If you need to complain about the way a Coroner or his or her staff handled an investigation (for example if you feel the standards are not being met) you should first write to the Coroner, and copy your letter to the local authority which funds the service. The Coroner's office will be able to advise you of the relevant local authority, if you are unsure of this.
You may also complain direct to the local authority. If you are still dissatisfied after its response you may complain to the Local Government Ombudsman or by calling 0300 061 0614 or 0845 602 1983. Alternatively you may complain in writing to:
The Local Government Ombudsman

There is no charge to complain about the standard of service from a Coroner's office.
