Refillable certified standard

Refillable Certified verifies product systems that may help reduce negative environmental impacts through being refilled and reused multiple times.

Not all refillable product systems represent the same level of sustainability benefits. This Standard helps consumers identify products assessed against criteria underpinned by consumer data, giving them confidence they are choosing systems that may help reduce negative environmental impacts when compared with single-use equivalents.

• Use our Eligibility Checker to understand whether your refillable product system may be suitable for certification.
• The Eligibility Checker provides indicative guidance only and is not a certification decision.
• If your product appears ineligible, we still encourage you to contact us to discuss your product and future certification opportunities.

Eligibility Checker

Due to the use of a specially developed refillable eligibility scanning tool (REST), each refillable product system will go through a number of calculations and checks. This makes it difficult to state exactly what products need to have in order to be eligible, however we have a simple checklist below to help you identify if your refillable product system may pass all the eligibility requirements.

• Is the refillable product system for refill at home?
• Is the product listed within the table of eligible product types and subtypes?
• Does the product system contain a keeper container and an auxiliary unit?
• Are the materials used for the keeper container and auxiliary unit listed on the assessed material library?
• Has the keeper container and component parts, such as trigger sprays or pump dispensers, been tested for durability?
• Are the products sold in the UK, EU or US?

If you have answered yes to the above, then please reach out to find out more about certification. If you answered no to some of the above, please still get in touch to discuss your requirements and any potential next steps.

What You’ll Need to Provide

Brands applying for certification will be asked to submit:

• Product and packaging specifications
• Bill of Materials (BOM)
• Packaging weights and material composition data
• Durability and performance testing evidence
• Consumer use data (where applicable)
• Supporting technical documentation and declarations

The Certification Body will maintain confidential records of all data under the audit agreement.

What the Certification Body Will Assess

An approved Certification Body will review:

• Product eligibility against the Standard requirements
• Supporting evidence and technical documentation
• Packaging durability and performance data
• Material composition and environmental impact information
• Consumer use assumptions and supporting evidence

How the REST Tool Supports Certification

The Refillable Eligibility Scanning Tool (REST) is used during the certification assessment to evaluate the environmental performance of a refillable system.

The REST tool:

• Uses product, packaging and Bill of Materials (BOM) data
• Calculates key environmental impact indicators
• Determines the product’s Minimum Uses For Impact
• Compares the calculated MUFI against the required certification threshold

Understanding MUFI

• MUFI represents the minimum number of refill uses required for a refillable system to deliver environmental benefits compared to a single-use alternative.
• Certification eligibility is assessed against a MUFI threshold derived from consumer behaviour research.
• Products must have a calculated MUFI equal to or lower than the MUFI threshold to be considered for certification.

Certification Process

1. Check your product’s eligibility.
2. Reach out to the Certification Body for pre audit checks.
3. Submit your application and supporting evidence.
4. Certification Body conducts the technical assessment.
5. REST tool calculations are completed.
6. MUFI threshold requirements are assessed.
7. All documents are reviewed for compliance.
8. Certification Body submits its recommendation.
9. Circular Living Standards reviews the assessment outcome.
10. Certification licence and mark usage approval are issued for successful applicants.

After Certification

• Certified products will be subject to ongoing surveillance and recertification activities.
• Any significant product, packaging or material changes will require reassessment.
• Certification helps demonstrate that a refillable system has been independently assessed against Circular Living Standards requirements.
