getting copies of the assessors reports

Last week I had a PIP assessment at home. I want to get a copy of the assessors report, but don't know what I need to ask for. Has the report got an official designation, or do I just ask for 'a copy of the assessment' or 'the assessors report'.

Also, who do I ask - the DWP or the company that did the assessment, in this case Capita.

On a similar question, when I made my initial claim I asked for a copy of everything the DWP had on my claim - I have been on DLA for sixteen years, indefinite for the last ten. They never sent this information to me despite me phoning a second time a week after the initial phonecall and asking again - when I was told they were organising it. Fortunately I have quite a lot of stuff I could send in my evidence pack.

Are the DWP legally obliged to send me this stuff when asked for, or can they just not bother? Am I likely to get the same non-response to a request for the assessors report? And if I have to ask for MR or go to appeal, will they then have to send me everything they use to make their decision?

Thanks for any help.

Thank you I'll get in touch with them and request the report.
