Understanding the difference between fixed, removable, and telescopic bollards is essential for specifying access control or traffic management correctly. Each serves a different operational need — and choosing the wrong type is a common and costly mistake.
Three-Way Comparison
| Factor | Fixed Bollard | Removable Bollard | Telescopic Bollard |
|---|---|---|---|
| Access when lowered/removed | None | Full (when removed) | Full (when lowered) |
| Operation speed | N/A | 1–5 minutes | 10–30 seconds |
| Key/tool required? | N/A | Yes | Yes (key or padlock) |
| Cost (supply) | £150–£800 | £200–£600 | £250–£700 |
| Suitable for frequent use? | N/A | No (slow operation) | Yes |
| PAS 68 available? | Yes | Yes (in-situ) | Yes (in-situ) |
Fixed Bollards: Permanent Protection
A fixed bollard is permanently embedded — it cannot be moved without excavation. It provides the highest level of physical deterrence because there is no mechanism to compromise.
Installation Methods
- Root-mounted: Post extends 600–900mm below ground into concrete — simplest method
- Core-filled: Set into a circular core drilled in existing concrete or tarmac
When to Specify Fixed
- Permanent vehicle exclusion — no access ever required
- Security is the primary driver (PAS 68 applications)
- Risk of mechanism compromise is unacceptable
- Minimum maintenance requirement
Cost: £150–£800+ supply; £230–£1,000 installed
Removable Bollards: Controlled, Occasional Access
Removable bollards use a socket system — a sleeve in the ground — into which the bollard post slots. A key tool or padlock locks it in position.
Mechanism Types
- Lift-out with lockable key: Dedicated key releases a locking mechanism (most common)
- Padlock-secured: Padlock prevents removal; key releases padlock
- Gravity socket: No locking mechanism — for access control only, not security
Socket Quality is Critical
Poor-quality sockets suffer water ingress, corrosion, and mechanism failure. Always specify hot-dip galvanised sockets. Premium sockets incorporate drainage holes and stainless steel locking components.
When to Specify Removable
- Delivery-only access (3–5 times per week or less)
- Emergency vehicle access routes
- Event management
- Seasonal access
Cost: £200–£600 supply; £350–£900 installed (including socket)
Telescopic Bollards: Frequent, Quick Access
Telescopic bollards consist of a permanently fixed outer sleeve, with an inner post that raises and lowers. When raised: full-height bollard. When lowered: flush or low-profile cap at ground level.
How They Work
- Key inserts into bollard top
- Inner post pushes down into outer sleeve (or raises)
- Mechanism locks in both up and down positions
High-quality models withstand 50–100+ operations per day and 10,000+ cycles without significant mechanism wear.
When to Specify Telescopic
- Pedestrianised high streets with multiple daily delivery windows
- Staff car parks with shift changeovers
- Any application where bollards are operated multiple times daily
Cost: £250–£700 supply; £400–£1,050 installed
Decision Framework
-
Is vehicle access ever required?
- Never → Fixed
- Occasionally (weekly or less) → Removable
- Frequently (daily or more) → Telescopic or automatic
-
Security level?
- Deterrence only → Standard steel, any type
- Certified security → PAS 68 / IWA 14 rated in any type
-
Operation frequency?
- Rare → Removable
- Multiple times daily → Telescopic
- Unmanned or very frequent → Automatic rising
Important: PAS 68 / IWA 14 ratings apply to the bollard in the raised/installed position only. A removable bollard with its post removed provides zero vehicle security.
