Recording Capita F2F interview

Hi, I recall reading information regarding this over the last year, but now its my turn for home interview on 26th November. I had asked for paper based report, as the DWP recommendations state that individuals which should not require a f2f are those with "strong evidence on which to advise on the case and a face-to-face consultation is likely to be stressful for the claimant (for example, claimants with autism, cognitive impairment or learning disability)"

I sent 17 reports from Hospital Consultants, Psychiatrists, Physiotherapist, Social Worker, GP reports both recent and historical. I have Autistic Spectrum Disorder (Aspergers), Social & Generalised Anxiety Disorder and struggle with Self Harm when stressed. I was pretty sure I'd not be asked to have a F2F... I'm going to try getting a letter from a private GP stating it would be detrimental to health. NHS gp doesn't do this anymore. I take opiod painkillers for spinal & joint pain which makes me dopey, I'm terrified I'm going to mess up the interview...

I told Capita this evening that I would be recording the interview, I said I purchased 2 identical voice recorders & tapes, but they insist it has to be a single recording device capable of producing 2 tapes / CD's and that such a device is available in Argos - I searched under every heading and nothing like that exists in Argos. However Capita website states:

"Your recording equipment must be able to produce two identical copies of the recording at the end of the assessment" so surely my 2 dictaphones would fulfill this requirement?

(This is the Northern Ireland branch of Capita.)

Thank you so much Gordan, I wouldn't have thought about confirming it in writing.
