Theatre Badge Hats are reusable theatre uniform, the regulatory equivalent of scrubs. They are not classified as medical devices, and we don't claim them to be. What we do is invest in independent validation through the institutions that genuinely matter for NHS theatre use: engineering bodies, university materials research hubs, NHS-trust expert reviews, and the industrial laundries that actually process theatre wear day to day.
This page sets out who has tested what, what the evidence actually shows, and how each piece of validation maps to the specific question it answers. Every test report referenced below is available as a direct PDF download. Documentation packs for NHS Trust due diligence are sent the same working day on request.

Badge fastening system: TWI Cambridge
The detachable badge is the design choice that makes named, reusable caps practical at the scale of a Trust establishment. Embroidered names turn every role change, staff departure, or sizing variation into a re-order; the detachable approach solves all of that, because the cap stays the same and the badge changes. But it only works if the fastening system genuinely withstands repeated use.
To establish that, we commissioned TWI Cambridge, one of the world's leading independent research and technology organisations, used by government, defence, aerospace, and medical-device industries for materials testing and engineering validation.
Three clinical hats, each with a fastening system, mounted in a mechanical test machine. The badges were removed and reattached using the peel technique most commonly observed in real users, one stainless steel press stud at a time. Each cap and badge combination was subjected to 400 separation and reattachment cycles, with peel load recorded at each point.
"The supplied badge and hat fastening system is capable of a minimum of 400 peel separations and re-attachments and still performs as designed. The materials supplied (hat, badge, fasteners) do not wear or change appearance when subjected to 400 separation/re-attachment tests. The system is suitable for its designed use as a clinical hat with removable ID badge."
Badge chemical resistance: AMCASH, University of Birmingham
The detachable badge is cleaned between uses. For most everyday use that's soap and water in the changing room. But where a Trust's IPC policy requires more rigorous disinfection (using clinical cleaning agents), the question of how the badge holds up matters.
We commissioned AMCASH (Advanced Materials Characterisation and Simulation Hub) at the University of Birmingham, a university-led materials research facility, to test the badges against the three clinical cleaning agents most commonly used in NHS theatre environments.
Twelve polyester-based badges tested in four groups: control, 70% IPA (Medisanitize), Actichlor (NaDCC/chlorine, 1000ppm available Cl₂), and Clinell (benzalkonium chloride / DDAC / PHMB). Each test group exposed continuously for 25 hours on an orbital shaker, equivalent to one year of twice-daily clinical cleaning. Tensile strength tested pre and post-exposure on an Instron 5566 mechanical tester.
"No significant difference was detected in terms of tensile strength between the control group and the chemically treated badges. The mechanical performance of the badges did not deteriorate due to exposure in the cleaning solutions. No damage was observed on the metallic popper fastening system." Visual caveat: 70% IPA caused visible warping of the badge fabric (strength was maintained but appearance was affected).
The badges also carry an existing accreditation for 50+ industrial washes at 95°C with tunnel finishing as part of the flame-retardant and anti-static garment standard they're produced to. This is a more severe protocol than the everyday soap-and-water cleaning, and goes well beyond what real-world use requires.
Expert clinical review: DEMAND Hub & University Hospitals Birmingham
Engineering and materials tests answer specific physical questions about the product. They don't answer the broader clinical question that NHS IPC teams ask first: does this product work safely in real NHS theatres, processed through real NHS systems, used by real NHS staff?
To address that, we commissioned the DEMAND Hub (Data-Enabled Medical Technologies and Devices), a strategic partnership between the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust, funded under the European Regional Development Fund, to conduct an independent expert clinical review of the reusable cloth hat system.
Dr Gillian McNab convened seven senior NHS clinicians from five Trusts (University Hospitals Birmingham, Northampton General, NHS Fife, Coventry & Warwickshire, and Liverpool). Participants included an anaesthetist, an ODP, a matron in theatre and recovery, a sustainability manager, a senior ODP, a clinical procurement lead for theatres, and a lead midwife. Each had implemented or was planning to implement reusable cloth caps. The review covered original objections, IPC team engagement, washing protocols, infection rate concerns, cost analysis, lifespan expectations, team interaction effects, and downsides. Dr Ts'ong Sui simultaneously conducted a literature review on published research comparing infection rates between cloth and disposable hats.
Independent, multi-Trust clinical validation that reusable cloth hats can be implemented safely within NHS IPC frameworks, alongside a published literature review of the infection-rate evidence base. The reviewers' practical insights on washing protocols, IPC engagement, and team adoption are the substantive procurement-relevant content here.
The DEMAND Hub report is an expert clinical review and literature review, multi-Trust qualitative validation by senior NHS clinicians, plus a published infection-rate literature review. It is not a quantitative antimicrobial laboratory test (e.g. ISO 20743 or ISO 22196). We're explicit about this because Theatre Badge Hats are reusable theatre uniform, the same category as scrubs, and antimicrobial certification testing applies to products making antimicrobial claims, which we don't.
Industrial laundering: Elis, Johnsons Workwear, Rocliff & Synergy
The most important real-world question for IPC sign-off isn't whether the cap survives a laboratory test, it's whether it survives the actual industrial laundering processes used by NHS Trusts. We've answered that question by putting Theatre Badge Hats through processing at four of the leading UK healthcare and workwear laundries:
- Elis, one of the largest healthcare and workwear laundry operators in Europe, with extensive NHS contracts
- Johnsons Workwear, major UK industrial laundry serving healthcare and workwear contracts
- Rocliff, UK industrial laundry with experience in healthcare textile processing
- Synergy, UK healthcare laundry specialist
Each laundry has independently confirmed in writing that Theatre Badge Hats are suitable for central laundering, wash and dry effectively, and do not tangle or stick together in commercial laundry equipment. These are the same operators that already process scrubs and theatre wear for NHS Trusts day in, day out, which means the question of "will this cap survive our laundry contract?" is already answered for any Trust using one of the four. Written confirmations available on request to NHS Trust IPC and procurement teams.
How the cap and badge are cleaned
The hat and the badge follow different cleaning protocols by design, because they're different kinds of object. Industrial laundering is appropriate for the fabric hat; soap and water is appropriate for the rigid badge.
The hat
The hat is constructed from 145gsm polyester-cotton blend (65/35), a standard NHS healthcare textile specification. It is processed through hospital industrial laundering, alongside scrubs and other theatre wear, at standard NHS thermal disinfection temperature (typically 70°C). Drying is per the laundry provider's standard practice for theatre wear. The hat is designed for a working life of 3+ years in standard NHS theatre use, consistent with the typical savings comparison against disposable caps.
The badge
The badge is detached from the hat before laundering. Everyday cleaning is soap and water in the changing room, between uses, by the user (the same approach used for ID lanyards and similar shared clinical-environment items). Where a Trust's IPC policy requires more rigorous disinfection (using Actichlor, Clinell, IPA or similar), AMCASH testing has confirmed the badge withstands the equivalent of one year of twice-daily clinical disinfectant cleaning without loss of tensile strength.
This separation is deliberately designed to minimise IPC complexity. The hat goes through the same laundry process as scrubs. The badge, which would otherwise be a rigid component cycling through industrial laundering, is cleaned through the same simple process used for other reusable clinical-environment items.

ISO 9001: Quality management
Eco Ninjas Ltd operates a quality management system certified to ISO 9001, the international standard for quality management.
- Certifying body: British Assessment Bureau (BAB), UKAS-accredited
- Certificate number: 265960
- Status: Current and in-date, renewed annually via surveillance audit
ISO 9001 certification means our quality management processes (including supplier management, document control, complaint handling, corrective action, and continuous improvement) are documented, audited, and operating to international standard. It's a system-level certification of how we run, not a product-level test.
We do not currently hold ISO 14001 (environmental management system certification). We have prioritised ISO 9001 first because it most directly relates to product quality and customer accountability.
Life Cycle Assessment: planned
A reusable cap replaces a recurring stream of disposables. The environmental case for the switch only holds if the lifecycle impact of manufacture, laundering, and end-of-life is genuinely lower than the disposables it displaces. The most credible answer to "by how much, on what basis, calculated by whom?" comes from an independent Life Cycle Assessment.
A formal LCA conducted to ISO 14040 (principles and framework) and ISO 14044 (requirements and guidelines) is planned. The LCA will provide independently calculated cradle-to-grave environmental data, covering raw materials, manufacturing, transport, use-phase laundering, and end-of-life, compared against a baseline NHS disposable theatre cap.
Our environmental figures use industry-standard methodology drawing on published lifecycle data for comparable reusable healthcare textiles. We've chosen to be explicit about this rather than imply we already hold an independent LCA. Our published Carbon Reduction Plan (PPN 06/21-aligned) sets out our Scope 1, 2 and 3 baseline emissions and our committed reduction pathway to Net Zero by 2045.
For our sustainability framework including Greener NHS alignment, the Design for Life Roadmap, and our published Carbon Reduction Plan, see our page for sustainability leads.
IPC clearance at NHS Trusts
NHS Infection Prevention and Control governance is local. Every Trust has its own IPC team and its own clearance process, there is no single national "approval" body for theatre uniform. The relevant credibility signal is whether the product has been cleared by real Trust IPC teams in practice.
Theatre Badge Hats have been cleared through IPC processes at NHS Trusts across the UK. Somerset NHS Foundation Trust adopted the hats in the Trauma & Orthopaedics team at Musgrove Park Hospital, with Trust-wide rollout to all operating theatres in progress (see the Somerset case study for the full implementation account, including the rise in staff recognition from 41% to 96% within the first month). Great Western Hospital has introduced the hats in their maternity unit. The work was featured by BBC News in May 2026. Further NHS Trusts are currently approving the product as part of pre-purchase review.
What we don't claim
In the interest of being straight with reviewers, IPC teams, and procurement leads:
- Theatre Badge Hats are not medical devices. They are reusable theatre uniform, the regulatory equivalent of scrubs. We don't make MHRA medical-device claims and we don't carry MHRA medical-device classification.
- We don't make antimicrobial claims. Theatre wear sits within the IPC framework as a launderable garment processed at standard thermal disinfection cycles. Antimicrobial certification testing applies to products making antimicrobial claims, which we don't.
- We don't currently hold ISO 14001. Our environmental management is not yet third-party certified.
- We don't yet have a completed independent LCA. One is planned; until it's delivered, our environmental figures use industry-standard methodology, clearly stated as such.
- HTM 01-04 is a laundry-process standard, not a product certification. The accurate position is that Theatre Badge Hats are compatible with HTM 01-04-compliant processing, confirmed by industrial laundering at the four laundries above.
If the reviewer at your Trust is looking for a supplier that's transparent about what's evidenced and what isn't, that's us.

Frequently asked questions
Are Theatre Badge Hats classified as medical devices?
No. They are reusable theatre uniform, the regulatory equivalent of scrubs. They are not classified as medical devices and we do not make medical-device claims. The independent testing we hold is best-practice product validation for healthcare textiles, which is the appropriate framework for this product category.
Why is there no antimicrobial test report in the testing portfolio?
Antimicrobial certification testing (e.g. ISO 20743 or ISO 22196) applies to products making antimicrobial claims, which we don't make. Theatre wear sits within the IPC framework as a launderable garment processed at standard thermal disinfection cycles, alongside scrubs. The relevant validation for this product category is what we have: badge fastening durability (TWI), badge chemical resistance to clinical cleaning agents (AMCASH), real-world processing at NHS laundries, and independent expert clinical review by senior NHS clinicians (DEMAND Hub).
Why have you used real industrial laundries rather than a textile testing lab?
Because the question that matters for NHS procurement isn't "will it survive a lab simulation?", it's "will it survive the actual industrial laundering processes used by NHS Trusts?" Putting the product through Elis, Johnsons Workwear, Rocliff and Synergy answers that question directly, at the facilities that already hold NHS contracts.
How long does a Theatre Badge Hat last?
The hat is designed for a working life of 3+ years in standard NHS theatre use, consistent with the savings calculations on our Cost & Carbon Calculator.
What happens to the badge during laundering?
The badge is removed from the hat before laundering and cleaned separately. Everyday cleaning is soap and water in the changing room. Where a Trust's IPC policy requires more rigorous disinfection (Actichlor, Clinell, IPA), AMCASH testing has confirmed the badge withstands the equivalent of one year of twice-daily clinical disinfectant cleaning without loss of tensile strength.
Do you hold ISO 14001?
Not currently. We hold ISO 9001 (BAB / UKAS-accredited, certificate 265960). We have prioritised ISO 9001 first because it most directly relates to product quality and customer accountability.
Do you have a Carbon Reduction Plan?
Yes. Our Carbon Reduction Plan is published, PPN 06/21-aligned, prepared by The Carbon Stamp, and sets out our baseline emissions (423.66 kg CO₂e), 50% reduction target by 2035, and Net Zero target by 2045, in alignment with the NHS Net Zero Supplier Roadmap.
Do you have a completed Life Cycle Assessment?
Not yet. A formal LCA to ISO 14040/14044 is planned. Until commissioned and completed, our environmental figures use industry-standard methodology drawing on published lifecycle data for comparable reusable healthcare textiles.
Can we see the full test reports?
Yes. All test reports are available as direct PDF downloads from this page. For NHS Trusts requiring a bundled documentation pack alongside governance documents, email us and we'll send the full pack the same working day.
Are you registered with MHRA?
No, and we don't need to be. Theatre Badge Hats are not medical devices.
