If you are aplying for a license, you MUSt report any hypo unawareness on the form, and if you do, you don't get the license, it also states that if you are diabetic, if at any point you experience unawareness, you must report it immediately. At that point your license will be taken from you.
"If you suffer from hypo unawareness, that is you have difficulty recognising hypo warning symptoms, the DVLA states that you should not drive.
If hypo awareness recovers, you may resume driving but the recovery of hypoglycaemia awareness must be confirmed by a consultant or GP."
It is your responsibility to do this and if you carry on driving, asi said above you will be uninsured.
