ESA50 form time until medical

Hi, I have just been transferred to PIP from DLA , from middle care and lower mobility DLA to enhanced care with 17 points on PIP for 4 years(received only 4 points for mobility). All in all this stressful period lasted from April until September. I had the medical in June for PIP and received a positive result 8 weeks later.

Now only a week after receiving my PIP rate, the post decided to land the ESA50 capability for work questionnaire! This has to be returned by October 7th. My question is how long from sending it back until medical? If say I sent it back at the latest possible time. I have been in the support group since being transferred in 2011 from incapacity benefit to ESA and this will be my 3 rd medical when I eventually receive a date for it. In the past it usually has taken 3 to 5 months , I am in the Bristol area.

Now getting to the point, I am going to Scotland early November to spend time with family I have not seen for a very long time and I will not be back until just before Christmas. If I am away , is there any way to rearrange a medical? My neighbour will be checking my mail to let me know and my support worker has said he will call them if need be. I just know I'm not going to be able to relax and cope when I go away because of this, which was the whole point of this trip that's been planned. Thanks.
