For me the company supply:
Laptop with diagnostic leads & software
Curtis handheld unit
Lifting equipment like jacks, blocks, slings, chains & spreader beam.
Grinder, 2 x drills ( 1 mains & 1 battery )
Torque wrenches ( as they insist on having them calibrated every 6 months )
Any PPE ( Personal Protective Equipment ) like safety goggle's, boots, apron, dust mask, hi viz vest, gloves etc - well there legally required to provide PPE in the UK.

Everything else the technician is expected to supply, the company does insure the technicians tools for theft & will also replace anything broken in the line of duty.

As part of the deal for buying a new fleet of forklifts from a manufacturer the software, cables & training on the software are part of the overall deal.
