    MHRA / UKCA Marking

    UK regulator and post-Brexit conformity marking for medical devices in Great Britain.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

    Definition

    The Medicines and Healthcare products Regulatory Agency (MHRA) regulates devices in Great Britain under the UK MDR 2002 (as amended). UKCA marking will replace CE marking for the GB market on a transition timeline currently extended through 2030 for many device classes.
    What the regulation says
    The MHRA is the UK competent authority responsible for regulating medical devices in Great Britain, operating under the Medical Devices Regulations 2002 (as amended). The UKCA mark indicates conformity with these UK regulations. For medical devices, the transition period for mandatory UKCA marking has been extended, with specific deadlines depending on device class, as outlined in MHRA guidance.

    What this means in practice

    Northern Ireland continues to follow EU rules under the Windsor Framework, requiring CE/UKNI marks. UK Approved Bodies - separate from EU Notified Bodies - perform conformity assessments for UKCA.

    Examples

    • A manufacturer of Class IIa surgical instruments currently holding a CE mark must ensure their devices will achieve UKCA marking by the extended deadline to continue being sold in England, Wales, and Scotland.
    • A company based in the United States intending to market a novel implantable device in Great Britain must appoint a UK Responsible Person and obtain UKCA marking through a UK Approved Body.
    • A quality manager is reviewing their company's regulatory strategy to ensure that all Class III devices have a valid UKCA certificate well in advance of the 2028 mandatory compliance date.
    Common pitfalls
    • •Failing to understand the extended transition timelines for UKCA marking can lead to non-compliance for devices placed on the Great Britain market.
    • •Confusing the requirements for UKCA marking with CE marking, which applies in the EU and Northern Ireland, can result in incorrect conformity assessments.
    • •Not engaging with a UK Approved Body for higher-risk devices requiring third-party conformity assessment under UKCA regulations is a common pitfall.
    • •Assuming that a device with a CE mark can automatically be placed on the Great Britain market without considering any additional UKCA specific requirements, even during the transition period.
    • •Overlooking the specific requirements for economic operators, such as UK Responsible Persons, when marketing devices in Great Britain under UKCA regulations.
