First check with you specialist, or their secretary that the report has been sent, politely. If so then call the CAA medical lot (general number, press 1 then 2, I think) and ask the person at the end of the phone where your file is!
Given that you have a class one you should not have to wait too long for an answer to this.
The CAA SMO may not have the required knowledge and may be waiting for a CAA recommended specialist to consult with. Usually less than interested in the CAA apart from the money that this side-line offers. Many have very little working knowledge of pilot requirements and therefore have totally inconsistent views regarding our medical restrictions. Therefore I hope you have a good SMO looking at your case.
Personally I find the whole bunch of them somewhat archaic.
