Free NHS Complaint Letter Template That Gets Results (2026 UK Guide)

Had a bad experience with the NHS? You have the right to complain. This guide shows you how.

Your Rights as an NHS Patient

The NHS Constitution gives you clear rights. You have the right to:

• Be treated with dignity and respect
• Receive safe, high-quality care
• Be given clear information about your treatment
• Complain and get a response

These aren't just guidelines. They're legal rights.

When Should You Complain?

Complain if you experienced:

• A misdiagnosis or delayed diagnosis
• A cancelled or missed appointment
• Rude or dismissive treatment
• A medication error
• Poor aftercare

Don't stay silent. Your complaint could help others too.

Who to Complain To

You have two options:

Option 1: Complain to the NHS trust directly. This is the fastest route. Most trusts have a Patient Advice and Liaison Service (PALS).

Option 2: Complain to NHS England. Use this if the trust doesn't resolve your complaint.

You have 12 months from the incident to complain. Act quickly.

What to Include in Your Letter

Keep your letter clear and factual. Include:

1. Your full name and NHS number
2. The date and location of the incident
3. What happened — in plain language
4. How it affected you
5. What you want — an apology, an explanation, or a review

Attach any relevant documents. Keep copies of everything.

After You Send the Letter

The NHS must acknowledge your complaint within 3 working days. They must respond fully within 25 working days.

If you're not happy with their response, you can contact the Parliamentary and Health Service Ombudsman (PHSO). This is free. They investigate NHS complaints independently.
