Illustrations are visual symbols used to bring the warmth of British Gas brand and personality to the website.

Illustrations simplify products and services to users in a friendly manner. Illustrations always accompany content.

Considerations of best practices#

When choosing an illustration from the available set in Nucleus, it should be relevant to the content. Each has a descriptive name to help aid selection. (See Usage below).

Avoid unnecessary duplication of an illustration on a page. Be aware of existing usage elsewhere.

  • If you pass an empty size the icon will fill the parent element


  • This is for decorative purposes only (does not work in IE11).

Creating new illustrations#

If you are looking to create a new illustration, please check if there is not something similar already in use. If there is no suitable option, liaise with the brand team to define a new one and let us know so we can help with the required specification for adding it to the design system.

Read our illustration foundation page for more information on creating illustrations.
