Facilities and building managers in London may need to explain a supplier choice to an occupier, asset manager or procurement team. A proposal can sound persuasive while leaving important questions unanswered. Does a claim describe one cleaning product, the equipment, transport or the entire service? Is a comparison based on the same task? Can the information be retained with the agreed scope so the next manager understands what was actually offered?
This article provides a question sheet for assessing the evidence. It does not certify Pristine or another supplier, calculate a carbon footprint or determine compliance with environmental law. It is a practical way to separate a supported statement from information that still needs clarification.
Write down the exact claim first
Start with the wording in the proposal, website or product document. Preserve the date and source. Avoid changing “a product has a particular credential” into “the whole cleaning service is certified” when you summarise it internally.
Ask which part of the proposed work the statement describes. A product used for a specific treatment may be one part of a visit. A method comparison may apply only to certain carpeted zones. An equipment feature does not automatically describe transport, other products or every task in a larger contract.
Be cautious about supplying missing meaning yourself. If a statement says “less water”, ask for the comparison and intended scope. If it says “sustainable”, ask which aspect is being described and what the supplier can substantiate. The next useful step is a precise question, not an unsupported assumption that the claim must cover everything.
The Competition and Markets Authority’s Green Claims Code is a useful reference for understanding environmental marketing claims. Its guidance concerns consumer-facing claims; this article uses it as context for clearer purchasing questions, not as a conclusion about the legal position of a particular commercial contract.
Separate product evidence from service evidence
If a proposal refers to a product credential, request the exact product name and relevant supporting information. Check that the information relates to the product proposed for the assessed work. A brochure covering several products may not establish which one is intended for your carpet.
Ask what the credential actually covers and whether it remains current where that matters. Do not assume that a symbol has the same scope as another scheme with a similar appearance. If you need a formal procurement determination, use the appropriate competent review rather than treating a logo in a quotation as the whole answer.
Keep carpet suitability separate. A product with environmental information still needs to be appropriate for the actual material, condition and manufacturer’s instructions. A product attribute does not establish that an unidentified carpet can receive a particular treatment.
Likewise, product information alone does not measure the full visit. If the supplier makes a wider claim about a service, ask for the supporting basis at that level. The point is not to demand an invented report from every small enquiry; it is to avoid describing a narrow piece of evidence as proof of a much broader statement.
Ask for a meaningful comparison
A percentage or reduction claim needs a defined basis before it can be compared with another proposal. Ask what is measured, the reference method or period and the conditions assumed. Record whether the figure is measured, modelled or an indicative estimate supplied by someone else.
The tasks being compared also matter. A proposal for maintaining a lightly soiled zone and a proposal for an assessed restorative clean may have different objectives. A resource comparison that ignores those differences can be unhelpful even if each supplier’s description is otherwise accurate.
Avoid converting a general product or equipment figure into a forecast for your building. The actual areas, condition, method and working arrangement need to be understood. If the proposal does not contain a site-specific measurement, label it accordingly in the procurement record.
Ask the supplier to explain the uncertainty in plain language. “Not measured for this visit” can be an honest and useful answer. It should not be replaced by a number added to make an internal comparison table look complete. A transparent gap is preferable to a false impression of precision.
Keep material suitability ahead of a marketing label
The proposed method must remain appropriate for the carpet. Request available product and care information and identify the limits of the survey. Where a material or treatment is uncertain, keep that decision open until the relevant assessment is made.
Pristine does not hot-water-extract viscose, rayon or art-silk materials. An environmental claim, a procurement target or an approaching deadline does not change that boundary. The existing carpet specification article explains what information a manager can request before wet cleaning is considered.
Do not assume that one method is the right answer for every carpet because a proposal presents it as environmentally preferable in general terms. Ask why it is proposed for the assessed zones and what outcome it is intended to achieve. Suitability and any environmental comparison should both be explained without turning either into a universal claim.
If a representative test is proposed, agree its purpose and limits. A visual result in one area does not measure a whole-service environmental impact. Keep the technical assessment and any resource evidence distinct in the written record.
Use a claim-evidence question sheet
The following is an original working template for a procurement discussion. It is not a certification form or a legal compliance assessment. Leave a field marked unknown if the evidence has not been provided.
Swipe across the table to see all columns →
| Question | Information to request | What the manager should record |
|---|---|---|
| What is the exact claim? | Original wording and dated source | Preserve the wording without expanding it |
| What does it cover? | Product, method, equipment or stated service scope | Note areas and exclusions |
| What is the comparison? | Reference task, method or period | Whether tasks are genuinely comparable |
| What supports it? | Relevant document or explanation | Evidence received and unresolved questions |
| Is it specific to this building? | Measured, modelled or general basis | Keep estimates separate from visit measurements |
| Who will clarify the gap? | Named supplier or procurement contact | Next action and decision owner |
Use the same questions for comparable claims from different suppliers. Do not add a numerical sustainability score unless your organisation has an appropriate method and the evidence required to apply it. This table is deliberately a set of questions rather than a ranking system.
Retain the answers with the actual quotation version. A later change to the product, method or scope may require the evidence to be revisited. A claim attached to an earlier proposal should not automatically be carried over to a different instruction.
Discuss site arrangements without inventing disposal instructions
Ask the contractor what site information it needs for the proposed work, including any relevant arrangements for water, equipment and waste arising from its task. The responsible people should establish suitable arrangements for the actual visit.
Do not use a generic blog paragraph to authorise a particular disposal route or assume that every water point or drain is suitable. Site restrictions, the nature of the work and the relevant requirements need to be assessed by the people responsible. This article does not provide discharge, chemical handling or waste-classification instructions.
Keep the approval route clear if a proposed arrangement is unavailable. The contractor and authorised site contact need to agree the next step rather than improvise beyond the assessed scope. Any effect on method, access or price belongs in the written discussion.
For the wider building brief, use the commercial carpet survey checklist. The environmental question sheet supplements that brief by recording what has actually been claimed and evidenced. It does not replace the survey or the building’s procedures.
Avoid unsupported claims about replacement and lifespan
Carpet care and replacement decisions can be discussed together, but a cleaning quotation does not automatically quantify years of additional life, avoided replacement or carbon savings. Those claims need their own supporting basis and appropriate boundaries.
Ask what condition the contractor has actually assessed and what cleaning can reasonably address. Soil, wear, damage, fading and installation issues are different considerations. A supported cleaning scope should explain its limitations without promising that every carpet will return to a new appearance.
Where your organisation is considering repair or replacement, keep the relevant specialist information with that decision. Do not convert a successful cleaning photograph into proof of a measured environmental saving. The photograph may illustrate the result of that particular task; the environmental calculation would need separate evidence.
The existing commercial maintenance page covers ongoing care and the building-level programme discussion. This article adds a purchasing question: what evidence supports a specific environmental statement made about that proposed programme?
Record what was agreed and what remains unmeasured
At approval, summarise the agreed scope and the precise claims supported by the information received. Record any estimates as estimates and identify material gaps. If the organisation chooses a supplier for operational reasons as well as environmental considerations, describe those reasons accurately rather than retrofitting an environmental justification.
After the visit, retain the agreed completion record and any measurements that were actually collected. Do not create retrospective figures for water, energy or emissions simply because the original procurement question sheet had a field for them.
Where a supplier statement changes, preserve the relevant business evidence and update the current decision record appropriately. The next facilities manager should be able to distinguish what was said at quotation, what was approved and what was observed at completion.
For a comparison of the commercial cleaning scope itself, use the quotation comparison article. The purpose here is different: to ensure that environmental language is no broader or more certain than the evidence available for it.
Questions London facilities managers ask
Does a product credential certify the whole carpet-cleaning visit?
Do not assume so. Check what the credential covers and what the supplier is claiming. Product information and whole-service evidence answer different questions and should be recorded separately.
Can a supplier quote a saving without measuring our building?
Ask for the basis and limitations. A general or modelled comparison should be labelled as such. It should not be presented internally as a measured result for your particular visit unless that is supported.
Is low-moisture cleaning always the most suitable choice?
Suitability needs assessment against the actual carpet and task. A broad environmental description does not establish that a method will meet every building’s cleaning requirements or material restrictions.
Does Pristine claim a particular environmental certification or carbon saving here?
No. This article supplies questions for a supplier discussion. It does not claim a certification, percentage reduction, carbon-neutral service or independently measured environmental result for Pristine.
