Answer 1

The code of this answer: How to get minimum order amount for free shipping in woocommerce
is obsolete with WooCommerce version 2.6+, but it was helpful for this functional answer…

After making some search and some tries, I have found the way to get the minimum Order amount that is set in the Free Shipping method, for a specific Zone (Region):

Here is the working tested code (explanations are commented inside):

// Here you get (as you already know) the used shipping method reference
$chosen_methods = WC()->session->get( 'chosen_shipping_methods' );

// Replacing inside the string ':' by '_'
$option_value = str_replace(':', '_', $chosen_methods[0]);

// We concatenate the string with additional sub-strings
$option_value = 'woocommerce_'.$option_value.'_settings';

// Just a test => outputting the string to see what we get
echo $option_value; echo '<br>';

// Now we can get the options values with that formatted string
$free_shipping_settings = get_option( $option_value );

// Just for test => we output the (pre-formatted) array of values to check
echo '<pre>'; print_r($free_shipping_settings); echo '</pre><br>'; 

// Here we get the value of the order min amount (Finally!)
$order_min_amount = $free_shipping_settings['min_amount'];

// We output the value (to check)
echo 'Order min amount: '.$order_min_amount;

Bingo! you get it.

Right way for get this..

function get_free_shipping_minimum($zone_name = 'England') {
    if ( ! isset( $zone_name ) ) return null;

    $result = null;
    $zone = null;

    $zones = WC_Shipping_Zones::get_zones();
    foreach ( $zones as $z ) {
        if ( $z['zone_name'] == $zone_name ) {
            $zone = $z;
        }
    }

    if ( $zone ) {
        $shipping_methods_nl = $zone['shipping_methods'];
        $free_shipping_method = null;
        foreach ( $shipping_methods_nl as $method ) {
            if ( $method->id == 'free_shipping' ) {
                $free_shipping_method = $method;
                break;
            }
        }

        if ( $free_shipping_method ) {
            $result = $free_shipping_method->min_amount;
        }
    }

    return $result;
}
