Our Governance

Marie Stopes UK is a registered charity and reproductive healthcare organisation which is committed to offering the best services for its clients and our NHS commissioners.

Our governance and assurance structures are set up to ensure that we are consistently providing robust, safe and appropriate services for everyone.

The governance of our organisation is rooted within our UK Divisional Board which is a subset of the Marie Stopes International Board who have ultimate responsibility for the organisation. 

Confidence in assurance

Marie Stopes UK’s governance structures and procedures mean we can be confident that the services we are providing are safe and adhere to best practice, the regulatory framework and the law. Our assurance journey covers all aspects of our services.


Policies & Procedures

Our policies and procedures provide the framework within which we work. We have a strict process in which policies are created, reviewed, approved, and ratified. These give our clinical team members guidance on how to deliver abortion services safely and appropriately within best-practice, the regulatory framework and the law.


Training & Competencies

We make sure our UK team members are appropriately trained and competent in all aspects relating to abortion care and our other services in the UK. We have a bespoke training matrix which meets the needs of all team members across the organisation and includes statutory and mandatory training required.


Audit & Checks

To assure the organisation, as well as our regulators, that we are compliant with regulation and the law, we constantly audit our services and supervise our team members. We also put plans into action in areas where we can improve. This allows us to demonstrate that our services are good quality, effective, safe, and that they’re being delivered by the right staff with the right skills and competencies.


Board & Executive Assurance Processes

Effective healthcare organisations have direct flows of assurance from ward to Board. We’ve strengthened our governance structures to make this a two-way process:

  1. Our Leadership Team will have the information they need to provide oversight and scrutiny of everything we do
  2. Our front line teams will understand our strategy and values as a reproductive healthcare charity
