An electric gate isn't just a motor. It's a small system of parts that all have to work together – and when one is wrong, the whole gate suffers. Here's what goes into a typical setup, so you know what you're paying for.
The parts of the system
- The motors. One per gate leaf for swing gates, or one for a sliding gate. Overground, underground, hydraulic or sliding. See comparing gate motor types.
- The control board. The brain of the system, usually in a weatherproof box near the gate. It tells the motors what to do, reads the safety devices and handles the remotes and other inputs.
- Safety devices. Photocells, safety edges and other sensors that stop the gate if something's in the way. See photocells, safety edges and sensors explained.
- Access control. Remotes, keypads, intercoms, fobs and app control. See access control.
- Warning light. A flashing lamp so people know the gate is about to move.
- Locks. Built into the motor, or extra electric locks and maglocks.
- Power. A dedicated supply to the gate, done to BS 7671, plus optional battery backup. See power supply for electric gates.
Matching the system to the gate
The right system depends on:
- the gate's weight, width and height, and whether it's solid (wind load matters)
- how often it's used – a home gate might open ten times a day, a car park gate hundreds
- the site – slope, space behind the gate, ground conditions and power
- who uses it – family, staff, public, children
An undersized motor will struggle and wear out quickly. An oversized one costs more than it needs to. Getting the match right is a big part of my job.
The brands I install
For new installations I use DEA System on domestic and commercial gates, and Fadini hydraulics for heavy-duty gates. Using the same trusted brands means I know the kit inside out and can get parts quickly. See why I use DEA System and Fadini.
Got an older system?
If your existing system is tired, unreliable or missing safety devices, I can often upgrade the parts that need it rather than replacing everything. See upgrading old gate motors and control boards.

Questions people ask me
What's the most important part of a gate automation system?
They all matter, but a motor that's properly sized for the gate, and safety devices that are set up correctly, make the biggest difference.
Can I mix brands?
Some accessories work across brands, but the motors and control board should be matched. I'll make sure everything is compatible.
How long does a gate automation system last?
It depends on the quality, how much it's used and how well it's serviced. Good kit that's serviced regularly lasts many years.
