Making a lightweight website


The NHS website primarily uses headings and text without images.

This makes the website very lightweight so it doesn’t use much data and is able to load over poor connections.

Key guidance

Use headings to provide clear structure to pages.

Use a free tool like Google’s PageSpeed Insights to understand how your website performs and how long it takes to load pages.


  • Using images can help people to understand and relate to your information, but can slow down performance. Use them sparingly where they will have the most impact and make sure they are the right size.
