THE GAP BETWEEN SUPPLIERS

Your contamination control strategy is only as strong as the suppliers inside it.

Garments from one company. Cleaning from another. Consumables from a third, training from a fourth. Each one meets its own specification and passes its own audit. None of them is accountable for how the four work together inside your gowning room.

You know this already. It's why supplier documentation is the first thing you check before an inspection, and the last thing that's ever ready.

cws-icon-evidence-1

Evidence you assemble, not evidence you have

Four suppliers, four documentation standards. Under Annex 1, the parts that sit with a supplier are examined as though they were yours - assembled while the inspector waits.

cws-icon-gaps

Gaps nobody is responsible for

A garment arrives validated. A wiper arrives certified. Whether they work together in your cleanroom sits between two contracts. Contamination doesn't respect a contract boundary.

cws-icon-continuity

Continuity set by your least-prepared supplier

One missing glove size can stop a line. When four suppliers forecast separately and none sees your usage, your weakest planner sets your continuity.

cws-icon-savings

Savings a single day can erase

A 15–25% cut on unit price reads as a win. One day of unplanned downtime, an estimated €68,000 to €228,000, erases two to five years of it.

Four years of procurement savings, against one day of unplanned downtime

Illustrative: a 20% unit-price saving on a €225,000 annual spend, accumulated quarterly, then set against the estimated cost of a single disruption.

Fragmenting your supply base to reduce cost doesn't remove the risk.
It moves it to the one function that can least afford to carry it: yours.

INTEGRATED CLEANROOM MANAGEMENT

All five, run as one programme. One organisation accountable for the whole of it.

CWS Cleanrooms runs textiles, cleaning, consumables, training and on-site support as a single validated programme. Same quality system, same evidence standard, across nine European facilities. You stop coordinating suppliers and start managing one relationship;

cws-textiles-optical

Textiles

Cleanroom garments, laundered and validated to the same standard every cycle.

cws-cleaning-optical

Cleaning

Trained operators working to your SOPs, with documentation that survives audit.

cws-consumables-optical

Consumables

Gloves, wipes, garments and disinfectants supplied as a managed programme - buffered, forecast with you, and certified online.

cws-training-optical

Training

Role-based cleanroom training for operators, cleaners and supervisors, mapped to the standards you're audited against.

cws-onsite-optical

On-site service

Airlock stocking and day-to-day cleanroom logistics, run by our people on your site.

Integrated Cleanroom Management

Run any combination of the five as one coordinated programme with a single point of accountability, one quality system, and  one set of reporting.

WHERE THE RISK SITS

Which risks stay yours. Which become ours.

Consolidating suppliers should never mean losing control of your quality system. It means moving the operational risk you're allowed to delegate, and keeping the accountability you aren't. Most suppliers describe themselves as partners. Fewer will publish which risks they take on, because publishing it means being held to it.

You own

  • Your contamination control strategy, and every decision inside it.
  • Your cleanroom classification, SOPs and release criteria.
  • Final QA approval, and your relationship with your inspector.

We own

  • Validated decontamination and sterilisation, revalidated annually against three test organisms to a minimum reduction of seven log stages.
  • Garment availability, item-level traceability, and enforced maximum wash counts.
  • Consumable buffer stock, joint forecasting, and certificates available 24/7.
  • Operator and cleaner competency — trained, tested and documented per person.
  • Supplier-side audit evidence, prepared before the inspection rather than assembled during it.

Shared

  • An annual risk review, QA to QA.
  • Demand planning and change control.
  • Deviation investigation, when something does go wrong.
The risk that used to sit with you now sits with us.

WHERE TO BEGIN

Most conversations start with one pressing problem. Start with yours.

“We want all of it under one contract.”

One programme across all five services, one contact, one standard, one set of data.

“We're seeing contamination events.”

There are five routes contamination takes into a cleanroom. We close each one, and show you how.

“We can't afford to stop.”

Buffer stock, forecasting done with you, and nine European facilities running one quality system.

“An inspection is coming.”

Get the supplier-side evidence in place before an inspector asks for it. Annex 1 sections 2.5, 7.4 and 7.11–7.17, covered.

BUILT FOR YOUR REGULATORY WORLD

We speak the standard you're audited against.

cws-icon-pharmaceutical

Pharmaceutical manufacturing

Since the 2023 revision, an inspector treats your garment programme as a qualified GMP process. We run it that way — Grade A/B, and Annex 1 sections 7.11–7.17 evidenced as a matter of course. Including biologics, vaccines, cell and gene therapy, generics and CDMOs.

cws-icon-medical-device
 

Medical device manufacturing

Your garments, cleaning and gowning competency are outsourced processes inside your ISO 13485 system and your MDR technical documentation. A notified body can audit them, unannounced. We make sure they hold up.

cws-icon-semiconductor

Semiconductor manufacturing

A defect far below a micron is enough to scrap a die, and garments are a contamination source you buy rather than engineer. Validated for ISO 4 at rest and ISO 5 in operation, with electrostatic control built in.

THE DIFFERENCE, MEASURED

The results.

HOW WE WORK

Who you'd be working with.


Specialists, not generalists

Everyone on your account works in cleanrooms and nothing else. 1,650+ people, 40+ years, one field. You won't be explaining what Grade B means.


Evidence over opinion

We test claims before we make them. Every product and process is validated against a named standard, not described with an adjective.


Problems solved together

When your site doesn't fit the standard programme, we build around it with you. There's no script for that conversation, and no call centre at the end of it.

MAKING THE CHANGE

Live in as little as 43 days.

The reason most sites keep four suppliers isn't that they prefer it. It's that changing looks like a validation exercise nobody has time for. We run the transition, your documentation stays continuous throughout, and your team keeps working.

  1. 13-25 days

    Assess, agree, contract

    We assess your current programme, agree scope and standards, and put the contract in place.

  2. 30-60 days

    Specify, stock, train

    Garment sizing and specification, stock build, operator training, and your documentation transferred without a gap.

  3. Ongoing

    The programme runs

    Quarterly review, annual risk review, one contact throughout.
