A UK MHRA Certificate of Free Sale (CFS) for patient warming devices supports overseas documentation for registered medical thermal-management equipment. Its schedule connects selected warming systems to the manufacturer’s specifications, component descriptions and conformity documentation.
The issued certificate can then be prepared for overseas use through verification, professional certification, an apostille and any required embassy legalisation.
Product category and MHRA registration: Patient Warming Devices
External patient warming devices are general medical devices intended to provide controlled warming for the medical thermal-management applications specified by their manufacturer. Designs may use warmed air with compatible blankets or controlled conductive warming surfaces. The intended purpose defines the patient population, clinical setting, intended users and the particular warming arrangement supported by each model.
The MHRA’s Device Online Registration System, or DORS, holds manufacturer, device and product records. Registration includes the relevant conformity information, such as CE or UKCA documentation, together with the details identifying the products. For manufacturers based outside the UK, a UK Responsible Person represents the manufacturer for the Great Britain registration process.
The MHRA’s medical device registration guidance explains the registration framework. The April 2026 reference guide describes how these records are entered and maintained in the online system.
For Great Britain, the manufacturer’s records sit within the UK medical device framework. A CFS order is submitted by an eligible UK-based manufacturer or UK Responsible Person, using registered products and the relevant CE or UKCA conformity evidence.
Documents and product information
The registration process brings together information about the manufacturer, the product and its conformity documentation. The main records include:
- Manufacturer details: the legal manufacturer’s name, registered address and contact information.
- UK Responsible Person documentation: representative details and the designation agreement, where applicable.
- Product details: warming-unit name, model, catalogue reference, legal manufacturer, heat-delivery method, temperature-control arrangement and compatible patient interfaces. Labels, instructions, conformity documents and technical-file records describe thermal performance, controls, applicable alarms, electrical safety and cleaning. Component documentation identifies supplied hoses, blankets, pads or mattresses, with material and single-use or reusable characteristics where relevant.
- Registration identifiers: the GMDN code and term, with Basic UDI-DI and UDI-DI where applicable.
- Conformity documentation: the Declaration of Conformity and applicable conformity assessment certificates, including their references, validity and product schedules.
- Supporting product records: labels, instructions for use and the technical and performance documentation held by the manufacturer.
The online registration links the relevant conformity documents to the device record and identifies the individual products beneath it. The wider technical documentation supports the manufacturer’s compliance records; it is not a separate standard upload package for each CFS order.
From MHRA registration to an electronic CFS
- Accepted registration establishes the manufacturer, device and individual product records in DORS. Current conformity documents are linked to the relevant entries.
- The applicant selects the products marked CFS Ready and reviews the certificate and schedule preview. Model names and catalogue references come from the registered product data.
- After the order is submitted and paid for, the MHRA issues an electronically signed PDF. The complete certificate and every schedule page form the document set for subsequent verification and legalisation.
The MHRA CFS Reference Guide describes these stages. The published CFS service information gives an issuance aim of ten working days, with longer processing possible during busy periods.
Product coverage in the CFS schedule
One warming platform may support several blanket shapes, pad sizes or connection arrangements for different documented applications. The registered descriptions identify the supplied system presentations and the entries selected for the CFS. Separately marketed blankets, replacement hoses and warming surfaces can retain distinct catalogue references and applicable product records. Equipment that warms blood or infusion fluids has a different product purpose from a system warming the patient externally. The full schedule and compatibility documentation distinguish the included warming products from the manufacturer’s wider thermal-management range.
Direct verification of the CFS with the MHRA
For an overseas submission, the authenticity of the issued certificate is an important part of document preparation. Ginkgo Advisory can arrange for a solicitor to seek direct confirmation of the CFS with the MHRA and review the certificate together with its schedule.
Solicitor certification and express UK FCDO apostille
Where the solicitor-certified route is accepted for the intended submission, Ginkgo Advisory can arrange solicitor certification followed by a UK FCDO paper apostille. The certification format is matched to the receiving authority’s requirements. MHRA’s published guidance describes a notarial route, and notarisation is arranged where that route is required.
Our express UK FCDO apostille service normally takes two working days once verification and the required certification are complete and the document is accepted for submission. The apostille stage has its own timetable, separate from MHRA certificate issuance, verification responses, any embassy processing and delivery. Further FCDO checks can affect completion.
Embassy legalisation for Egypt, the UAE, Kuwait and Qatar
Ginkgo Advisory can arrange embassy legalisation where required, bringing the verification, certification, apostille and relevant embassy submission into one coordinated service. The destination and intended use determine the required document format and any additional stages.
Preparing an issued MHRA CFS for overseas use
For a quotation, the starting documents are the MHRA-issued electronic PDF and all accompanying schedule pages. The issuance email, destination country, receiving authority’s instructions and required completion date help establish the appropriate preparation and delivery arrangements.

Product questions
Does a warming-unit certificate cover every compatible blanket size?
The manufacturer’s records identify the blanket variants supported by the unit and how they are supplied. Certificate coverage follows the selected registered product descriptions and issued schedule. Compatibility alone does not show that every separately marketed blanket reference is included in the same CFS; the component and product entries establish the actual scope.
