How to Check a Waste Carrier Licence in the UK (2026)
Step-by-step guide to checking any waste carrier's licence against the EA, NRW, SEPA & DAERA registers. Stay compliant and avoid unlimited fines.
Why This Check Could Save Your Business
If you hand waste to an unlicensed contractor and they fly-tip it, the law can hold you responsible, even if you had no idea what they planned to do with it. That is not a technicality buried in the small print. It is a core principle of duty of care law under the Environmental Protection Act 1990, and regulators actively enforce it.
The good news: protecting yourself takes about five minutes. Checking a waste carrier licence before you engage any contractor, and keeping a record of that check, is the single most effective compliance action a UK business can take when it comes to waste.
This guide explains exactly how to do it, which registers to check, what the results mean, and how to build a repeatable process that protects your organisation every time.
The Legal Duty Every UK Business Carries
Under the Duty of Care Regulations 1991 (as amended), any business that produces, imports, stores, treats, or disposes of controlled waste must ensure that waste is only transferred to an authorised person. Authorised persons include:
- A registered waste carrier (Upper or Lower Tier)
- A holder of an environmental permit for waste operations
- A waste exemption holder (for qualifying activities)
- A local authority
Passing waste to anyone outside this list, including a carrier whose registration has simply lapsed, is a breach of duty of care. Penalties include unlimited fines, prosecution, and a requirement to fund remediation of any illegally deposited waste.
The Environment Agency stepped up enforcement activity through 2024 and 2025, and 2026 continues that trajectory. Fly-tipping prosecutions increasingly target waste producers as well as carriers, particularly in cases where due diligence checks were absent or poorly documented.
The Four UK Waste Carrier Registers
Waste carrier registration in the UK is devolved. Your contractor's licence will be held on one of four national registers depending on where they operate:
| Register | Authority | Covers |
|---|---|---|
| Environment Agency (EA) | EA | England |
| Natural Resources Wales (NRW) | NRW | Wales |
| Scottish Environment Protection Agency (SEPA) | SEPA | Scotland |
| DAERA | Dept of Agriculture, Environment and Rural Affairs | Northern Ireland |
A waste carrier working across England and Wales needs registrations on both the EA and NRW registers. A carrier based in Scotland but collecting in England needs both SEPA and EA registrations. Checking only the EA register is one of the most common mistakes businesses make, and it leaves real gaps in your compliance coverage.
Use CarrierCheck to search all four registers simultaneously
Step-by-Step: How to Check a Waste Carrier Licence
Step 1 - Request the Registration Number
Before any waste is collected, ask your contractor for their waste carrier registration number. A legitimate Upper Tier carrier will provide this without hesitation. In England, EA Upper Tier numbers typically follow the format CBDU000000. Some older registrations use prefixes such as EAWML.
If a contractor hesitates or claims they do not have one, that is a serious warning sign. Do not proceed.
Step 2 - Search the Relevant Register
You have two approaches available.
Manual searches (free, but slow):
- England (EA): Search via the Environment Agency's public register on GOV.UK
- Wales (NRW): Use the NRW public waste carrier register
- Scotland (SEPA): Search SEPA's waste carrier register page
- Northern Ireland (DAERA): Use DAERA's carrier and broker register
Each register is a separate visit, a separate interface, and gives you no unified audit trail.
Single search via CarrierCheck:
CarrierCheck queries all four UK registers in one lookup. Enter a company name or registration number and get an instant result showing registration status, tier, and expiry date across every devolved register, simultaneously.
Step 3 - Interpret the Result
When you run your check, confirm all of the following:
- Status is Active - not expired, revoked, or surrendered
- Tier is Upper - if the contractor is collecting your waste (see section below)
- Registered entity matches - the legal name on the register should match the company on your contract or invoice
- Registration covers the waste type - some carriers have scope restrictions
Step 4 - Record Your Check
This is the step most businesses skip, and it is the one that matters most when an inspector arrives.
Your record should capture:
- The date of the check
- Which register was searched
- The result, including registration number, status, and expiry date
- The name of the person who performed the check
A timestamped screenshot is the minimum acceptable standard. A system that logs checks automatically is far better for organisations managing multiple carriers or multiple sites. CarrierCheck maintains a searchable log of every check your team performs, so your audit trail builds itself in the background.
Step 5 - Re-Check Regularly
A carrier registered today may not be registered next year. Upper Tier registrations last three years and must be renewed. They can also be revoked at any time. Best practice is to re-verify:
- Before every new contract or significant new engagement
- Every six months for ongoing supplier relationships
- Immediately if you have any reason to question a carrier's circumstances
Upper Tier vs Lower Tier: What the Difference Means for You
Every carrier check returns one of two registration tiers, and they are not interchangeable.
| Lower Tier | Upper Tier | |
|---|---|---|
| Who it covers | Businesses carrying their own waste incidentally | Professional waste carriers collecting third-party waste |
| Typical example | Plumber removing old pipes from a job | Skip hire company, waste management firm |
| Can they collect your waste? | No | Yes |
| Registration expires? | No (but can be revoked) | Yes, every 3 years |
| EA fee required? | No | Yes |
If the check returns a Lower Tier registration for a contractor you are paying to remove your waste, they are not authorised for that activity. Using them puts you in breach of duty of care regardless of how long you have worked with them.
Common Mistakes That Leave Businesses Exposed
Checking once at onboarding and never again
Registrations expire. A carrier verified in 2024 may have lapsed by 2026. One-off checks give a false sense of security for long-term supplier relationships and will not hold up under regulatory scrutiny.
Only checking the EA register
If your contractor operates across borders, collecting in England but based in Scotland for example, the EA register alone will not give you the full picture. Always check all registers relevant to where the carrier operates.
Accepting a certificate photocopy as proof
Waste carrier certificates can be forged. A photocopy proves nothing. The only reliable confirmation of active registration is a live search of the public register itself.
Conflating carrier registration with an environmental permit
A waste carrier licence covers transport only. If your contractor also operates a waste transfer station, treatment facility, or recycling site, they need a separate environmental permit for those activities. These are checked on a different register entirely and require separate verification.
No documented audit trail
Even diligent checkers can fail a regulatory audit if they have no records to show for it. Enforcement officers will ask to see evidence of checks, and "we always check, we just did not write it down" is not a defence that holds up.
What Happens When a Carrier's Licence Has Lapsed
If you transfer waste to a carrier whose registration has expired or been revoked, a range of consequences can follow:
- Duty of care liability - you are legally responsible for passing waste to an unauthorised person
- Fly-tipping liability - if the carrier abandons the waste, you may be required to fund the remediation
- Regulatory investigation - the EA and devolved authorities investigate producers as well as carriers in serious cases
- Insurance gaps - many commercial liability policies exclude incidents arising from non-compliant waste handling
- Reputational damage - ESG reporting and procurement frameworks increasingly require demonstrable waste compliance
The direct cost of a single fly-tipping incident, including legal fees, clean-up costs, and potential fines, routinely runs to tens of thousands of pounds. Carrier monitoring costs a fraction of that.
Building a Waste Carrier Compliance Process
For organisations managing multiple sites, contractors, or regulated supply chains, ad-hoc checks are not enough. A structured process is essential.
The five components of a robust process:
- Supplier onboarding checklist - carrier registration verification is a mandatory gate, not an optional step
- Approved carrier register - a centralised record of all verified carriers, their registration details, and last-checked date
- Renewal tracking - diary entries or automated alerts tied to each carrier's expiry date
- Clear escalation policy - defined steps for when a carrier cannot demonstrate active registration
- Regular audits - an annual minimum review of your full carrier list against live register data
CarrierCheck was built to support exactly this kind of process. You can monitor an entire portfolio of carriers from a single dashboard and receive automatic alerts the moment any registration status changes, so lapses are caught before they become liabilities.

2026 Updates: What Has Changed
Several developments from 2025 into 2026 are directly relevant to UK businesses managing waste compliance.
Increased EA enforcement focus. The Environment Agency published updated enforcement priorities in late 2025, with waste crime and producer due diligence named explicitly as areas of increased scrutiny. Businesses that cannot demonstrate documented verification are being treated as higher-risk targets.
ESG and procurement pressure. More large contractors and public sector bodies now require suppliers to evidence documented carrier verification as part of pre-qualification questionnaires, including schemes like Constructionline and CHAS. This is no longer just a regulatory requirement; it is a commercial one.
Supply chain transparency. Under evolving sustainability reporting requirements, organisations are increasingly expected to evidence their waste supply chain, not simply declare it. Auditors want records, not assurances.
Register consolidation discussions. DEFRA and devolved authorities have discussed potential register interoperability, but no unified system exists yet. Multi-register checking remains essential for any carrier operating across UK borders.
Frequently Asked Questions
Is it free to check a waste carrier licence in the UK?
Yes. All four UK waste carrier registers are publicly accessible at no cost. CarrierCheck provides free single lookups and offers subscription plans for businesses that need bulk checks, monitoring, and documented audit trails.
What is the format of an EA waste carrier registration number?
England Upper Tier registrations typically begin with CBDU followed by six digits (e.g. CBDU123456). Some older registrations use prefixes such as EAWML or WCB. If you are unsure of the number, search by company name.
Can I search by company name rather than registration number?
Yes. Both the EA register and CarrierCheck support name-based searches. Registration number lookups are faster and more precise, but a name search works well when you do not have the number to hand.
Do I need to check even if the contractor holds an environmental permit?
Yes. A waste management licence or environmental permit covers facility operations such as treatment or disposal. It does not replace the requirement for a separate waste carrier registration covering transport. Always verify both where applicable.
What if the company name on the register does not match their invoice?
The contractor may be trading under a name that differs from their registered legal entity. Ask them to confirm the registered legal name and re-run the check using that. If there is still a mismatch, do not proceed until it is resolved in writing.
How often should I re-check carrier registrations?
As a minimum: before every new contract, and every six months for ongoing suppliers. Upper Tier registrations expire every three years, but revocations can happen at any time without warning.
What is the difference between a waste carrier and a waste broker?
A waste carrier physically transports waste. A waste broker arranges waste management on behalf of others without handling it directly. Brokers also require registration and appear on the same registers. If you use a broker to arrange collections, verify both their registration and that of the carrier they engage.
Summary
Checking a waste carrier licence in the UK is a straightforward legal requirement that every business producing or handling controlled waste must meet. The process in 2026 is:
- Get the carrier's registration number before any waste is collected
- Search the relevant register, or use CarrierCheck to cover all four at once
- Confirm the registration is Active, Upper Tier, and matches the entity on your contract
- Record the result with a timestamp
- Re-check every six months and monitor for expiry or revocation
Done properly, this takes five minutes and protects your business from fines, prosecution, and clean-up liability. Done poorly, it is one of the most avoidable and expensive compliance failures a UK business can make.
