How to incorporate a previously privately owned and second-hand light goods vehicle into a new sole proprietor?

How do I incorporate a previously privately owned and second-hand light goods vehicle into a new sole proprietor?

In 2019, I purchased a second-hand light goods vehicle. At the end of the previous year, I started working as a tree surgeon as a secondary occupation. This van, which I already owned, is now my company vehicle. I can roughly determine the current value of my van by comparing similar second-hand offers on the internet.  (Once the van has been included, I assume that all running costs can simply be entered . Road tax / garage costs / fuel, etc.)
