If you are looking for an exemption, decide why. On the face of it almost all industrial estates are classed as a public road and the road traffic act could apply, including licences, insurances etc etc As it’s an fLT, class B reqd (( check reg 3(4)a MV(driving licences)Regs’99)) Insurers may have higher demands. Check DVLA. As can’t see exemption from being registered and taxed (even if it’s zero tax). It’s not a goods veh, hence no need for HGV2. Assume driven without a load. Check dimensions incase it comes under an STGO dimensions - primarily width. If so, may need to get permit for each movement!
