If you are not happy with our response please let us know as soon as possible. Your complaint will be referred to a more senior member of staff, who will carry out a review and let you know the outcome.

If you remain dissatisfied with our response you can contact the Charity Commission or the Office of the Scottish Charity Regulator for advice.

What if I am unhappy with a Macmillan Professional?

Macmillan healthcare professionals are employed and managed by our partners, largely the NHS but also local authorities and other organisations. They carry the Macmillan name as an acknowledgement of their affiliation to us through our initial funding and ongoing support and it is seen as a badge of quality.

All Macmillan professionals are expected to provide the highest possible quality of care and to adhere to the standards set by their own professional body, such as the Nursing and Midwifery Council or General Medical Council. We have agreed quality standards in place with partner organisations and undertake regular reviews of Macmillan services.

If you are unhappy with a Macmillan professional, you will need to complain directly to our partner organisation as their employer, for example the NHS Trust, so that it can be investigated under the correct complaints procedure. We can advise you on how to do this.

Your personal information

If you use our complaints procedure, you are agreeing that we can use any personal information you send us for purposes connected with your complaint. We will only give your personal information to other people and organisations if you have given us permission to do so. If you are able to give this permission when you contact us with details of your complaint, this can help us to start the investigation quickly.
