A UK customer's compliance form lists UKCA marking as a requirement. A different buyer sends your CE documents back saying they stopped being valid after Brexit. Both are repeating something that was true at some point in the last five years and is not true now. The Great Britain position has been settled since 1 October 2024, and it is more permissive than most suppliers assume.
For the large majority of electronic products, CE marking on its own is enough to place goods on the market in Great Britain, with no expiry date on that arrangement. UKCA marking still exists, you can still use it, and in a few product categories you have to. For chargers, adapters, LED drivers, Bluetooth speakers and most other electronics, it is now a choice rather than an obligation.
Great Britain is not the United Kingdom
This is where most of the confusion starts, and it changes the answer completely.
- Great Britain is England, Scotland and Wales. It runs its own product rules, based on law retained at EU exit.
- The United Kingdom is Great Britain plus Northern Ireland. Northern Ireland continues to follow EU product rules under the Windsor Framework.
So when a buyer asks whether they need UKCA to sell in the UK, the useful first response is to ask where the goods are actually landing. A shipment to Belfast is not the same problem as a shipment to Birmingham, even though both are the UK.
Which mark, by destination
| Where the product is placed on the market | Mark the product needs |
|---|---|
| Great Britain - electronics covered by the recognised regulations (electrical safety, EMC and radio equipment among them) | CE marking is accepted indefinitely. UKCA is optional. |
| Great Britain - categories outside the recognition list | The relevant sector regime applies. Medical devices, construction products, rail products, marine equipment, cableways, transportable pressure equipment and uncrewed aircraft systems each follow their own rules. |
| Northern Ireland | CE marking, or CE together with UKNI marking where a UK approved body carried out mandatory third-party assessment. |
| European Union | CE marking. UKCA is not recognised in the EU. |
What actually changed, and when
If you were given a UKCA timeline in 2021 or 2022, it is out of date. Here is the sequence that matters.
| Date | What happened |
|---|---|
| 1 January 2021 | UKCA marking introduced. CE marking continued to be accepted in Great Britain on a transitional basis. |
| 2021 - 2022 | The end of that transitional period was moved, first to the end of 2022, then to the end of 2024. |
| August 2023 | The government announced that CE marking would be recognised indefinitely for most product categories. |
| 1 October 2024 | The Product Safety and Metrology etc. (Amendment) Regulations 2024 came into force. They removed the 31 December 2024 cut-off across 21 product areas, so the recognition no longer has an end date. They also updated recognition to follow the latest EU requirements rather than those frozen at the end of 2020, and introduced Fast-Track UKCA. |
| 21 July 2025 | The Product Regulation and Metrology Act 2025 came into force. It is a framework act, giving government powers to update product rules, to end or extend CE recognition in future, and to place new duties on online marketplaces once secondary legislation is made. It did not change the marking position when it commenced, and no secondary legislation has been made yet. |
| 31 December 2027 | If you use UKCA marking, the option to put it on a label or an accompanying document ends at 11pm on this date. From 1 January 2028 it normally has to be affixed to the product itself or its packaging. |
Two things are worth pulling out of that table. The recognition is open-ended rather than another extension with a date on it, so this is no longer a decision to revisit every year. And the 2027 date is not a CE deadline - it only affects products that have chosen the UKCA route.
Which electronics the recognition covers
The recognised set includes the regulations that decide most electronic hardware:
- Electrical Equipment (Safety) Regulations 2016 - the GB version of the low voltage directive
- Electromagnetic Compatibility Regulations 2016
- Radio Equipment Regulations 2017
- Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012
- Ecodesign requirements for energy-related products
Toys, machinery, personal protective equipment, gas appliances, pressure equipment, equipment for explosive atmospheres and measuring instruments are also inside the recognised group.
In practice a CE-marked switching adapter, LED driver, wireless camera or Bluetooth speaker can go onto the Great Britain market as it is. The same test reports support it, because GB designated standards mirror the EU harmonised standards and the 2024 regulations permit EU harmonised standards to be used where they are recognised. For how that splits out by product type, our product category pages set out the usual test scope for each.
When UKCA marking still matters
Three situations, and only the first one is legal.
1. Categories outside the recognition. Medical devices are handled by the MHRA on its own timetable: CE marking is currently accepted for devices certified under the older medical device directives until 30 June 2028 and for EU MDR and IVDR devices until 30 June 2030, with a consultation on indefinite recognition under way. Check current MHRA guidance rather than an older summary. Construction products have separate indefinite CE recognition announced in September 2024, and rail products, marine equipment, cableways, transportable pressure equipment and uncrewed aircraft systems follow their own sector rules too.
2. A commercial requirement. A UK retailer or a public tender can require UKCA in its purchasing documents. That is a condition of the contract rather than a legal obligation, but it still has to be met or negotiated - and the useful question is which regulations the customer actually wants evidenced, because the underlying test content is the same.
3. You simply prefer it. Some manufacturers want a UK approved body's name behind the product. That is a legitimate choice.
If you do go the UKCA route, Fast-Track UKCA is the detail to know: the marking can be applied where either the UK essential requirements or the recognised EU essential requirements are met. You do not have to run a second conformity assessment to produce the same evidence twice.
One thing not to mix: where a third party is involved, the four-digit number shown with the mark belongs to an EU notified body under CE and to a UK approved body under UKCA. The two are not interchangeable, and a product carrying an EU notified body number beside a UKCA mark is a finding waiting to happen.
The part that trips up shipments: who is on the label
Marking is the visible part of GB compliance. The obligations enforcement actually looks at sit on two parties.
The manufacturer's name and address must appear on the product. If the goods are brought into Great Britain by an importer, that importer's name and registered address go on the product as well. There is a labelling concession for goods imported from an EEA state or Switzerland before 31 December 2027, where the importer's details may sit on the packaging or an accompanying document instead - but the obligation itself does not disappear.
Two situations follow from this. If your GB customer acts as the importer, their details belong on the product, which is worth agreeing before artwork is printed rather than after. And if you sell direct to consumers in Great Britain with no GB importer in the chain, there is no GB contact on the label at all - exactly the kind of gap that surfaces in a marketplace review or at the border.
Alongside the label, the Declaration of Conformity and the technical documentation need to be in English, and technical documentation is typically retained for 10 years after each individual product is placed on the Great Britain market. Whether the report you already own still supports the claim you are making is a separate question, covered in how long a test report is valid.
Three situations that come up every week
A CE file that names the factory, not the brand. An overseas factory's existing CE report and declaration usually name the factory as the responsible manufacturer. That is workable for the EU and for Great Britain, because it is the factory's own evidence. It becomes a problem when the buyer needs the importing or branding entity to be the responsible party, because the declaration names somebody else. Check which entity is signing it before you promise a customer a document set - changing that is paperwork, not testing.
A buyer asking for a UKCA certificate. Procurement portals routinely list a UKCA certificate among required uploads. For a product that is self-declared rather than third-party certified, there is no such certificate to produce, in the same way there is no single CE certificate for a charger. What exists is the test report, the Declaration of Conformity and the technical file. Some buyers accept a short written note on the current GB position alongside those documents; some hold to their own form. Either way, finding this out before the shipment date is cheaper than finding out at the port.
Great Britain and Northern Ireland in one order. A distributor with customers on both sides of the Irish Sea can order one model for two destinations. The two parcels need different documentation streams: the Great Britain parcel relies on CE recognition, the Northern Ireland parcel sits under EU rules, and where a UK approved body carried out mandatory third-party assessment, the UKNI marking appears on that batch only. Splitting the paperwork at the order stage is straightforward. Reconstructing it after the pallets are mixed is not.
Mistakes worth avoiding
| Mistake | What it costs |
|---|---|
| Commissioning a UKCA test programme for a product that already holds CE evidence in the recognised categories | A second assessment for the same standards, when nothing in the GB rules required it. |
| Working from a 2021 or 2022 UKCA timeline | A stalled or re-routed shipment for a rule that stopped applying in October 2024. |
| Treating the UK as one market | Northern Ireland shipments arrive with the wrong document route and a marking that is not accepted there. |
| Presenting a test report or declaration to a buyer as a CE certificate | A compliance team keeps looking for a document that does not exist for self-declared products, instead of reviewing what you sent. |
| Printing artwork before the importer question is settled | Label reprints, or worse, stock already in the channel naming the wrong party. |
Where we come in
Most of the products we test under the GB regulations sit in the same test scope as their EU file: safety, EMC or radio testing against standards both regimes recognise. One test programme and one report normally supports both submissions, which is exactly what the recognition arrangement was designed to allow.
What we are asked for on the GB side is usually narrower than a full project. Confirming whether a product falls inside the recognised group or into a sector regime, which is set out in our UK and UKCA certification scope. Producing the document set in English, including a Declaration of Conformity naming the right responsible entity. Reviewing label artwork so importer and rating details are correct before anything is printed. And checking whether CE evidence you already hold is still usable for the configuration you are shipping. Our testing and certification scope covers what runs in-house and what goes through partner laboratories, and our project approach explains how a scope review is kept short. The European side of the same file is compared in certifications for selling in Europe.
If the answer is that you do not need UKCA marking, we will say so and stop there. Charging for a second conformity assessment you are not required to hold would be a poor way of earning the next project.
Send us the product, where it is landing - Great Britain, Northern Ireland, or both - and the documents you already hold. We will come back with the mark the goods actually need, whether anything in the existing file has to be redone, and what the label has to carry for whichever party is the importer.
