When you check waste suppliers for several clients, the same carrier or receiving site may appear repeatedly. Sharing source research can save time, but each client still needs a decision about its own arrangement. Different waste streams, destinations and responsibilities can lead to different conclusions about the same supplier.

Start by recording who your client is, what you have agreed to do and who can act on your findings. That gives you somewhere to send an urgent question before the next collection, as well as a clear basis for routine reporting.

The procedures suggested here suit consultants and other advisers working across separate client organisations in England, Scotland and Wales. Use the monitoring and supplier management guide for the wider review process. Your actual activities determine any legal duties you hold, including whether you are acting as a waste broker.

What should you agree with each client before starting?

Write a short scope covering the client’s legal entity, producing premises, waste streams and suppliers. Specify whether you will research public records, obtain supplier answers, assess collection evidence or recommend a decision. Identify the information the client will supply and any access you need.

Agree who approves the arrangement and who can pause an affected collection. Those responsibilities may sit with different people. A procurement contact might approve the contract while a site manager controls tomorrow’s handover. Give your team both contacts and an alternative for absence.

Explain the limits of the work in ordinary language. For example, a review of a proposed receiving site’s authorisation does not establish what happened to every previous load. The client should understand which questions remain outside the assignment and where specialist advice may be needed.

Keep a dated version of this agreement with the client’s file. If the client later asks you to arrange collections or manage destinations, review the scope and your role before taking on the additional activity.

When might an adviser also be acting as a waste broker?

Researching records and arranging waste management are different activities. Your job title does not settle the regulatory position. In England, GOV.UK registration guidance includes businesses that arrange for someone else to buy, sell or dispose of waste.

Check what you do in practice, including instructions given to carriers, decisions about destinations and contractual arrangements made for clients. If those activities amount to brokering, assess the relevant registration and duty of care obligations. Physical possession of the waste is not a prerequisite for every broker duty.

Scotland’s broker and dealer chapter explains the Scottish responsibilities. Wales uses NRW as its regulator. Ask the appropriate regulator or a competent adviser if the boundary is unclear for your service.

Keep that assessment current when the service changes. A consultancy initially engaged only to supply research may later begin booking collections. Updating the engagement letter helps clarify responsibilities, but the regulatory position follows the actual activity rather than the label chosen for the agreement.

How should you separate shared research from client decisions?

Maintain a source record for the particular business or site you researched. Give it its official identifiers, source URL, access date and relevant document dates. Record what you found and any limits on the information available.

Then create a separate client review showing why that evidence matters to the client’s arrangement. Identify the relevant waste, activity and service period. The source record can be reused where appropriate; the client’s conclusion needs its own reasoning and date.

For example, two clients might use one carrier but send waste to different facilities. Sharing the carrier registration check can be sensible. A permission check for the first facility cannot support the second facility merely because the carrier is common to both arrangements.

Our guide to recording supplier review evidence explains the source record. Use waste supplier monitoring reports to turn that research into a client-specific account of findings and required decisions.

Which identifiers help prevent records crossing between clients?

Give every client and assignment a stable internal reference. Store the client’s legal identity separately from its trading name. Add the originating premises and the supplier’s actual role so a shared account label cannot obscure whose waste is involved.

For suppliers, keep company numbers where relevant, carrier references and site authorisation references in their own fields. Each identifies something different. A registration belonging to one group company should not become evidence for another through an automatic name match.

Use descriptive file references that survive staff changes. A folder named current customer is difficult to interpret a year later. A client reference, review date and assignment name make the same record easier to recognise without relying on a particular colleague’s memory.

When importing data from a client’s spreadsheet, check a sample against the originals. Similar names, shared billing addresses and abbreviated site names deserve attention. Keep uncertain matches unresolved until you have an explanation supported by the available evidence.

Can one current check be used for several clients?

Reuse a check only after considering its scope and age. Ask whether it concerns the same legal person, the same permission question and the period relevant to the new client. A recent access date does not make every underlying document a complete current position.

The Environment Agency’s public-register guidance describes how environmental information is available in England. Sources can vary in coverage and document access. Retain those limitations where they affect a conclusion.

Record when each client’s reviewer relied on shared evidence. If a later source changes, you can identify which reviews used the earlier version and assess the affected arrangements. Preserve that earlier evidence so the client’s original decision remains understandable.

Avoid a shared approved-supplier flag that automatically approves every client service. A carrier can be relevant to several arrangements while a particular waste stream, destination or subcontractor still needs separate checking. Approval belongs to the defined arrangement.

How do you prioritise work when several clients need attention?

Begin with questions that could affect an imminent transfer or safe waste management. Identify the next collection, the uncertainty and the person who can take action. A routine missing company detail and a concern about destination permission need different responses.

Agree service expectations with each client, including how urgent findings are communicated. Your consultancy’s reporting timetable should not leave a client unaware of a concern until a monthly report arrives. Keep a method for confirming that the responsible person received the message.

The England and Wales duty of care code, section 3.2 says waste must not be given to or taken from someone suspected of lacking an appropriate permit or registered exemption, or breaching its conditions. Report suspected illegal activity or breaches to the relevant regulator.

A failed search alone does not establish those facts. Investigate the actual evidence and affected activity, while making sure the client receives enough information to address any suspicion before a transfer. See investigating supplier alerts for that assessment.

What if a shared supplier changes its destination?

First establish which service changed. A new destination for one waste stream or collection area may affect only part of your client list. Ask the supplier for the effective date, receiving operator and proposed activity, then compare them with each client’s arrangement.

Identify the clients whose reviews relied on the previous destination. Give each an assessment of its own affected transfers and any action needed. Preserve the original route information and the explanation of the change instead of replacing the address everywhere without a history.

Keep client instructions separate. One client might have an authorised alternative ready while another needs further work to arrange a suitable route. A common supplier notification does not determine an identical operational response.

Use waste supplier review triggers to decide what needs rechecking. If a central answer resolves several client enquiries, reference it in each file and explain how it applies, including any unanswered client-specific question.

How should confidential client information be handled?

Keep public-source research distinguishable from client records and supplier communications obtained for an assignment. A public permit document and a client’s pricing, production details or internal investigation do not have the same sharing context.

Limit access according to the assignment and your organisation’s applicable information-handling requirements. Before sharing a cross-client summary, establish what can be disclosed and whether the information could identify another client’s operations. Obtain appropriate advice where personal data or contractual confidentiality requires it.

Use neutral references when discussing a common source issue with a supplier. You can ask whether a registration reference is correct without disclosing another client’s waste volumes or commercial terms. Keep unnecessary client detail out of the shared supplier research file.

If an information request needs client authorisation, obtain it before sending the material. Record the purpose and permitted scope. A client approving research into its supplier does not automatically authorise circulation of its internal documents to everyone who uses the same supplier.

How should different national rules appear in the workflow?

Record where the waste arises and where the relevant activities occur. The location of your consultancy’s office does not determine the regulatory framework for each client. A client with Scottish and Welsh operations may need different instructions within one assignment.

The Scottish producer code and NRW’s duty of care guidance provide national starting points. Use the relevant regulator’s register and guidance for the question being checked.

Keep specialist document processes clear. Hazardous waste and Scottish special waste require their applicable procedures. An adviser can coordinate record enquiries, but should not imply that one ordinary transfer-note template covers every client’s material and movement.

Ask for specialist input when a cross-border route or unusual activity exceeds your competence. Record the question asked and the advice received. A national label in a spreadsheet is useful only if the actual assessment follows the right framework.

What should you do when a client disagrees with your finding?

Discuss the evidence and the proposed activity. A client may hold information that you have not yet seen, such as an operator clarification or a corrected collection record. Add it to the review and explain whether it changes your assessment.

Keep a disputed interpretation distinct from an unresolved factual question. If the disagreement concerns the effect of a permit condition or another legal issue, seek competent advice. Avoid resolving it by selecting whichever source makes the preferred commercial decision easier.

Record the client’s decision, the advice supplied and any remaining concern. That record supports accountability but does not remove duties held by you or other waste holders. Where your own activities create regulatory obligations, follow those obligations independently of the client’s approval process.

Agree the next step explicitly. It might be a regulator enquiry, further supplier evidence or an alternative arrangement. A note saying discussed with client leaves the next reviewer unable to tell whether the problem was resolved or merely acknowledged.

What might a practical two-client review look like?

Consider a fictional adviser working for a bakery and an engineering firm. Both use the same collecting business. The bakery has a routine food waste arrangement; the engineering firm has a separately assessed hazardous stream. Their destinations and documents differ.

The adviser checks the collecting business’s identity and retains dated registration evidence in a shared research record. Each client file references that check. The adviser separately reviews the appropriate receiving arrangements and requests the relevant movement evidence for each waste stream.

A supplier message then announces a change affecting only the bakery’s route. The adviser identifies the bakery’s forthcoming collection, checks the replacement destination and tells its responsible contact what remains unresolved. The engineering firm’s decision remains based on its own unchanged route, with the shared message assessed for relevance.

The resulting records show why one client needed immediate follow-up while the other did not. Neither file implies that the shared carrier check assessed every waste activity performed by that business or guaranteed all future collections.

What should you establish when a new client joins?

Before an assignment starts, request one recent completed collection record and the latest supplier review. Compare them with the client’s description of the service. This can reveal an unmentioned subcontractor or destination before you build a monitoring list around the wrong arrangement.

Ask the client to confirm any discrepancy with the people operating the premises. An accounts contact may know the contracting supplier but have no knowledge of the collecting vehicle or material presented. Record which colleague supplied each operational fact and when it was confirmed.

Where the client has no existing review, identify the initial questions needed to establish the arrangement. Agree whether that baseline work falls within your assignment. A promise to monitor changes is difficult to fulfil responsibly when neither party has established what the current service involves.

How should you hand over work when an assignment ends?

Give the client its agreed final record, with evidence references, unresolved questions and the current responsible contacts. Explain where original movement documents remain and what access the client needs after your service ends.

Keep retention decisions appropriate to the material and applicable obligations. Client review evidence, transfer notes and specialist registers can have different bases. Read waste record retention periods before promising one deletion period for the entire assignment.

Agree what happens to shared research and confidential client information. Your firm’s ability to retain a public-source observation does not determine its right to retain or reuse every document supplied by a former client. Follow the engagement terms and applicable requirements.

Test the handover with one open question and one completed review. The receiving person should be able to identify the supplier, scope and next action without contacting the departing adviser for an explanation. Keep the date on the final report so later readers can see the period it covers.
