In Great Britain, medical devices are regulated under the Medical Devices Regulations 2002 (UK MDR 2002), enforced by the Medicines and Healthcare products Regulatory Agency (MHRA). Every device has to be registered with the MHRA before it goes on sale, and it needs either a UK Conformity Assessed (UKCA) marking or a valid CE marking. Northern Ireland follows different rules.
The rules moved again this month. On 21 October 2026, the government confirmed it will recognise CE-marked medical devices in Great Britain on a long-term basis, so most brands won't need a separate UKCA route to keep selling here. Registration, labelling and post-market obligations still apply, and a lot of them land on the fulfilment side of your business.
This guide covers what counts as a medical device, which rules apply where, how UKCA and CE marking work today, what you need before you sell, and where device compliance tends to go wrong once stock moves into a Third-Party Logistics (3PL) warehouse.
What counts as a medical device?
A medical device is a product used for a medical purpose, such as diagnosing, preventing, monitoring or treating a condition, that works mainly by physical means rather than through a drug. The MHRA's guidance uses "medical device" to include in vitro diagnostic devices (IVDs), such as home tests, and active implantable devices.
More ecommerce products fall into this category than many brands expect. Plasters, bandages, walking aids, hearing aids, condoms, pregnancy tests and home blood glucose meters are all regulated as medical devices. The intended purpose is what counts, so the claims on your product page and packaging can decide whether a product is a medical device at all.
In Great Britain, devices are grouped into classes by risk. The class decides whether you can self-certify or need an independent assessment:
Class | Risk | Examples | Who assesses conformity |
Class I | Low | Plasters, non-sterile bandages, walking aids | The manufacturer self-certifies |
Class I sterile or measuring | Low, with added risk | Sterile dressings, devices with a measuring function | A UK approved body (UKCA) or EU notified body (CE) |
Class IIa | Medium | Hearing aids, daily-wear contact lenses | An approved body or notified body |
Class IIb | Medium to high | Condoms, long-term contact lenses | An approved body or notified body |
Class III | High | Heart valves, breast implants | An approved body or notified body |
IVDs | Varies | Pregnancy tests, home blood glucose meters | Depends on the IVD category, with self-test IVDs needing independent assessment |
If you're unsure where a product sits, check with a regulatory adviser before you list it. Classification errors are expensive to fix once stock is in the market.
Which medical device regulations apply in the UK?
The UK has two sets of rules for medical devices, depending on where the product is sold.
Great Britain (England, Scotland and Wales): devices are regulated under the UK MDR 2002. These regulations were originally based on the old EU directives for medical devices, active implantable devices and IVDs. The newer EU Medical Devices Regulation (EU MDR) and In Vitro Diagnostic Regulation (EU IVDR) took effect after the Brexit transition period ended, so they don't apply in Great Britain.
Northern Ireland: under the Windsor Framework, the EU MDR has applied since 26 May 2021 and the EU IVDR since 26 May 2022. Devices sold there need a CE marking, and the UKCA marking isn't recognised.
The MHRA regulates both markets. It carries out market surveillance and can take decisions on how devices are marketed and supplied across the UK.
For brands, the practical point is simple: stock that's compliant for Great Britain isn't automatically compliant for Northern Ireland. If you ship to both, check the marking on every product line. The same applies if you also sell into the EU, where only CE marking is accepted.
UKCA marking and CE marking for medical devices
The UKCA marking is the UK's own product marking for devices sold in Great Britain. It shows the device meets the UK MDR 2002. Where independent assessment is needed, it's carried out by a UK approved body. The UKCA marking isn't recognised in the EU or Northern Ireland.
In practice, most devices on sale in Great Britain carry a CE marking. More than 90% of devices registered here carry one, according to the government. The UK MDR 2002 treats a CE-marked device with a valid certificate as meeting UKCA requirements for as long as CE marking is recognised. Devices can also carry both markings.
Current CE marking deadlines
Under the law as it stands, CE-marked devices can be placed on the Great Britain market until these dates:
Device type | Can be placed on the GB market until |
General medical devices under the EU Medical Devices Directive (MDD) or Active Implantable Medical Devices Directive (AIMDD) | 30 June 2028, or certificate expiry if sooner |
IVDs under the EU In Vitro Diagnostic Directive (IVDD) | 30 June 2030, or certificate expiry if sooner |
General medical devices under the EU MDR, and IVDs under the EU IVDR | 30 June 2030 |
What changed in October 2026
On 21 October 2026, the government confirmed it will recognise CE-marked medical devices and IVDs in Great Britain indefinitely, following a consultation that closed in April. Devices certified under the EU MDR and EU IVDR will keep access to the Great Britain market without an extra UK assessment. For older MDD devices, the government intends to align with the EU's own transition period, which currently runs to 31 December 2028.
The legal changes are expected before 30 June 2028, subject to parliamentary approval. Until then, the deadlines in the table above still apply. The UKCA route stays open as an option, and the MHRA has said further reforms are on the way, including new rules on Unique Device Identification (UDI).
For brands, this removes the biggest planning headache of the last five years. It doesn't remove registration, labelling or post-market obligations, which still apply in full.
What you need before selling medical devices in Great Britain
Whichever marking your devices carry, four requirements apply before and after they go on sale in Great Britain.
MHRA registration: every medical device, including IVDs, custom-made devices and system or procedure packs, must be registered with the MHRA before it's placed on the Great Britain market. The MHRA only accepts registrations from UK-based manufacturers, and a fee is payable for new registrations and changes. The MHRA is clear that an unregistered device can't lawfully be placed on the market.
A UK Responsible Person (UKRP): if the manufacturer is based outside the UK, it must appoint a single UKRP for all its devices. The UKRP registers the devices, keeps the technical documentation and declaration of conformity available for the MHRA, cooperates on corrective action and passes complaints about suspected incidents back to the manufacturer. Importers and distributors don't need to appoint one, but they can act as the UKRP themselves.
Labelling: devices need a UKCA or CE marking, plus the approved body or notified body number where relevant. If the device carries a UKCA marking, including when it's dual-marked, the UKRP's name and address must appear on the label, the outer packaging or the instructions for use. CE-only devices don't need UKRP details on the label.
Post-market surveillance: manufacturers must monitor how their devices perform once they're on the market, report serious incidents to the MHRA and take safety action when needed. Stricter rules came into force on 16 June 2025 for devices placed on the Great Britain market from that date, covering surveillance plans, trend reporting and more detailed incident reports.
If you import devices from a non-UK manufacturer and you're not the UKRP, you must tell the manufacturer or its UKRP that you intend to import them, and they then give the MHRA your details. Importers and distributors also have obligations around storage, transport and checking that device labels carry the right marking. That's where your fulfilment setup comes in.
Where medical device compliance goes wrong in fulfilment
Device compliance is usually in good shape when stock leaves the manufacturer. The risks build up after that, during storage, packing and returns. The regulatory responsibility stays with the manufacturer, the UKRP or you as importer or distributor, even when a 3PL handles the physical work.
Storage conditions: many devices carry storage instructions for temperature, humidity or light. Some IVD test kits and reagents need chilled storage. If the label sets a storage range, your warehouse has to hold it, and it should be able to prove it with temperature records. Our guide to cold chain logistics covers what to look for.
Batch, serial and expiry tracking: when a manufacturer issues a Field Safety Notice or recall, you need to know which customers received which batch, quickly. That depends on your Warehouse Management System (WMS) capturing lot or serial numbers at goods-in and dispatch, and picking on a First Expired, First Out (FEFO) basis. Plenty of general ecommerce warehouses don't do this as standard.
Wrong marking for the destination: UKCA-only stock can't go to customers in Northern Ireland or the EU. If you hold both versions, they need separate Stock Keeping Units (SKUs) so a picker can't send the wrong one.
Damaged sterile packaging: a torn pouch or crushed box can make a sterile device unusable. Goods-in checks and careful handling need to catch damage before it reaches a customer.
Kitting and relabelling: putting devices together into a kit can create a system or procedure pack, which needs its own MHRA registration. Relabelling or repackaging can also change who's responsible for the device. Check with your regulatory adviser before your 3PL changes any device packaging.
Complaints that go nowhere: a customer emailing to say a device failed may be reporting a suspected incident. If that message reaches your 3PL or customer service team, it has to get to the manufacturer or UKRP fast, because post-market surveillance depends on it.
Returns: a returned device with an opened seal, damaged packaging or unclear batch code shouldn't go back into sellable stock. A 3PL that restocks returns by default needs a separate rule for your device lines, including a quarantine area.
Questions to ask a medical device 3PL
A warehouse that's great with apparel or homeware can still be the wrong fit for medical devices. These questions help you find providers that already work to the right standards. Use them alongside our questions for a 3PL discovery call.
Experience: which medical device brands do you already work with? Similar device classes and storage needs are a good sign. Ask for a reference you can call.
Quality management: do you hold ISO 13485, the quality management standard for medical devices? If not, ask how you'd manage document control, training and audits for device stock.
Traceability: can your WMS capture batch, lot or serial numbers at goods-in and dispatch, and pick on a FEFO basis?
Storage conditions: can you hold the temperature and humidity ranges on my labels, and can you share monitoring records?
Goods-in checks: do you check labels, markings and packaging condition on arrival, and what happens to damaged or non-compliant stock?
Quarantine: can you quarantine a batch on request the same day, and keep it physically separate from sellable stock?
Recalls: how quickly can you identify and pull every order containing a specific batch? Ask when they last did it for real.
Complaints: how will product complaints that reach your team get passed to us, and how fast?
Returns: what's your process for returned devices, and who decides whether anything goes back into stock?
Market separation: can you keep Great Britain, Northern Ireland and EU stock under separate SKUs and stop the wrong version going to the wrong address?

Medical device regulations FAQs
Is UKCA marking mandatory for medical devices?
No. CE-marked devices can be sold in Great Britain under the current transitional arrangements, and the government confirmed in October 2026 that it will recognise CE-marked devices indefinitely. UKCA marking remains available as an alternative route.
Can I sell CE-marked medical devices in the UK after 2030?
The government intends to allow it for devices certified under the EU MDR and EU IVDR, with the legal changes expected before 30 June 2028. Until those changes are made, the current deadlines of 30 June 2028 and 30 June 2030 still apply.
Do I need a UK Responsible Person?
Yes, if the manufacturer is based outside the UK and you want to sell its devices in Great Britain. The manufacturer appoints one UKRP for all its devices.
Does the UK Responsible Person need to be on the label?
Only for UKCA-marked devices, including devices carrying both UKCA and CE markings. CE-only devices don't need UKRP details on the label.
Do all medical devices need to be registered with the MHRA?
Yes. Every device, including IVDs, custom-made devices and system or procedure packs, must be registered before it's placed on the Great Britain market.
What rules apply in Northern Ireland?
Northern Ireland follows the EU MDR and EU IVDR. Devices need a CE marking, and the UKCA marking isn't recognised there.
Who's responsible if my 3PL ships a non-compliant device?
Regulatory responsibility sits with the manufacturer, the UKRP and any importer or distributor in the chain, which usually means your brand. That's why traceability, storage controls and clear packing instructions matter when you outsource fulfilment.
