Actually saggit, if the background checks are complete then PCC may not be required. But I got it made last week and sent it today as it got expired in the first week of June. Initially I had thought to keep it with me and give it immediately when they ask, as you understand making a PCC is such a complicated thing in Pakistan where as submitting medical is easy. But then I sent it as I unfortunately didnt hear any thing from them. As for Caips notes, I ordered that in Nov, 2010 and got it in December. Now I have ordered it again like say yday, I sent my husband all the forms filled and scanned, he is likely to order it today. By the time I will receive those notes, I am hoping to have got the PPR. Yeah I know, you are in a worse situation then even me that you have not got any correspondence.
I would recommend you to speak to your MP, not that an MP is great but sometimes it really helps..All the best
