UK Proposes New and Amended Designated Standards Notices of Publication

The UK designated standards lists are being updated again. The Office for Product Safety and Standards (OPSS) maintains a GOV.UK guidance page, Designated standards: new or amended notices of publication, which sets out proposed updates to the lists of standards businesses can use to show compliance with Great Britain law requirements. Current entries on that page include proposals to amend the designated standards for machinery and for personal protective equipment, both dated 7 May 2026, with publication of the resulting notice scheduled for 5 June 2026.

Designated standards are the UK equivalent of EU harmonised standards. Where a manufacturer applies a designated standard in full, the product benefits from a presumption of conformity with the corresponding essential requirements in the relevant Great Britain product safety regulations — the same legal mechanism that harmonised standards provide under EU law, but operated under domestic legislation and published by notice rather than in the Official Journal of the European Union.

The practical consequence is that the designated standards list is not reference material. It is the document that determines whether your technical file still supports the UKCA marking you have already affixed. When a standard is withdrawn from the list, or superseded by an amended version with a cut-off date, the presumption of conformity attached to the older version ends on that date. Products assessed against the superseded version do not automatically become unsafe, but the manufacturer loses the shortcut and must demonstrate conformity by other means.

OPSS has been running this process since the end of the transition period. The pattern of sectoral updates is well established: in June 2022 OPSS published a list of proposed standards updates covering General Product Safety, Machinery, Low Voltage / Electrical Equipment Safety and Radio Equipment. The May–June 2026 proposals continue that cycle.

The GOV.UK guidance page lists proposals to amend by sector. Two are explicitly dated 7 May 2026, with the notice scheduled for publication on 5 June 2026:

Further proposal documents published through the same route cover low voltage equipment and construction products. The PPE proposal is circulated as a departmental PDF carrying the reference ds-0142-26-ppe-proposal-to-amend, and amends the published standards list for PPE.

The low voltage notices of publication are issued in support of the Electrical Equipment (Safety) Regulations 2016, and the designated standards pages for that sector are maintained separately on GOV.UK.

The individual standard reference numbers, the specific EN/BS designations being added, amended or withdrawn, and any dates of cessation of presumption of conformity are contained in the proposal PDFs themselves and in the subsequent notices of publication. Those details are not reproduced in the GOV.UK summary pages and are not stated here; read the sector PDF for your product category rather than relying on a secondary summary.

OPSS publishes a notice of proposal first, then the notice of publication. The proposal stage exists so that manufacturers, importers, authorised representatives, approved bodies and test houses can see which standards the Secretary of State intends to designate, amend or withdraw before the change takes legal effect. Only the notice of publication creates or removes the presumption of conformity.

That sequencing is the operative point for planning. A proposal dated 7 May 2026 with a notice scheduled for 5 June 2026 gives roughly four weeks between visibility and effect — enough time to check your standards register, not enough time to complete retesting if a standard you rely on is being withdrawn without a transitional cut-off.

On the face of the GOV.UK guidance page, the live proposals affect machinery, personal protective equipment, low voltage electrical equipment and construction products placed on the Great Britain market. The sectoral scope of OPSS designated standards activity more broadly also covers general product safety and radio equipment.

Anyone UKCA marking machinery or PPE should treat the 5 June 2026 notice as a scheduled compliance event. Anyone relying on the Electrical Equipment (Safety) Regulations 2016 route for low voltage products should monitor the low voltage designated standards page separately, because that sector has its own proposal document and its own publication timing.

Northern Ireland is not covered by these lists. Designated standards apply to Great Britain; goods placed on the Northern Ireland market continue to follow the applicable EU rules and the UKNI marking regime where a UK conformity assessment body has been used.

Functionally they do the same job: both confer presumption of conformity. The differences are institutional. Harmonised standards are cited in the Official Journal of the European Union under the relevant EU legislation; UK designated standards are published by notice on GOV.UK under the corresponding Great Britain regulations. The two lists have largely overlapped in content since 2021, but they are maintained by different authorities on different timetables, which means a standard can be cited in one jurisdiction and not yet in the other. Do not assume that because a revised EN version has been cited in the Official Journal it is automatically designated in Great Britain, or vice versa.

Pull the machinery and PPE proposal PDFs from GOV.UK now and compare them line by line against your standards register. For machinery, check every standard cited in your Annex-equivalent technical documentation; for PPE, check the ds-0142-26 proposal against the declarations of conformity for each category of equipment you place on the GB market.

Where a standard you rely on appears in the amendment list, establish three things: whether the new version is a technical revision or editorial, whether the notice sets a date on which presumption of conformity under the superseded version ceases, and whether your approved body needs to review the file. For PPE Category III and for machinery in Schedule 2 / Annex IV-equivalent categories, an approved body involvement means the certificate holder — not just the manufacturer — must act.

If retesting is required, book it on the proposal, not on the notice. Test house capacity for machinery safety and PPE performance testing does not expand because a notice was published.

Finally, subscribe to email alerts on the GOV.UK designated standards pages for every sector you place products under, and record the designated standards list version used in each technical file. When market surveillance asks which version of a standard supported your declaration, the answer needs to be in the file, not reconstructed afterwards.

5 June 2026 — scheduled publication of the notices for machinery and PPE. Check the GOV.UK designated standards pages that day and reconcile the final notice against the 7 May 2026 proposal, since proposals and final notices do not always match. Separately, track the low voltage and construction products proposals, which run on their own timetables.
