“William Duncan and Co have been our auditors for over 20 years. During this time we have worked closely with Duncan’s on a variety of audit, financial and taxation matters, they understand our business intimately, and although they have always managed to keep a continuity of audit staff from year to year, they also have considerable depth of resource, which allows them to provide not just audit, but other services – they are flexible, and we have always been impressed with the quality of their work.”
