The equipment matters, but so do the installer’s accreditations, their grasp of compliance, and their ability to support the system for years after handover. ![AEL Systems 2](https://www.aelsystems.co.uk/hs-fs/hubfs/AEL%20Systems%202.jpg?width=595&height=394&name=AEL%20Systems%202.jpg) A good installer does more than supply and fit equipment. They assess your premises, identify your risks and recommend a solution that fits how your business operates and what it can spend. These ten questions will help you tell the difference, whether you’re protecting an office, warehouse, retail unit, school or healthcare site. **Quick checklist** 1. Which accreditations do you hold, and can I verify them? 2. Can the system qualify for police response (a URN)? 3. Which standards will the installation meet? 4. Will you carry out a site survey and risk assessment? 5. How will you help us prevent false alarms? 6. How do you approach cybersecurity and equipment selection? 7. Will our CCTV support UK GDPR compliance? 8. What monitoring, maintenance, and support do you provide? 9. What insurance, health and safety and subcontracting arrangements do you have? 10. Can you provide references and a fully itemised quote? ## 1. Which Accreditations Do You Hold, and Can I Verify Them? Start here. Ask which accreditations the installer holds, which services each one covers, and how you can check them. Logos on a website prove nothing on their own. NSI and SSAIB both publish online company directories, and BAFE does the same for fire services. Always confirm that accreditation covers the exact service you need. One certificate rarely covers everything a company offers. Our security services are approved by NSI Gold standards, and our fire safety services are BAFE certified. We also hold Constructionline, CHAS, SafeContractor and ISO 9001, and you’re welcome to check out any of them on our website. ## 2. Can the System Qualify for Police Response? If you’re considering a monitored intruder alarm, ask whether it can qualify for a police Unique Reference Number (URN). Under the National Police Chiefs’ Council (NPCC) policy, police in England, Wales and Northern Ireland only respond to remotely monitored systems that meet its requirements, and each eligible system is issued a URN. Eligibility depends on the type of system, the monitoring arrangements, the technical standards applied, and installation and maintenance by a company approved by a UKAS-accredited inspectorate. The 2025 update to the policy also makes supplying the installer’s Certificate of Compliance an explicit part of URN applications and reinstatements. Before you proceed, ask your installer: - Is the proposed system eligible for a URN? - Which installation and alarm confirmation standards apply? - Who handles the application and supporting documents? - What fees are payable, and who pays them? - What are our responsibilities after installation? A URN is not a guarantee that police will attend every activation. Response depends on the policy and the circumstances at the time. For more detail, see the [NSI guidance on police response](https://www.nsi.org.uk/national-police-chiefs-council-policy-on-police-response/) and the [Police Security Systems website](https://www.policesecuritysystems.com/). ## 3. Which Standards Will the Installation Meet? Standards should be agreed upon before work starts, not discovered after the equipment is on the wall. Depending on the system, the relevant standards may include: For police response, monitored systems installed after June 2012 must conform to PD 6662 and BS 8243. Your installer should confirm which editions apply and explain how the design meets them. This matters most where security is a condition of your insurance, lease or contract. Ask for specifications and commissioning certificates to be part of the project handover. A new fire alarm, for example, should be designed around the building, its occupancy and your fire risk assessment, not simply copy the layout of the old system. ## 4. Will You Carry Out a Site Survey and Risk Assessment? Every commercial building carries different risks. A retail unit worries about theft and forced entry. A warehouse needs perimeter detection, controlled access, and coverage of loading bays. A school or hospital adds safeguarding, visitor management and restricted areas. Your installer should assess the site before recommending any equipment. A good survey looks at: - Building layout and entry points - Existing CCTV, alarms and access control, and what can be reused - Vulnerable areas, lighting and environmental conditions - Staff, visitor and contractor movements - Network infrastructure and connectivity - Fire safety requirements, where relevant - Future expansion - Working hours and how the installation will be phased around your operations Without a proper survey you risk blind spots, badly placed detectors, access control that gets in the way of daily work, and money spent on equipment that doesn’t address your actual risks. Ask whether the survey is included in the proposal and whether the final design will be tailored to your premises. We design every solution around the client’s site and requirements rather than selling a standard package. **Considering an upgrade?** [Request a site survey](https://www.aelsystems.co.uk/request-a-site-survey) to find out where your biggest vulnerabilities are. ## 5. How Will You Help Us Prevent False Alarms? False alarms disrupt operations, waste staff time and, for policed systems, put police response at risk. Under the NPCC policy, a system with a URN receives a Level 1 response until three false calls occur in a rolling 12-month period. After that, Level 3 applies: police response is withdrawn, and only keyholder attendance is possible. Specific conditions must be met before response can be reinstated. Ask your installer how they will keep unwanted activations down: - **Correct design:** detectors suited to the environment and positioned properly. - **Alarm confirmation:** technology that helps establish whether an activation is a genuine incident. - **User training:** staff who know how to set, unset, and manage codes correctly. - **Commissioning and handover:** thorough testing and clear instructions. - **Ongoing maintenance:** regular servicing to catch faults early. A good installer will also investigate recurring activations and recommend corrective action, rather than simply resetting the panel. ## 6. How Do You Approach Cyber Security and Equipment Selection? IP cameras, recorders, access control and remote monitoring platforms often sit on your business network or connect to cloud services. Poorly configured or unmaintained, they can become a way in for attackers. The NPCC’s 2025 requirements reference the BSIA’s Cybersecurity Code of Practice for Safety and Security Systems, which shows how seriously the industry now takes the issue. It’s also sensible to understand the manufacturer, country of manufacture, supply chain, and support arrangements behind the equipment you’re offered. The UK Government has told departments to stop installing Chinese-linked surveillance cameras at sensitive sites. Those restrictions apply to government sites, not to every commercial installation, but they’ve made supply-chain questions a normal part of buying security equipment. We recommend equipment on a risk basis. Where a client sector or policy calls for it, we can specify alternatives from our wider range of manufacturer partners, including Axis, Avigilon and Hanwha. A good installer will explain the strengths and limits of what they propose and help you make an informed choice. This matters most for organisations handling sensitive information, critical infrastructure or multiple connected sites. ## 7. Will Our CCTV Support UK GDPR Compliance? Commercial CCTV protects people and property, but recording identifiable individuals creates data protection duties. Installing cameras does not make a business compliant. As the operator, your organisation is the data controller and is responsible for its lawful basis, transparency, security and retention. Your installer can help by specifying and configuring equipment that supports responsible data handling. Ask what they provide, such as: - User permissions and secured access to live and recorded footage - Retention settings and automatic deletion - Audit and access logs - Information on storage and remote access - Camera positioning that avoids unnecessary recording You’ll also need to consider signage, privacy information, internal policies, and whether a Data Protection Impact Assessment (DPIA) is required. A DPIA is needed where processing is likely to result in a high risk for individuals. UK GDPR sets no single retention period for CCTV, so you should decide on and document one you can justify and avoid keeping identifiable footage longer than necessary. The [ICO’s video surveillance guidance](https://ico.org.uk/for-organisations/guide-to-data-protection/key-dp-themes/video-surveillance/) is the best starting point. Raising these points before installation lets you make better decisions about camera placement, storage, and access. ## 8. What Monitoring, Maintenance and Support Do You Provide? Installation is only the start. Ask what happens afterwards, including: - **24/7 monitoring:** which alarm receiving centre (ARC) is used, and how alerts are handled. - **Signalling:** As the UK moves from analogue to digital phone lines, ask how alarm signals will reach the ARC. Modern monitored systems typically use IP or dual-path signalling rather than a single phone line. - **Planned preventative maintenance:** how often visits happen and what is tested. - **Emergency callouts:** coverage area, hours and guaranteed response times. - **Technical support:** who you call when a camera stops recording or a door reader fails. - **Upgrades:** whether the system can grow with your business. - **Contract terms:** length, renewal, cancellation, service levels and charges at the end of the agreement. Police advice on monitoring contracts includes avoiding long-term commitments. Some installers only install. Others also maintain and monitor. A reliable provider will tell you exactly what’s included, what’s chargeable, and how faults are handled. That matters most if your premises are unattended out of hours. See our [monitoring](https://www.aelsystems.co.uk/monitoring) and [maintenance](https://www.aelsystems.co.uk/security-system-maintenance-uk) services. ## 9. What Insurance, Health and Safety and Subcontracting Arrangements Do You Have? Commercial installations involve working at height, drilling into structures, accessing electrical infrastructure, and coordinating with other trades, often in occupied buildings. Ask for evidence of: - **Public liability insurance:** Cover for specified third-party injury or property damage, subject to policy terms. - **Professional indemnity insurance:** Cover for certain professional negligence claims, where applicable. - **Employer’s liability insurance:** Required for most UK employers, subject to exemptions. - **Risk assessments and method statements (RAMS):** For your site and the work involved. ## 10. Can You Provide References and a Fully Itemised Quote? Experience in a similar environment is valuable. Fitting CCTV in a small office is very different from designing an integrated solution for a school, a warehouse, or a multi-site organisation. Ask for references or case studies from comparable clients and speak to a recent customer if you can. Useful questions for references: - Did the final invoice match the quote? - How was the installation managed around your operations? - What commissioning documents and training did you receive? - How has the system been performed since, and how responsive is support? - Equipment, models and quantities - Installation labour, cabling and network requirements - Configuration and integration - Testing, commissioning, training and handover documentation - Warranty terms - Monitoring and maintenance costs, and any subscriptions or licence fees - Payment terms and potential extra charges Then look closely at the quote. A good one itemises: Get written quotes from at least two suitable installers where practical, but don’t choose price alone. A cheaper quote may leave out commissioning, maintenance or equipment that another has included. ## Red Flags to Watch For Be cautious if a company: - Contacts you by cold call or doorstep sales - Cannot provide verifiable accreditations or explain what they cover - Recommends equipment without surveying your premises - Gives vague quotes without equipment specifications - Promises guaranteed security or guaranteed police response - Cannot say which standards apply - Offers little on maintenance, warranty or support - Pushes you to sign quickly or pay a large amount upfront without clear justification - Cannot explain how network-connected equipment will be secured - Claims your CCTV will be GDPR compliant without mentioning your own responsibilities A professional installer will welcome reasonable questions and answer them in plain English. ## Choosing an Installer for Your Sector The questions above apply everywhere, but priorities differ by premises: | **Sector** | **Typical priorities** | | --- | --- | | Offices | Entrance and reception CCTV, access control for restricted areas, out-of-hours intruder protection | | Schools and education | Controlled entry, visitor management, safeguarding, minimal disruption during installation | | Healthcare | Staff and patient safety, restricted clinical areas, sensitive information, continuous operation | | Warehouses and logistics | Perimeter protection, loading bay and vehicle access, stock security, out-of-hours monitoring | | Retail | Camera positioning, staff safety, stock protection, back-of-house access |   If you run several sites, ask whether the installer can deliver a consistent design, centralised management and one maintenance contract. ## Why Choose AEL Fire & Security?
