UKCA vs CE marking in 2026: what GB requires

The short answer: in Great Britain, CE is usually enough

Most of what is written about UKCA on the web is stuck in 2022-2023, when the mark was scheduled to become mandatory and every deadline was about to bite. That is not the 2026 position. The Product Safety and Metrology etc. (Amendment) Regulations 2024 (SI 2024/696), in force from 1 October 2024, deleted the sunset date from CE recognition across the main product-safety and metrology regimes. GOV.UK now states the position plainly: the UK continues to recognise the CE marking, alongside or in place of the UKCA marking, for the Great Britain market. There is no replacement deadline published for those regimes — recognition is open-ended, which the Department for Business and Trade and most trade bodies describe as indefinite.

So for a typical seller — a private-label brand shipping toys, consumer electronics, a Bluetooth speaker, a power tool, a pair of safety gloves — a product lawfully CE-marked for the EU can go on the Great Britain market as it is: no second conformity assessment, no UK Approved Body certificate, no separate UK declaration of conformity, no UKCA mark. Nothing forces you to stop using UKCA either; it remains a fully valid route, and both marks may sit on the same product.

Two caveats keep this honest. Indefinite means no published end date, not a guarantee: the Product Regulation and Metrology Act 2025 (in force 21 July 2025) is an enabling act letting ministers change product rules — aligning with or diverging from EU law — through secondary legislation. And the CE route means meeting EU requirements, not UK ones: if the EU tightens a harmonised standard, the product you sell into GB has to keep up with the rules it claims conformity with. This is a market-access shortcut, not a compliance holiday.

The 21 regulations where CE is accepted with no end date

SI 2024/696 amends a defined list of product regulations, and that list is the real scope of open-ended CE recognition in Great Britain. The table below reproduces it, plus the sectors that sit outside it and keep their own rules — checked 2026-08 against legislation.gov.uk and the two GOV.UK marking guidance pages, both last updated 7 April 2026.

Read it one way: if your product falls under a regulation in the top block, a CE mark backed by a valid EU conformity assessment is sufficient for Great Britain and there is nothing further to do on marking. If it falls in the bottom block, stop and read the sector rules — those are the places where a date or a different mark can catch you.

Note what is on neither list. Regimes that never used CE marking — general product safety under the General Product Safety Regulations 2005, textile labelling, food contact materials, chemicals under UK REACH — are unaffected by all of this. UKCA never applied to them, so 'do I need UKCA?' is the wrong question for those products.

The real exceptions: medical devices and the sector carve-outs

Medical devices are the clearest place where a deadline still exists. CE-marked devices are accepted on the Great Britain market on transitional terms, and the MHRA's timelines publication (last updated 16 February 2026) sets them out: general medical devices compliant with the EU MDD or AIMDD may be placed on the GB market until the sooner of certificate expiry or 30 June 2028; IVDs compliant with the EU IVDD until the sooner of certificate expiry or 30 June 2030; and general medical devices (including custom-made devices) under the EU MDR, and IVDs under the EU IVDR, until 30 June 2030. Class I devices self-declared under the EU MDR run to 30 June 2030, while Class I devices self-declared under the old MDD — including up-classified devices and reusable surgical instruments — sit on the 30 June 2028 date. You cannot rely on an expired certificate.

Those dates are live policy, not settled law. The MHRA ran a targeted consultation on indefinite recognition of CE-marked devices from 16 February to 10 April 2026, which floated removing the sunsets entirely and aligning GB timelines with the EU's. As checked 2026-08 the statutory 2028 and 2030 dates still stand on GOV.UK, so plan against them and treat any extension as upside rather than assumption. Separately, a non-UK device manufacturer must appoint a UK Responsible Person and register with the MHRA before placing devices on the GB market — that obligation exists regardless of which mark the device carries.

Construction products are the second exception, and the one most often reported wrongly. The 30 June 2025 cliff-edge was withdrawn by a written ministerial statement on 2 September 2024, and the CE route has continued since: the Construction Products (Amendment) Regulations 2025 (SI 2025/1172), in force 8 January 2026, made the technical amendments needed so that products CE-marked under the new EU Construction Products Regulation (EU) 2024/3110 can still be sold in Great Britain without retesting or an additional mark. The UK mark remains available too. But GOV.UK's construction-products guidance is more conditional than the SI 2024/696 wording — it ties the longer-term future of CE marking to wider construction-product reforms — so read it as 'no end date today, policy review pending', with any change expected to come with a transition period rather than overnight.

The remaining carve-outs are narrower but absolute: marine equipment, rail products, cableways, transportable pressure equipment and uncrewed aircraft systems each have their own UK regime, and several use a different mark rather than UKCA. If your product is in one of those, the general CE-recognition rule does not decide the question for you.

Northern Ireland: CE or CE plus UKNI, never UKCA alone

Northern Ireland is not covered by any of the above. Under the Windsor Framework, goods placed on the Northern Ireland market must meet EU product rules, so the marking is the CE marking. A UKCA mark on its own has no legal effect in Northern Ireland — GOV.UK's guidance (last updated 8 April 2026) is unambiguous that UKCA alone is not a valid route there.

The UKNI marking is the one Brexit-era mark most sellers misunderstand. It is not an alternative to CE and it is never used on its own: it always accompanies an EU conformity marking. You need it in exactly one situation — where your product requires mandatory third-party conformity assessment and you chose a UK-based body to do it. Then the product carries CE and UKNI together. Use an EU notified body instead, or self-assess where the regulation allows it, and plain CE is correct with no UKNI at all.

The trap runs the other way: a CE plus UKNI product cannot be placed on the EU market, so using a UK body for third-party assessment fragments your inventory if the same stock serves Ireland and Northern Ireland. Routing assessment through an EU notified body instead gives you one CE-only SKU for the EU, Northern Ireland and — given open-ended recognition — Great Britain too.

Dual marking, labels and the 31 December 2027 date

Dual marking is expressly allowed. GOV.UK states that a product can carry multiple markings, including UKCA and CE, provided it complies with the relevant requirements for each and the markings can be clearly seen — no rule against both on the same moulding, no requirement that one be larger. But each mark needs its own conformity assessment and its own declaration of conformity: UKCA asserts conformity with GB legislation, CE with EU legislation, and the two declarations stay separate documents even where the technical file behind them is identical.

Where the UKCA mark is used, the mechanics are the familiar ones: standard recognisable form, scaled proportionately against the official templates, at least 5mm high unless the specific regulation sets another minimum, and easily visible, legible and indelible.

One date is worth diarising. Legislation currently in force allows the UKCA marking to sit on a label affixed to the product, or on an accompanying document, until 11pm on 31 December 2027; after that it goes on the product itself. The same cut-off applies to the importer-details easement, under which the GB importer's name and address may be given somewhere other than on the product for goods imported from an EEA state (and in some cases Switzerland). For UKCA-marked goods that is a tooling and artwork deadline, not a paperwork one — and tooling takes longer than most sellers plan for.

UK Approved Body, EU Notified Body, and who must be UK-based

The certification bodies do not cross the border. A conformity assessment body designated for the Great Britain market is a UK Approved Body, accredited by UKAS and listed in the UK Market Conformity Assessment Bodies (UKMCAB) database on GOV.UK — the UK counterpart of the EU's NANDO — and its certificates support UKCA only. An EU notified body, listed in NANDO, supports CE only. Since 1 January 2021 neither can do the other's job. If a supplier offers you a single certificate covering both marks, check that supplier very carefully.

On people rather than paperwork: for the 21 regulations above there is no general 'UK Responsible Person' equivalent to the EU's GPSR responsible person. The obligations land on the GB importer — verifying the manufacturer's conformity assessment, keeping the declaration of conformity, and putting its own name and contact address on the product or its packaging — and some regimes let a non-UK manufacturer appoint a UK Authorised Representative to hold documentation and act on its behalf.

The term UK Responsible Person is specific to two regimes and using it loosely causes real mistakes. Medical devices: a manufacturer outside the UK must appoint a UK Responsible Person, who needs written authority from the manufacturer, and whose name and address must appear on the labelling, packaging or instructions for use of a UKCA-marked device; MHRA registration is required before the device is placed on the GB market. Cosmetics: the UK Cosmetics Regulation requires a UK-based Responsible Person, overseen by OPSS. If you sell neither, you need an importer or an authorised representative, not a UK Responsible Person.

So should you bother with UKCA at all?

For most sellers in 2026, no. If you already hold a valid EU conformity assessment for a product in the SI 2024/696 list, adding UKCA duplicates cost — a UK Approved Body fee where third-party assessment is required, a second declaration of conformity, new artwork and tooling — for zero additional market access. The rational default is CE only, one SKU, one technical file.

Three cases still earn it. First, the carve-out sectors, where the GB regime rather than CE recognition decides what you need. Second, where a large GB customer or a public-procurement specification asks for UKCA contractually — buyers can demand more than the law does, and arguing costs more than complying. Third, as insurance against future divergence under the Product Regulation and Metrology Act 2025; any change would come with notice, so that is a considered decision, not an urgent one.

Either way, answer the underlying question before the marking question: which directives or regulations actually apply to your product, and does any of them require a third-party body at all. That is where the real cost and risk sit — the mark itself is the last five per cent. The three tools below cover applicability, the directive mapping and the UKCA-versus-CE decision for your specific product and markets.
