Visibility for non-commercial UK entities
The .org.uk extension is second-level to the .uk extension. And the .uk extension is one of the top ten most used on the web today – which means that a .org.uk domain is sure to be highly visible. UK citizens trust the .org.uk extension, because so many charities and non-profit groups use it. If you're a non-profit, your audience no doubt expects to find your site with a .org extension of some kind. In sum, if you're a non-commercial entity in the UK, a .org.uk domain name is exactly what you need.
