If you want to make a complaint then you should do so within three months of receiving our service. Waiting longer than that could affect our ability to look into your complaint. In some cases, a long delay will mean that we will not consider the matter at all.
We will acknowledge your complaint within 10 working days. In most cases, the person who dealt with you will first check to see if they can resolve your complaint by providing you with further information or clarification about any decisions they have reached. If they can't do that, they will share your complaint with an appropriate reviewing officer, who will look at what we have done and why.
Once a reviewing officer has considered your complaint, they will tell you what they have decided. The reviewing officer should reply within 30 calendar days of the complaint being raised with them.
The Information Commissioner will not respond to your service complaint personally, even if you write directly to her. She has delegated responsibility for reviewing our service in specific cases to reviewing officers.

Taking your complaint further
If, having exhausted our case review and service complaints procedure, you remain dissatisfied about any aspect of any service you have received from us or think we have not acted properly or fairly, you can take the matter to the Parliamentary and Health Service Ombudsman.
Complaints to the Ombudsman must be made through your MP. For further information about the Ombudsman’s service please visit their website (www.ombudsman.org.uk) or call their helpline on 0345 015 4033.
If your complaint relates to the way in which we have interpreted the law then the Ombudsman cannot help you. If you want to challenge our interpretation of the law, you should consider seeking legal advice.
