In an increasingly unpredictable world, the need for robust security solutions has never been more paramount. At OC Services, we take pride in being Surrey's top choice for security solutions, particularly our exceptional intruder alarm systems. Also known as burglar alarms, these systems play a crucial role in protecting your premises against unauthorised access and theft.

Equipping your building with an efficient Intruder Alarm System is one of the most effective ways to shield your property from intruders. Regardless of whether you own a sprawling commercial space or a cosy home, ensuring that all entry points—doors, windows, and other vulnerabilities—are secure is vital for the safety of your family, employees, and possessions. Research indicates that properties with effective alarm systems are three times less likely to experience a break-in compared to those without security measures. This compelling statistic highlights the significance of having an intruder alarm system installed, making it an essential consideration for all property owners and tenants.
At OC Services, we understand that security is not a one-size-fits-all approach. Every individual and property comes with its own unique requirements, possessions that need safeguarding, and loved ones that deserve protection. This is why we are committed to delivering bespoke security solutions tailored to meet the distinctive needs of each client.

When you reach out to us for a new Intruder Alarm System, the first step in our process is to conduct a thorough security survey of your property. What sets OC Services apart is that this vital service is offered free of charge, and we will schedule it at a time that is most convenient for you. Our approach is collaborative; we will walk through your premises together, meticulously assessing various factors such as entry points, the type and construction of the property, its size, and the potential risks of break-ins.
During this survey, we go beyond just identifying vulnerabilities. We engage in meaningful conversations about your specific security needs. For instance, do you require the ability to arm different parts of your property separately, such as securing the downstairs areas while you remain upstairs at night? Understanding these facets allows us to personalise your security solution truly.
The insights gathered from our security survey enable us to determine the appropriate security grade and perimeter for your system. This is not merely a technical exercise but a foundational aspect of our commitment to your safety. Based on our assessment, we will produce a detailed System Design Proposal that encapsulates not only your security requirements but also aligns with your insurance stipulations.
When it comes to security systems, the right installation is crucial to ensure functionality and effectiveness. At OC Services, we pride ourselves on our professionalism and adherence to the highest industry standards. We exclusively install Grade 2 – 4 systems that fully comply with European Standards BS EN 50131, PD 6662, and SSAIB Codes of Practice. Our skilled technicians boast extensive experience in installing a wide range of security systems. They diligently ensure that every component is set up perfectly, guaranteeing maximum protection. This professional installation approach minimises the risk of installation errors that could jeopardise your security.
A successful security installation goes beyond just placing devices and sensors; it requires efficient groundwork and cabling. Our team handles all necessary groundwork and cabling artfully, ensuring a clean setup that integrates seamlessly with your property. We understand the importance of maintaining the aesthetic value of your premises, which is why we prioritise a solution that avoids disruption and maintains your property’s integrity.
No two properties are alike, and neither are their security needs. Our customised system programming allows us to tailor alarm systems to meet your specific requirements. Whether you run a bustling retail store or manage a calm family home, our tailored solutions ensure that your system operates efficiently and effectively in line with your unique needs.
Upon the successful installation of your Intruder Alarm System, you will receive an official SSAIB Certificate of Conformance. This certificate is your proof of assurance that your alarm system has been professionally installed to meet regulatory standards, which is often a requirement for many insurance companies. We believe that peace of mind should extend beyond installation; that’s why every system we install is backed by a 12-month guarantee.
To further enhance your peace of mind, we offer various monitoring options that ensure swift reactions to potential security breaches. Whether you prefer a monitored response that involves immediate police intervention or an internal alert system, we can provide a solution that fits your lifestyle. Our remote monitoring services operate 24/7, ensuring continual surveillance of your property and rapid response to any alarms triggered.
Understanding how to use your security system effectively is essential for all users. Therefore, we offer comprehensive training sessions that empower you and you to utilise the system fully. Our dedicated team provide you with the necessary knowledge and skills, to ensure you fully understand the system and can respond efficiently to alarms, and system notifications. During our handover we also provide guidance on compliance with relevant legislation. Additionally, we offer post-installation training for new tenants and employees, ensuring everyone is equipped with the knowledge to maintain your security system effectively.
We believe in proactive care for your security systems. Our competitive annual preventative maintenance and servicing packages are designed to keep your system in peak condition. Regular check-ups and servicing not only help in identifying potential issues before they escalate but also extend the lifespan of your equipment, ensuring long-term protection for your premises.
Corrective Maintenance: Despite the best preventative measures, technical issues can occasionally arise. Our dedicated team provides swift corrective maintenance to resolve any faults, ensuring your security system remains operational. Our approach minimises any downtime, prioritising the safety of your premises at all times.
