My LGV class 1licence expired some years ago & thinking a bout driving trucks a gain.
Is it easy to get my entitlement back ? .
I realise I will need to have a medical & do some dcpc training etc .
Thanks

And that’s it. For cpc you should have the option of 35 hours OR the initial qualification which is a theory test and a practical demonstration test. Upside of that is that it takes less time. Downside is that it’s pass/fail. 35 hours, delivered properly, will be good for you to update the information you have tucked away in the back of your head somewhere.
All the best, Pete 
If you originally passed what was then HGV before 1983 then you might have DVLA issues as those records did not get computerised
