Audit Services
Audits that prove you conform and help you improve.
An audit is an independent check of the way your organisation works. Ours does more than tick a box. We confirm you meet the standard, then show you where you are spending too much and where results fall short, so your management system starts paying for itself.
Independent and trusted
Impartial decisions in line with ISO/IEC 17021-1.
Sector qualified auditors
People who understand your industry and its risks.
Clear, useful reports
Findings ranked by priority with a plain path to fix them.
The idea in three words
What a good audit actually measures
Most audits stop at the first question. A valuable audit answers all three.
Conformity
Do you meet the requirements of the standard, such as ISO 9001, ISO 45001 or ISO 14001? This is the baseline every audit must confirm.
In plain terms: are you following the rules you signed up to?Efficiency
Is the way you work costing more time, money or effort than the result needs? We look for waste, duplication and controls that are heavier than the risk.
In plain terms: are you spending more than you should?Effectiveness
Is the system actually delivering the outcomes you want, such as consistent quality, safer work and fewer complaints? We check that your goals are being met.
In plain terms: is it giving you the results you wanted?Our Services
Audit services we provide
From your first readiness check to your certificate and beyond, pick the audit that fits where you are.
Gap analysis Start here
A readiness review that compares your current way of working against the standard. You get a clear list of what is missing before you invest in a full audit.
Internal audit
A self check we run on your behalf to find and fix problems early. It keeps your system healthy and prepares you to pass an external audit with confidence.
Certification audit
The formal, two stage audit that leads to your accredited ISO certificate. Stage 1 reviews your documents and readiness, Stage 2 confirms the system works in practice.
Surveillance and recertification
Short annual checks that keep your certificate valid, followed by full recertification in year three. They confirm your system stays effective over time.
The Process
How our audits work
Four clear steps, guided by ISO 19011, the international guideline for auditing management systems.
Scope and plan
We agree what will be audited, which sites are involved, and the risks that matter most, then share a simple plan.
Gather evidence
On site or remote, the auditor reviews records, talks to your team, and watches how work is really done.
Report findings
You receive plain language findings, ranked by priority, covering conformity, efficiency and effectiveness.
Improve and decide
You act on the findings. For certification, an independent decision confirms your certificate can be issued.

What to ask for in your audit plan
An audit you pay for should leave you with more than a pass or fail. Ask your auditor for all three of these.
- Written confirmation that your business conforms to the standard. This is the minimum any audit should give you.
- A view on efficiency: where a process is costing more time, money or effort than the risk and result require.
- A view on effectiveness: whether the system is meeting its goals and delivering the outcomes you set.

Questions
Audits, explained simply
What is an ISO audit?
An ISO audit is an independent check of the way your organisation works. An auditor gathers evidence and compares it against a standard, such as ISO 9001 or ISO 45001, to confirm your management system meets the requirements and is working in practice.
What is the difference between an internal audit and a certification audit?
An internal audit is a self check you run to find and fix gaps before an external audit. A certification audit is carried out by an independent certification body and, when passed, leads to an accredited certificate that customers and regulators can trust.
What do conformity, efficiency and effectiveness mean?
Conformity means you meet the rules of the standard. Efficiency means you are not spending more time, money or effort than the result requires. Effectiveness means the system actually delivers the outcomes you want, such as quality, safety or fewer complaints.
Which ISO standards does ACS-GP audit?
We audit common management system standards including ISO 9001 for quality, ISO 45001 for occupational health and safety, ISO 14001 for the environment, and others. Contact us to confirm your standard.
How long does an audit take and what does it cost?
Audit time depends on your organisation size, the number of sites, and the complexity and risk of your processes. Contact ACS-GP for a clear, tailored quotation with no obligation.
