About Us

The IWF was established in 1996 by the internet industry to provide the UK internet Hotline for the public and IT professionals to report criminal online content in a secure and confidential way.
The Hotline service can be used anonymously to report content within our remit.
We work in partnership with the online industry, law enforcement, government, and international partners to minimise the availability of this content, specifically:
  • child sexual abuse images hosted anywhere in the world*
  • criminally obscene adult content hosted in the UK
  • non-photographic child sexual abuse images hosted in the UK.

The IWF is a membership organisation and became a registered charity in 2005 with an independent Board


The key to our success since our inception is the support we receive from the online industry and strong partnerships we have across the globe. We strive to meet the demands of evolving technology, industry developments, and public and government scrutiny.

If you would like to join us as a Member, or work with us as a partner, please get in touch.
We help internet service providers and hosting companies to combat the abuse of their networks through our ‘notice and takedown’ service which alerts them to content within our remit so they can remove it from their networks.
We also provide unique data to law enforcement partners in the UK and abroad to assist investigations into the distributors. As a result of this approach the content we deal with has been virtually eradicated from UK networks.
As sexually abusive images of children are primarily hosted abroad, we facilitate the industry-led initiative to protect users from inadvertent exposure to this content by blocking access to it through our provision of a dynamic list of child sexual abuse web pages.


  • By sharing intelligence with police the IWF aids the identification and rescue of children;
  • 0.3% of child sexual abuse content is hosted in the UK (it's been less than 1% since 2003), down from 18% in 1996;
  • All UK hosted child sexual abuse webpages are removed within 4 days;
  • 84% of child sexual abuse webpages are removed within 10 days;
  • Over 500,000 web pages assessed in 19 years;
  • 100,000 URLs removed for containing criminal content.


We are an independent self-regulatory body, funded by the EU and the online industry, including internet service providers (ISPs), mobile operators, content  providers, hosting providers, filtering companies, search providers, trade associations and the financial sector. Our self-regulatory partnership approach is widely recognised as a model of good practice in combating the abuse of technology for the dissemination of criminal content. 

Sharing Good Practice

We work with UK government to influence initiatives developed to combat online abuse and this dialogue goes beyond the UK and Europe to promote greater awareness of global issues, trends and responsibilities.
We work internationally with INHOPE Hotlines and other relevant organisations to encourage united global responses to the problem and wider adoption of good practice in combating child sexual abuse images on the internet.


There are a number of tactics carried out by the IWF on a national and, where relevant, international basis which minimise the availability of child sexual abuse content online:
  • Reporting mechanism for the public to report any inadvertent exposure to potentially criminal child sexual abuse content.
  • Using intelligence-based methods to proactively search for child sexual abuse content (new since April 2014)
  • ‘Notice and takedown’ system to swiftly remove child sexual abuse content at source in the UK.
  • Targeted assessment and monitoring system to remove child sexual abuse content in newsgroups.
  • Provision of a child sexual abuse URL list to internet service providers, mobile operators, search providers and filtering providers to help disrupt access to child sexual abuse content which is hosted outside the UK and not yet taken down.
  • Working with domain name registries and registrars to deregister domain names dedicated to the distribution of child sexual abuse content.
*Please note that 'child pornography', 'child porn' and 'kiddie porn' are not acceptable terms. The use of such language acts to legitimise images which are not pornography, rather, they are permanent records of children being sexually abused and as such should be referred to as child sexual abuse images.
