Check if a site is being blocked

The easiest way to get a site unblocked is to use this site. When you have checked a URL, you can click the ‘request Unblock’ button. This will generate a report to the companies that are blocking the website. You have to enter your email address. This is because any requests have to come from an actual email address.

If you are a website owner, you can also email Internet Matters who will liaise with the four main ISPs to see if your site needs to be reclassified. You can do this by emailing and include your name, email and the URL of your site. There is more information here.

If you are not the website owner or would rather contact a company directly, the email addresses to use are as follows.

Virgin Media


Mobile companies


EE, Orange and T-Mobile
