Complaining about NHS care feels uncomfortable. It feels like you're attacking the people trying to help you. But NHS complaints aren't about blame — they're about accountability. And done properly, they're one of the most effective tools patients have for getting problems resolved.

When to complain

A complaint is appropriate when: you've experienced a significant delay that breached NHS constitutional targets; you've received care that fell below an acceptable standard; communication has broken down and informal attempts to resolve it have failed; or you believe a clinical error has occurred.

A complaint is not necessary for minor issues that can be resolved informally — through PALS, through your GP, or through direct conversation with the clinical team.

The formal complaint process

Step 1: Write, don't call. A written complaint creates a record and triggers a formal response obligation. Address it to the complaints department of the relevant NHS trust. Be specific: dates, names, what happened, and what outcome you want.

Step 2: State the outcome you want. Do you want an explanation? An apology? A change in your care plan? A review of clinical practice? Being clear about your desired outcome focuses the response.

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

Step 4: If unsatisfied. If the trust's response doesn't resolve your complaint, you can escalate to the Parliamentary and Health Service Ombudsman. This is free, independent, and has the power to require trusts to take action.

Practical tips

Keep emotion out of the written complaint — state 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 that you need an immediate response on the care pathway while the complaint is investigated.
