When I started looking into automating my own driveway gate, the first thing I asked was simple: how much is an electric gate motor installation? I expected a straight answer, maybe a price list online, something like that. Instead, what I found were wide-ranging quotes that didn’t seem to match up. One installer said $1,800. Another said $4,000. And neither explained why the difference was so big.
If you’ve been through the same confusion, you’re not alone. The price isn’t random; it comes down to the type of motor, the style and condition of your gate, and the complexity of the work involved. Once you understand those pieces, you’ll know exactly what to expect when you ask for quotes.
So, How Much Is an Electric Gate Motor Installation on Average?
The truth is that most homeowners in Australia end up paying somewhere between $1,500 and $4,500 all up. That figure usually includes:
-
The motor and control kit.
-
Professional installation.
-
At least one set of remotes.
-
Basic safety gear, like infrared sensors.
Of course, if your setup is straightforward, you’ll be near the lower end. If you want extra features or have a complicated site, the figure climbs.
What Affects the Price of Electric Gate Motor Installation?
Let’s break down the main factors that push the cost up or down.
1. Type of Gate
Sliding gates are generally cheaper to automate because one motor pulls the gate along a track. Swing gates often require two motors, one for each side, which means double the hardware and double the labour.
2. Motor Style
-
AC motors: Solid, durable, and ideal for heavier gates.
-
DC motors: Quieter, smoother, and usually include battery backup. Popular for residential use.
-
Hydraulic motors: Built for very large or frequently used gates, such as commercial properties. These are the most expensive to buy and install.
3. Power Supply
If electricity already runs to the gate, you’re in luck. If not, an electrician will need to dig trenches and lay cables, which can add $500–$1,500 depending on distance and soil conditions.
4. Gate Condition
Motors only work well if the gate already moves smoothly. If your gate drags on the ground, is misaligned, or has rusty hinges, installers will often charge extra to fix it before attaching a motor.
5. Optional Features
Safety beams, Wi-Fi controllers, intercoms, and keypad entry systems all add convenience and extra costs.
Motor Costs Before Installation
Knowing motor prices helps you understand where your money goes.
-
Budget kits: $500–$900.
-
Mid-range residential motors: $1,000–$1,800.
-
Premium or hydraulic systems: $2,000–$4,000+.
If your installer quotes $3,000 total, you can usually assume about half is the motor itself and the rest is labour, wiring, and accessories.
How Much Is an Electric Gate Motor Installation for Sliding Gates?
Sliding gates are the simpler option.
-
Basic installation with one motor: $1,500–$2,200.
-
Mid-range setup with safety sensors and multiple remotes: $2,000–$3,000.
-
Heavy-duty sliding gates: $3,500 or more.
If the track is smooth and level, you’ll pay less. If it needs repair or replacement, that will push you up the scale.
How Much Is Electric Gate Motor Installation for Swing Gates?
Swing gates usually cost more.
-
Single swing gate with one motor: $1,700–$2,500.
-
Double swing gate with two motors: $2,500–$4,000.
-
Underground motors for a cleaner look: $4,000–$6,000+.
Underground motors hide everything from sight, but they take more digging and waterproofing, which explains the price jump.
DIY vs Professional Installation
You’ll find DIY motor kits online, and yes, some people do install them. But before you grab your tools, keep this in mind:
-
A licensed electrician is still needed to handle wiring.
-
Incorrect alignment can wear out a motor in months.
-
Many warranties only apply if a professional installer does the work.
So while DIY might save money upfront, professional installation often saves you stress and replacement costs later.
Ongoing Costs After Installation.
When asking how much an electric gate motor installation costs, don’t forget about what comes after the motor is fitted.
-
Annual servicing: $150–$250 to keep everything running smoothly.
-
Repairs: Sensors, circuit boards, or replacement remotes can cost $100–$400.
-
Electricity use: Very low, usually less than leaving a light bulb on.
If you keep up with maintenance, a good motor should last 10 to 15 years, sometimes longer.
How to Get the Best Value.
Here are some simple but effective ways to make sure you don’t overpay:
-
Compare quotes. Always get at least three.
-
Check what’s included. Some quotes sneakily leave out sensors or remotes.
-
Look at warranties. A motor with a 5-year warranty is often a better value than a cheaper one with only 12 months of cover.
-
Choose reliable installers. A poorly installed motor won’t last long.
Real-Life Examples of Costs
-
A family with a single sliding gate and power already at the fence paid $1,800 total.
-
Another household with a double swing gate, trenching for power, and keypad entry ended up at $4,200.
-
A business near town with a heavy sliding gate and a hydraulic motor spent more than $6,000.
This is why it’s hard to give one answer to how much an electric gate motor installation costs; it really depends on the details.
Final Thoughts: How Much Is Electric Gate Motor Installation Really?
So, back to the question. How much is an electric gate motor installation? For most homes, you’ll pay between $1,500 and $4,500. Sliding gates usually cost less, while swing gates, especially double or underground systems, cost more.
It may feel like a big spend, but the payoff is convenience and security. No more hopping out of the car in the rain to open the gate. No more leaving it unlocked because it’s too much effort. Once you’ve had an electric gate motor, you won’t want to go back.
The key is to match the motor to your gate, choose a reliable installer, and budget a little for yearly servicing. Do that, and your system should last a decade or more without major drama.
