Speaking from experience (doing 60 mph on the approach to Dartford crossing, had done for years despite the 50 mph signs got caught opted for the speed recognition course only to get the info in the post and realised my licence would expired before the course date so had the dilemma of current licence valid but by the time the course came around my licence would invalid. Should I renew and send off my previously valid licence or risk having no paperwork to show at course and be penalised. Anyway this had nothing to do with the question answered because lets talk about me
I did find the course useful and as a result have looked at my driving with a fresh pair of eyes I see a lot more potential for an incident to occur and take pre meditated defensive action before an accident happens it will give you if willing to learn long range hazard perception.
However it is like taking candy from a baby and with the public finances in free fall the motorist is looking like an easy picking who would of thought that the state would turn into dick Turpin oh how the roles have reversed.
STAND AND DELIVER
your money or some points
But the short answer is you get one crack at the speed awareness course and it has no effect on your or anyone’s insurance so like monopoly its a get out of jail but not quite free about £90 last time I did mine
