Install an electric gate.

However, installing automated gates is a complex engineering task that involves groundworks, precision metalwork or carpentry, and specialist electrical engineering. Ensuring your system is safe, reliable, and compliant with UK safety standards is essential to protect both your family and your liability as a property owner.

What Does the Work Involve?

• Site Survey: Assessing ground levels, driveway width, and drainage to determine the best gate type (swing or sliding).
• Groundworks: Excavating for gate posts, installing underground cable conduits, and pouring concrete foundations.
• Gate Hanging: Mounting the gate leaves or track with precision to ensure smooth movement and minimal strain on motors.
• Automation Fitting: Installing the motors (underground or surface-mounted), control board, and mechanical stops.
• Safety Devices: Fitting infrared photocells, safety edges (pressure strips), and induction loops to prevent the gate from closing on obstacles.
• Electrical Connection: Running a dedicated armoured cable (SWA) from the consumer unit to the gate control panel.
• Commissioning: Programming remote controls, intercoms, and conducting force testing to ensure the gate stops safely upon impact.

Typical Costs

The cost of electric gate installation varies significantly based on the material of the gates (wood, steel, or aluminium) and whether you choose a swing or sliding mechanism. Sliding gates often require more expensive track installation and groundworks, while underground swing motors are more aesthetic but pricier to install.

Note: Prices include VAT at 20%. Factors such as the distance from your house to the gates and the need for new brick pillars can add £2,000 or more to the final bill.

How Long Does It Take?

• Site Preparation & Groundworks: 1–2 days. This includes digging foundations and laying cable ducts.
• Concrete Curing: 3–5 days. Foundations must be fully set before the weight of the gates is applied.
• Installation & Wiring: 1–2 days. Hanging the gates and connecting the electrical components.
• Testing & Handover: 2–4 hours. Final safety checks, force testing, and explaining the system to the homeowner.

DIY or Professional?

Electric gate installation is not recommended as a DIY project. Under UK law, an automated gate is classified as a "machine," and the person who installs it is legally responsible for its safety and compliance.

Errors in installation can lead to serious injury or even fatalities if safety sensors fail or motors are too powerful. Furthermore, all new electrical circuits must be installed and certified by a Part P registered electrician to comply with UK Building Regulations.

Choosing the Right Tradesperson

• Accreditations: Look for installers certified by Gate Safe or the DHF (Door & Hardware Federation).
• Electrical Qualification: Ensure they are qualified to work on mains electrics or work with a certified electrician.
• Portfolio: Ask to see photos of previous local installations to check the quality of their finish.
• Questions to Ask:
  • Will you provide a Force Test Certificate upon completion?
  • What happens if there is a power cut — is there a manual override?
  • Is the motor rated for the weight and wind-loading of these specific gates?
  • Do you offer an annual maintenance contract?

UK Regulations

• Machinery Directive: All automated gates must comply with BS EN 12453, ensuring they have sufficient safety features to prevent crushing.
• Part P (Building Regs): Electrical supply to the gates must be installed by a competent person and notified to local building control.
• Planning Permission: Generally not needed if the gate is under 1 metre high next to a highway, or 2 metres elsewhere. Always check with your local council first.
• Documentation: You should receive a CE/UKCA Marking, a Declaration of Conformity, and a safety logbook.

Common Problems

• Inadequate Drainage: Underground motors sitting in water will fail prematurely; proper soakaways are essential.
• Wind Loading: Solid "close-boarded" gates act like sails; in high winds, underpowered motors may burn out or fail to close.
• Pest Damage: Slugs and spiders often enter control boxes, causing short circuits on the PCB.
• Lack of Maintenance: Hinges and pivot points need regular greasing to prevent the motor from overworking.
