About assessment documentation

Present the assessment evidence with a clear boundary and explanation.

GreenCo is a CII green-company rating system implemented at the unit or facility level. Its focus includes environmental performance and management across areas such as energy, water, materials and greenhouse-gas information. Defining the facility boundary is therefore an essential first step in preparing a meaningful assessment enquiry.

For assessment documentation, agree the product, activity, application or record involved and the working output. Focus the preparation on the information needed at this stage, with clear evidence references and an understandable handover for the person continuing the work.

When this support is useful

Manufacturing and service-sector facilities considering a GreenCo rating can explore this service. The facility’s activities, operating history and current scheme criteria should be reviewed before the preparation scope is fixed.

This subservice can be discussed when the business has reached the relevant stage, received a request for information or identified a gap it cannot resolve from its existing records. Start with the actual request and explain what work has already been completed. That avoids both duplicating earlier preparation and overlooking an unresolved dependency.

GreenCo concerns the rated unit or facility. GreenPro concerns product ecolabelling, while ISO 14001 concerns an environmental management system. Evidence may overlap, but one outcome does not automatically establish another.

The starting information for this work

The task-specific inputs are: Framework checklist, source records and improvement information.

Identify the current version of each input and the person who can confirm it. Keep the original requirement alongside any summary. Where an input has not yet been verified, mark that point clearly so the preparation does not convert an assumption into an application statement.

  • Facility profile and assessment boundary
  • Available energy and water records
  • Material, waste and production information
  • Relevant greenhouse-gas calculation information
  • Environmental management and improvement records
  • Previous rating documents or assessor correspondence

How the work is organised

  1. Index evidence.

    Begin with the relevant source record and the scope agreed with the applicant. Record the fact being checked and identify what would establish it, rather than relying only on a title or a previous file name.

  2. Separate targets from achieved results.

    Compare the related information as a connected set. A change to one attachment can affect a product description, application field or evidence reference elsewhere, so keep those relationships visible.

  3. Link performance claims to their data basis.

    Retain the reviewed result and any question that remains open. Identify the next owner and the evidence needed before the applicant treats the work as ready for the next stage.

The steps should be agreed with the business and adapted to the actual record or product. Where a question requires a technical, regulatory or other professional conclusion, the preparation should identify the appropriate reviewer. Administrative organisation and professional assessment remain different responsibilities.

Evidence and consistency checks

What the topic covers and how to prepare for discussion
AreaWhat to consider
Facility boundaryIdentify the physical unit, activities and reporting period included in the enquiry.
Data reliabilityLink utility, resource and performance figures to accessible source records.
Performance contextExplain production changes or other factors affecting comparisons.
Improvement evidenceConnect objectives and completed actions with a clear method of checking results.

Use this wider service context to check whether the task-specific records remain coherent. For example, names, models, locations and reporting periods should be understandable across related files. If they differ for a valid reason, explain the relationship with the applicant and keep the source evidence accessible.

The working output and its handover

A facility assessment evidence pack.

A useful handover identifies what was reviewed, the version or date, the evidence references and the outstanding questions. It should also identify the next responsible person. That allows another team member or an external reviewer to continue the work without reconstructing the preparation history from scattered messages.

An organised output is not a substitute for the relevant external decision. Where the next step is a submission, test, assessment or professional review, agree who authorises it and which reviewed information will be used. Keep the acknowledgement or response with the same record.

Why careful preparation matters

  • A more transparent view of environmental performance data.
  • Consistent boundaries and periods for review.
  • Clear ownership of evidence across operating teams.
  • Better prioritisation of information gaps and improvement actions.

For this subservice, judge the preparation by how clearly it resolves the task and supports the next decision. An output that still contains unexplained identity or scope differences can create avoidable questions later, even if the folder appears complete. The practical aim is a record that the business can understand and stand behind.

An illustrative working example

A facility reports lower energy use after an equipment change. The preparation team gathers meter records, production information and the implementation date before presenting the claim. It distinguishes the measured result from an estimate and explains any change in output. This helps an assessor understand the evidence without suggesting that a rating has already been earned.

At the assessment documentation stage, the team would focus on this question: Are comparisons adjusted or explained when the operating context changes? The evidence for the answer should be recorded in the working output, with any unresolved point assigned to a person rather than silently treated as settled.

Common issues and the final review

  • Comparing figures from different site boundaries without explaining the change.
  • Treating a projected saving as an achieved operating result.
  • Assuming a facility rating certifies every product made by the company.

The task-specific review question is: Are comparisons adjusted or explained when the operating context changes?

Separate a missing document from an unsupported claim and from a technical question. These need different actions. Obtaining a file may resolve the first; correcting the statement or obtaining competent review may be necessary for the others. Keep those actions visible until the responsible person has reviewed the result.

After this stage is completed

Maintain the data trail and improvement records after assessment. Review boundary changes, new processes and the current rating scheme’s reassessment or reporting conditions.

Retain the task output with the source information, reviewed version and relevant correspondence. If the underlying business facts change before the next submission or assessment, check the effect on the prepared material rather than assuming the earlier result still applies.

Discuss your requirement with TenderCert

Start with the outcome you need and the evidence you already hold. Bring the exact buyer clause, authority request or assessment enquiry where available, together with a short description of the product, activity or site. This makes the conversation more useful than asking for an unspecified certificate.

TenderCert’s consultancy scope can then identify the preparation and coordination tasks to discuss, the person responsible for each input and the questions for the relevant decision-maker. The applicant should review information and declarations before any external submission. Keep the final reviewed version and the acknowledgement together so later follow-up begins from the same record.

Common questions

What is the purpose of assessment documentation?

Present the assessment evidence with a clear boundary and explanation. The preparation scope should be agreed against your actual requirement and the information already available.

What working output should we discuss?

A facility assessment evidence pack. The agreed consultancy scope should identify which parts are included and which decisions belong to an external organisation.

Are comparisons adjusted or explained when the operating context changes?

Use these inputs: Framework checklist, source records and improvement information. Index evidence. Separate targets from achieved results. Link performance claims to their data basis. Retain the supporting references with the reviewed output.

Can we submit estimates?

Identify estimates clearly and explain their basis. The assessor determines the evidence it will accept under the relevant requirements.

Does our ISO 14001 certificate establish a GreenCo rating?

No. They are distinct assessment arrangements with different scopes.

Are all the documents listed here compulsory?

The checklist is a preparation aid, not a universal statutory list. Confirm the current route and the facts of the application before treating any particular attachment as mandatory.

What should we send for the first conversation?

Begin with a short business description, the original requirement and the stage already reached. The team can then identify the relevant preparation scope and any specialist review needed.
