The service
Barrier and gate installation, repair and maintenance
Automatic barriers and gates control who and what comes onto a site, and when a barrier or gate fails, that control disappears. Whether it is a rising arm barrier at the entrance to a business park, a sliding gate securing a distribution yard, or a swing gate at a school car park, the mechanism needs to open and close reliably, hold securely, and behave safely around vehicles and pedestrians every single time. At Argents Installations Ltd we supply, install, repair and maintain barriers and gates across commercial, industrial and public sites throughout Peterborough, London and the surrounding counties.
Our work covers rising arm and boom barriers, sliding gates, swing gates, bi-folding gates, automatic bollards and the access control equipment that operates alongside them, from intercoms and keypads to card readers and number plate recognition. We install new systems from first-fix through to commissioning, and we retrofit automation and access control to existing manual gates where a site is upgrading its security without replacing the gate itself.
Gate and barrier systems are Gate Safe territory: moving vehicle-scale equipment operating around pedestrians and vehicles, subject to the safety requirements set out for powered gates. Our engineers are Gate Safe accredited, IPAF trained and CSCS card holding, and every installation and safety inspection follows that framework, including force testing, safety edge checks and correct signage. We provide RAMS and method statements on request for sites that require them before work begins.
As with everything we do, the process starts with a free, no-obligation site survey. Barrier and gate specification depends heavily on ground conditions, power availability, traffic volume, and the level of access control actually required, so we do not quote pricing over the phone without seeing the site. A written quotation follows, with commercial account terms available for clients managing multiple sites or ongoing maintenance requirements.
Business parks, industrial estates and logistics yards
Rising arm barriers and sliding gates control vehicle access to shared sites, distribution yards and industrial estates, often needing integration with intercoms, card access or number plate recognition for multiple tenants or high vehicle turnover.
Car parks and managed sites
Pay-and-display car parks, staff car parks and managed residential-commercial sites rely on barriers that cycle reliably many times a day, with ticketing or card access integration and robust safety features around pedestrians.
Schools, healthcare sites and public buildings
Gates and barriers controlling vehicle access around schools, healthcare premises and public buildings need to prioritise pedestrian safety, with correctly specified safety edges, obstruction detection and clear signage around children and vulnerable users.
What it costs to leave it
The risks of a poorly maintained or badly specified barrier or gate
Powered gates and barriers are large moving pieces of equipment operating close to people and vehicles, and both safety and site security depend on them being correctly specified, properly maintained and repaired without delay when something goes wrong.
Safety risk to pedestrians and vehicles
A gate or barrier with worn safety edges, a faulty obstruction sensor or incorrect force settings is a genuine safety hazard around pedestrians, cyclists and vehicles. Gate Safe guidance exists precisely because powered gates have caused serious injuries when poorly maintained.
Site access failure
A barrier stuck in the closed position stops every vehicle getting onto site; stuck open, it removes the access control the site relies on entirely. Either way, normal site operations stop until an engineer attends.
Escalating mechanical and electrical faults
Barriers and gates are exposed to weather, vehicle impact and constant cycling, so small issues such as a labouring motor, a misaligned track or a failing control board tend to worsen quickly if left unaddressed, turning a simple adjustment into a major repair.
Mistakes we get called out to fix
- Installing a gate or barrier without a proper site survey covering ground conditions, power supply and traffic patterns.
- Skipping annual safety inspections because the gate 'seems to be working fine' day to day.
- Ignoring warning signs like slow operation, unusual noise, or the gate stopping short of full open or closed.
- Ignoring Gate Safe guidance on safety edges and force limits when specifying or repairing a powered gate.
- Using an installer unfamiliar with the specific barrier or gate brand, leading to incorrect programming or safety settings.
- Failing to maintain access control components such as intercoms, keypads and card readers alongside the mechanical gate itself.
Our process
Our barrier and gate process
Step 1
Free site survey
An engineer assesses ground conditions, power supply, traffic flow, pedestrian routes and the access control method you need, discussing priorities around security, safety and appearance.
Step 2
Written, no-obligation quotation
You receive a clear written quote covering the barrier or gate specification, groundworks, power supply and access control equipment, with commercial account terms available for site owners and managing agents.
Step 3
Scheduled installation
Installation is scheduled to minimise disruption to site access, with RAMS and method statements provided on request and traffic management planned where required.
Step 4
Commissioning, testing and handover
The system is force-tested, safety edges and obstruction detection are verified, and access control equipment is configured and demonstrated before handover, in line with Gate Safe requirements.
Step 5
Ongoing service and support
Planned maintenance contracts, including annual Gate Safe inspections, keep the system compliant and reliable, backed by our engineers for repairs and a 12-month warranty on all work.

In detail
Barriers and gates in depth
Specifying and maintaining automatic barriers and gates properly means understanding the mechanisms, the access control layer that sits on top of them, and the safety framework that governs powered gates. Below is a closer look at how we approach each of these.
Barrier and gate types
Rising arm barriers are the standard choice for controlling vehicle access at car parks, business parks and industrial sites, using a pivoting boom arm to block a single lane. They are fast-cycling, relatively low-cost to install and well suited to high-traffic sites where a full gate would be impractical.
Sliding gates run along a track parallel to the boundary line and suit sites with limited space in front of the opening, such as narrow yard entrances or sites close to a public footpath. Swing gates open outward or inward on hinges and suit wider openings with sufficient clear space, while bi-folding gates fold in sections to open quickly within a smaller footprint, often used where speed of operation matters, such as fire station or emergency vehicle access.
Automatic bollards provide an alternative or additional layer of vehicle control, particularly for pedestrianised areas that need occasional vehicle access, and can be integrated with the same access control systems used for gates and barriers.
Access control integration
A barrier or gate is only as good as the access control method operating it. We install and integrate intercoms, keypads, proximity card and fob readers, and automatic number plate recognition systems, matched to how a site actually needs to manage access, whether that is a single shared code, individual credentials for staff and visitors, or automated recognition for known vehicles.
For multi-tenant business parks and managed sites, access control often needs to distinguish between different user groups, provide audit trails, and integrate with existing security or building management systems. We specify and configure systems to meet those requirements rather than fitting a generic solution.
Remote monitoring and management is increasingly common for barriers and gates across multiple sites, allowing a site manager or security team to open, close or troubleshoot a barrier without attending in person, and we advise on this where it suits the client's operation.
Safety, Gate Safe and compliance
Powered gates and barriers fall under Gate Safe guidance because of the genuine safety risks they present around pedestrians and vehicles if incorrectly installed or maintained. Correct force limiting, properly fitted and tested safety edges, photocells or other obstruction detection, and clear warning signage are not optional extras, they are fundamental to a compliant installation.
Our engineers carry out Gate Safe inspections as part of planned maintenance contracts, checking force settings, safety device function and structural condition of the gate or barrier and its fixings. Where an existing gate on site does not meet current safety expectations, we advise on the remedial work needed to bring it up to standard rather than simply signing it off.
We provide RAMS and method statements on request for installation and maintenance works, supporting sites that need to evidence compliance as part of their own health and safety management.
Repair, maintenance and common faults
The faults we most commonly attend include motors labouring or failing under repeated cycling, control boards and electronics failing after power surges or water ingress, tracks and wheels on sliding gates wearing or becoming misaligned, and safety edges or photocells failing or being knocked out of alignment by vehicle impact or weather.
Planned maintenance visits allow us to grease and adjust moving parts, test safety devices, check control settings and identify components nearing the end of their working life before they fail during operation. For sites where the barrier or gate is the only access point, a scheduled maintenance contract materially reduces the risk of an unplanned closure.
Where repair is needed following damage, wear or a vehicle impact, we assess whether components can be repaired or need replacing, and carry out the work with a 12-month warranty, always aiming to restore full, safe operation rather than a temporary fix.
Commercial versus residential and site variations
Our barrier and gate work is focused on commercial, industrial and public sites, which typically means higher cycle counts, multiple users, integration with wider access control or security systems, and a greater emphasis on managing pedestrian safety around vehicle movements than a single domestic gate installation would involve.
Ground conditions, power supply routing and traffic flow vary significantly from site to site, which is why every job starts with a proper survey rather than a standard specification. Commercial clients also typically require planned maintenance contracts, Gate Safe inspection records and RAMS documentation as part of their own compliance processes, all of which we provide as standard on request.
