Guide to Complaint Processes

Clear routes for complaints, reviews, appeals, ombudsmen, regulators, data requests and public-service escalation — with the right process separated from the wrong one.

Complaints Should Not Be Harder Than the Original Problem

Good records, clear written communication and using the correct route can make a major difference. A service complaint and an appeal against a decision are often different processes, so using the wrong route can waste time or risk a deadline.

THE USUAL COMPLAINT JOURNEY

Know Where You Are in the Process

Different organisations use different names, but most complaint routes follow a recognisable sequence.

1

Raise the issue

Contact the service or department responsible and explain what went wrong.

2

Formal complaint

Use the written complaint route and get a reference number.

3

Internal review

Ask for escalation or a senior review where the process allows it.

4

Appeal or tribunal

If the issue is the decision itself, use the correct statutory challenge route.

5

External oversight

Use the relevant ombudsman, regulator or specialist examiner when available.

BEFORE YOU COMPLAIN

Make the Problem Easy to Understand

A complaint is stronger when the investigator can quickly see the history, evidence, failure and outcome you want.

Gather evidence

  • letters and emails
  • decision notices
  • reference numbers
  • call dates and notes
  • payment or account records
  • photographs or screenshots
  • relevant policies and guidance

State the outcome you want

  • correction of records
  • written explanation
  • fresh decision or review
  • apology
  • refund or compensation where appropriate
  • safeguarding action
  • service improvement

COMPLAINT OR APPEAL?

Use the Route That Matches the Problem

A complaint usually concerns service failure, delay, conduct, lost evidence or failure to follow process. An appeal or statutory review challenges the decision itself.

A complaint may not protect an appeal deadline

For benefits and some Child Maintenance decisions, GOV.UK says you can ask for a Mandatory Reconsideration when you disagree with the decision. You normally need to do this within one month of the decision, although the exact route depends on the decision notice.

  • identify the decision being challenged;
  • explain what you think is wrong and why;
  • send relevant evidence;
  • keep proof of submission;
  • check the deadline shown on the decision notice.

Use “Formal Complaint” where that is what you are making.
Include the correct case or account reference.
List important events in date order.
Separate facts from opinion.
Identify policies or guidance where genuinely relevant.
Explain the personal, practical or financial impact.
List the evidence attached.
State the remedy or outcome requested.
Ask for a complaint reference.
Ask when a response is due.
Keep copies of every submission.
Record calls, dates and names.

A complaint can be much easier to evidence when you have the relevant records, case notes, correspondence or decision information.

DATA PROTECTION — LAW CHANGE

New Data-Protection Complaint Duty from 23 June 2026

The ICO says new legal requirements now apply to organisations handling personal data.

Clear complaint route

Organisations must provide a clear way for people to raise a data-protection complaint.

30-day acknowledgement

A data-protection complaint must be acknowledged within 30 days, investigated appropriately and the outcome communicated.

Different from subject access

A complaint about how information was handled is different from asking for a copy of your personal information, although the issues can overlap.

Official ICO guidance

Check the ICO's explanation of the new duty.
