The MEDRESCO range of hearing aids ceased in 1975 when the NHS began purchasing aids through contracts with major hearing aid manufacturers - though the models were generally distinct from those available in the private sector. This policy enabled a wider range of better quality and smaller hearing aids to become available, and the NHS to adapt more quickly to technological changes.
