    . However, I’d like to display this in a list/hierarchical tree.

    Any help greatly appreciated.

    Love Pete x

    This is what I have…

    <?php
$taxonomy = 'category';

// get the term IDs assigned to post.
$post_terms = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );
// separator between links
$separator = ', ';

if ( !empty( $post_terms ) && !is_wp_error( $post_terms ) ) {

	$term_ids = implode( ',' , $post_terms );
	$terms = wp_list_categories( 'title_li=&style=list&hierarchical=1&echo=1&taxonomy=' . $taxonomy . '&include=' . $term_ids );

    Your post got clipped, but I think I understand what you want. You need to edit down the if(){} block to this:

    if ( !empty( $post_terms ) && !is_wp_error( $post_terms ) ) {
	$term_ids = implode( ',' , $post_terms );
	wp_list_categories( 'title_li=&style=list&hierarchical=1&echo=1&taxonomy=' . $taxonomy . '&include=' . $term_ids );
}

    everything above the if line remains the same.
