How Much Does It Cost to Install a Generator Transfer Switch in Brisbane?
When Brisbane storms or blackouts hit, a backup generator is only as reliable as the switch that connects it. That’s where a generator transfer switch comes in, it safely switches your power from the grid to your generator during an outage.
If you’re wondering about the cost of transfer switch installation or whether you need an automatic transfer switch, here’s everything you need to know.
What Is a Generator Transfer Switch?
A generator transfer switch connects your main switchboard to your generator. When mains power fails, it diverts the electrical supply so your home or business can run safely on backup power — without messy extension leads or dangerous back-feeding.
There are two main types used across Queensland homes and businesses:
Manual Transfer Switches
Manually operated, ideal for smaller homes or rural properties where power can be restored by the owner.
- Lower installation cost
- Reliable and simple to operate
- Best suited to short, occasional outages
Automatic Transfer Switches (ATS)
Automatically detect a power outage and switch to generator power within seconds — ideal for medical facilities, aged care homes, retail spaces, or businesses that can’t afford downtime.
- Higher cost, but fully automatic
- Provides seamless transition and safety
- Meets commercial continuity standards
How Much Does It Cost to Install a Transfer Switch in Brisbane?
Installation costs depend on the switch type, power rating, and wiring complexity, but here’s a general guide:
| Type of Transfer Switch | Starting From (AUD) | Best For |
|---|---|---|
| Manual Transfer Switch | $795 – $1,500 | Homes & small offices |
| Automatic Transfer Switch (ATS) | $1,800 – $3,500+ | Businesses & continuous power setups |
| Generator + Transfer Switch Package | $3,000 – $6,000+ | Complete backup systems |
When You Might Need a Generator Transfer Switch
A professionally installed transfer switch is essential if you rely on:
- Medical or mobility equipment that must run 24/7
- Remote work setups or home offices requiring consistent power
- Cold storage or commercial refrigeration
- Rural properties with water pumps, irrigation, or electric fences
- Data or server systems that must stay online
Single-Phase vs. Three-Phase Transfer Switches
Most Brisbane homes run on single-phase power, suitable for basic backup setups.
However, if your property or business uses high-demand appliances or three-phase machinery, you’ll need a three-phase transfer switch to maintain even load distribution.
Our team at Precision Electrical & Air are licensed to install both single-phase and three-phase transfer switches, ensuring safe integration with your main switchboard.

Generator Transfer Switch FAQs
What does a generator transfer switch do?
A transfer switch safely connects your generator to your home’s electrical system. When mains power fails, it automatically or manually diverts electricity from the grid to your generator. This prevents dangerous back-feeding and keeps essential circuits—like lighting, refrigeration, or medical devices—powered during an outage.
How much does it cost to install a generator transfer switch in Brisbane?
Installation costs generally range from $700–$1,500 for manual systems and $1,800–$3,500 for automatic transfer switches (ATS). The total cost depends on your switchboard condition, wiring complexity, and whether you need single-phase or three-phase integration. We always provide transparent quotes before work begins.
What’s the difference between a manual and an automatic transfer switch?
Manual Transfer Switch – You switch the power source yourself during an outage. It’s reliable, affordable, and ideal for smaller homes or rural properties.
Automatic Transfer Switch (ATS) – Detects an outage instantly and switches to generator power automatically. It’s perfect for commercial premises, aged-care facilities, and any property where downtime isn’t acceptable.
Do I need a licensed electrician to install a transfer switch?
Yes. Under Queensland’s Electrical Safety Act 2002 and AS/NZS 3000:2018 Wiring Rules, only a licensed electrician can legally install or connect a generator transfer switch. DIY installations are unsafe, non-compliant, and can void insurance or warranty coverage.
Can I connect my generator directly to a power point instead?
No. Plugging a generator directly into a household outlet is extremely dangerous and illegal in Queensland. It can back-feed electricity into the grid, putting you and electrical workers at risk. A transfer switch ensures safe isolation and proper load management.
Does a transfer switch work with solar or battery systems?
Yes — but it must be integrated correctly. Our electricians assess how your generator, solar, and battery system interact to ensure they don’t conflict. We can install a compatible three-phase or hybrid setup that prioritises your solar first and automatically switches to generator power if needed.
How long does a transfer switch installation take?
Most installations take half a day to one full day, depending on the type of switch and existing electrical layout. We’ll test the system, issue compliance certification, and ensure everything operates safely before we leave.
How do I know if I need a generator transfer switch?
If you rely on medical devices, refrigeration, home offices, or farm equipment, a transfer switch is essential. It’s also recommended for properties in rural or storm-prone parts of Brisbane that experience regular outages.
