The NHS ignored your formal complaint. Here is what comes next.

You complained to a trust or GP practice and got silence, or a reply that dodged the point. Give it the dates and what went wrong, and it writes a formal referral to the Parliamentary and Health Service Ombudsman: the timeline, the failure, and what you want resolved. The next step when the NHS has stopped listening.

Write a formal referral letter to the Parliamentary and Health Service Ombudsman (PHSO) regarding an unresolved NHS complaint. Background: I submitted a written complaint to [trust or GP practice name] on [date] about [brief description of the clinical or service failure]. Their response: [describe what happened: no response / inadequate response / response that did not address key points]. The letter should: confirm I have exhausted the trust's complaints process, reference the original complaint and any reference number [ref], state the specific failures I want investigated, and request PHSO to take the case forward. Tone: measured and precise.
