Complaining about the NHS feels uncomfortable. It feels like you're attacking people trying to help you. But NHS complaints aren't about blame — they're about accountability. And they're one of your most powerful tools for getting problems fixed.

When should you complain?

A complaint makes sense when: there's been a significant delay that breaks NHS constitutional promises; you've received care that fell below acceptable standards; communication has broken down and informal attempts haven't helped; or you believe a clinical error happened.

A complaint isn't needed for small issues that can be resolved informally — through PALS (the Patient Advice and Liaison Service), through your GP, or through direct conversation with the clinical team.

The formal complaints process

Step 1: Write it down, don't just call. A written complaint creates an official record and requires a formal response. Send it to the complaints department of the NHS trust involved. Be specific: include dates, names, exactly what happened, and what outcome you want.

Step 2: State what you want to happen. Do you want an explanation? An apology? A change to your care plan? A review of how the team handles this situation? Being clear about your goal focuses the response and speeds resolution.

Step 3: Understand the timeline. NHS trusts must acknowledge your complaint within 3 working days and send a full response within a timeframe agreed with you (usually 25–65 working days depending on complexity).

Step 4: If you're still not satisfied. If the trust's response doesn't resolve things, you can escalate to the Parliamentary and Health Service Ombudsman. It's free, independent, and has power to require trusts to take action.

Practical tips for better results

Keep emotion out of the written complaint — stick to facts, not feelings. Reference specific standards or guidelines that weren't met. Keep copies of everything. If the issue is ongoing and affecting your current care, make clear you need an immediate response on the care side while they investigate the complaint.
