Ive contacted a private consultant near me and its looking like £225 for the first consultation which doesnt include any tests, another £275 for the nasal endoscopy and another £150 for a hearing test. Ive replied asking what I get for the first consultation. My worry was this would get expensive very quickly which seems to be the case from this first information. I have another person to try though.
Edit - 2nd quote recieved. £160 for first consultation again with no tests plus £167 (plus unspecified hospital fee) for endoscope test.
I think its looking like the best part of £500 just to get the initial examination including the nasal endoscope.
