If you have made a formal complaint about an NHS service which could not be resolved locally, you can contact the Parliamentary and Health Service Ombudsman (PHSO) to request an independent investigation into your complaint.

They will only do this if the organisation you have complained about have confirmed in writing that they cannot do any more to resolve your concerns. This is called a final decision letter’, and you can remind the organisation you are complaining about to send it to you.

Visit the PHSO website, or call them, to find out if they are able to support the kind of issue you need help with.

When you contact the Ombudsman they will ask you to complete an online or paper form to make your complaint. Fill this in as fully as you can. You’ll need to enclose the final decision letter from the organisation you’re complaining about.

The Ombudsman is independent of the NHS and of Government, and their powers are set down in law. Their service is confidential and free. The final decision of the Ombudsman is the last stage of the NHS complaints procedure, but you do have a right to appeal that decision. To make an appeal, contact the Ombudsman directly.

What happens when the Ombudsman carries out an investigation

Every complaint is different, which means that every investigation will be different. The Ombudsman will speak to the organisation(s) concerned and look at all the facts.

This could mean asking the organisation to:

  • give a clearer explanation of their actions
  • acknowledge their mistakes and provide an apology to you
  • take steps to make sure mistakes do not happen again

2. The Ombudsman decides that the NHS have already resolved the issue

They will explain their decision, sharing any expert advice they have received.

If you think the Ombudsman’s decision is wrong

The Ombudsman’s decision about your complaint is usually final, but sometimes they can review their decision to make sure that it was fair, and based on all the available evidence. If the Ombudsman reviews their decision and you are still not happy, you have the right to request an appeal through the courts using judicial review. 

To do this you would need to provide evidence that one or more of the following have happened:

  • the Ombudsman have made their decision based on incorrect information
  • the Ombudsman have misunderstood the information
  • new information has come to light since the decision has been made
