UK packaging producers face higher costs and tighter reporting from 1 January 2026 as ministers update the Extended Producer Responsibility regime. The amendment to the 2024 regulations, made on 17 December 2025 and published on legislation.gov.uk, applies UK‑wide and focuses on fees, data integrity and what happens during mergers or brand transfers.

Fees rise across the schedule. The headline large‑producer registration increases from £2,620 to £2,842 (about 8.5%). Reprocessor registration moves to £3,228 and exporter registration to £574, with several smaller line items up more than 20%. Annual inflation uplifts now kick in from 2027 rather than 2026, so a further adjustment is already signposted.

A new closed loop category rewards genuine take‑back and recycling of food‑grade plastic packaging. To count, waste must be the producer’s own household packaging collected directly from consumers, kept segregated, and recycled by a single accredited reprocessor into food‑grade material. Evidence must be retained for seven years and must come from an accredited reprocessor or exporter.

The incentive is financial as well as environmental. Reported closed loop tonnages can be offset against the weight used to calculate disposal fees, but only if the producer pays an additional registration charge of £2,548. Report the data without paying and it becomes an offence; do not pay and the scheme administrator will ignore the offset when setting fees.

The scheme administrator also gains a late‑assessment power. If a business should have been treated as a liable producer, fees can be raised retrospectively using the best available estimates. There is a four‑year look‑back, extended to ten years where the producer (or its agent) failed to comply, and interest may be charged from the date payment would originally have fallen due.

Mergers get specific rules. Where companies combine, the new corporate body inherits outstanding producer obligations for the merger year and earlier years, can use any PRNs/PERNs already purchased, and must register by the earlier relevant date or within 28 days of completion. If any merging entity was large, the combined business is treated as large for the merger year and the following year.

Brand or business transfers carry heavier duties. The buyer must tell the agency within 28 days, register or re‑register if its status changes, and for the transfer year and the next two years is treated as large if its adjusted turnover and packaging tonnage exceed the thresholds. Recycling obligations move from seller to buyer and data for two half‑year periods must be resubmitted so fees reflect the new owner.

Material definitions tighten the reporting. Paper or board now includes some laminate packs if plastic is no more than 5% by mass; anything heavier sits in a fibre‑based composite category. Packaging that is part of a deposit return scheme-or would be but for a low‑volume line exemption-is treated as exempt packaging for EPR purposes.

Charities are no longer outside the regime in full. They remain exempt from producer obligations and annual fees, but charities acting as reprocessors or exporters must register from 1 October 2026 ahead of enforcement on 1 January 2027. Until then, related offences and civil sanctions are paused for charities in those roles.

Fee modulation sharpens the design signal. When setting household packaging disposal fees the administrator can now reflect whether a product uses no more material than is reasonably necessary for its purpose. In plain terms: right‑sized, simpler packs should cost less; over‑engineered formats will push charges higher.

Governance changes mean producers may deal with new counterparties. The scheme administrator can appoint one or more not‑for‑profit Producer Responsibility Organisations to run parts of the system. To protect continuity, data, IP, IT systems, contracts and even staff can be transferred to a successor PRO or back to the administrator if an appointment ends.

Transitional options are designed to clean up 2024–25 data. Large producers may amend earlier reports to recognise qualifying take‑back tonnages or to re‑allocate fibre‑based composite versus paper/board under the new definitions. Deadlines matter: amended 2024 data is due by 28 January 2026; amendments for the six months to 30 June 2025 are due by 1 April 2026. For the half‑year to 31 December 2025, qualifying take‑back cannot be reported as closed loop but may be included as relevant packaging. A £2,548 charge applies to these amendments.

Finance teams have a tight January window. By 28 January 2026, decide whether to pay the additional registration charge to access closed loop offsets for 2026, settle any amendment charges, and line up evidence from accredited reprocessors. M&A teams should add EPR clauses covering data resubmission, fee liabilities and PRN/PERN transfers into any deal completing from 1 January.

For SMEs the practical playbook is simple: review your status under the updated large/small tests, refresh packaging category mappings against the 5% plastic rule, and scenario‑test 2026 disposal fees with and without closed loop offsets. The instrument’s detail sits on legislation.gov.uk; the commercial impact will sit squarely in 2026 budgets.
