What it means
A contractor may need an excavator for three weeks but not enough work to own one, so it can hire the machine for the required period and gain access without the upfront purchase price. The Construction Equipment Association describes rental as a way to cover short-term projects and peak demand alongside owned fleets, which is one use and not proof that hiring always costs less, so compare the complete project economics.
Plant here means machinery and not a factory building or vegetation, and it can include generators, access platforms, cranes and other equipment, so specify exactly what is supplied. Dry hire commonly means equipment without an operator and wet hire commonly includes an operator, and Sprintlaw's Australian guidance explains the distinction and the different operational responsibilities in that jurisdiction.
Do not assume fuel, transport or insurance are included merely because the term says wet hire, so read the quote and contract, since local usage of the terms and site arrangements can vary. Wet hire can bring specialist skill with the equipment, but the site still needs to coordinate access and hazards, and providing an operator does not transfer every safety duty away from the customer.
A fictional contractor hires a crane for 21 days at $2,500 per day plus $3,000 transport, so the simple stated cost is $55,500 before other charges, and idle days may still be billable. Hire periods may be daily, weekly or monthly, and a rate can include usage limits, overtime or minimum periods, so record the start, stop and return process.
A fictional building site that finishes excavation early but leaves a hired machine parked for two weeks keeps paying under the hire terms, whereas a formal off-hire notice could have stopped avoidable charges. Transport can be a substantial cost for heavy equipment, so loading, permits, delivery windows and collection should be planned, and a cheap daily rate may be expensive for a brief distant job.
The hirer should inspect condition at handover and return, since photos, operating hours and damage records can prevent disputes, and the supplier's maintenance duties and hirer's use obligations need clear allocation. Safety is not merely an item in the price: operators may need training or licences and equipment must suit the site, so a fictional warehouse hiring forklifts for a seasonal peak still has to check driver competence, battery charging and maintenance response, because extra machines do not create safe capacity by themselves.
Plant availability can change quickly, so a project manager should confirm delivery and support arrangements before building a critical path around a hire, and the contract may offer a replacement process for breakdowns. A fictional road contractor hiring one specialist machine would see a scheduled shift stop if it broke down, so it checks response times and backup availability rather than relying only on a low rate.
A weekly plant register showing site, job, operator, rate, planned return and actual use makes idle equipment visible and helps finance allocate costs to projects. Hiring versus buying depends on utilisation, financing, maintenance, storage, resale and flexibility, since a machine used consistently across projects may justify ownership while a rare tool may not.
A simple comparison estimates hire days times full daily cost against annual ownership costs at expected usage, including downtime and operator needs, and not only the purchase price. For accounting, some hire arrangements may be leases under IFRS 16 or another applicable standard, and duration alone does not settle the classification, so review the identified asset, control and any exceptions with an accountant; plant hire offers flexibility when the scope and terms fit the work, so control cost by planning delivery, safe operation and prompt return.
In practice
Real-world examples.
Example
A contractor hires a mobile crane with an operator for a short lift.
Example
A warehouse hires forklifts without operators for its seasonal peak.
Example
A site formally off-hires an idle excavator when excavation ends.
Formula
Calculation
Illustrative hire cost = agreed rate x billable period + transport, operator, fuel and other chargeable items under the contract. Compare with total ownership cost at expected use.
Worked example for an invented contractor. A crane is hired for 21 days at $2,500 per day with $3,000 transport.
- Hire charge = 21 x $2,500 = $52,500.
- Total = $52,500 + $3,000 = $55,500.
- If the crane is idle for 4 of those days but still billable, idle cost = 4 x $2,500 = $10,000, so a timely off-hire notice matters.
- If a similar crane cost $600,000 to own, with annual ownership costs of $90,000 and expected use of 150 days a year, ownership costs $90,000 / 150 = $600 per day of use, well below $2,500, so hire only wins when expected use is low or irregular.Case study
Seen in the real world.
In this fictional example, Stonebridge Civil hires excavators for several sites. A weekly register reveals that one machine remains billable after its task ends. The manager returns it and clarifies off-hire notices for future projects. The team also checks safety and transport terms before signing new hires.
Watch out
Common mistakes.
- Assuming wet hire always includes fuel and every site responsibility.
- Leaving idle machines on hire after work ends.
- Comparing only daily hire with the purchase price.
Questions

What is dry hire?
Usually equipment without an operator, subject to the contract.
When should a business buy instead?
Compare full ownership and hire costs at realistic usage and flexibility needs.
Is every hire a simple operating expense?
Not necessarily. Check the relevant lease-accounting standard and contract.
