Why are websites being blocked in the UK?

Mobile and broadband Internet Service Providers (ISPs) apply filters to stop under 18s from seeing harmful content online. Unfortunately, filters block many harmless websites by mistake - even sites that are aimed at children! Often website owners don't know that this is happening.

Filters are often switched on by default not choice. This means that millions of people may not be able to see a site that is incorrectly blocked.

Anyone can use the Blocked tool to check and report sites that shouldn't be filtered. It helps website owners and increases transparency about the impact of filters.
