Temp licence tend to run for people who have been classed as misuse/dependence confirmed by a medical report from your own GP, as an HRO you may be subjected to investigation through your own GP to see if there are any alcohol issues documented with your GP that can raise serious concerns, these investigations will go back six years but not limited to and may include mental health investigations too, however if you do have any issues that you think might be of concern to the DVLA then now would be a good time to visit your GP in preparation for when you do apply for your D1, many folk are under the impression that once a DVLA medical has been attended with a low reading then their licence should be returned to them, but in fact it is upto the HRO to prove through your GP that you are medically fit to drive with the help of LFTs if needed, if there are concerns and you are addressing them now then you will be in a very good position to receive your licence without the need for a revocation, depending on your circumstances the DVLA managers will decide on what licence to issue nearer your time, a temp licence can run for six years with the licence holder attending medicals every year if needs be , until DVLA are satisfied you are no longer pose an alcohol issue......people who are revoked do not have to pay but I believe HROs do.....
