Exceptional Use Authorisation: In this guidance MHRA outlines how manufacturers can apply for exceptional use authorisation (EUA) which allows non-UKCA/CE certified medical devices to be placed on the UK market when doing so in the interest of the protection of public health. EUAs are granted for a limited time, with conditions to facilitate compliance with relevant medical devices legislation. Once granted, manufacturers must report monthly to the MHRA on supply figures, complaints, adverse events, and progress towards UKCA or CE certification (for EUAs granted for the Great Britain market); or CE certification (for EUAs granted for the Northern Ireland or whole UK market).

Association for Approved Bodies: Team-AB is the trade association for UK Approved Bodies.
Manufacturers can access the GB market either through UKCA certification or via recognition of CE certification until July 2028 for general medical devices, or July 2030 for IVDs, depending on the applicable EU legislation.
The UK government is pursuing proposals for comprehensive reform of devices regulation under UKCA. In the meantime, the current Medical Devices Regulations 2002 continue to apply. Devices in NI remain subject to different arrangements under the Windsor Framework, with ongoing alignment to EU rules.
In light of the government’s July 2025 response to its consultation on medical device regulation, and the planned introduction of a new UK medical device regime in 2026, CE-marked devices may continue to be placed on the GB market during the transitional period. The government has also announced plans to consult later in 2025 on indefinite recognition of CE-marked devices.
Additionally, the government intends to remove the mandatory requirement for UKCA marking on devices and associated labelling that have undergone UK conformity assessment. This change will be conditional on the assignment of a Unique Device Identifier (UDI), which must be searchable in a publicly accessible database expected to be operational in 2026.
Transitional Arrangements notwithstanding, manufacturers are able to obtain UKCA Certification currently. As outlined in Sections 2-5 above, obtaining a UKCA mark is materially similar to obtaining a CE mark – the main difference being that the Declaration of Conformity (for self-certified Class I devices or general IVDs) or Assessment Certificate (for 3rd-party assessed Class I Special Function, Class II-and-above device, self-test IVD, IVD included in Annex II list B, or IVD included in Annex II list A) is issued by a UK Approved Body (UK AB) rather than an EU Notified Body (EU NB) against UK MDR 2002 (as amended).
For more information on UKCA marking, please see:
The Role of the UK Responsible Person (UKRP): See this guidance for the roles and responsibilities of a UKRP, which could form the basis of a contract between a manufacturer and a UKRP; in summary, a UKRP must:

European Association of Authorised Representatives (EAAR): The EAAR is an alliance of providers of EU Authorised Representative (EUAR) services. When placing devices on the EU or Northern Ireland markets, manufacturers from GB or other countries outside the EU must appoint either an EU-based or NI-based authorised representative[5]. If you wish to find a professional EUAR, the email addresses of members can be found on the EAAR Members page.
[5] NB, there are some companies that provide both UKRP and EUAR services; in instances where these companies have a registered office in Northern Ireland, it is possible that a UKRP and EU authorised representative could be the same entity.

MHRA – Guidance on Class I Medical Devices: Although derivative of the full guidance in Sections 7-8 above, this advice on Class I medical devices – eligible for self-certification in most cases because of their low risk profile – is a useful guide; e.g. MHRA lists areas that must be covered by a manufacturer’s Technical File; in summary these are:
MHRA is the UK regulator for medical devices. It performs market surveillance of medical devices on the UK market and is able to take a decision regarding the marketing and supplying of a device in the UK. MHRA are also responsible for the designation and monitoring of UK conformity assessment bodies. For medical devices, these approved bodies are organisations that have been designated by MHRA to assess whether manufacturers and their medical devices meet the requirements set out in relevant UK medical device regulations.
MHRA – Regulating Medical Devices in the UK
This guidance sets out what is required to place a medical device on the GB, NI, and EU markets, and what MHRA does within each of these processes. This is the best overview from which to understand the medical device regulatory landscape, with sub-sections on:
MHRA – Post market Surveillance
In addition to the above guidance, MHRA has published a collection of guidance which covers post marketing surveillance information for manufacturers placing products on the GB market. This collection provides guidance on the measures that came into force on 16 June 2025, related to the SI laid in 2024 – The Medical Devices (Post-market Surveillance Requirements) (Amendment) (Great Britain) Regulations 2024. While these provisions are similar in intent to EU PMS requirements, there are important differences in scope and implementation. Manufacturers therefore need to ensure that their systems and documentation meet the specific UK requirements in addition to EU obligations, as compliance with one framework does not automatically demonstrate compliance with the other. The collection includes:
The main changes introduced by the amended PMS legislation include:
MHRA – Register Medical Devices to Place on the Market
Before a device can be placed on the market in the UK it must be registered with the MHRA. This guidance sets out how to register medical devices with MHRA for devices intended for the GB and NI markets. This is the best overview from which to understand the medical device registration journey with MHRA, with links to different parts of the process, including:

All medical devices, including IVDs, custom-made devices and systems or procedure packs, must be registered with MHRA before they can be placed on the GB market. A registration fee is required, more information on registration fees can be found in Section 2.
It is possible under UK and EU legislation [4] to combine medical devices together into a procedure pack. In the retail sector, this is most commonly seen in first aid kits, but it is not limited to this application. It is atypical to see the kit/pack as a whole CE/UKCA marked (indeed it is prohibited to do so except in some limited and rare circumstances), but any individual medical device product contained in the kit/pack should be CE/UKCA marked. It is therefore necessary to verify each individual component within a kit/pack for compliance. The CE/UKCA mark only applies to medical devices, and kits/packs may contain non-medical device products.
A full list of registration information – Organisation Details (mandatory); Importer Details (if applicable); General Device Details (mandatory); IVD Details (if applicable) – is available from MHRA as an Excel spreadsheet at Manufacturer and Device and Product and Importer Attributes.
For each manufacturer, required details include:
For each device, required details include:
Further guidance is provided for the registration of reusable or unclassified (those devices whose classification will change to a higher risk classification on implementation of the EU MDR) and/or devices relying on expiring CE certificates can be found here:
* ‘up-classified’ refers to a situation where a device that was placed in a lower risk class under the Medical Devices Directive (MDD 93/42/EEC) is now placed in a higher risk class under the Medical Devices Regulation (MDR (EU) 2017/745)) as a result of stricter MDR classification rules.
A Manufacturer or UKRP must create an account on MHRA DORS before beginning to register medical devices with MHRA.
MHRA will email account applicants to confirm whether any account request has been accepted or rejected.
NB: You will not be regarded as registered with MHRA until you have provided detailed information required at registration. Before placing devices on the market, you must ensure all information registered with MHRA is accurate and up to date; MHRA may request additional technical documentation from you to demonstrate your products conform to the relevant regulatory requirements before your registration is confirmed.
To set up an account:
A statutory fee of £261 applies for each registration application.
Registrants can register up to 100 devices (GMDN) with a cumulative maximum of 20,000 products (UDI-DI, medical device name, model or version, catalogue/reference detail) within each application.
If registrants need to update any information within an existing registration, a statutory fee is applicable.
Following the MHRA consultation on statutory fees – proposals on ongoing cost recovery, and extensive stakeholder feedback, the government has revised its approach to medical device fees.
The previously proposed £210-per-GMDN annual fee will be replaced with a new £300 annual fee, applicable per GMDN Level 2 category (or Level 1 where Level 2 does not exist). This new fee structure will replace the current one-off £261 registration fee and will come into effect on 1 April 2026, instead of April 2025 as originally planned. The change aims to support post-market surveillance (PMS) activities. Approximately 60% of manufacturers are expected to pay only a single charge. All fees will continue to be paid via DORS. More information can be found within the government response to the consultation.
Until the new fee structure comes into effect on 1 April 2026, the statutory fee of £261 applies for each registration application applies.
MHRA encourages regular review of device registrations and sets out here their program of review notification within the DORS system.
MHRA sets out here which changes to device registration – including address, company name, additional devices, change of UKRP – are chargeable.

To determine if a product is a medical device and, if so, into which class it fits (as per Section 2), the following sources of information can be used.
MHRA Guidance:
This provides a comprehensive overview of how MHRA makes decision on whether a product is a medical device and which risk class should apply. It also includes information on how to get advice about your product from the MHRA and provides links to other borderline guidance.
MHRA guidance to assist in determining whether a product falls within the definition of a medical device for the purposes of UK legislation/regulation. See especially, Section 5 – Assistive technology products (aids for daily living):
Equipment intended for alleviation of, or compensation for a disability may or may not be considered medical devices. The determining factor will be whether or not there is a direct link between the corrective function of the equipment and the individual concerned and whether there is a stated medical purpose. The following products are considered to be medical devices as there is such a direct link:
Other products, however, will be considered as ‘general equipment’ since it may be used ‘by all’ (rather than having a direct link with the individual concerned). Such products are usually considered as ‘aids for daily living’ and are not medical devices, for example:

MHRA further defines what it considers a medical device in the context of assistive technologies. In addition to the examples in the borderlines guidance above, see especially its definitions of:

[3] UK law – Medical Devices Regulations 2002 (SI 2002 No. 618, as amended (UK MDR 2002)) – defines “medical device” as:
An instrument, apparatus, appliance, material or other article, whether used alone or in combination, together with any software necessary for its proper application, which—
(a) is intended by the manufacturer to be used for human beings for the purpose of-
(i) diagnosis, prevention, monitoring, treatment or alleviation of disease,
(ii) diagnosis, monitoring, treatment, alleviation of or compensation for an injury or handicap,
(iii) investigation, replacement or modification of the anatomy or of a physiological process, or
(iv) control of conception; and
(b) does not achieve its principal intended action in or on the human body by pharmacological, immunological or metabolic means, even if it is assisted in its function by such means,and includes devices intended to administer a medicinal product or which incorporate as an integral part a substance which, if used separately, would be a medicinal product and which is liable to act upon the body with action ancillary to that of the device.
The MHRA Regulating Medical Devices in the UK guidance sets out MHRA’s requirements (see Section 7) as augmented by April 2023 MHRA Implementation Guidance, press statements, and Statutory Instrument (including Explanatory Notes), It can be summarised as follows:
A Transition Date Matrix showing transition dates based on device class and legislation under which a device is currently registered is available on the next page. See also the June 2023 MHRA Infographic of the timelines for placement of CE-marked medical devices on the GB market.

MHRA has published a roadmap to the implementation of the medical device future regime which includes a forward-looking roadmap and other resources:
Post-Brexit, the UK has allowed CE-marked medical devices to remain on the UK market. In GB, this is for a transitional period (see below and Section 4), and under the Windsor Framework Agreement , CE marking will be required for medical devices being sold in NI. Under European requirements (EU MDR 2017/745), medical devices are required to demonstrate compliance by display of a CE mark to be sold legally in the EU (and for as long as the CE mark continues to be accepted in the UK). See MHRA: Medical devices: EU regulations for MDR and IVDR (Northern Ireland) for CE requirements to place products on the NI market, including importer and registration obligations.
Qualifying NI goods may continue to be placed on the market in GB on the basis of a valid CE marking on an indefinite basis. This arrangement is as a result of the government’s commitments to Northern Ireland’s unfettered access to the market in the rest of the UK, and is underpinned by the UK Internal Market Act 2020.
On 21 May 2024, MHRA published a statement of policy intent for international recognition of medical devices, which provides for new, future routes to placing a medical device on the GB market via a certificate of International Reliance (IR). This draft policy indicates that a framework will be established to allow for reliance on assessments performed by comparable regulator countries (CRCs), resulting in a certificate of international recognition, which will allow the medical device to be placed legally on the GB market. The table below indicates the CRCs which are to be included in the envisioned IR framework.
| Country or Jurisdiction | Regulatory Authority |
|---|---|
| Australia | Therapeutic Goods Administration (TGA) |
| Canada | Health Canada |
| European Union (EU) | National competent authorities in the member states of the EU/ European Economic Area (EEA) |
| United States of America (USA) | Food and Drug Administration (FDA) |
MHRA intend to proceed with implementing the proposed international reliance routes. The proposed framework would provide an IR certificate that will grant devices access to the GB market, but it will not provide a UK Conformity Assessed (UKCA) marking, or UKCA certification. If, for the purposes of placing a device on the GB market, an IR certificate was issued based on an EU CE certification, the device could also be placed on the NI market. Given the feedback to the consultation, there will be further consultation on the indefinite acceptance of CE marking. The finalised IR framework and accompanying operational guidance are expected in 2026. IR routes will not open until the new UK medical device regime comes into force, also in 2026. In the meantime, for more detail, please see the MHRA Consultation on Medical Devices Regulations: Routes to market and in vitro diagnostic devices, and the Government response to international reliance, UKCA marking and in vitro diagnostic devices consultation proposals.
UKCA Marking
Where a medical device is placed on the GB market, by demonstrating compliance with the UK MDR 2002 (as amended), a UKCA mark should be displayed. UKCA marking is not currently mandatory for medical devices placed on the GB market, but will become so on expiry of the transitional periods, introduced by MHRA’s Spring 2023 Statutory Instrument (SI) (see Section 4 for full detail). Under the new UK regulatory regime, planned to be introduced in 2026, regulatory requirements in GB will be similar to those introduced by EU MDR/EU IVDR. Medical devices in GB, after a transition period, will be required to demonstrate compliance against these updated regulations either by undergoing a UKCA assessment procedure or through the international reliance procedure.
As outlined in the MHRA Consultation on Medical Devices Regulations: Routes to market and in vitro diagnostic devices, devices that have undergone the UK conformity assessment process may no longer be required to carry a UKCA mark or associated labelling to be placed on the GB market once the 2026 regulation update comes into force.
UKNI Marking
Under the terms of the Windsor Framework Agreement, from 1 January 2021 the rules for placing medical devices on the NI market will differ from those applicable to GB. As a result, the EU MDR and EU IVDR applied in NI from 26 May 2021 and 26 May 2022, respectively, in line with the EU’s implementation timeline. To apply a CE mark, high-risk medical devices and IVDs require review from an EU Notified Body. However, where a UK assessment body has provided an assessment in line with EU MDR or EU IVDR, a UK Northern Ireland (UKNI) mark can be applied for the purpose of placing the device on the NI market. MHRA guidance states:
“UK Notified Bodies can apply to be designated under the relevant EU legislation for the purposes of conducting conformity assessments for the Northern Ireland market. Please note that there are currently no UK Notified Bodies designated to undertake such assessments under the EU MDR or the EU IVDR. This section outlines the criteria for affixing a UKNI marking to devices should any UK Notified Bodies be designated in future. In addition to the CE marking, device manufacturers will also need to apply the UKNI indication if they choose to use a UK Notified Body (should any be designated in future) for mandatory third-party conformity assessment. Device manufacturers must never apply the UKNI indication on its own – it must always accompany a CE marking.”
Transitional arrangements (see Section 4) mean the CE mark will continue to be accepted to place medical devices on the UK market for the immediate future (until as late as June 2030 in some cases).

Medical devices fall into the following five groups across three classes:
IVDs vary hugely from medical devices (despite being a sub-category of medical device) and therefore, these products have a different classification structure.
Under the UK MDR 2002 (as amended), IVDs fall into the following four groups across three classes:
Class I devices and general IVDs are “self-certified”; a manufacturer is responsible for assembling and maintaining technical files and other compliance documents in line with the regulations and then makes a Declaration of Conformity (DoC) per product. The DoC is lodged with the relevant national regulatory authority (MHRA in the UK), which may ask to examine technical files. A DoC lasts for as long a product remains “substantially unchanged” in design, purpose, or application. As of 2022/23, the costs for placing a class I device or general IVD on the UK market (exclusive of companies’ own regulatory/compliance staff overheads) can be estimated as follows:
Class I special function (measuring, sterile or reusable), all class II and above devices, self-test IVDs, IVDs included in Annex II list B, and IVDs included in Annex II list A are “3rd party assessed”; a manufacturer must obtain and maintain a CE or UKCA certificate through an EU Notified Body (NB) designated by an EU Member State or UK Approved Body (AB) designated by MHRA. EU NBs and UK ABs are independent companies appointed under law by a relevant national authority which provide 3rd party technical and compliance assessment. Provided a product remains “substantially unchanged” in design, purpose, or application, a certificate lasts for a set period of time (e.g. 3-5 years), after which 3rd party re-certification must take place to verify continued conformity.
As of 2025/26, the costs for placing a class I special function, class II-and-above device, self-test IVD, IVD included in Annex II list B, or IVD included in Annex II list A on the UK market (exclusive of companies’ own regulatory or compliance staff overheads) might be estimated as follows:
On 02 September 25, MHRA published an update to the Government Response to the MHRA Consultation on Statutory Fees for medical devices.
The response outlines the final proposals for the introduction of a new annual fee to support post-market surveillance (PMS) activities for medical devices. This follows extensive consultation with stakeholders across the sector the including responding to the challenges raised to the initial government fee proposals. The revised approach reflects feedback from industry, including trade associations, and trusted advisor groups, and aims to ensure a fairer distribution of costs while safeguarding patient safety and supporting innovation.
The new fee structure will come into effect from 1 April 26, with further guidance and support to be published in the coming months to help the medical devices community to prepare. Important updates are:
Medical devices are regulated under the Medical Devices Regulations 2002 (SI 2002 No. 618, or UK MDR)[1]. This secondary legislation translated into UK law the 1990 EU Active Implantable Medical Devices Directive (EU AIMDD), 1993 EU Medical Device Directive (EU MDD), and 1998 EU In Vitro Diagnostic medical device Directive (EU IVDD). Following Brexit, UK MDR has gone through a series of amendments.
EU MDD and EU AIMDD were superseded by the 2017 EU Medical Device Regulation 2017/745, or EU MDR, while EU IVDD was superseded by the 2017 EU In Vitro Diagnostic medical device Regulation 2017/746, or EU IVDR. Because EU MDR and EU IVDR post-dated the Brexit transition period, it was not automatically retained in the UK, by the EU (Withdrawal) Act 2018.
However, the EU MDR and EU IVDR are still relevant to the UK. Market access for UK medical devices is governed by its application for both access to Northern Ireland (NI) and where the Conformité Européene (CE) mark is applied. Since 26 May 2021, the EU MDR has applied in the EU and NI as a consequence of the Windsor Framework Agreement (previously known as the Northern Ireland Protocol), while EU IVDR has applied in the EU and NI since 26 May 2022. The EU MDR and EU IVR also apply in Great Britain (GB) where a CE marked device is placed on the market (see Section 2).
[1] Pre-Brexit, this gives/gave effect in UK law to: Directive 90/385/EEC on active implantable medical devices (EU AIMDD); Directive 93/42/EEC on medical devices (EU MDD); Directive 98/79/EC on in vitro diagnostic medical devices (EU IVDD).
