Hi Gethin,

You can use this code:

function wooco_products_first_check() {
    if ( is_product() ) {
        ?>
        <script>
        jQuery(window).load(function(){
            if(jQuery(".wooco_components .wooco_component:not(.wooco_component_required) .wooco_component_product_checkbox input[type='checkbox']").length > 0){
                jQuery(".wooco_components .wooco_component:not(.wooco_component_required) .wooco_component_product_checkbox input[type='checkbox']").prop('checked',false).change();
            }
        });</script>
        <?php
    }
}
add_action( 'wp_footer', 'wooco_products_first_check');
