Sorted - been a very long day.

I didn't need to decode the response in the end so the following will work (hopefully it helps someone else doing the API integration)

function PrintLabelRequest($shipmentNumber, $transactionId)
{
   $rm = new RoyalMailLabelRequest();

   // function from library returns a response using SOAP
   $response = $rm->PrintLabel($shipmentNumber, $transactionId);

   // name the file & saved this label as a PDF in the following folder
   $filename = 'printedlabel-' . $shipmentNumber;
   file_put_contents(dirname(__FILE__) . '/labels/'. $filename .'.pdf', $response);
}
