What we install
Types of security gates, barriers, bollards and blockers.
From simple electronic sliding gates to automated rising bollards and road blockers. We recommend the type from your site, threat level, traffic volume and integration needs.
Security gates
Sliding, swing, bi-folding and speed gates, with automatic opening. Sliding gates run on tracks and suit tight sites; swing gates go up to 3m x 6m and take about 30 seconds to open, best for medium traffic; bi-folding gates open quickly across large entrances without tracks.
Rising arm barriers
The usual choice for car parks. Straight beams are simple and reliable; beam and security kits add protection.
Security bollards
Fixed, semi-fixed and rising bollards for car parking and pedestrian areas, programmable for timed activation.
Road blockers and rising kerbs
Surface or trench mounted blockers, also called cheese wedges, for stronger deterrence than a car park barrier.

How the main barrier types compare.
The right choice depends on traffic volume, available space and how quickly the entrance must open.
| Type | How it works | Best for |
|---|---|---|
| Sliding gate | Runs on a track and does not swing into the roadside | Sites with limited space |
| Swing gate | Hinged leaves that open in an arc, slower than a sliding gate | Medium-traffic entrances |
| Bi-folding gate | Folding leaves that open quickly with no track | Large entrances |
| Rising arm barrier | A straight beam, with optional security kit, that lifts for each vehicle | Car parks and controlled vehicle lanes |
| Fixed or semi-fixed bollard | Permanent posts, or posts that can be removed or repositioned | High-security areas and changing layouts |
| Rising bollard | Retractable posts that lower and rise as required | Entrances that must open to authorised vehicles |
| Road blocker or rising kerb | A surface or trench mounted plate that rises to stop vehicles | Hostile vehicle mitigation and high-risk sites |
Integrated security
Barriers that work with your other security systems.
Our gates, barriers and bollards integrate with the systems you already run, or with new ones we install, so every part communicates.
- CCTVCameras covering the entrance for monitoring and evidence. See CCTV installation.
- ANPRAutomatic number plate recognition for hands-free entry of registered vehicles.
- Access controlFobs, cards and readers that authorise entry. See commercial access control.
- IntercomsAudio or video entry so visitors can be verified at the gate. See entry phone installation.
- Pedestrian gates and turnstilesControl of foot traffic at the same entrance.
- Lighting and fire systemsBollards and gates that respond to timed lighting and fire system signals.
The result is automated vehicle entry, audit logging and central management from a single platform. For networked security across the site, see IP security system installation.

All of them can be integrated with our access control solutions, including CCTV, lighting and ANPR camera hardware and software, or with your own security systems, so each part communicates with the others.
Our service covers planning, design, recommendations, installation, testing and follow-up support. We work around your business schedule to keep downtime low and get the system working as quickly as possible.
Hostile vehicle mitigation
Road blockers and rising kerbs are heavy-duty security measures for controlling vehicle flow. We install PAS 68 and IWA 14-1 rated bollards, road blockers and rising kerbs designed to stop vehicles in hostile vehicle attacks. PAS 68 is a counter-terrorism impact standard, and road blockers that meet it can stop a fully loaded 7,500kg lorry travelling at up to 50mph.
These measures are used at critical infrastructure sites, government buildings, stadiums and public spaces. The rating that suits your site depends on the approach roads, vehicle speeds and the risk assessment.
Groundwork for trench-mounted systems
Rising bollards, road blockers and rising kerbs need proper groundwork to work reliably and last. Trench-mounted systems need a site survey and extensive groundwork so the mechanism is securely installed below ground. Surface-mounted versions need less excavation. ACCL provides the site survey and the groundwork as part of the installation.
ANPR barrier systems explained
Automatic number plate recognition uses cameras to read vehicle registration plates. Linked to a barrier or gate, it identifies authorised vehicles and opens without the driver doing anything. Unknown vehicles are held until someone verifies them, for example over an intercom. Each entry is logged, which helps with car park management and security audits.
Matching the barrier to your traffic
Traffic volume, available space and opening time decide the type. A sliding gate suits a narrow site because it does not swing into the road; a swing gate is slower and better for medium traffic; a bi-folding gate opens quickly across a wide entrance. Rising arm barriers handle frequent car park traffic, while bollards and blockers trade speed for stopping power.
Barrier maintenance and servicing
Gates, barriers and bollards are mechanical and need regular attention. ACCL offers planned maintenance including mechanical servicing, safety checks, control system updates and repair call outs, to keep your perimeter security working. Bollards can also be reprogrammed as your opening times change.
What affects security barrier cost
Cost depends on the barrier type, the number of entrances, groundwork and trench work, any hostile vehicle rating, the access control, ANPR, CCTV and intercom integration, and maintenance.
After a free consultation and site survey we send an itemised quote before any work starts.
Why choose ACCL for security barriers
ACCL designs and installs the cabling, networks and security systems that barriers depend on, so the barrier, its readers, cameras and intercoms are delivered by one team. At Cabot Financial’s Kings Hill campus, for example, we installed 43 cameras and access control on 32 doors as one platform and have maintained it since 2019 (case study).

Before you book
Security barrier installation FAQs
What types of security barrier do you install?
ACCL installs automated and manual security gates (sliding, swing, bi-folding and speed gates), rising arm barriers, fixed, semi-fixed and rising bollards, and road blockers and rising kerbs. We recommend the right one from your site, threat level, traffic volume and integration needs, after a free consultation and a survey of the entrance.
Can security barriers integrate with CCTV and access control?
Yes. ACCL integrates barriers, gates and bollards with CCTV, ANPR, access control fobs and cards, and intercom systems. That gives automated vehicle entry, audit logging and central management from a single platform. We can connect to the systems you already have or install new ones as part of the same project.
What is ANPR and how does it work with barriers?
ANPR, automatic number plate recognition, uses cameras to read vehicle registration plates. When it is linked to a barrier or gate, authorised vehicles are identified automatically and the barrier opens without the driver doing anything. Unauthorised vehicles are held until someone verifies them manually, for example through an intercom at the entrance.
Do you install hostile vehicle mitigation (HVM) measures?
Yes. ACCL installs PAS 68 and IWA 14-1 rated bollards, road blockers and rising kerbs designed to stop vehicles in hostile vehicle attacks. They are used at critical infrastructure sites, government buildings, stadiums and public spaces. The right rating depends on your approach roads, likely vehicle speeds and risk assessment, which the survey looks at.
Do barriers need a site survey?
Yes. A survey checks the entrance width, traffic, ground conditions, power and data routes, and the systems the barrier must connect to. Trench-mounted road blockers and rising bollards need a survey and extensive groundwork before installation. ACCL carries out the survey free of charge and uses it to recommend the barrier type and price the work.
How long does security barrier installation take?
Timescales vary by barrier type and site complexity. A simple rising arm barrier can be installed in one to two days, while bollard arrays or road blockers that need groundwork may take one to two weeks. ACCL provides a detailed programme of works after the site survey, planned around your business schedule.
Do you provide maintenance for security barriers?
Yes. ACCL offers planned maintenance for gates, barriers and bollards, including mechanical servicing, safety checks, control system updates and repair call outs, to keep your perimeter security working. Regular servicing also catches wear on moving parts early, before it stops the entrance opening for the vehicles and people who need it.
What areas do you cover for security barrier installation?
ACCL installs security barriers across London, Kent, Surrey and the wider South East, from our offices at the Royal Exchange in the City of London and in Orpington, Kent. Book a free consultation and one of our engineers will survey the site and recommend the right gates, barriers or bollards for it.
How much does a security barrier installation cost?
It depends on the barrier type, the number of entrances, groundwork, any hostile vehicle rating, integration with access control, ANPR, CCTV and intercoms, and maintenance. We do not quote a fixed price without that detail. After a free consultation and site survey, we send an itemised quote before any work starts.
