Information for professionals

The Matrix Project is committed to working in partnership with other organisations. We are very happy to joint work clients - supporting other agencies where we can. If you have a client that fits our criteria and would appreciate our input, please contact us.

The Matrix has an information sharing agreement which can be used with agencies to allow helpful exchange of information. We also ask consent from our clients to share their information if appropriate.

We love working with other organisations. If you have ideas for ways we can do this which we are not already doing - please let us know.

We also love sharing about The Matrix; what we do and how we do it. If you are interested in finding out more, please call 01603 883423 or email us

Research and academic collaboration

We welcome enquiries from academic institutions interested in developing research with us. The Matrix is a member of UKNSWP which has Good Practice Guidance freely available for further information.

Sex workers are an over-researched group and any research inquiry must support our work and add to a body of knowledge that improves services for our clients.

Before approaching us you should have a clear outline of your research intentions including:

  • The aims of the study
  • The researcher’s theoretical position
  • The proposed research design and methods
  • The ethical considerations to be taken into account and how these will be adhered to, including informed consent and confidentiality, and how the welfare of participants will be assured during the research
  • How users will be involved in the research
  • The use to which the research will be put, including how the findings from the research will be fed back to participants.

We also ask you to provide a current CV, which includes examples of previous work you have undertaken.

Research proposals should adhere to ethical practice and should have Research Ethics Committee approval from the university you are based in.  You will also need approval from the NHS Ethics Committee(s) before commencing the research.  If you are independent or not based in a university you still require NHS Research Ethics Committee approval.

It is your responsibility to obtain this.

Guidance on ethics procedures for health organisations can also be found in the Department of Health Research Governance Framework for Health and Social Care

 The Matrix Project statement of purpose

The Matrix Project offers as responsive, accessible service to those working in the sex industry and those engaging in risky sexual behaviour. The team will co-work with clients and other agencies and through education increase awareness of the needs of this client group.

The service will apply a multi-disciplinary method of working utilising the principles of harm reduction to encourage sex workers and those engaging in risky sexual behaviour to make their own risk assessments and informed choices about their lifestyles.

Additionally the Matrix Project will provide access to many services in an outreach capacity, including health, and encourage clients to uptake care pathways as set out in the Models of Care. The aim is to improve quality of life amongst both the client group and those affected by their lifestyle choices.

‘While an individual might have highly complex and serious needs in a wide range of domains; suggesting the need for high intensity and complex treatment, a low level of motivation might initially require a low threshold of intervention. In this situation, the emphasis would be on engagement, and motivating the client with the aim of stabilisation to allow for further assessment and help in accessing more structured and/or intensive treatment’.
