Install a metal gate.

Whether you are looking for a decorative wrought iron pedestrian gate or automated steel driveway gates, a professional installation ensures the structure is perfectly aligned and securely anchored. This guide covers everything from fabrication processes to the latest UK pricing for 2025.

What Does the Work Involve?

• Site Survey: Precise measurements of the opening, checking for ground levels and potential obstructions.
• Design and Fabrication: Most metal gates are custom-made off-site in a workshop using steel or iron, then galvanised or powder-coated.
• Post Installation: Digging footings and setting heavy-duty metal posts in concrete to support the weight of the gate.
• Hanging and Alignment: Mounting the gate onto hinges and ensuring it swings freely and latches correctly.
• Hardware Fitting: Installing locks, drop bolts, decorative finials, or automation motors if required.
• Finishing Touches: Applying touch-up paint to any welded joints or drill points to prevent corrosion.

Typical Costs

Prices for metal gates vary significantly based on the complexity of the design and the weight of the materials used. Custom-fabricated wrought iron is generally more expensive than off-the-shelf tubular steel options.

Material costs are the primary driver of the final price, specifically the choice between powder-coated steel and hot-dipped galvanised finishes. Bespoke scrollwork and heavy-gauge iron will push quotes toward the higher end of the spectrum.

How Long Does It Take?

• Survey and Design: 1–2 hours for the initial site visit and measurements.
• Fabrication: 2–4 weeks (off-site) depending on the workshop's current lead times.
• Standard Installation: 4–6 hours for a single pedestrian gate including post-setting.
• Driveway Gate Installation: 1–2 days, allowing time for concrete to set and precise hinge adjustment.
• Automation Setup: An additional 1 day for wiring, motor mounting, and safety testing.

DIY or Professional?

While a very confident DIYer might manage a lightweight, pre-made garden gate, professional installation is strongly recommended for metal gates. These units are incredibly heavy; if a post is not set deep enough or the concrete mix is weak, the gate will sag and fail within months.

Professional installers have the specialised welding equipment and heavy-duty lifting gear required to ensure the gate is perfectly level and safe for years of use.

Furthermore, if you are installing automated gates, you must use a professional. These systems fall under "Machinery Directive" regulations and require specific safety sensors to prevent injury or entrapment.

Choosing the Right Tradesperson

• Look for members of the Gate Safe or DHF (Door & Hardware Federation), especially for automated systems.
• Check if they offer a galvanising service as standard; this is essential for preventing rust in the UK climate.
• Red Flag: A contractor who doesn't ask about the ground conditions or drainage before quoting for posts.
• Question: "Is the metal hot-dipped galvanised before being powder-coated?"
• Question: "What depth of concrete footings do you recommend for these specific gate weights?"
• Question: "Do you provide a warranty against rust and structural failure?"

UK Regulations

• Planning Permission: Generally required if the gate is over 1 metre high next to a highway, or over 2 metres elsewhere.
• Listed Buildings: You will almost certainly need Listed Building Consent for any new gate installation.
• Part P (Electrical Safety): If installing automated gates, all electrical work must comply with Part P building regs.
• Safety Standards: Automated gates must be CE/UKCA marked and include force-testing documentation upon completion.

Common Problems

• Post Sagging: Occurs when footings are too shallow for the weight of the metal; ensure posts are set at least 600mm-900mm deep.
• Rust Spots: Common in non-galvanised steel; always opt for galvanisation to avoid repainting every two years.
• Hinge Binding: Usually caused by ground movement or poor initial alignment; adjustable hinges can help mitigate this.
• Automation Failure: Often due to poor drainage around motor pits or pests nesting in the control box.
