You can complain to us if you:

  • think there is something wrong with an ad you have seen or heard
  • think a special offer, competition or prize promotion has been unfairly run
  • want to stop direct mail from companies, sent by post, text message or email

If you want to report an online scam ad, please use our scam ad reporting form.

How to complain

  1. Check below whether your complaint is something we can deal with. We regulate most ads and promotions across media – but not all. Where we can’t deal with your complaint, we try to suggest another organisation that may be able to help.
  2. Ensure you can give us details about the ad, including where and when you saw or heard it. If we don't have enough information to help us to find the ad you have concerns about, we may not be able to proceed with an assessment of your complaint.
  3. If possible, have ready a photo, video or screenshot of the ad to submit. Many devices, including smartphones, allow screen recording that captures the content in full, including any audio.
  4. Be ready with an explanation about why you object to the ad, highlighting specific claims or images if relevant. Please limit your complaint to three issues only.

Please note, we don't accept anonymous complaints, so you'll need to provide your name and contact details.

If you work for a competitor of the company you are complaining about, you'll need to provide evidence to show that you have followed our inter-party resolution process.

Targeted online advertising (Online Behavioural Advertising – OBA)

Some online ads are personalised based on your browsing activity. This is known as Online Behavioural Advertising (OBA).

Third parties, such as ad networks, collect information about the pages you visit, the ads you click and the searches you make. They do this using cookies placed in your browser. The aim is to show you ads that are more relevant to you.

This type of advertising does not use information that directly identifies you as an individual.

Businesses must make it clear when they are using OBA and must provide a way for you to opt out.

If you want to complain about OBA – for example, if an opt-out hasn’t worked – please provide:

  • the address of the website you were visiting
  • if known, the name of the ad network delivering the ad
  • a screenshot of the ad or the URL of the webpage (you can upload this as an attachment)
  • if the ad included a notice about OBA, a screenshot of the page the notice linked to
  • the name of the browser you were using
  • confirmation of whether you have tried to opt out

You can find more information about OBA and opt-out mechanisms on Your Online Choices. You can also visit aboutcookies.org to learn more about how cookies work and how to change your browser settings. 

Concerns about the use of cookies more generally should be raised with the Information Commissioner’s Office (ICO).
