How ICE Fits Into the CMS Complaints System
These additions use current GOV.UK, DWP, ICE and Parliamentary Ombudsman guidance.
You Need the Final Complaint Response First
ICE's current guidance says do not contact ICE until you have received a final response from the business or agency you complained to which says you can take the complaint to ICE.
If you contact ICE before that final response, ICE says it will not investigate the complaint.
How to bring a complaint to ICEICE Deadline: Within 6 Months
Current ICE and DWP guidance says you must normally contact ICE within 6 months of receiving the final complaint response.
Keep the final response letter or message because ICE may ask to see it.
ICE deadline and eligibilityICE Is a Free, Impartial Review Service
GOV.UK describes ICE as an impartial referee for people who feel they have been treated unfairly or are unhappy with how their complaint has been handled. The service is free.
Official ICE overviewICE Covers CMS and DWP Complaints
ICE's published remit includes complaints from customers of DWP, including the Child Maintenance Service, Child Support Agency, Jobcentre Plus, Pension Service and other DWP services.
Independent Case ExaminerMaladministration Is Different From an Appeal
DWP's complaints procedure says it does not investigate complaints about government policy or law. If you want to challenge a child maintenance assessment or other appealable decision, you need to use Mandatory Reconsideration and, where available, tribunal appeal.
ICE focuses on complaint handling, maladministration and service delivery rather than replacing the statutory appeal process.
DWP complaints procedure CMS decision challengesWhat Redress May Be Considered
DWP's current complaint guidance says that where unfair treatment is established it may consider an apology, explanation, corrective action or a special payment where financial loss was suffered.
ICE annual reports also show cases where ICE has recommended additional redress following identified maladministration. Any payment depends on the facts and is not automatic.

DWP's Subject Access Request process can provide your CMS account information, case records and evidence used in a dispute or investigation. This can be useful when reconstructing timelines, missing evidence or payment histories.
DWP Subject Access RequestAfter ICE: Parliamentary Ombudsman
DWP says that if you remain unhappy after ICE's final response, you can ask an MP to refer the complaint to the Parliamentary and Health Service Ombudsman (PHSO).
DWP's current procedure says this should normally be done within 12 months of receiving ICE's final response.
PHSO government complaints Find your MPPHSO Normally Requires an MP Referral
PHSO states that, by law, complaints about UK government departments and other UK public organisations normally need to be referred by a Member of Parliament.
This is sometimes called the “MP filter”.
PHSO referral rulesYou Can Use a Representative
ICE guidance permits a representative to act on your behalf. If you need someone else to deal with DWP or ICE for you, make sure the appropriate authority or consent is in place.
ICE complaint guidanceBuild a Strong ICE Complaint Pack
Keep the complaint focused on service failure and maladministration rather than simply repeating the underlying disagreement.
Important: Do Not Let the ICE Process Replace an Appeal Deadline
If the underlying issue is an appealable CMS decision, an ICE complaint does not automatically protect or extend Mandatory Reconsideration or tribunal deadlines. The complaint route and statutory decision-challenge route may need to run separately.
Important Clarification About “False Arrears”
ICE may investigate how CMS handled evidence, payment records, complaints or administrative errors connected with alleged arrears. But ICE is not a tribunal deciding the legal merits of every arrears calculation. If the disputed balance comes from an appealable maintenance decision, the MR/tribunal route may also be required.
Official ICE, CMS & Accountability Sources
Independent Case Examiner (ICE)
The detailed guide below preserves all of the content supplied for this page.
What Is the Independent Case Examiner (ICE)?
Independent Review of Child Maintenance Service (CMS) Complaints, Maladministration, Service Failures, Accountability & Your Rights
The Independent Case Examiner (ICE) is an independent complaints body that investigates certain complaints about government organisations, including the Child Maintenance Service (CMS) and the Department for Work and Pensions (DWP).
ICE exists to provide an independent review where a person believes that CMS or DWP has failed to provide an acceptable standard of service and where the organisation's own complaints process has not resolved the issue.
For many Paying Parents, ICE can be an important safeguard where concerns exist regarding:
- False arrears
- Missing payments
- Evidence allegedly ignored
- Poor complaint handling
- Administrative errors
Delays
- Lost documents
- Poor communication
- Failure to follow procedures
- Unreasonable service failures
ICE is not part of CMS and does not work for the Child Maintenance Service.
Its purpose is to provide an independent investigation into complaints about how a case has been handled.
What Is ICE?
The Independent Case Examiner is an independent office that investigates complaints about:
- Child Maintenance Service (CMS)
- Department for Work and Pensions (DWP)
- Certain government benefit and support services
ICE reviews complaints about service delivery and maladministration.
What Does ICE Do?
ICE investigates whether:
- Procedures were followed correctly.
- Service standards were met.
- Evidence was handled appropriately.
- Communication was reasonable.
- Records were maintained properly.
- Delays occurred unnecessarily.
- Complaint handling was fair.
- Administrative errors occurred.
What Is ICE's Role?
ICE acts as an independent reviewer where someone remains dissatisfied after completing the CMS complaints process.
Its role is to determine whether the service provided was reasonable and whether any failures occurred.
ICE focuses on:
Service Quality
How CMS handled the case.
Administrative Fairness
Whether procedures were followed properly.
Complaint Handling
Whether complaints were investigated appropriately.
Accountability
Whether mistakes should be acknowledged and corrected.
What ICE Does Not Normally Do
One of the most important things to understand is that ICE is not a tribunal and is not a court.
ICE does not normally decide:
- Whether child maintenance should be paid.
- Who should win a dispute.
- Child contact arrangements.
- Family Court matters.
- Appealable maintenance calculations.
Those matters are usually dealt with through:
- Mandatory Reconsiderations
- Independent Tribunals
- Courts
What Can ICE Investigate?
Examples include:
Delays
Excessive delays in:
- Reviews
- Complaints
- Decision making
- Responses
Lost Documents
Evidence allegedly submitted but not properly recorded.
Ignored Evidence
Concerns that evidence was not properly considered or logged.
Poor Communication
Examples may include:
- Unclear explanations
- Failure to respond
- Repeated misinformation
Incorrect Record Keeping
Concerns regarding:
- Missing records
- Incorrect case notes
- Inaccurate information
Complaint Handling Failures
Where CMS complaints procedures have not been followed correctly.
Administrative Errors
Mistakes that affect service delivery.
Common Complaints Raised By Paying Parents
Many Paying Parents approach ICE where they believe:
- Payments were not properly credited.
- False arrears have been created.
- Evidence has repeatedly been ignored.
- Shared care information has not been recorded correctly.
- CMS failed to respond to concerns.
- Complaints were not investigated properly.
- Important documents went missing.
ICE may examine how CMS handled these concerns.
When Can You Contact ICE?
Generally, you must first complete the CMS complaints process.
ICE will normally expect that:
Step 1
You have complained directly to CMS.
Step 2
CMS has had the opportunity to investigate.
Step 3
You remain dissatisfied with the outcome.
Only then will ICE usually consider investigating the complaint.
How Does The ICE Process Work?
Stage 1 – Complaint Received
ICE reviews the complaint.
Stage 2 – Assessment
ICE decides whether it can investigate.
Stage 3 – Investigation
Relevant records may be reviewed.
This can include:
- Complaint files
- Case notes
- Correspondence
- Internal records
Stage 4 – Findings
ICE issues findings explaining:
- What happened
- Whether service failures occurred
- Whether improvements are recommended
Stage 5 – Recommendations
ICE may recommend actions to resolve the complaint.
What Powers Does ICE Have?
ICE cannot overturn legislation or act as a court.
However, it can make recommendations where service failures are identified.
Examples may include:
Apologies
Recommending a formal apology.
Corrective Action
Recommending that records be reviewed or corrected.
Reconsideration
Recommending that certain issues be looked at again.
Financial Redress
In some circumstances ICE may recommend special payments or compensation where significant maladministration has caused injustice, distress, inconvenience, or financial loss.
Service Improvements
Recommendations designed to improve future service delivery.
Evidence Standards
Strong evidence can significantly assist a complaint.
Useful evidence may include:
CMS Correspondence
- Letters and emails.
Payment Records
- Bank statements and payment confirmations.
Complaint Records
- Copies of complaints and responses.
Shared Care Evidence
- Court Orders and parenting records.
Timeline Of Events
- A detailed chronology of what happened.
Subject Access Request (SAR) Records
- Information obtained from CMS or DWP.
Advanced Claimant Protection
Parents should understand that they have important rights when dealing with public authorities.
Right To Fair Treatment
CMS should act fairly and reasonably.
Right To Proper Complaint Handling
Complaints should be investigated properly.
Right To Transparency
Decisions and actions should be explained.
Right To Accountability
Mistakes should be acknowledged and addressed.
Right To Evidence-Based Decisions
Relevant information should be considered.
ICE And False Arrears Concerns
Many Paying Parents contact ICE where they believe:
- Arrears are inaccurate.
- Payments have not been credited.
- Direct Pay evidence has been overlooked.
- Complaint responses failed to address concerns.
ICE may investigate how CMS handled the issue and whether proper procedures were followed.
However, where the dispute relates to an appealable decision itself, appeal routes may also need to be considered.
Using A Subject Access Request (SAR)
Many parents submit a Data Subject Access Request before approaching ICE.
This may provide access to:
- Internal case notes
- Payment records
- Complaint records
- Decision histories
- Telephone call records
These records can strengthen a complaint.
Relevant Legislation
Key legislation and principles include:
- Child Support Act 1991
- Child Maintenance and Other Payments Act 2008
- Human Rights Act 1998
- Data Protection Act 2018
- UK GDPR
- Principles of Good Administration
- Public Law Principles of Fairness and Accountability
These frameworks support transparency, procedural fairness, and accountability.
Accountability Framework
CMS remains accountable through:
- Internal Complaints Procedures
Independent Case Examiner (ICE)
Parliamentary & Health Service Ombudsman
Information Commissioner's Office (ICO)
- Independent Tribunals
- Courts
- Parliament

Key Message
The Independent Case Examiner (ICE) is one of the most important independent safeguards available to people who believe the Child Maintenance Service or Department for Work and Pensions has failed to provide an acceptable standard of service. ICE does not replace appeal rights or tribunal processes, but it can investigate service failures, maladministration, delays, poor communication, lost documents, and complaint handling concerns.
For Paying Parents in particular, ICE can provide an important route of accountability where concerns exist regarding false arrears, missing payments, ignored evidence, or failures within the CMS complaints process. Strong evidence, accurate records, and a clear chronology of events are often the foundation of a successful complaint.
