this isn't my experience of registration. you can declare a vehicle as no longer a road vehicle. l used to race motorbikes. when I purchased a new bike to race, the dealer had already registered it (It's how they maintain sales figures or something) I called dvla to establish my position on SORN to be told I had to renew this every year! I pointed out the bike would never be on the road & in effect was no longer a road vehicle but they were insistent. After speaking to a Pro race team i discovered I was allowed to de-register the bike with dvla, which i eventually managed to do.

I'd read about this issue countless times over the last few years. The attitude of dvla is outrageous given the number of people effected by this. losing HGV entitlement means losing your living! the arrogance of these people to place the onus on the driver, given the number of cases like it is unreal. It's obvious there is a problem with the way they are storing /processing our personal data which violates data protection laws in itself. But being a government agency i guess they believe the law doesn't apply to them! I've just had to apply to change my address & would rather pay the fee to replace a lost licence so I can keep the original. Luckily I came across my pass certificate for bike entitlement when moving too. It's 12 years old now & I never thought I'd need it again. But it seems dvla incompetence has proved me wrong.
