Why we exist: our role

We were set up by Parliament nearly 50 years ago to help both individuals and the general public. We are not part of government or the NHS: our role is to investigate complaints that individuals have been treated unfairly or have received poor service from government departments and other public organisations in the UK and the NHS in England. Dame Julie Mellor is the current Ombudsman.

Our powers are set out in law and our service is free for everyone but, by law, complaints about Government departments and other public organisations must be referred to us by an MP. This is known as the ‘MP filter’. Complaints about the NHS can come to us directly or through an MP.

We are independent from Government and accountable to Parliament through the Public Administration Select Committee. The law gives us the power to investigate individual complaints and produce a report of our findings which recommends how mistakes can be put right. If our investigations find big or repeated mistakes, we share this information with regulators to help them do their job. We share information about our work with Parliament to help them hold government and the NHS in England to account for the service they provide and the way they handle complaints. Copies of our reports can be found here. You can also find more information about our legislative framework and governance.

As Parliament’s Ombudsman we can help you where you may not be able to resolve a complaint yourself or where a constituent has asked you to refer a complaint to us. We can also assist you in holding public services to account.
