12 Common Mistakes on Waste Transfer Notes (and How to Avoid Them)

Waste transfer notes (WTNs) are a cornerstone of the UK's duty of care framework under Section 34 of the Environmental Protection Act 1990. Yet even experienced businesses make the same avoidable mistakes, leaving them exposed to fixed penalty notices, criminal prosecution, and in the most serious cases, liability for the costs of cleaning up illegally dumped waste. This article catalogues the 12 most common errors, grouped by category, so you can identify and correct them before an Environment Agency officer does.

Mistakes 1–4: Waste Description Errors

Mistake 1: Vague Waste Descriptions

Writing "general waste" or "mixed waste" in the waste description field of a WTN is one of the most widespread failures in duty of care compliance. It is also one of the most easily avoided.

The Duty of Care Code of Practice (2016), issued under s.34(7) of the Environmental Protection Act 1990, sets out that a waste description must be sufficient to enable the waste to be handled safely and legally at every subsequent stage of its journey. "General waste" tells a receiving operator nothing about what they are handling. It provides no information about whether the waste might be hazardous, what treatment it requires, or how it should be stored.

A compliant description identifies the physical form of the waste, the main constituents, and where relevant, the source. For example: "Mixed commercial waste comprising cardboard packaging, plastic shrink-wrap, polystyrene, and food waste from a supermarket distribution centre" is adequate. The description must also be consistent with the European Waste Catalogue (EWC) code selected, if you describe "office waste" but assign a construction waste EWC code, that inconsistency will be a red flag under inspection.

Mistake 2: Wrong EWC Code

The European Waste Catalogue, retained in UK law post-Brexit under the Waste (England and Wales) Regulations 2011 (SI 2011/988) and associated retained EU law, assigns a 6-digit code to every type of controlled waste. Using the wrong code is a common and consequential error.

A particularly frequent mistake is using 20 03 01 (mixed municipal waste) for what is actually 17 09 04 (mixed construction and demolition waste not containing dangerous substances). These are entirely different waste streams requiring different handling, different permits at receiving sites, and different disposal routes. Using the wrong code can mean waste is taken to a site not authorised to accept it, a serious offence for both carrier and producer.

Mirror entries add further complexity. Some EWC codes exist in both hazardous and non-hazardous versions — for example, 17 09 03* (construction and demolition waste containing dangerous substances, hazardous) and 17 09 04 (mixed construction and demolition waste, non-hazardous). When a mirror entry applies, you must assess which version applies to your specific waste. If you select the non-hazardous code for waste that is actually hazardous, you have committed a serious breach, hazardous waste requires a consignment note, not a WTN. See our guide on EWC codes explained for a full breakdown of how to select the correct code.

Mistake 3: Inconsistent Waste Description

The waste description on the WTN must accurately reflect what is actually in the vehicle or container at the time of transfer. It is not sufficient to prepare a WTN describing "office paper and cardboard" when the skip being collected actually contains a mixture of construction rubble, broken furniture, and general office waste.

Environment Agency officers carry out roadside checks and site inspections. They are entitled to inspect waste in transit and compare it against the WTN description. A material discrepancy between the description and the actual waste is treated as evidence of a fraudulent WTN, a criminal matter, not an administrative oversight. In serious cases, it may also indicate that the waste was misclassified to avoid proper disposal costs, which constitutes waste crime.

If the composition of a mixed load changes between when the WTN was prepared and when the waste is actually collected, the WTN must be updated before transfer takes place. The simplest way to avoid this is to complete the WTN at the point of collection, not in advance.

Mistake 4: Missing or Inadequate Quantity Information

Stating "1 skip" or "3 bags" as the quantity on a WTN is not sufficient. The Environmental Protection (Duty of Care) Regulations 1991 (SI 1991/2839), Regulation 2, require the quantity of waste to be stated. Best practice, and increasingly the standard expected under inspection, is to state an approximate weight in tonnes or volume in cubic metres.

"Approximately 3 tonnes of mixed commercial waste" is acceptable. "One 8-yard skip" is not, because it provides no information about the actual quantity of waste. The reason quantity matters is downstream: receiving sites use WTN quantities to compile their waste acceptance records; discrepancies between stated and actual quantities are a known indicator of illegal waste activity.

Where weighbridge tickets are available (as they often are at licensed treatment and disposal sites), the actual weight should be used. For collections from sites without weighbridges, a reasonable estimate is acceptable provided it is clearly labelled as an estimate.

Mistakes 5–8: Party and Registration Errors

Mistake 5: Not Checking Carrier Registration

One of the most common, and legally most dangerous, mistakes is taking a carrier's word that they are registered. A carrier who tells you they hold an upper tier registration, or hands you a business card claiming they are "fully licensed", is not sufficient evidence of registration. You must independently verify their registration on the Environment Agency's public register.

The public register is freely searchable at environment.data.gov.uk/public-register. You can search by company name or registration number. If the carrier is not found on the register, they are not registered , it is that simple. You cannot rely on assurances, outdated paperwork, or a registration number that turns out to be incorrect or expired.

The reason this matters so much legally is that the duty of care under s.34 EPA 1990 falls on the waste producer regardless of what the carrier told them. If you hand waste to an unregistered carrier and they fly-tip it, you are in breach of duty of care. The carrier's misrepresentation may be a relevant factor in enforcement discretion, but it is not a legal defence. See our guide to theEA waste carrier register search for step-by-step verification instructions.

Mistake 6: Wrong Registration Number on the WTN

The WTN must include the carrier's registration number. This is the unique identifier on the EA public register, prefixed CBDU (upper tier) or CBDL (lower tier). Errors here include: transcribing the number incorrectly from the carrier's documentation; using an old number from a previous registration period; or, in the rare case where a business holds both types of registration, using the wrong tier's number.

The registration number is the primary verification mechanism. If an EA officer checks a WTN and the registration number does not exist or does not match the carrier's details, the WTN is effectively unverifiable, and the waste producer cannot prove they used an authorised carrier. Always copy the registration number directly from the EA register rather than from the carrier's own documentation.

Mistake 7: Missing Transferee Permit or Exemption Details

The transferee, the party receiving the waste, must hold legal authority to receive it. For a waste carrier, this is their carrier registration. But for a receiving site (a treatment, storage, or disposal facility), the relevant authority is an environmental permit or registered exemption, not a carrier registration number.

The WTN must include the permit number or exemption reference of the receiving site. A surprisingly common error is recording the carrier's registration number in the transferee section and nothing further, which only evidences that the carrier is authorised to transport, it says nothing about whether the destination site is authorised to receive that particular waste type.

Environmental permits are issued by the Environment Agency and are searchable on the EA's public register. Before using a new receiving facility, check their permit online and confirm it covers the EWC codes you are transferring. Record the permit number on the WTN.

Mistake 8: Wrong Transferor Details

On shared or multi-tenanted sites, multiple businesses may operate under one roof, each producing their own waste. A frequent mistake is for one entity to complete WTNs using another entity's name, particularly where a parent company, subsidiary, or associated business operates nearby.

The legal entity named as transferor must be the entity that produced or holds the waste at the point of transfer. Using a trading name rather than the registered company name also causes problems: EA records and enforcement action are indexed to registered company names and numbers. "Smith's Builders" tells an enforcement officer far less than "Smith Building Services Limited (Company No. 12345678)". The correct registered company name, not a trading name, should appear on every WTN.

Mistakes 9–12: Administrative Failures

Mistake 9: Missing Signatures

Both the transferor and the transferee must sign the WTN. An unsigned WTN, or one signed by only one party, is invalid. This is not a technical requirement that can be overlooked: the signature is what creates the legal record that the transfer took place between those specific parties at that specific time.

For digital WTNs, an electronic signature from both parties is required. Electronic signatures are valid under the Electronic Communications Act 2000, provided both parties have consented to transact digitally. The signature date must match the date of transfer, a signature dated the day after the transfer is technically invalid, though likely to be treated as an administrative error rather than evidence of fraud, provided everything else is in order.

Practical tip: do not allow the carrier to leave your site without completing their signature on the WTN. Once the waste has gone, obtaining a retrospective signature is much harder and creates its own compliance risk.

Mistake 10: Not Keeping Your Own Copy

Both parties to a waste transfer must retain their own copy of the WTN for a minimum of two years from the date of transfer, under Regulation 4 of the Environmental Protection (Duty of Care) Regulations 1991 (as amended). "The carrier has a copy" is not a defence.

This distinction matters in practice. If the EA request to inspect your waste records, they will expect to see YOUR retained copies, not be directed to your carrier. Each party independently holds the obligation to retain records, and each party can be separately prosecuted for a failure to do so.

Paper copies should be stored in a dedicated folder, filed by date or carrier. Digital systems that automatically retain your copy on secure cloud storage are far more reliable, you cannot lose them, they cannot be damaged, and they can be produced instantly on request.

Mistake 11: Using Season Tickets Incorrectly

Season tickets allow a single WTN to cover multiple transfers of the same waste between the same parties without a new note being issued for each individual transfer. They are a legitimate administrative simplification under the Duty of Care Code of Practice (2016), Section 3.

However, season tickets are strictly limited. A season ticket can only be used where: the waste type is the same for every transfer covered by the ticket; the transferor and transferee are the same for every transfer; the site of transfer is the same for every transfer; and the period does not exceed 12 months.

If any of these elements change, a different carrier collects, a new waste type is included, a different site is used, a fresh individual WTN is required for that transfer. Using a season ticket to cover a transfer that does not match the ticket's parameters means that transfer has no valid WTN. The mistake usually occurs when businesses set up season tickets and then fail to review them when their circumstances change.

Mistake 12: Backdating or Pre-dating WTNs

The date on a WTN must be the actual date of transfer. Backdating a WTN, recording an earlier date to cover a collection for which no WTN was completed at the time, is a falsification of a legal record. Under the Fraud Act 2006, creating a false record with intent to make a gain (avoiding a penalty, for example) is a criminal offence.

Pre-dating, completing a WTN before the transfer has actually taken place, is also invalid. If the transfer does not happen on the date recorded, or happens differently from how it was anticipated, the pre-dated WTN is inaccurate and potentially misleading.

The solution is always to complete the WTN at the point of transfer. Digital tools that timestamp entries at the point of data entry provide an automatic audit trail that makes backdating impossible to conceal.

How to Avoid All 12 Mistakes

The common thread running through all 12 mistakes is either incomplete information, inadequate verification, or inadequate record-keeping. All three can be significantly reduced by moving from paper to a purpose-built digital waste transfer note system.

A good digital WTN platform will:

• Require all mandatory fields to be completed before the note can be submitted, eliminating incomplete WTNs
• Provide an EWC code lookup tool so users can find and confirm the correct 6-digit code
• Prompt users to check and enter carrier registration numbers, with a direct link to the EA register
• Require electronic signatures from both parties before the note is finalised
• Automatically retain records for both parties in cloud storage for the required 2-year period
• Timestamp all entries, making backdating impossible
• Validate season ticket parameters and alert users when a new individual WTN is required

Beyond technology, robust internal processes make a significant difference. Designate a specific person responsible for waste compliance. Create a standard operating procedure for waste collections that includes carrier verification, WTN completion, and record filing as mandatory steps. Train all staff who handle waste or deal with carriers on the basics of the duty of care. Conduct an annual review of all carriers, permits, and season tickets.

The consequences of getting this wrong are not abstract. Fixed penalty notices for record-keeping failures start at £300. For more serious breaches, handing waste to unregistered carriers, missing WTNs across multiple transfers, unlimited fines on criminal prosecution are possible. Where waste is fly-tipped by an unregistered carrier you negligently used, cleanup costs can be recovered from you by the landowner or local authority.
