UKCA (UK Conformity Assessed) marking is the mandatory product conformity mark for medical devices sold in Great Britain (England, Wales, and Scotland) following Brexit. It replaces CE marking and is governed by the UK MDR 2002 under MHRA oversight. CE-marked devices can still enter the GB market under transitional rules until June 2028 or 2030 (depending on device type), but all manufacturers must register with the MHRA and — if outside the UK — appoint a UK Responsible Person. Getting a head start on UKCA compliance now protects your market access long-term.
Why UKCA Marking Matters Right Now
If you manufacture or export medical devices to the UK, there is one compliance question you cannot afford to ignore in 2026: UKCA marking for medical devices.
Since Brexit, Great Britain (England, Wales, and Scotland) has built its own regulatory framework for medical devices. The result is a new conformity mark — the UKCA mark — that is slowly replacing the EU’s CE mark on the UK market. But the transition has been anything but simple. Deadlines have shifted multiple times, MHRA guidance has evolved, and many manufacturers are still unsure where they stand.
This guide cuts through the confusion. Whether you are a UK-based manufacturer, a global company exporting to Britain, or a regulatory consultant advising clients, you will find accurate, current, and practical information here. And if you need expert support navigating these regulations, traccglobal.com offers end-to-end UKCA compliance services designed specifically for medical device companies.
⚠ IMPORTANT – 2026 Update
In July 2025, the MHRA confirmed that new post-market surveillance rules came into force on 16 June 2025, and further regulatory changes are expected to apply from mid-2026, including amendments to device classification and transparency requirements. Do not rely on guidance older than mid-2025.
What Is UKCA Marking for Medical Devices?
UKCA stands for United Kingdom Conformity Assessed. It is a product marking introduced by the UK government on 1 January 2021, the day the Brexit transition period ended. For medical devices, the UKCA mark signals that a product meets the safety and performance requirements set out in the UK Medical Devices Regulations 2002 (UK MDR 2002).
Think of it as the UK’s own version of the CE mark. Before Brexit, medical device companies needed CE marking to access European markets, including the UK. After Brexit, Great Britain created its own route: the UKCA mark.
What Does the UKCA Mark Look Like?
The UKCA mark uses the letters “UKCA” in a specific font and size. When a UK Approved Body is involved in the conformity assessment, you must also display that body’s unique identification number alongside the mark. The mark must be visible, legible, and permanently affixed to the device or its packaging.
Note: as of the MHRA’s July 2025 update, the physical UKCA logo requirement may eventually be replaced by a Unique Device Identifier (UDI) system — but this change is not yet in force and depends on the UDI database becoming operational.
Where Does UKCA Apply?
The UKCA mark applies in Great Britain only — that is England, Wales, and Scotland. It does not apply in:
- Northern Ireland — which follows EU regulations under the Windsor Framework and requires CE (or CE+UKNI) marking.
- The European Union — CE marking is still required; UKCA is not recognised.
- Any other international market — each country has its own conformity requirements.
ℹ KEY POINT
If you sell in both Great Britain and Northern Ireland, you need two separate compliance strategies. UKCA alone does not cover Northern Ireland. You may need dual marking — UKCA for GB and CE (with or without UKNI) for Northern Ireland.
Why UKCA Mark Requirements Matter — Even With Transitional CE Acceptance
A common question we hear at TraccGlobal is: “If CE marking is still accepted in Great Britain, do I really need to worry about UKCA right now?”
The short answer is: yes, you do. Here is why.
- MHRA registration is already mandatory — regardless of whether your device carries CE or UKCA marking, all devices must be registered with the MHRA before being placed on the GB market. This is not optional.
- CE transitional acceptance has conditions — your device must be unchanged and your EU Notified Body certificate must still be valid. Any significant modification may trigger the need for UKCA certification.
- New devices need UKCA now — if you are launching a new product or your CE certificate has expired, you need the UKCA route.
- The 2028/2030 deadlines are approaching — planning and certification take time. Waiting until the last minute risks supply disruptions.
- Regulatory divergence is real — the UK is developing its own regulatory updates that may diverge from EU MDR. UKCA compliance future-proofs your GB market access.
- UK Responsible Person requirement — non-UK manufacturers must already appoint a UKRP to register devices. This is a live obligation, not a future one.
CE Marking vs UKCA Marking: Key Differences
The CE to UKCA transition is one of the most important regulatory shifts for medical device companies since the EU MDR came into force. Here is a clear comparison to help you understand the key differences.
| FEATURE | CE MARKING | UKCA MARKING |
|---|---|---|
| Governing Body | European Commission / National Competent Authorities | MHRA (UK) |
| Legal Framework | EU MDR 2017/745 / EU IVDR 2017/746 | UK MDR 2002 (as amended) |
| Conformity Assessment | EU Notified Body | UK Approved Body |
| Market Access | EU, Iceland, Norway, Liechtenstein, Northern Ireland | Great Britain (England, Wales, Scotland) |
| Registration | EUDAMED (EU database) | MHRA Device Registration (DORS) |
| Representative | EU Authorised Representative (for non-EU companies) | UK Responsible Person (for non-UK companies) |
| Technical Documentation | Based on EU MDR/IVDR | Based on UK MDR 2002 (aligned with MDD/AIMDD/IVDD) |
| Mutual Recognition | Not recognised in GB for UKCA purposes | Not recognised in EU |
| Self-Certification | Class I non-sterile, non-measuring devices | Class I non-sterile, non-measuring devices + general IVDs |
| Post-Market Surveillance | EU MDR PMS requirements | UK-specific PMS (updated June 2025) |
Can You Dual-Mark a Device?
Yes. Many manufacturers choose to dual-mark their devices with both CE and UKCA marks. This is currently permitted and is often the most commercially sensible strategy for companies selling to both the UK and EU markets. Dual marking reduces regulatory risk and ensures market access on both sides, regardless of how transitional rules evolve.
The Regulatory Framework: UK MDR 2002 and MHRA
UK Medical Devices Regulations 2002 (UK MDR 2002)
The legal foundation for UKCA mark requirements is the Medical Devices Regulations 2002 (SI 2002 No 618, as amended) — commonly referred to as the UK MDR 2002. This was originally the UK’s implementation of the old EU Medical Device Directives (MDD, AIMDD, and IVDD). After Brexit, it became the UK’s standalone framework.
Key aspects of UK MDR 2002 cover:
- Device classification rules (Class I, IIa, IIb, III for general devices; Classes A–D for IVDs)
- Conformity assessment routes and requirements
- Essential requirements for safety and performance
- MHRA registration obligations
- Labelling and instructions for use requirements
- Post-market surveillance and vigilance reporting
⚠ UPCOMING CHANGES
The MHRA is developing a new, updated regulatory framework expected to take effect from mid-2026 onwards. This new regulation will introduce amendments to device scope, classification, UDI requirements, and international reliance routes (allowing manufacturers to leverage FDA, Health Canada, EU, and Australian regulatory approvals for faster UK access). Keep monitoring MHRA communications closely.
The MHRA’s Role in UK Medical Device Regulation
The Medicines and Healthcare products Regulatory Agency (MHRA) is the UK’s competent authority for medical devices. It is responsible for:
- Designating and overseeing UK Approved Bodies (the equivalent of EU Notified Bodies)
- Managing the Device Online Registration System (DORS) — mandatory for all devices entering the GB market
- Enforcing post-market surveillance and vigilance reporting requirements
- Investigating non-compliance and withdrawing unsafe products from the market
- Consulting with industry and publishing updated guidance
As of April 2026, there are nine designated UK Approved Bodies for medical devices, including major names like BSI, TÜV SÜD, and SGS. You can find the full list on the UK’s UKMCAB database.
Device Classification Under UK MDR 2002
Understanding your device’s risk classification is the first critical step. UK MDR 2002 uses a risk-based classification system for general medical devices:
- Class I — lowest risk (e.g., bandages, crutches). Non-sterile, non-measuring Class I devices can self-certify.
- Class IIa — low-to-medium risk (e.g., hearing aids, short-term contact lenses)
- Class IIb — medium-to-high risk (e.g., ventilators, X-ray equipment)
- Class III — highest risk (e.g., coronary stents, implantable pacemakers)
For IVDs (in vitro diagnostic devices), a separate classification system applies: general IVDs (can self-certify), List A (highest risk, e.g., HIV test kits), and List B (e.g., pregnancy tests).
How to Obtain UKCA Marking: Step-by-Step Process
Here is the practical roadmap for achieving UKCA marking for medical devices. The specific steps vary slightly depending on your device’s classification, but the overall process follows this structure.
Step 1- Classify Your Medical Device
Use the classification rules in UK MDR 2002 (Schedule 1, Part II for general devices or Part IV for IVDs) to determine your device’s risk class. Your classification determines your conformity assessment route, documentation requirements, and whether you need a UK Approved Body. If you are unsure, get expert classification advice — getting this wrong is a costly mistake.
Step 2- Appoint a UK Responsible Person (if non-UK based)
If your organisation is not based in the UK, you must appoint a UK Responsible Person (UKRP) before placing any device on the GB market. The UKRP must be based in Great Britain and serves as the primary MHRA contact. They are legally responsible for ensuring conformity procedures are followed, serious incidents are reported, and technical documentation is available. TraccGlobal provides UKRP services for international manufacturers entering the UK market.
Step 3- Choose Your Conformity Assessment Route
Your route depends on device classification:
- Class I (non-sterile, non-measuring) and general IVDs: Self-certification. You assess conformity yourself, prepare a Declaration of Conformity, and affix the UKCA mark.
- Class I sterile (Is) or measuring (Im), Class IIa, IIb, III and higher-risk IVDs: Mandatory third-party assessment by a UK Approved Body.
Step 4- Prepare Your Technical Documentation
You must compile comprehensive technical documentation demonstrating that your device meets all essential requirements. This includes device description and intended purpose, design and manufacturing information, risk analysis and risk management (ISO 14971), clinical evaluation, pre-clinical testing data, labelling and IFU, and quality management system documentation (typically ISO 13485). For Class III devices, a Design Dossier is required. Technical documentation must be retained for 10 years from the last date of manufacture.
Step 5- Engage a UK Approved Body (if required)
For devices that require third-party assessment, select a UK Approved Body from the UKMCAB database. The UK Approved Body will audit your QMS (typically against ISO 13485), review your technical documentation or Design Dossier, and if satisfied, issue a UKCA Certificate of Conformity. Be aware that capacity at UK Approved Bodies can be limited — early engagement is strongly recommended to avoid delays.
Step 6- Issue a UK Declaration of Conformity
Once conformity has been assessed (either self-certified or via an Approved Body), you must issue a formal UK Declaration of Conformity (DoC). This document declares that your device meets all applicable UK MDR 2002 requirements. It must include the manufacturer’s name and address, device description and classification, applicable UK legislation, and the Approved Body’s name and certificate number (if applicable).
Step 7- Register with the MHRA
Before placing your device on the GB market, you must register it with the MHRA through the Device Online Registration System (DORS). This applies to all devices — whether UKCA or CE marked under transitional rules. The registration fee is £240 per application. You will need to provide technical documentation, your Declaration of Conformity, and your Approved Body certificate details. The UKRP completes registration on behalf of non-UK manufacturers.
Step 8- Affix the UKCA Mark and Place on Market
Once registered and certified, you can affix the UKCA mark to your device, packaging, or accompanying documentation. The mark must be visible, legible, and indelible. If an Approved Body was involved, their identification number must appear next to the mark. For non-UK manufacturers, the UKRP’s name and GB address must also be included on the label or outer packaging.
Step 9- Maintain Post-Market Surveillance Obligations
Compliance does not end at certification. Since 16 June 2025, updated post-market surveillance requirements apply. These include implementing PMS Plans, PMS Reports, and Periodic Safety Update Reports (PSURs). You must also report serious incidents and field safety corrective actions (FSCAs) to the MHRA within shortened timeframes. Vigilance obligations are ongoing for the device’s entire market lifetime.
Documentation Required for UKCA Mark Requirements
Proper documentation is the backbone of your UKCA compliance. The level of detail required scales with your device’s risk classification, but every manufacturer must have the following documents ready.
Device description and specifications (including intended purpose and patient population)
Risk management file (aligned with ISO 14971)
Clinical evaluation report (clinical data, literature review, post-market clinical follow-up plan)
Pre-clinical test reports (biocompatibility, electrical safety, sterility, etc.)
Quality Management System documentation (ISO 13485 certification strongly recommended)
Design and manufacturing information (materials, components, supply chain)
Labelling and Instructions for Use (IFU) in English
UK Declaration of Conformity
Approved Body certificate number (if applicable)
Post-market surveillance plan and reports
Summary of Safety and Performance (for Class III and implantable devices)
ℹ GOOD NEWS FOR CE-CERTIFIED MANUFACTURERS
If your device already has MDD/IVDD-compliant technical documentation, it generally meets the current UKCA marking requirements with some gaps to address — primarily replacing references to EU legislation with UK legislation, updating your EU Authorised Representative to a UK Responsible Person, and adding MHRA registration. This makes the transition considerably faster for many companies.
UKCA Compliance Timeline: Key Deadlines
Understanding the CE to UKCA transition timeline is critical for planning. Here are the key dates as of April 2026.
1 JAN 2021
UKCA marking introduced. CE marking still accepted in GB under transitional rules.
16 JUNE 2025
New UK post-market surveillance requirements enter into force for all GB-market devices.
30 JUNE 2028
CE marking (MDD/AIMDD) transitional period ends for most device classes. UKCA or International Reliance required after this.
30 JUNE 2030
CE marking (IVDD) transitional period ends for in vitro diagnostic devices. UKCA required after this.
MID-2026+
New UK medical device regulation expected to apply. Changes to classification, UDI, and international reliance routes anticipated.
TBD
Physical UKCA logo may be replaced by UDI requirement once national UDI database is operational.
⚠ IMPORTANT CONDITION
CE transitional acceptance in GB only applies if your device is unchanged and your EU Notified Body certificate remains valid. Any significant modification — design change, new intended use, manufacturing change — may require UKCA certification immediately, regardless of the transitional deadline.
Common Challenges and How to Overcome Them
Achieving UKCA marking for medical devices is not without obstacles. Here are the most common challenges manufacturers face — and practical ways to address them.
1. Limited UK Approved Body Capacity
There are currently only nine UK Approved Bodies designated under UK MDR 2002. Capacity is limited, and wait times for initial applications can stretch to several months. Solution: Engage early — do not wait until you are close to your CE certificate expiry or a transitional deadline. Submit your application as soon as your technical documentation is ready.
2. Navigating the CE-to-UKCA Documentation Gap
Many manufacturers assume their existing MDD/IVDD documentation can be transferred wholesale. There are gaps to address — updated legislation references, a new UK DoC format, and UK-specific PMS requirements. Solution: Commission a gap analysis against UK MDR 2002 requirements before beginning your UKCA application.
3. UK Responsible Person Obligations
Non-UK manufacturers often underestimate the ongoing obligations of their UKRP. This is not a passive role — the UKRP has active legal duties around incident reporting, documentation availability, and MHRA communication. Solution: Choose a UKRP partner with genuine regulatory expertise, not just a postal address. TraccGlobal provides active, expert UKRP services that fulfil the full scope of MHRA obligations.
4. Northern Ireland Complexity
Companies selling to both GB and Northern Ireland must manage two entirely separate compliance frameworks — UKCA for GB and CE (under EU MDR/IVDR) for Northern Ireland. Solution: Map your market geography clearly and build a compliance strategy that addresses both. Dual marking is the most resilient approach.
5. Keeping Up with Evolving MHRA Guidance
MHRA guidance has changed multiple times since 2021 and will continue to evolve, particularly as the new UK regulatory framework takes shape from mid-2026. Solution: Sign up for MHRA update notifications and work with a regulatory partner who monitors changes proactively.
Expert Tips for Successful UKCA Compliance
Based on experience supporting medical device companies through UK market access, here are the strategic insights that make the biggest difference.
- Start with MHRA registration now — even if you are relying on transitional CE acceptance, MHRA registration is already a live legal obligation. Get this done immediately if you have not already.
- Do not treat UKCA as just a paperwork exercise — the MHRA is actively developing post-market surveillance enforcement capabilities. Compliance needs to be genuine, not just documentary.
- Plan for the International Reliance route — the MHRA’s upcoming framework will allow manufacturers to leverage FDA clearance, EU CE, Health Canada, or TGA (Australia) approvals for faster GB market access. If you already have these approvals, start tracking MHRA updates on International Reliance carefully.
- Invest in ISO 13485 certification — a certified QMS is not strictly mandatory for self-certifying Class I devices, but UK Approved Bodies will expect it for all higher-risk devices. It also significantly streamlines your Approved Body audit.
- Build dual CE + UKCA capability simultaneously — if you are renewing your EU certificate, use the same audit cycle for UKCA. The cost and time savings are significant.
- Document your post-market surveillance proactively — the June 2025 PMS changes introduced shorter incident reporting timelines and mandatory PSUR requirements. Implement proper PMS systems now, before an incident occurs.
Frequently Asked Questions
What is UKCA marking for medical devices?
UKCA (UK Conformity Assessed) marking is the mandatory product conformity mark for medical devices placed on the market in Great Britain (England, Wales, and Scotland) following Brexit. It was introduced on 1 January 2021 and is governed by the UK Medical Devices Regulations 2002 (UK MDR 2002) under the oversight of the MHRA (Medicines and Healthcare products Regulatory Agency). The UKCA mark demonstrates that a device meets UK safety, performance, and quality requirements. It replaces the CE mark for the GB market but is not recognised in Northern Ireland or the EU.
Is CE marking still accepted for medical devices in the UK in 2026?
Yes — CE marking is still accepted in Great Britain under transitional arrangements. Devices certified under the old EU Medical Device Directive (MDD/AIMDD) can remain on the GB market until 30 June 2028 (or when the certificate expires, whichever is sooner). IVDs certified under the old IVDD directive have a transitional period until 30 June 2030. However, these transitional arrangements have conditions: the device must be unchanged and the EU Notified Body certificate must remain valid. All manufacturers — even those relying on transitional CE acceptance — must register their devices with the MHRA.
What is the difference between UKCA and CE marking for medical devices?
The key differences are: CE marking is governed by European Commission regulations (EU MDR/IVDR) and gives market access across all EU countries plus Iceland, Norway, and Liechtenstein. UKCA marking is governed by UK law (UK MDR 2002) and gives market access only in Great Britain. CE conformity assessments are done by EU Notified Bodies; UKCA assessments are done by UK Approved Bodies. Non-EU manufacturers need an EU Authorised Representative for CE marking; non-UK manufacturers need a UK Responsible Person for UKCA. Crucially, neither mark is recognised in the other’s jurisdiction — UKCA does not work in the EU, and CE (on its own) will not work in GB once transitional periods end.
Do I need a UK Responsible Person for UKCA marking?
Yes — if your organisation is based outside the UK, you must appoint a UK Responsible Person (UKRP) before placing any medical device on the GB market. This is a legal requirement under UK MDR 2002 and applies whether your device carries UKCA or CE marking under transitional rules. The UKRP must be located in Great Britain (not Northern Ireland). They are responsible for MHRA registration, maintaining technical documentation, and managing vigilance and incident reporting. Note that their name and UK address must appear on device labelling when UKCA marking is affixed.
How long does it take to get UKCA certification for a medical device?
The timeline varies significantly by device class. For Class I devices with self-certification, the process can be completed in weeks — once technical documentation is ready, you issue a Declaration of Conformity and register with the MHRA. For higher-risk devices requiring a UK Approved Body, the process typically takes 6–18 months from initial application to certificate issuance. This includes document review, QMS audit, and any requested clarifications. Key bottleneck: UK Approved Body capacity is limited, so early engagement is critical. If you have existing MDD-compliant documentation, the UKCA process may be faster, as it can often be adapted rather than rebuilt from scratch.
What does UKCA marking cost for medical devices?
Costs depend on device class and whether a UK Approved Body is required. MHRA device registration costs £240 per application. For Class I self-certification, the main costs are internal resource time for documentation preparation and possibly consultant fees. For Class IIa–III devices requiring a UK Approved Body, you will pay fees for QMS audits, technical file review, and certificate issuance — these typically range from several thousand to tens of thousands of pounds depending on device complexity and the Approved Body’s rate structure. Companies that leverage existing MDD/IVDD documentation and combine CE and UKCA Approved Body audits can achieve significant cost savings.
Does UKCA marking apply in Northern Ireland?
No. UKCA marking does not apply in Northern Ireland. Under the Windsor Framework, Northern Ireland remains aligned with EU medical device regulations (EU MDR and EU IVDR). Medical devices placed on the Northern Ireland market must carry CE marking (or CE + UKNI when a UK Notified Body has been involved in the conformity assessment). Manufacturers selling across the whole of the UK — both Great Britain and Northern Ireland — must therefore maintain compliance with both UKCA (for GB) and CE/UKNI (for Northern Ireland).
What are UK Approved Bodies and how do I choose one?
UK Approved Bodies are organisations designated by the MHRA to carry out mandatory third-party conformity assessments for medical devices under UK MDR 2002. They are the UK equivalent of EU Notified Bodies. As of 2026, there are nine designated UK Approved Bodies, including BSI, TÜV SÜD, SGS, and Eurofins. You can find the full, up-to-date list on the UK government’s UKMCAB database. When choosing, consider: device types they are designated for, current application wait times, whether they also offer CE marking services (useful for dual marking), and their track record with similar devices. Some UK Approved Bodies are accredited for all device types; others have limitations.
