Our hearing care professionals

In 2005, Hidden Hearing became the first dedicated hearing retailer to be recognised as an Investor In People, and we were re-accredited in 2008 following an independent assessment. By encouraging our employees to be actively involved in the company, and developed to their full potential, we can pass the benefits directly to you, our customers.

On 1 April 2010, the registration of hearing aid dispensers was transferred from the Hearing Aid Council to the Health and Care Professions Council, meaning that hearing aid dispensers have now joined a body of professionals that includes chiropodists and paramedics on the Register for Healthcare Professionals. All of our hearing aid dispensers are members of the Health and Care Professions Council.
