What is a private hearing aid dispenser?

We are all registered by the HCPC. The licence required allows us to prescribe and sell hearing aids in the UK. It’s extremely straight-forward to program hearing aids. Be aware of anyone suggesting that they have additional qualifications.
A related BSc or MSc is of value. As is a doctorate, experience in an ENT department, experience in GP Practice in removing ear wax, or experience in a GPSI ENT practice.
I can say with great conviction that professional experience, time and patience are very important in grading successful outcomes with hearing aids.
