They will decide upon receiving your application whether to issue you with a 1, 2 or 3 year licence, recognising hypo's and not needing a third party assistance in dealing with them is a plus so your on the right tracks.
It may take some time for them to get back in touch, however if you have concerns then contact the DVLA helpline, I renewed mine earlier this year and it took them around 8 weeks for them to issue my licence, this was because they were doing some checks but usually it only takes around 4 weeks.
