Companies have become far more dubious about taking on 'new' LGV drivers. When I passed my test 20 odd years ago, the accepted route to gain some experience was to become an agency driver. Loads of different sorts of vehicles, but not much pay. Nowadays, big fleets (supermarkets etc) don't just use agency drivers as a stop gap to cover illness, holidays etc, but can more or less staff their drivers through agencies. As such, it is a lot harder to get a drive without experience. You are best to train nowadays with your future employer. I would suggest looking in the local paper for any firms looking for drivers and ask them if they will train you up. Most supermarkets train their own drivers, so if you have depot near you, try them.
