Yes - but not on all items.
For customers that do not have a credit account with us, we do also take a security deposit in addition to the hire fee before the equipment is released. This is typically just for high-value items (such as earthmoving machines) or concrete grinders (which can attract additional charges for excess diamond usage).
Once the equipment has been returned, we will inspect it/refuel it etc and return the deposit minus any additional charges (like fuel/damage/cleaning charges).
