Include the post type before the title of search results

I solved this by copying the divi index.php and placing it in my child theme as search.php

I then found where the title and altered it with the below code:

<h2 class="entry-title">
<a href="<?php the_permalink(); ?>">
<?php $post_type = get_post_type( $post->ID );
echo $post_type . ": ";
the_title(); ?>
</a>
</h2>

Probably not the correct way to do it but the result was perfect. My search results now have:

Blog: ‘Blog title’

Page: ‘Page title’

etc
