GMP Certification
GMP assessment examines whether manufacturing is genuinely controlled — hygiene, documented procedures, trained people, maintained equipment and traceable product.

The standard
Overview
Good Manufacturing Practice is the discipline of making products under controlled, documented and repeatable conditions. A GMP assessment looks at the whole production environment: the facility and how it is kept, the equipment and how it is maintained and calibrated, the procedures staff actually follow, the training records behind them, the controls on materials and suppliers, and the traceability that connects a finished batch back to its inputs.
GMP matters wherever product quality and safety depend on how something is made rather than only on how it is tested at the end — food and beverage production, cosmetics, supplements, packaging and other consumer products. Customers and retailers ask for GMP evidence because it answers a question a certificate of analysis cannot: is the next batch going to be made the same way?
UKCert assesses your practices against a documented GMP framework agreed at scoping, appropriate to your sector. We examine the operation in production, interview operators and supervisors, trace batches through the records and report findings in plain English against the specific control concerned. The certification decision is taken independently of the audit team.
Who this is for
- Food, beverage and supplement manufacturers
- Cosmetics and personal care producers
- Contract manufacturers and co-packers
- Packaging producers supplying food or personal care brands
- Manufacturers asked for GMP evidence by retail or export customers
- Operations formalising controls ahead of ISO 9001 or ISO 22000
What it gives you
Why organisations certify
What a certified GMP assessment gives you once the certificate is issued.
Consistent manufacturing practice
Documented procedures, defined responsibilities and checked records mean the product is made the same controlled way on every shift, not just when the right person is in.
Hygiene and facility control
Cleaning schedules, zoning, pest control and maintenance are assessed as systems with records, not as a walk-round impression on the day.
Equipment you can rely on
Maintenance, calibration and change control keep equipment producing within specification, with the records to prove when it was last checked and by whom.
People who know the procedure
Training and competency records connect each controlled task to the people performing it, so a procedure on paper is also the procedure in practice.
Traceability in both directions
Batch records connect finished product back to materials, equipment and operators — and forward to customers — so an issue can be isolated quickly and narrowly.
Supply-chain confidence
Independent GMP certification gives retailers, brands and export customers documented assurance about how the product is made, ahead of their own audits.
Scope
What the assessment covers
The areas an assessor works through. Your final scope is confirmed in writing before any audit is booked.
- Production and process controls
- Hygiene, cleaning and sanitation programmes
- Facility zoning, layout and maintenance
- Equipment maintenance, calibration and change control
- Documented procedures and batch records
- Staff training and competency records
- Material, supplier and storage controls
- Traceability and recall arrangements
- Quality control checks and release
How it runs
The assessment, stage by stage
From first enquiry to certificate. Each stage is agreed with you before it starts.
-
Scope and quotation
We agree the products, processes, sites and the GMP framework the assessment will reference, then quote against that written scope.
-
Documentation review
A review of your procedures, batch documentation, training matrix and hygiene programmes, identifying anything missing before the site assessment.
-
Site assessment
We assess the operation in production: hygiene and facility condition, equipment records, adherence to procedure at the line, and batch traceability exercised end to end.
-
Findings and close-out
Findings are reported against the specific control concerned, with correction and root cause evidenced on an agreed timescale.
-
Certification and surveillance
An independent reviewer takes the certification decision. Surveillance during the cycle confirms the controls remain in place and in use.

Certifying against more than one standard?
Where you hold several standards, shared clauses are assessed once in a combined visit rather than as separate audits. Talk it through with an assessor before you decide what GMP should sit alongside.
