AATF (Approved Authorised Treatment Facility)
AATF is one of those acronyms that appears on quotations for IT disposal without ever being explained. It matters because it marks the difference between a site that is merely permitted to handle electrical waste and one that can generate the evidence the WEEE system runs on. For a business disposing of its IT estate, the distinction is the difference between a disposal route that produces usable proof and one that does not. This guide sets out what the approval is, who grants it, and what it does and does not tell you about the operator you are dealing with.
What is an AATF?
An AATF is an approved authorised treatment facility: a site holding the environmental permit needed to treat WEEE which has also applied for and received approval from its environmental regulator. The approval sits on top of the permit rather than replacing it.
The two-stage structure is deliberate. The permit addresses whether the site can handle the waste safely and lawfully; the approval addresses whether it can be trusted to issue evidence into the national WEEE system. A site can lawfully treat electrical waste without ever seeking approval — it simply cannot issue evidence notes. That is why the acronym appears in procurement conversations: it is shorthand for "this route generates evidence", not merely "this site is legal".
How does an AATF differ from an ATF?
One letter, one capability. An authorised treatment facility is licensed to treat WEEE; an approved authorised treatment facility is additionally approved to issue WEEE evidence notes.
| ATF | AATF | |
|---|---|---|
| Permitted to treat WEEE | Yes | Yes |
| Approved by the environmental regulator | No | Yes |
| Can issue WEEE evidence notes | No | Yes |
| Approval renewed annually | Not applicable | Yes |
Whereas a permit runs until varied or surrendered, approval is applied for each year, so an operator's AATF status is a current fact rather than a permanent attribute. GOV.UK sets out the process in its guidance on WEEE reuse and treatment.
What are WEEE evidence notes?
Evidence notes are the records proving that WEEE was reused or treated. They are issued by AATFs — and, for whole appliances sent abroad, by approved exporters — and are raised on the WEEE Online system.
Their purpose is upstream rather than downstream: evidence notes let producer compliance schemes demonstrate that the tonnages their members were responsible for have actually been handled. A business disposing of equipment does not usually receive an evidence note and does not need one. What the business receives is the transfer document for the collection and, where relevant, destruction evidence for the data. The evidence note operates in a different part of the system, which is why asking for one is often a sign that the wrong document is being requested.
Who grants AATF approval?
The environmental regulator of the UK country in which the site is located. For a facility in England that is the Environment Agency; the other UK nations have their own regulators, and approval follows the site rather than the operator.
Because approval is annual, it also has a deadline attached: GOV.UK states that an operator wanting approval to run from 1 January must apply by 30 September of the preceding year. The practical implication for anyone buying disposal services is that AATF status should be treated as something to confirm currently rather than assume from a logo on a quotation, in the same way a waste transfer note records a carrier registration number that can be checked against a public register.
Does an AATF handle data destruction as well?
Not as part of the approval. AATF status concerns environmental treatment of the equipment; it carries no assurance whatsoever about the information stored on it.
The two are routinely conflated in procurement because both happen after the van leaves, but they answer to different regulators and generate different documents. Environmental treatment is evidenced through the WEEE system; data destruction is evidenced by a certificate of data destruction issued by whoever performed the erasure or destruction, and it is the Information Commissioner's Office rather than the Environment Agency that takes an interest. Many approved facilities do offer data destruction as a commercial service alongside treatment — but where they do, that capability rests on their own processes and any destruction standard they work to, not on the AATF approval itself. Ask about it separately.
What happens to equipment once it reaches an approved facility?
Depollution comes first. Hazardous components are removed before the equipment is broken down any further, which is why classification at the collection stage matters to what happens at the far end.
After depollution the equipment is separated into material streams — metals, plastics, circuit boards, cabling — for recovery, with items suitable for reuse diverted before destructive processing where that route is available. This ordering explains a detail that otherwise looks arbitrary: why display devices containing POPs are treated as hazardous and travel on a consignment note rather than a waste transfer note. The classification is not paperwork for its own sake; it determines the handling the item receives on arrival, and a mis-declared load is a processing problem as well as a documentation one.
Does using an AATF make a disposal compliant?
Not on its own. Treatment at an approved facility addresses the WEEE side; it says nothing about how the equipment got there or what happened to the data on it.
Three obligations run in parallel and each needs its own evidence. The WEEE Regulations govern treatment and financing. The waste duty of care governs the transfer and requires a transfer document naming a registered carrier. UK GDPR governs the personal data on the devices and is unaffected by either, which is why a certificate of data destruction sits outside the environmental paperwork entirely. A disposal can satisfy one and fail another without any of the documents looking wrong.
What should a business ask about a treatment facility?
Four questions, all answerable in a sentence by an operator who has nothing to hide. Each maps to a document or a register entry rather than to a reassurance.
- Is the treatment site an AATF, and is the approval current? Approval is annual, so currency is the operative word.
- Who carries the equipment, and what is their registration number? Checkable against the Environment Agency public register before collection.
- Which document will I receive for the transfer? A transfer note, or a consignment note where the load is classified hazardous.
- Who issues destruction evidence for data-bearing assets? It should be whoever performs the destruction.
T&C Logistics occupies the carriage link in this chain, registered with the Environment Agency as an upper tier waste carrier, broker and dealer under number CBDU654368, with treatment at a partner-operated approved facility. See WEEE collection or get in touch to discuss a collection.
Related Questions
- Do I need to use an AATF to dispose of business computers?
- Business WEEE has to reach a site permitted to treat it, and in practice the routes offered commercially run through approved facilities because those are the sites that generate evidence for the wider system. From the disposing business's point of view the more useful question is whether the treatment destination is identified and its approval current, rather than whether the acronym appears in the quotation.
- Will I receive a WEEE evidence note for my collection?
- Usually not, and you generally do not need one. Evidence notes exist so producer compliance schemes can demonstrate the tonnages they are responsible for have been treated. The documents that matter to the disposing business are the waste transfer note or consignment note for the transfer, the asset list, and destruction evidence for data-bearing items.
- Can a waste carrier also be an AATF?
- The two authorisations are separate and are commonly held by different organisations, because they cover different activities: carriage requires registration with the environmental regulator, while treatment requires a permitted site that has additionally been approved. An operator holding both is possible, but a carrier registration on its own says nothing about treatment capability, and vice versa.
- How can I check whether a facility's AATF approval is current?
- Ask the operator to identify the treatment site and confirm the approval period, then keep that answer with the job record. Because approval must be applied for annually — GOV.UK sets a 30 September deadline for approval running from 1 January — a claim that was accurate last year is not automatically accurate this year, which is the specific trap with this credential.
- What happens to equipment that can be reused rather than recycled?
- Reuse is handled at approved facilities alongside treatment, and evidence for reuse is issued through the same approval. Reuse is generally the better outcome environmentally and can carry residual value, but it sharpens the data question, because equipment leaving in working order carries readable storage unless it has been erased to a verified standard first.
