Does It Really Matter Whether Your Intruder Alarm Company Is Accredited?
When you’re looking for an intruder alarm installer in Hull or East Yorkshire, it’s tempting to go with whoever quotes the lowest price or can get to you quickest. But choosing an unaccredited installer can cost significantly more in the long run — through insurance complications, system failures, and work that doesn’t meet the standards your insurer or local authority expects.
Accreditation isn’t a marketing badge. It’s a verified, independently audited confirmation that a security company meets defined standards for the quality of their installations, the competence of their engineers, and the reliability of their ongoing service. This guide explains what SSAIB accreditation means in practice, why it matters for your intruder alarm system, and what to check before appointing any security company in Hull or East Yorkshire. You can verify our own accreditation status on our SSAIB accreditations page.
What Is SSAIB Accreditation?
The SSAIB — Security Systems and Alarms Inspection Board — is one of the UK’s two main certification bodies for security and fire alarm companies. The other is NSI (National Security Inspectorate). Both are UKAS-accredited certification bodies, recognised by insurers, local authorities, and the police across the UK, and both impose equivalent standards on their member companies. The choice of which body a security company is certified by makes little practical difference to you as a customer — what matters is that they hold current certification from one of the two.
To achieve and maintain SSAIB certification, a security company must:
Why Accreditation Matters for Intruder Alarm Systems
Meet defined installation standards
All intruder alarm installations must be designed and installed to PD 6662:2017 and BS EN 50131, which are the British and European standards that govern intruder alarm system design, equipment grading, and installation quality. An SSAIB accredited company cannot cut corners on equipment specification or installation method without risking their certification.
Employ competent, vetted engineers
SSAIB requires that all engineers working on installations and maintenance have been appropriately vetted and are competent to carry out the work. This includes background screening — relevant given that your security engineer will have access to your property and detailed knowledge of your alarm system.
Undergo regular independent audits
Accreditation isn’t a one-time assessment. SSAIB audits its member companies at regular intervals to verify that standards are being maintained. If a company fails an audit, their certification can be suspended or withdrawn. This ongoing scrutiny is what gives accreditation its value — it’s not something a company can earn once and then forget about.
Operate a complaints and redress process
SSAIB accredited companies must operate a formal complaints process, and the SSAIB itself provides a route for customers to raise concerns if they believe standards haven’t been met. This gives you a level of protection that simply doesn’t exist when dealing with an unaccredited installer.
Why Accreditation Matters for Your Insurance
This is the most immediately practical reason to use an accredited intruder alarm company — and the one most people discover too late.
Many UK home and business insurers require that intruder alarm systems are installed and maintained by an NSI or SSAIB accredited company as a condition of cover. This requirement is often buried in the small print of insurance policies and isn’t always highlighted at the point of sale.
If your alarm system was installed by an unaccredited company and you make a claim following a break-in, your insurer may:
- Reject the claim on the basis that the alarm system doesn’t meet their specified installation standard
- Reduce the settlement on the basis that the system was not properly maintained by a competent provider
- Void the relevant section of your policy entirely if accreditation was a stated condition of cover
For businesses in particular, this is a significant risk. Commercial property insurers are more likely to specify accreditation requirements than domestic insurers, and the financial consequences of a rejected claim are considerably higher.
Before appointing any intruder alarm company, check your insurance policy for any requirements relating to alarm installation and maintenance standards. If in doubt, call your insurer and ask directly.
Why Accreditation Matters for Police Response
In the UK, the police operate a policy on responding to intruder alarm activations that directly involves accreditation. Under the Association of Chief Police Officers (ACPO) Security Systems Policy, police forces will only respond to alarm activations from systems that are:
- Installed and maintained by an NSI or SSAIB accredited company
- Registered with the local police force through the correct notification process
- Operated within the terms of the ACPO policy, including false alarm management
If your alarm system was installed by an unaccredited company, you may find that your local police force will not respond to activations — regardless of whether the alarm is genuine. In practice this means that if your premises is broken into out of hours and the alarm activates, no police response may be forthcoming.
For businesses that rely on police response as part of their security strategy — particularly those without monitored systems — this is a critical consideration. Our intruder alarm monitoring service ensures your system is registered correctly and that activations are handled through an accredited Alarm Receiving Centre.
The Difference in Installation Quality
Beyond insurance and police response, there’s a straightforward quality argument for using an accredited company that’s easy to overlook when comparing quotes.
SSAIB accredited installers work to defined equipment grading standards. Intruder alarm equipment under BS EN 50131 is graded from Grade 1 (low risk, basic deterrence) to Grade 4 (high risk, commercial and high-value sites). An accredited installer will specify equipment at the appropriate grade for your property and risk level — not simply whatever happens to be cheapest or most readily available.
Unaccredited installers are under no obligation to follow these grading standards. In practice, this often means lower-grade equipment installed in situations where higher-grade equipment is appropriate — resulting in a system that looks the part but doesn’t perform to the standard your insurer expects or your security requires.
The difference is particularly relevant for:
Commercial premises — where the consequences of a system failure are greater and insurers are more likely to scrutinise the installation standard after a claim.
Properties with high-value contents — where the risk level justifies higher-grade equipment that an accredited installer will specify appropriately.
Properties with existing alarm systems — where an accredited installer taking over maintenance will identify whether the existing system meets current standards, rather than simply servicing whatever is already in place.
Our intruder alarm installation service covers all grades from residential Grade 2 systems through to commercial Grade 3 installations, with every system designed following a site survey and documented to the standard required for police and insurance registration.
What to Check Before Appointing an Intruder Alarm Company
Whether you’re appointing Cobra or any other security company in Hull and East Yorkshire, here’s what to verify before committing:
Check their SSAIB or NSI registration — Both bodies maintain a public register of accredited companies on their websites. Don’t just take a company’s word for it — look them up. An accredited company will be listed by name and will show their current certification status.
Check what standards they install to — Ask specifically whether they install to PD 6662:2017 and BS EN 50131. An accredited company should be able to answer this question clearly and without hesitation.
Ask about police registration — If you want police response to alarm activations, confirm that the company will register your system with the local police force and that they operate within the ACPO Security Systems Policy.
Ask about documentation — A proper installation should come with system documentation including a commissioning certificate, a system specification, and a user manual. If a company can’t provide these, that’s a significant red flag.
Check their complaints process — Ask what happens if you have a problem with the installation or ongoing service. An SSAIB accredited company will have a formal process. An unaccredited one may not.

Frequently Asked Questions
Both SSAIB and NSI are UKAS-accredited certification bodies for security and fire alarm companies in the UK, and both are accepted by insurers and the police. The main difference is organisational — NSI is slightly larger and covers a broader range of sectors. For most residential and commercial intruder alarm purposes, either certification is equally valid. What matters is that the company holds current, verifiable certification from one of the two bodies.
Many insurers do specify this as a condition of cover, but the requirement varies between policies. Check your policy documentation or call your insurer directly to confirm what they require. If your current system was installed by an unaccredited company, it’s worth finding out now rather than after a claim.
Under the ACPO Security Systems Policy, most UK police forces will only respond to activations from systems installed and maintained by NSI or SSAIB accredited companies. If your installer is not accredited, police response may not be available.
Yes. We regularly take over intruder alarm maintenance from other providers. We carry out an initial assessment to confirm the system grade and condition, advise on anything that needs attention to bring it up to standard, and then provide ongoing maintenance under our accreditation.
For SSAIB, visit ssaib.org and use their company search tool to verify current accreditation status by company name or location. For NSI, visit nsi.org.uk and use their approved company finder. Both searches are free and publicly available — always verify directly with the certification body rather than relying on a company’s own claims.
