If you are choosing a security company for your home or business, you may have come across the term NSI Gold approved. But why does it matter who you choose and what difference does it actually make?
When it comes to protecting your property, not all security companies operate to the same standard. This is where NSI Gold certification becomes an important factor in your decision.
Understanding NSI Gold Certification
NSI (National Security Inspectorate) is one of the United Kingdomโs leading independent security certification bodies, and Wilson Alarms are proud to uphold their highest Gold standards.
NSI Gold certification is awarded to companies that meet strict industry standards for the design, installation and maintenance of security systems. To achieve it, businesses must also operate under the internationally recognised ISO 9001 quality management standard.
In simple terms, it means the company has been independently assessed and proven to work to a consistently high level.
Why It Matters When Choosing a Security Company
Choosing an NSI Gold approved security company such as Wilson Alarms is not just about accreditation, it is about confidence in the service you receive.
โ๏ธ Not all security companies are independently assessed
Unlike non accredited providers, NSI Gold approved companies are regularly audited to ensure they continue to meet strict standards. The differences in quality, process and accountability can be significant.
โ๏ธ Proven quality and consistency
From system design through to installation and maintenance, every step our security engineers take is checked against recognised industry standards. This helps ensure your new security system performs reliably when you need it most.
โ๏ธ Professional standards you can trust
NSI approved security companies must follow a strict Code of Ethics, covering:
- Honest and transparent advice
- Fair dealing with customers
- High standards of workmanship
- Competent, trained engineers
โ๏ธ Reduced risk and greater peace of mind
Because every NSI Gold approved company is independently assessed, you can be confident that an installation by Wilson Alarms has been carried out correctly and professionally.
โ๏ธ Recognised certification for insurance
After installation, you will receive an NSI Certificate of Compliance, which is often required by insurance providers as proof your security system meets industry standards.
