The ISO 9001 accreditation scheme is an internationally recognised standard for quality management systems (QMS).
It provides a framework for organisations to ensure they consistently meet customer and regulatory requirements and demonstrate continuous improvement. ISO 9001 certification signifies that SJG Electrical & Security has robust processes in place for quality control, risk management, and customer satisfaction
The NSI Gold mark is recognised as a hallmark of excellence in the industry, indicating that a company operates to the highest standards of security and fire safety.
SJG Electrical & Security undergo rigorous and regular audits to ensure ongoing compliance with the required standards. This means customers can trust that the systems installed and maintained by us are of the highest calibre, offering enhanced security and peace of mind. View the certification
The BAFE Fire Safety Register scheme is a certification programme in the United Kingdom that ensures companies involved in fire protection services meet high standards of competency and reliability.
By adhering to stringent criteria and regular assessments, SJG Electrical & Security earn BAFE approval, signifying their compliance with industry best practices and regulations. This provides assurance of quality, expertise, and adherence to legal requirements in fire safety. View the certification
The National Inspection Council for Electrical Installation Contracting (NICEIC) is a UK-based regulatory body that oversees the work of electrical contractors to ensure they meet strict safety and quality standards.
Using SJG Electrical & Security a NICEIC-approved company benefits customers by providing assurance that the work carried out complies with the highest industry standards, reducing the risk of electrical faults and enhancing overall safety.
The benefits of using an MCS certified installer.
If you are interested in generating your own energy, it is important to use an MCS certified Installer so that the technology you choose is specified, installed and maintained correctly.
MCS is a mark of quality. Using an MCS certified installer ensures that equipment meets good standards of performance and that installers are technically safe and competent.
MCS certified Installers have undergone a rigorous vetting process to demonstrate that they adhere to our Standards. These Standards demonstrate a commitment to quality. They will also be a member of a Consumer Code which means strengthened customer protection for you.
Accreditation FAQ’s
1. What is the practical significance of holding multiple accreditations such as NICEIC, NSI Gold, and BAFE, and how do they interact?
Holding multiple third-party accreditations demonstrates a layered and discipline-specific approach to compliance, rather than reliance on a single overarching certification. Each scheme governs distinct technical domains:
- NICEIC validates electrical installation competence, ensuring work complies with BS 7671 (IET Wiring Regulations) and associated statutory frameworks such as the Electricity at Work Regulations 1989.
- NSI Gold combines ISO 9001 quality management with rigorous sector-specific auditing for security systems (intruder alarms, CCTV, access control), including operational performance, staff vetting, and system design compliance (e.g. PD 6662).
- BAFE Fire Safety Register focuses on fire detection, alarm systems, and fire protection services, verifying competency against standards like BS 5839 and BS 5266.
From a technical procurement perspective, these accreditations are complementary rather than redundant. For example, an integrated project involving fire alarms, access control, and electrical infrastructure requires compliance across all three domains. Multi-accreditation ensures that each subsystem is designed, installed, and maintained under the correct regulatory framework, reducing risk exposure and ensuring audit traceability.
2. How does ISO 9001 certification influence the quality and consistency of electrical and security installations?
ISO 9001 is a process-driven Quality Management System (QMS) standard that governs organisational workflows rather than technical outputs directly. Its value lies in enforcing:
- Documented procedures for design, installation, commissioning, and maintenance
- Corrective and preventive action mechanisms (CAPA) for non-conformities
- Internal auditing and continuous improvement cycles
- Supplier and subcontractor control
In practical terms, ISO 9001 ensures that electrical and security installations are not only compliant at the point of delivery but are delivered through repeatable, controlled processes. For example:
- Installation checklists aligned with BS standards are consistently applied
- Test and inspection records are uniformly documented and retrievable
- Staff competency and training are tracked systematically
For commercial clients, this reduces variability between projects and ensures a predictable standard of workmanship, particularly important in multi-site or framework contracts.
3. What does the NICEIC accreditation specifically guarantee in terms of electrical safety and compliance?
NICEIC (National Inspection Council for Electrical Installation Contracting) accreditation provides third-party verification that a contractor is competent to undertake electrical work in accordance with UK regulations.
Key technical assurances include:
- Compliance with BS 7671 (18th Edition Wiring Regulations, including amendments)
- Proper execution of initial verification and periodic inspection & testing (EICR)
- Correct use of protective devices, earthing arrangements, and circuit design calculations
- Adherence to Part P of the Building Regulations (where applicable)
NICEIC-approved contractors are subject to regular audits, including on-site inspections of completed work. This ensures that:
- Test instruments are calibrated and used correctly
- Certification (EIC, Minor Works, EICR) is accurately completed
- Installations meet both safety and functional requirements
For businesses, this translates into reduced liability, especially in environments with high electrical demand or public access.
4. What is the difference between NSI Gold and other security certifications, and why is it considered a higher standard?
NSI Gold is widely regarded as the highest tier of certification within the UK security industry because it integrates:
- ISO 9001 Quality Management System compliance
- Sector-specific technical standards for security systems
This dual-layer certification means that a company is assessed on both how it operates (quality management) and what it delivers (technical compliance).
Key technical elements assessed include:
- System design in accordance with standards such as PD 6662, BS EN 50131 (intruder alarms), and BS EN 62676 (CCTV)
- Alarm signalling and monitoring compliance (e.g. ATS categories)
- Staff screening to BS 7858
- Installation, commissioning, and maintenance protocols
Compared to lower-tier or single-scope certifications, NSI Gold requires ongoing surveillance audits and more stringent documentation controls. For commercial clients, particularly in regulated sectors (e.g. finance, critical infrastructure), it provides assurance that systems will meet insurer and police response requirements.
5. How do MCS and EV (Electric Vehicle) accreditations such as iCS relate to sustainability and future-proofing infrastructure?
MCS (Microgeneration Certification Scheme) and EV-related accreditations (e.g. iCS for EV charging installations) are critical for organisations investing in low-carbon technologies.
From a technical standpoint:
- MCS ensures that renewable energy systems (e.g. solar PV, heat pumps) are designed and installed in accordance with performance and safety standards. This includes correct system sizing, inverter selection, and grid integration.
- EV charging accreditations validate competency in installing charge points compliant with standards such as BS 7671 Section 722 and relevant IET Codes of Practice.
These certifications also ensure:
- Eligibility for government incentives or grants (where applicable)
- Proper load management and electrical capacity assessments
- Integration with smart systems (load balancing, demand-side response)
For businesses, the key benefit is infrastructure resilience. Properly accredited installations mitigate risks such as:
- Overloading existing electrical systems
- Non-compliance with DNO (Distribution Network Operator) requirements
- Inefficient energy utilisation
