UKCA mark vs CE mark — post-Brexit clarity 2025-2026

Brexit was supposed to bring a clean break from CE marking and a shiny new UKCA mark for the Great Britain market. Reality bit harder. After multiple deadline extensions and an August 2023 ministerial announcement, the UK formalised the new settlement in the Product Safety and Metrology etc. (Amendment) Regulations 2024, made on 23 May 2024 and in force from 1 October 2024. The practical effect: for most CE-marked goods you already sell into the EU, you can keep using the CE mark on the GB market without re-certifying. UKCA is still legally available — it is just rarely the cheaper path.

This article walks through the current 2025-2026 landscape: where CE is accepted in GB, where UKCA is still needed, what the Windsor Framework means for Northern Ireland, and the deliberately separate timelines for construction products and medical devices.

The 2024 reset: indefinite CE recognition in Great Britain

Between Brexit (1 January 2021) and mid-2024 the UK ran a moving-target regime: time-limited acceptance of CE marking with repeatedly extended sunset dates. That changed when SI 2024/696 was made on 23 May 2024 and came into force on 1 October 2024.

The instrument amends the underlying UK product regulations to permit, on a permanent basis, conformity demonstrated through the EU procedure (CE marking, EU-recognised notified body involvement where required, EU declaration of conformity) as a route to placing goods on the GB market. Per the gov.uk guidance, "the UK continues to recognise the CE marking, alongside or in place of the UKCA marking, for the Great Britain market" under this 2024 legislation.

Which product regulations are covered

SI 2024/696 amends roughly 21 sets of GB regulations. The headline ones include:

For any of these, a product that bears a valid CE mark, has a current EU declaration of conformity, and (where required) was assessed by an EU-recognised notified body can be placed on the GB market without separate UKCA marking. Technical documentation must still be available in English on request from market surveillance.

Fast-track UKCA

For manufacturers who actively want a UKCA mark — perhaps to show a UK identity, or because a buyer specifies it — gov.uk's placing manufactured goods on the market guidance describes a "fast-track UKCA" route: meet the EU requirements with an EU conformity assessment, then issue a UK declaration of conformity and affix UKCA. No second test campaign, no parallel UK approved body.

Northern Ireland under the Windsor Framework

Northern Ireland sits inside the EU goods regime under the Windsor Framework. The marking rules there are different from GB:

• Goods placed on the NI market with conformity assessment by an EU-recognised notified body carry the CE mark only.
• Goods placed on the NI market with conformity assessment by a UK-based notified body carry the CE mark plus the UK(NI) marking next to it. The UK(NI) mark cannot be used on its own and is not valid for the EU/EEA market.
• Qualifying Northern Ireland goods can move from NI into Great Britain with unfettered access. They do not need to be re-marked with UKCA.

This effectively gives NI manufacturers a single conformity path (CE, or CE + UK(NI) if using a UK body) that works for the NI market, the EU/EEA, and — via unfettered access — for GB too.

Where UKCA is still effectively required

Indefinite CE recognition under SI 2024/696 does not cover everything. A handful of sectors are governed by separate, sector-specific regimes with their own UK marking rules and timelines.

Construction products

Construction products are not under SI 2024/696. They fall under the UK retained version of the EU Construction Products Regulation. Per the gov.uk construction products regulation in Great Britain guidance: "The CE mark will continue to be available when placing construction products on the market in Great Britain." A UKCA mark is also available, with testing through a UK approved body. The longer-term framework is "conditional on wider reforms" — meaning the post-Grenfell construction product safety review.

Medical devices

Medical devices follow the Medical Devices Regulations 2002 (SI 2002/618, as amended). They have their own transitional CE recognition windows on the GB market:

• Devices certified under the EU MDD or AIMDD: CE mark accepted until 30 June 2028 or certificate expiry, whichever is sooner.
• Devices certified under EU IVDR or MDR: CE mark accepted until 30 June 2030.
• IVDs certified under the EU IVDD: CE mark accepted until 30 June 2030 or certificate expiry, whichever is sooner.

The UK government has announced it will consult on indefinite CE recognition for medical devices, but until that consultation closes and is legislated, the dates above are the operative deadlines.

Other sector-specific carve-outs

The gov.uk guidance explicitly directs manufacturers to separate guidance for:

• Civil explosives (Explosives Regulations 2014, as amended)
• Rail products (rail interoperability rules)
• Marine equipment (Merchant Shipping (Marine Equipment) Regulations 2016)
• Transportable pressure equipment (TPE Regulations 2009, as amended)
• Unmanned aircraft systems (CAA regimes)

For each of these, do not rely on the general SI 2024/696 indefinite CE recognition. Check the sectoral page.

The practical decision tree for 2025-2026

For a typical CE-marked electronics product (say, a connected sensor with WiFi/BLE):

1. Goods for the GB market only: Keep the CE mark. Hold the EU DoC and technical file. You're compliant under SI 2024/696. UKCA is optional.
2. Goods for the NI market: Keep CE. If conformity assessment was done by a UK-based notified body, add UK(NI) next to CE.
3. Goods for both NI and GB: Same as NI — qualifying NI-placed goods move into GB unfettered.
4. Construction products: Read the dedicated Construction Products Regulation guidance; both CE and UKCA still accepted but reform is pending.
5. Medical devices: Plan for the 2028 / 2030 deadlines unless and until the indefinite recognition consultation lands.

Common mistakes

• Treating SI 2024/696 as a "blanket" replacement for UKCA. It covers a defined list of ~21 product regulations. Construction products, medical devices, rail and marine sit outside that list.
• Forgetting to keep the English-language technical file available. Indefinite CE recognition is not a paperwork holiday — UK market surveillance can still demand the technical file and DoC in English.
• Using a UK(NI) mark on the EU/EEA market. UK(NI) is valid only for NI placement when a UK-based notified body has done the assessment. It does not work in Ireland, France, Germany, etc.
• Assuming UKCA still has a hard deadline. Older blog posts and consultancy decks reference 2023/2024/2025 deadlines for mandatory UKCA — most of those have been overtaken by SI 2024/696.
• Confusing medical device transitional dates with general CE recognition. The medical device 2028 / 2030 dates do not apply to EMC, RED or RoHS products.

How Cenitia helps

Cenitia generates a single EU technical file and Declaration of Conformity that, post-SI 2024/696, is also your GB compliance package for the in-scope regulations — you do not need to redo conformity assessment to enter the UK market. The platform tracks the UK-specific carve-outs (construction, medical devices, civil explosives, rail, marine) and flags them when a manufacturer's product classification lands in one of those sectors, so you know to follow the dedicated UK regime rather than the general indefinite-recognition route.

Our regulation watcher monitors UK Statutory Instruments and gov.uk guidance pages. If the medical device CE recognition consultation results in new legislation, or if Westminster amends SI 2024/696, your DoCs are flagged for review automatically.

Frequently asked questions

Do I still need a UKCA mark to sell into Great Britain in 2026?

For most of the 21 product regulations covered by the Product Safety and Metrology etc. (Amendment) Regulations 2024 (SI 2024/696), no — the UK government recognises CE marking indefinitely on the GB market. UKCA remains optional and is still required for a few sectors (construction products, certain medical devices, rail interoperability, civil explosives, marine equipment). See the gov.uk guidance "Placing manufactured goods on the market in Great Britain".

What is the difference between the UKCA, CE and UK(NI) marks?

CE is the EU's conformity mark for goods placed on the EU/EEA single market. UKCA (UK Conformity Assessed) is the Great Britain equivalent introduced after Brexit. UK(NI) is used in Northern Ireland alongside a CE mark when a UK-based notified body has done the conformity assessment — required because NI follows EU goods rules under the Windsor Framework.

When does CE recognition for GB expire?

It does not. SI 2024/696, in force from 1 October 2024, made CE recognition indefinite for the regulations it amends (EMC, RED, RoHS, Toy Safety, Machinery, PPE, gas appliances, pressure equipment, lifts, and others). The previous time-limited transitional regime was replaced. Construction products and medical devices follow separate, sector-specific timelines.

Can I use CE marking for construction products sold in GB?

Yes — under separate sectoral guidance the CE mark continues to be accepted for construction products on the GB market, alongside the UKCA option, but the longer-term framework is conditional on wider construction product reform following the Grenfell inquiry. See the gov.uk "Construction Products Regulation in Great Britain" guidance.

What about medical devices?

Medical devices follow the Medical Devices Regulations 2002 (SI 2002/618) and have their own transitional CE recognition: MDD/AIMDD devices until 30 June 2028, EU IVDR/MDR devices and IVDD devices until 30 June 2030, in each case or certificate expiry whichever is sooner. The UK government has announced it will consult on indefinite CE recognition for medical devices.

If I sell into Northern Ireland, what mark do I use?

Goods placed on the NI market follow EU rules. A CE mark alone is sufficient if conformity assessment was done by an EU-recognised notified body. If a UK-based notified body did the assessment, you must also apply the UK(NI) marking next to the CE mark. Qualifying NI goods can move into Great Britain with unfettered access under the Windsor Framework.
