NQA is a UK-based, UKAS-accredited certification body providing ISO management system certification to organisations in the UK and internationally. NQA is widely recognised for its technical depth, auditor competence and strong presence in regulated and risk-critical sectors, while still supporting SMEs and first-time ISO adopters.
NQA is commonly selected where certificate credibility, sector expertise and audit rigour are prioritised, including in aerospace, automotive, engineering, construction, IT, healthcare and public-sector supply chains.

What NQA does
NQA provides third-party, independent certification audits against internationally recognised ISO management system standards. Its role is to assess whether an organisation’s management system conforms to the relevant standard and, where applicable, issue UKAS-accredited certificates.
NQA’s activities include:
- Initial certification audits
- Annual surveillance audits
- Recertification audits (typically every three years)
- Integrated management system audits
NQA does not develop or publish ISO standards and does not act as a National Standards Body. ISO standards must be purchased separately from authorised publishers.
ISO standards commonly certified
NQA maintains a broad UKAS accreditation scope, making it suitable for both general and sector-specific certification needs. Common standards include:
- ISO 9001 – Quality management systems
- ISO 14001 – Environmental management systems
- ISO 45001 – Occupational health and safety
- ISO 27001 – Information security management systems
- ISO 22301 – Business continuity management
- ISO 50001 – Energy management systems
- ISO 20000-1 – IT service management
In addition, NQA is often used for sector-specific or higher-risk schemes, subject to scope and accreditation.
UKAS accreditation and credibility
Why UKAS matters
In the UK, UKAS accreditation is the accepted benchmark for ISO certificate credibility. Many public-sector bodies, infrastructure operators and regulated supply chains explicitly require UKAS-accredited certification.
NQA’s accreditation position
NQA operates as a UKAS-accredited certification body across a defined range of standards, sectors and activities. As with all certification bodies:
- Accreditation is standard-specific
- Sector codes and risk classifications apply
- Scope must be confirmed before certification
NQA is frequently chosen where procurement or regulatory scrutiny is high.
Typical ISO certification process
NQA follows the standard UKAS-aligned ISO audit lifecycle:
- Initial enquiry and scoping – sites, headcount, risk and scope defined
- Quotation and application – audit programme and cycle agreed
- Stage 1 audit – readiness and system design review
- Stage 2 audit – full conformity assessment
- Certification decision – certificate issued if compliant
- Surveillance audits – normally annual
- Recertification audit – usually every three years
NQA is generally regarded as applying a structured, evidence-based audit style, particularly valued in technical and regulated sectors.
Integrated management systems
NQA regularly audits integrated management systems, allowing organisations to combine multiple standards into a single audit programme, such as:
- ISO 9001 + ISO 14001
- ISO 9001 + ISO 45001
- ISO 9001 + ISO 14001 + ISO 45001
Benefits typically include:
- Fewer audit days overall
- Lower total certification costs
- Reduced operational disruption
This approach is common among construction, manufacturing and engineering clients.
Pricing and market positioning
NQA does not publish fixed ISO certification price lists. Typical characteristics of its pricing and positioning include:
- Mid-range to upper-mid pricing compared with SME-focused providers
- Audit-day based pricing models
- Competitive value for complex, multi-site or regulated scopes
- Less emphasis on discount-led sales, more on audit competence
For very small organisations seeking the lowest possible cost, NQA may not be the cheapest option; for organisations needing credible, defensible certification, it is often considered good value.
Who typically chooses NQA?
Engineering and manufacturing
- Strong alignment with quality, safety and environmental controls
- Suitable for safety-critical and process-driven operations
Construction and infrastructure
- ISO 9001, ISO 14001 and ISO 45001 combinations
- Framework and tender-driven certification requirements
IT and information security
- ISO 27001 and ISO 20000-1
- Complex scopes involving cloud services and data processing
Healthcare and regulated supply chains
- High expectations around audit depth and traceability
Public-sector suppliers
- Mandatory UKAS-accredited certification
- Procurement scrutiny of certification bodies
How NQA compares with other certification bodies
In the UK ISO certification market, NQA is generally perceived as:
- More technically rigorous than purely SME-focused providers
- Comparable to ISOQAR in audit depth and regulated-sector suitability
- Less globally diversified than SGS, but more focused on ISO certification
- Less consumer-brand oriented than BSI, but strong on audit credibility
This positions NQA well for organisations where audit robustness matters more than brand visibility.
