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
| Type | Height Options | Cost Per Linear Metre (installed) | Typical Use |
|---|---|---|---|
| Steel palisade (D-post, W-section) | 1.2 m–3 m | £60–£120/m | Commercial premises, car parks |
| Welded mesh (358 anti-climb) | 1.8 m–3 m | £50–£100/m | Schools, depots, yards |
| V-mesh / Rebound mesh | 1.5 m–3 m | £45–£85/m | Industrial, residential |
| Expanded metal mesh | 1.8 m–2.4 m | £60–£110/m | Utilities, substations |
| Steel spike-top panel | 0.9 m–2 m | £80–£150/m | Residential, heritage boundaries |
| Electric fence (standalone) | 1–2 m | £100–£250/m | High-risk commercial, MoD |
| High-security / LPS 1175 certified | 2 m–3 m | £150–£300+/m | Critical infrastructure |
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
| Item | Cost |
|---|---|
| 80 m palisade (supplied and installed) | £7,200 (£90/m) |
| Double vehicle gate, 4 m wide | £1,200–£2,000 |
| Pedestrian gate | £400–£700 |
| Groundworks (level site) | Included |
| Total | ~£9,000–£10,000 |
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.
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).
