In an update published on GOV.UK, PackUK said it is introducing a 1 September 2026 resubmission deadline for 2025 packaging data from producers that pay pEPR fees. The change is being made on behalf of all four UK nations and applies to the data set that will feed into Year 2 charging under the packaging extended producer responsibility regime. For affected businesses, the announcement is less about a new reporting duty than about fixing a final correction point. It sets a clear administrative date by which errors in 2025 submissions need to be amended if those changes are to be reflected in fee calculations later in 2026.
PackUK said the deadline gives producers a five-month correction window after the main 1 April 2026 reporting deadline. During that period, businesses can review submitted packaging data, identify inaccuracies and send corrected figures back into the system. That timetable is intended to reduce repeated recalculations. In practical terms, the policy creates a defined period for data cleaning before PackUK moves from provisional reporting into confirmed charging, with the stated aim of allowing fees and Notices of Liability to be issued later in the year without further expected revisions.
After 1 September 2026, regulators will continue compliance monitoring, but PackUK said subsequent data resubmissions will no longer affect disposal fees or Notices of Liability. The organisation will instead use the data position as at that deadline to publish confirmed producer fees for 2026/27 and to issue the formal liability notices later in 2026. This is the most significant operational point in the update. Up to the deadline, corrected data can still change the charging outcome. After the deadline, corrections may still be required for compliance purposes, but they will not reopen the fee-setting process for Year 2.
PackUK also confirmed that it does not intend to publish any further illustrative fees before the final figures are issued. Illustrative Year 2 fees were published in December 2025, but the body said those figures remain subject to change until the final resubmission cycle has closed. For producers, that means planning assumptions should now be based on the expectation of one final fee publication later in 2026 rather than a further round of indicative updates. For local authorities, the same approach is designed to provide more certainty over expected pEPR income, which has been a recurring concern in the early stages of scheme implementation.
The immediate action for producers is straightforward. Any business that needs to correct its 2025 packaging data should do so by 1 September 2026. Where reporting is handled through a compliance scheme, PackUK said producers should contact that scheme directly to confirm what information is required and the internal deadline for submitting changes. The update also draws an important distinction between charging and compliance. After 1 September 2026, producers must still resubmit data where necessary so that records remain as accurate as reasonably possible for recycling obligations, even though those later corrections will no longer change Year 2 disposal fees or Notices of Liability.
Payment terms will remain aligned with the first year of the scheme. PackUK said producers will have 50 calendar days to pay once Notices of Liability are issued, and instalment payments will continue to be available. The wider policy objective, as set out by PackUK earlier in 2026 and repeated in this notice, is to improve data stability and reduce in-year fee variability so businesses can plan with more confidence. The same approach is intended to give local authorities greater certainty over pEPR payments.
