Security Fence Cost: 2026 UK Price Guide

Security fencing costs significantly more than standard garden fencing because of the materials used, post foundations required, and specialist installation. Whether you’re securing a commercial yard, industrial site, or domestic boundary against intrusion, costs in 2026 range from £40/m to over £200/m installed, depending on the system.

The most common types installed in the UK are steel palisade, welded mesh (358/V-mesh), and expanded metal or spike-top panel systems.

Security Fencing Types and Costs

Prices include posts, concrete foundations, and fitting but assume level ground with reasonable vehicle access.

What Drives the Cost

Height

Security fencing under 1.2 m is rarely effective as a deterrent. Most commercial installations start at 1.8 m. Each additional 0.3 m of height increases material cost by roughly 10–15%, plus slightly heavier posts.

Post Spacing and Foundations

Standard post spacing for palisade and mesh fencing is 2.5–3 m. Posts are typically set in concrete foundations, diameter and depth depend on fence height:

• 1.8 m fence: 450 mm diameter × 700 mm deep concrete pad
• 2.4 m fence: 450 mm diameter × 900 mm deep concrete pad
• 3 m fence: 600 mm diameter × 1.2 m deep concrete pad

Rocky ground, high water table, or made-up ground requiring deeper foundations increases cost.

Anti-Climb Features

• 358 welded mesh has 76.2 × 12.7 mm apertures, too small for fingers or toes, hence “anti-climb”
• Palisade D-post tops can be specified as flat, three-point, or round spike, spike-tops add approx £5–£10/m
• Rotating spike inserts or anti-climb paint can be added to any fence top: anti-climb paint (non-hardening) costs £8–£15 per tin covering ~4 m² and requires specific signage under the Occupiers’ Liability Act 1984

Ground Conditions

Rocky ground, sloping sites, or sites with underground services add £10–£40/m to groundworks. A site survey is advisable before quoting larger contracts.

Access and Mobilisation

For runs under 20 m, mobilisation costs (vehicle, tools, concrete delivery) can add £200–£500 as a fixed cost, increasing the effective per-metre rate substantially. For large sites (100 m+), per-metre rates fall.

Worked Example: Securing a Commercial Yard

Perimeter: 80 linear metres Specification: 2.4 m palisade with three-point spear tops, two vehicle gates

Gates

Security gates must be matched to the fencing in height and specification to avoid a weak point. Common options:

• Swing gates: cheaper, need clearance space; from £400 (pedestrian) to £2,000+ (double vehicle gate)
• Sliding gates: better for tight spaces; motor-operated from £1,500–£4,000 depending on weight and automation
• Automated barriers: for high-traffic vehicle management; from £3,000–£8,000 installed

Planning Permission

Domestic properties: Permitted development allows fences up to 1 m height adjacent to a highway, and 2 m elsewhere, without planning permission (England; slightly different rules apply in Wales and Scotland). Security fencing over 2 m in a residential garden requires planning permission. Conservation area or listed building constraints may apply at lower heights.¹

Commercial properties: Planning is generally required for commercial security fencing over 2 m or adjacent to a highway. Some light industrial areas have simplified processes, check with your local planning authority.

Anti-climb paint signage: The Occupiers’ Liability Act requires visible warning signs wherever anti-climb paint is applied; failure to display these means liability for injury shifts to the property owner.

Finding a Specialist Contractor

Security fencing installation is a specialist trade. Look for contractors who:

• Are members of the Fencing Contractors Association (FCA)
• Can supply a specification sheet and relevant certification (e.g., LPS 1175 for rated security systems)
• Provide concrete mix and foundation specifications in writing

For high-security or government projects, contractors may need to be pre-approved under framework agreements (e.g., Crown Commercial Service). Always get at least three quotes for any project over £5,000, and verify the contractor carries adequate public liability insurance (minimum £2 million for commercial work).
