Retractable Bollards UK: Rising, Automatic & Manual Options

Retractable bollards — also known as rising bollards or telescopic bollards — offer the best of both worlds: definitive vehicle exclusion when raised, and unrestricted vehicle access when lowered. This guide covers everything you need to know about choosing retractable bollards for UK applications.

Types of Retractable Bollard

Manual Retractable Bollards

Raised and lowered by hand, typically using a key or padlock mechanism. The bollard retracts into a ground sleeve that sits flush when lowered. No power supply required — making them ideal for locations where electrical installation isn't practical. Cost-effective option for low-frequency access requirements.

Hydraulic Rising Bollards

Powered by a hydraulic system, these bollards raise and lower at the push of a button. Cycle time is typically 3–5 seconds. Can be linked to access control systems, intercoms, ANPR cameras and remote fobs. The most robust option for high-traffic access control points.

Electromechanical Rising Bollards

Motor-driven bollards that are quieter and lower maintenance than hydraulic systems. Rise time 4–8 seconds. Suitable for pedestrianised zones, car parks and controlled access roads. Can be integrated with traffic light systems and vehicle detectors.

Telescopic/Folding Bollards

Compress into themselves or fold flat rather than retracting into the ground. No excavation required for the bollard body — only an anchor plate. Popular for retrofit installations where deep excavation is impractical.

Key Specification Factors

• Vehicle rating: Standard models deter casual incursion; security-rated models resist deliberate attack
• Rise height: Typically 600–1,000mm above ground
• Diameter: 115mm–220mm depending on security requirement
• Cycle frequency: Some models rated for 50 cycles/day, others 500+
• Fail-safe position: Fail-up (secure) or fail-down (open) — critical for emergency access
• Traffic light integration: Required for public road installations

Common Applications

• Pedestrianised town centre access control
• Car park entrance management
• Delivery time-restricted zones
• Shared surfaces requiring vehicle exclusion at certain times
• Building access control alongside ANPR

Installation Requirements

Rising bollards require a foundation chamber (typically 600–1,000mm deep and 350–500mm diameter) for the hydraulic/electrical mechanism. Hydraulic models require a power supply; pneumatic models may require a compressed air feed. Always check for underground services before excavation.

FAQ: Retractable Bollards UK

How much do retractable bollards cost?

Manual retractable bollards start from around £200–£400 each. Automatic hydraulic rising bollards typically cost £2,000–£8,000 per bollard including the mechanism, plus installation costs of £500–£2,000 depending on ground conditions.

How long does a retractable bollard take to rise?

Hydraulic bollards typically cycle in 3–5 seconds. Electromechanical models take 4–8 seconds. Manual bollards are raised as quickly as the operator can turn the key — typically 5–10 seconds.

Can retractable bollards be installed in existing tarmac?

Yes. Core drilling or excavation of the existing surface is standard practice. The bollard foundation chamber is installed, backfilled with concrete, and the surface reinstated. Surface disturbance is typically 500–700mm diameter.
