Typical savings from running an IMS
Real numbers from IMSM clients who consolidated separate ISO management systems into one integrated framework.
IMS vs running separate ISO certifications
A simple side-by-side of what changes when you integrate.
| Separate ISO systems | Integrated Management System | |
|---|---|---|
| Documentation | Three or four separate manuals, each with its own policies and procedures. | One unified manual aligned to Annex SL — consistent terminology across all standards. |
| Audits | Separate audit cycles for each standard, often back-to-back disruption for the team. | One combined audit programme — less downtime, fewer days off the floor. |
| Internal effort | Duplicated processes, version-control headaches, conflicting requirements. | Shared controls, single risk register, one continual-improvement loop. |
| Cost over a 3-year cycle | Full surveillance + recertification fees per standard. | Special IMS pricing structures; lower combined audit fees through QAS International Ltd. |
| Governance | Information security may sit only with IT; H&S only with HR. | Controls applied company-wide — ISO/IEC 27001 obligations embedded everywhere. |
| Adding new standards | Each new standard is a fresh implementation project. | Annex SL makes new standards a bolt-on rather than a rebuild. |
How an IMS plays out by industry
Common combinations of ISO standards we integrate for clients in different sectors.
Manufacturing & engineering
Typical IMS: ISO 9001 + ISO 14001 + ISO 45001
One quality, environment and safety framework on the shop floor — useful for supplier audits, tender submissions and regulatory inspections in a single visit.
Tech & SaaS
Typical IMS: ISO 9001 + ISO/IEC 27001
Information security controls baked into the quality system, so engineering, support and sales all operate against the same governance, risk and compliance model.
Healthcare & life sciences
Typical IMS: ISO 9001 + ISO 14001 + ISO/IEC 27001
Patient data protection, quality of care and environmental controls under one auditable system — with clear evidence chains for regulators and commissioners.
Construction & facilities
Typical IMS: ISO 9001 + ISO 14001 + ISO 45001 + ISO 50001
Quality, environment, occupational safety and energy under one combined audit cycle — the integrated approach most public-sector tenders now expect.
What is Annex SL, and why does it make an IMS possible?
Annex SL is the high-level structure that every modern ISO management-system standard now follows. It defines 10 common clauses, identical core text, shared terms and shared definitions. That is what lets ISO 9001, ISO 14001, ISO 45001, ISO/IEC 27001 and ISO 50001 plug into a single management system rather than fighting each other.
The 10 Annex SL clauses are:
- Scope
- Normative references
- Terms and definitions
- Context of the organisation
- Leadership
- Planning
- Support
- Operation
- Performance evaluation
- Improvement
If you already hold one Annex SL-aligned standard, you have already done roughly 30-40% of the work for the next one. An IMS captures that shared work once, not three or four times.
More IMS questions, answered
What is Annex SL in plain English?
Annex SL is the shared blueprint every modern ISO management-system standard follows — same clause numbers, same terminology, same structure. It is what makes integration possible. You build the chassis once and bolt each standard onto it.
How much does an IMS cost?
It depends on which standards you integrate, how many employees and sites you have and how mature your existing systems are. Most clients pay materially less for a combined IMS than for the same standards run separately because audits, documentation and surveillance are consolidated. We will quote a fixed fee after a short scoping call.
Will my staff need to be retrained?
Usually no full retraining is needed. Because Annex SL aligns terminology across standards, staff who already know one standard pick up the rest very quickly. We provide a short awareness briefing as part of implementation.
Can I add a new ISO standard to my IMS later?
Yes — that is one of the strongest reasons to start with an IMS. New Annex SL-aligned standards bolt onto your existing framework rather than triggering a fresh implementation project, so you scale compliance without scaling overhead.
Does an IMS work for small businesses?
It is especially useful for smaller teams. Running several ISO systems in parallel is far more painful for a 20-person business than for a 2,000-person one. An IMS removes most of that admin load and keeps compliance proportionate to your size.
How long does implementation take with IMSM?
Most IMS projects with IMSM take 3 to 6 months end-to-end, depending on how many standards are in scope, your starting point and the size of the business. Our typical clients integrate two to three standards inside one engagement.
