I can definitely recommend specsavers, you will probably be given them the same day you are tested because as you have a mild hearing loss you will probably be given the Seimans open fit aids so you will not need to have an impression taken for moulds. These are very discreet and very light to wear. Free batteries, advice and help whenever you need it and free replacement (s) and servicing when necessary -really what's not to like? You will be advised to use them for a week or so and be given an appointment to go back and have them tweaked, if necessary. Then you can decide if you need additional things added i.e. loop system etc. (depending on the model they give you of course) If you go private, as you have found out they can be VERY expensive + batteries and servicing is at least £75. The NHS are so busy if you have any problems at our hospital they have a walk-in clinic twice a week and you can sit in there for about three hours waiting to be seen whereas you will have an appointment at S/S within the week I expect.
No -I don't work for S/S just have had years of paying out privately and waiting and waiting to be seen by the NHS so I'd say give them a ring, you have nothing to lose -good luck- rosy
