Is HGV/LGV driving worth it?

I’m probably going to spend the guts of a couple of grand on acquiring my C and C+E licences later in the year. View these as a valuable insurance policy.

Get a bit of time off on my regular job so have used agency van driving job to fund my training and all other expenses (books, DVDs as well as theory/practical training + tests).

Will then hope that agency will provide me with valuable experience when I pass - can then decide if I want to continue with my current employment or switch to driving f/t - even though the permitted hours of work look quite limited in this day and age.
