I have had NHS hearing aids for years, current aids are Bluetooth enabled and l find them very good, excellent in fact. I cannot fault NHS audiologists but my last set of hearing aids were dreadful. The waiting time to see an audiologist in my current health authority is appalling. I held out purely on financial grounds and waited for 18 months (for replacement aids). It is extremely important to wear aids if you need them, dementia risk can increase if you don't.
Check with you GP what the waiting period is and if it doesn't suit you seek help elsewhere.
