Within the UK, the NHS provides digital BTE hearing aids to NHS patients, on long-term loan, free of charge. Other than BAHAs (bone anchored hearing aid) or cochlear implants, where specifically required, BTEs are usually the only style available.

A bone-anchored hearing aid (BAHA) [2] is a type of hearing aid based on bone conduction. It is primarily suited for people who have conductive hearing losses , unilateral hearing loss , single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.
