When it comes to installing automatic gates, the quality of the installation matters just as much as the gate itself. A premium gate paired with a rushed install will always disappoint, while a properly engineered system delivers reliable security and convenience for decades. The process involves far more than simply hanging a gate and plugging in a motor — it’s a sequence of carefully managed stages, each of which determines how well your system performs over its lifetime.
As Hertfordshire’s automatic gate specialists, we’ve refined our installation process to deliver consistent, compliant results across residential and commercial sites. Here’s exactly what to expect.
What’s Involved in Installing Automatic Gates?
A professional automatic gate installation moves through five distinct stages: site survey, design and specification, groundworks and power supply, gate and motor installation, and commissioning. Each stage builds on the last, and skipping or rushing any of them is the most common cause of long-term problems. The full process typically spans two to four weeks from initial enquiry to handover, depending on site complexity.
Stage 1 – The Site Survey
Every reliable installation starts with a thorough on-site assessment. Our engineers measure the entrance width, check ground gradients, inspect existing piers or fence posts, and identify the nearest power supply. We also discuss how you intend to use the gates day to day — frequency of use, vehicle types, pedestrian access, and any access control requirements.
Phone or email quotes for automatic gate installation are notoriously unreliable because they can’t account for site conditions. A free site survey eliminates the guesswork and ensures the quote you receive reflects the actual work involved.
Stage 2 – Design & Specification
With the survey complete, we move into design. The two most important decisions are gate type and motor type. Swing gates suit most properties with sufficient driveway depth, while sliding gates are ideal for narrow entrances or sloped approaches. Cantilever systems are reserved for sites where ground tracks aren’t viable.
Motor selection depends on the weight of the gate, frequency of use, and the aesthetic you want. Above-ground motors are quicker to install and easier to service, while underground motors offer a cleaner finish for properties where appearance is a priority. Our guide on how automatic gates work explains the mechanics in more detail.
Stage 3 – Groundworks & Power Supply
This is the stage that catches most homeowners by surprise. Automatic gates need solid foundations — typically reinforced concrete pads at least 600mm deep — to ensure the posts remain rigid under the daily loads of motor operation. Sliding gates require a level concrete track or a beam guide system, which often involves additional excavation.
Power supply is equally important. The wiring requirements for electric gates include a dedicated, weatherproof cable run from your consumer unit to the gate location, ducted underground at the correct depth and protected from damage. We handle all electrical work to current Part P regulations, including any earthing, RCD protection, and ducting for low-voltage control cables to intercoms or keypads.
Stage 4 – Gate & Motor Installation
Once the groundworks have cured, the gates and motors are fitted. This is the stage most people picture when they think of installing automatic gates, but it’s actually one of the shorter phases — typically completed in one to two days for a standard residential setup.
We hang the gates, install the motors, mount the control panel, and fit all the safety equipment: photocells, safety edges, and warning lights as required. Every installation we complete is force-tested to BS EN 12453, the UK safety standard for powered gates. This isn’t optional — it’s a legal requirement, and any installer who skips it is exposing you to serious liability. We also wire in any chosen access control, such as video and audio intercom systems, keypads, or smartphone-controlled receivers.
Stage 5 – Commissioning & Sign-Off
The final stage is where the system is properly tested and handed over. We run through every operating scenario — opening, closing, obstruction detection, manual override, and remote control programming — to confirm everything performs to specification. You’ll receive full documentation, including the EN 13241 declaration of conformity, force test results, and your warranty paperwork.
We also walk you through routine care and demonstrate how to operate the gates safely. Regular servicing keeps the system running reliably, and should anything go wrong further down the line, our electric gate repair team is on hand across Hertfordshire.
Why Choose a Specialist for Installing Automatic Gates?
Automatic gates are a substantial investment, and getting the installation right protects that investment for years to come. Generic builders or general electricians often lack the specialist knowledge needed to deliver a fully compliant, properly engineered system — and the consequences usually surface within months of completion. Our guide on common electric gate installation mistakes explores the pitfalls in detail.
At Total Automation, every installation is delivered in-house by our trained engineers, with full safety testing, compliance documentation, and ongoing support as standard. Get in touch today for a free site survey and a transparent quote tailored to your property.
