When it comes to protecting your home or business, the company you choose to install and maintain your security systems matters just as much as the equipment itself. A poorly installed intruder alarm, a CCTV system with blind spots, or an access control setup that hasn't been configured correctly can give you a false sense of security — and leave you exposed when it counts.

One of the most important things to look for when choosing a security company is SSAIB certification. In this guide, we explain what SSAIB is, why it matters, and what it means for you as a homeowner or business owner in Cardiff and South Wales.

What Is SSAIB?

The Security Systems and Alarms Inspection Board (SSAIB) is one of the UK's leading certification bodies for companies that install and maintain security and fire systems. It operates under the United Kingdom Accreditation Service (UKAS) — the national body for accreditation — which means SSAIB's certification schemes are independently assessed against internationally recognised standards.

SSAIB-certificated companies are audited regularly against industry standards including:

• BS EN 50131 — the European standard for intruder and hold-up alarm systems
• BS EN 62676 — the standard for video surveillance systems (CCTV)
• BS EN 60839 — the standard for alarm and electronic security systems, including access control
• PD 6662 — the UK guidance document for the application of BS EN 50131

To achieve and maintain SSAIB certification, a company must demonstrate that its engineers are competent, its installations meet the required standards, and its business practices — from documentation to customer service — are up to scratch. Certification isn't a one-off achievement; it requires ongoing compliance and regular re-inspection.

Why SSAIB Certification Matters for Your Insurance

This is often the most immediate practical reason for choosing a certificated company — and it's one that catches many homeowners and businesses off guard.

Most home and business insurance policies that include cover for theft or break-in will specify that any alarm system must be installed and maintained by an SSAIB or NSI certificated company. If your system was fitted by an uncertificated installer, your insurer may:

• Refuse to pay out on a claim following a break-in
• Reduce the settlement amount
• Invalidate the relevant section of your policy entirely

This isn't a technicality buried in the small print — it's a standard condition across most major insurers. Before you commit to any security installer, check your policy wording. If it requires SSAIB or NSI certification, that requirement must be met for your cover to be valid.

For businesses, the stakes are even higher. Commercial property insurance, employers' liability, and contents cover can all be affected. A single refused claim following a burglary could cost far more than the difference in price between a certificated and uncertificated installer.

What SSAIB Certification Means in Practice

Qualified, Vetted Engineers

SSAIB-certificated companies must employ engineers who are properly trained and qualified to work on the systems they install. This includes both technical competence — knowing how to design, install, and commission a system correctly — and personal vetting. Engineers working in homes and businesses must be screened appropriately, giving you confidence about who you're letting through your door.

Installations That Meet British and European Standards

An SSAIB-certificated installation isn't just "fitted" — it's designed and installed to meet the relevant British and European standards for that system type. For intruder alarms, this means the system is graded correctly for the risk level of the property, detectors are positioned to provide adequate coverage, and the panel is configured to respond appropriately. For CCTV, it means cameras are positioned to capture evidential-quality footage, with appropriate resolution, field of view, and storage. For access control, it means the system is configured to restrict access correctly and maintain an audit trail.

Ongoing Maintenance to a Recognised Standard

Installation is only half the picture. An SSAIB-certificated company will maintain your system to the same standard it was installed to. This means regular servicing, documented inspection reports, and prompt response to faults. A system that isn't maintained correctly will degrade over time — detectors become less sensitive, batteries fail, and software goes out of date. Certificated maintenance keeps your system performing as it should.

Police Response Eligibility

For intruder alarm systems, SSAIB certification is a prerequisite for police response. In the UK, the police will only respond to an alarm activation if the system has been installed and is maintained by an SSAIB or NSI certificated company, and the alarm is registered with a recognised alarm receiving centre (ARC). Without this, your alarm may sound — but the police won't come.

For businesses in particular, police response can be the difference between a would-be burglar being deterred or apprehended, and a break-in going unchallenged.

A Formal Complaints and Redress Process

SSAIB-certificated companies are bound by a code of practice and a formal complaints procedure. If something goes wrong — a dispute over an installation, a maintenance issue that isn't resolved — you have a clear route to escalate the matter through SSAIB. With an uncertificated company, your only recourse is through the courts.

Intruder Alarms: Why Certification Matters

An intruder alarm system is only as good as its design and installation. The grade of the system — from Grade 1 (low risk, domestic) to Grade 4 (high risk, commercial) — must be matched to the risk profile of the property. An SSAIB-certificated engineer will carry out a proper risk assessment and specify the correct grade, detector types, and coverage.

A common issue with uncertificated installations is false alarms. Poorly positioned detectors, incorrect sensitivity settings, and inadequate commissioning all contribute to false alarm rates. High false alarm rates are not just an annoyance — they can result in the police withdrawing response from your property entirely.

SSAIB-certificated companies are required to keep false alarm rates within acceptable limits and to investigate and resolve persistent false alarm issues. This protects both you and the wider community.

CCTV: Why Certification Matters

CCTV is one of the most visible forms of security, but a poorly designed system can be almost useless as evidence. Common problems with uncertificated CCTV installations include:

• Cameras positioned to capture the top of a person's head rather than their face
• Insufficient resolution to identify individuals or read number plates
• Inadequate storage — footage overwritten before an incident is reported
• Poor night-time performance — cameras that produce unusable footage in low light

An SSAIB-certificated CCTV installation is designed to produce footage that is actually useful — for identifying suspects, supporting insurance claims, and providing evidence to the police. The system will be specified and installed to BS EN 62676, with cameras positioned and configured to capture what matters.

There are also legal obligations around CCTV, particularly for businesses. Under UK GDPR and the Data Protection Act 2018, you must handle CCTV footage lawfully, display appropriate signage, and respond to subject access requests. An SSAIB-certificated company will advise you on your obligations and ensure your system is configured to help you meet them.

Access Control: Why Certification Matters

Access control systems — from simple keypad entry to multi-site card and biometric systems — need to be designed, installed, and configured correctly to do their job. An SSAIB-certificated installation will ensure:

• Access levels are correctly configured — the right people can access the right areas, and no one else can
• The system maintains a reliable audit trail — you can see who accessed which door and when
• Fail-safe and fail-secure modes are set appropriately — in a power failure or fire alarm activation, doors behave as they should
• Integration with other systems — where access control is linked to intruder alarms or CCTV, the integration is properly commissioned

Access control failures can have serious consequences — from security breaches to fire safety issues if doors don't release correctly during an evacuation. Getting the installation right matters.

How to Verify a Company's SSAIB Certification

Before appointing any security company, you can verify their certification directly on the SSAIB website at ssaib.org. The public register lists all currently certificated companies, the systems they're certificated for, and the geographic areas they cover.

Don't rely solely on a company's own claims — check the register. Certification can lapse, and a company that was certificated in the past may no longer hold current certification.
