Gov.uk style components
Navigation links are used as an easy way to navigate a lot of pages, it's particularly useful for grouping pages/topics together, as it orders content numerically. They also help to bring information to the forefront, rather than having layers of navigation for a user to click through.
We have used navigation links on these pages, you can also see an example of navigation links on our Council Tax Support page.
Related documents and links
On the right hand side of the page you can list related documents and links. This is a good area to display additional information that your user requires. We would advise any core information the user needs is added to the main content, as an external link or document. However supplementary information should be added on the right hand side. On the right hand side of this page I have added links to the other pages on our components, and our user guide.
