The code I used at the moment

<?php $current_term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) ); ?>
<?php $cats = wp_list_categories( array(
    'orderby' => 'id',
    'child_of' => $current_term->term_id,
    'taxonomy' => $current_term->taxonomy,
    'hide_empty' => 0,
    'hierarchical' => true,
    'depth'  => 2,
    'title_li' => ''
    )); ?>
