients sign in at reception, cleaners get after-hours access to set floors only, and every entry is logged. For law firms, accountants and financial services handling confidential files, restricted zones and audit trails aren’t a nice-to-have. Your clients and insurers expect them.
On shared floors, we secure your suite entry while keeping common areas accessible. We also connect with building access cards where your building allows it, so staff carry one card.
We cover suite entries, reception and server rooms, with cameras positioned to avoid screens and client documents. Our CCTV systems run on your network with remote viewing, analytics and footage you can actually use if something happens.
Cafés, lunch bars and retail: Ground-floor shops on Miller and Berry Street go from quiet to slammed in minutes at lunch. Our cameras cover tills, high-value stock, entries and back-of-house, including storage and loading docks shared with other tenants. Footage is clear enough for insurance and police.
Medical, dental and allied health: Cameras cover reception and entries, never consult rooms or screens with patient information. Access control locks down medication storage and records with a full audit trail, and alarm zones let you secure part of a suite while the rest stays open. Practitioners on different schedules each get their own credentials.
Salons and studios: Access control suits rental-chair setups, with after-hours alarms protecting equipment and stock.
Childcare centres: Many North Sydney centres sit in converted offices across multiple floors. We design around that, with secure entry and visitor logging, cameras over indoor and rooftop play areas, and alarm zoning that supports licensing. We also provide documentation to help with approvals.
Residents in North Sydney’s towers expect a lot, and outdated intercoms or patchy car park coverage show fast. We upgrade buildings to video intercom systems with phone answering and concierge integration, add access control to car parks, lifts and parcel rooms, and cover common areas with CCTV.
For mixed-use towers, we keep retail, office and residential security completely separate, with one building and three zones. We work directly with your strata or building manager on approvals.
Many established North Sydney homes and terraces still run on old switchboards that weren’t built for modern loads. Harbour moisture and windy days expose weak spots fast, showing up as lights flickering in damp weather, safety switches tripping or loose power points. Our residential electricians find the cause, whether that’s an overloaded circuit or wiring behind the walls, and fix it properly. We upgrade switchboards with RCD safety switches and enough capacity for how you live now.
We install chargers in apartment basements, double garages, shared car parks and renovated homes. We check your load first, upgrade wiring where needed, and set it up to run safely every day. Want backup power for storm season or lower bills? A home battery system stores cheap or solar power for when you need it. Older homes may need an electrical upgrade first, and we handle that too.
Apartments and closely built homes make fire safety critical. We install photoelectric, interconnected alarms, replace expired units, and test annually to NSW standards.
Offices, restaurants, gyms and professional suites rely on power that doesn’t drop out. Our commercial electricians handle fit-outs, lighting upgrades, switchboard and safety work, fault finding and routine maintenance. We work after hours if needed, so your team keeps working.
We cover North Sydney, Milsons Point, Kirribilli, Lavender Bay, McMahons Point, Waverton, Wollstonecraft, Crows Nest, Neutral Bay, Cammeray, St Leonards and the rest of our Sydney service areas.

Usually, yes, inside your leased space. Internal cameras, suite access control and alarms are generally within tenant rights. Cameras in lobbies, lifts or other common areas need building management approval. We liaise with your building manager so your system fits their rules and doesn’t clash with existing coverage.
Tailgating happens when someone follows a staff member through a secure door. Door-held-open alarms, camera coverage at the entry and card readers that log every swipe are the usual fixes. For high-traffic suites, a speed gate or interlocking doors allow one person per credential.
Yes. We put access control on your suite entry and any internal restricted rooms, while lifts, kitchens and bathrooms stay open to everyone. Your staff use credentials only for your space, and other tenants can’t get in.
Many enterprise access control platforms can sync with HR systems or directory services, so access is granted when someone starts and removed when they leave. Whether it works for you depends on the platform and your IT setup, and we’ll scope it with your IT team.
Controlled entry so only authorised adults get in, especially from shared lifts and stairwells. You also need visitor logging, cameras over indoor and any rooftop or terrace play areas, and alarm zoning that doesn’t block emergency exits. We design around the building and provide documentation for licensing.
Yes. Access-controlled boom gates or roller doors, resident credentials, and cameras at the car park entry that capture number plates make it clear who’s coming and going. Unregistered vehicles stand out, and the footage backs up any action your strata takes.
Usually there’s moisture getting into an outdoor fitting or junction box, or a loose connection that moves in the wind. Harbour moisture makes this more common in older homes. It’s a fault, not just a quirk, so get it checked before it becomes a safety issue.
Yes, with strata approval. We assess the building’s supply, recommend an individual or shared charger setup, and add load management so several cars can charge without overloading the building. We also prepare the technical details your committee needs.
Many do, especially if they still have ceramic fuses, no safety switches or original wiring. We inspect first and only recommend what’s needed. Sometimes that’s a full rewire, but often a switchboard upgrade and a few new circuits are enough.
Yes. Most commercial work in North Sydney is done early morning, evenings or weekends to suit building access rules and avoid disrupting staff. We coordinate loading dock bookings and lift access with your building manager.
