What you might or might not get from the NHS depends on where you live, I live in South Yorkshire and am ONLY entitled to ONE hearing aid even though I may need two, across the border in NE Derbyshire you get TWO hearing aids if you need them.
When I went to my GP to have my hearing problem looked at, their first question was "why haven't I been to a high street audiologist", with the presumption that I should pay for hearing aids.
So, I was eventually refered to the NHS and got my ONE hearing aid which worked well fort a while but me hearing deteriated to the point I needed two hearing aids, so bit the bullet and purchased new ones.
The difference is amazing, the Bluetooth connectivity is great.
The device everyone seems to be talking about is for those that do not have Bluetooth conectivity in their TV, my Samsung TV has blue tooth audio but I do not use it as I do not watch TV, I connect to my computer via blue tooth and watch what I need on that.
As an aside, forum members may not have seen an article (can't remember where I read it) recently that has linked common chemotherepy medication for certain types of cancer to hearing loss.
The hearing loss seems to kick in at or around the 5 year mark after receiving chemo treatment.
As I read the article everything seemed to drop into place as pointing to the chemo as the cause, I may be wrong of course but my hearing loss started being noticable in 2019/20, I started my Chemo in 2014.
Of course it could just be old age.
Ahhhh! it gets us all in the end
