Plant hire rarely follows the original programme exactly. Extra days, changed attachments and different workfronts can alter both the equipment requirements and the commercial arrangement. A simple change record keeps the site, hire desk and accounts team working from the same version.
Identify the change before ordering it
Describe what is changing, why it is needed and when it must take effect. Reference the existing machine and order. Separate a time extension from a changed task: keeping the same unit longer does not answer whether it suits new work.
Ask the responsible technical team to review suitability where the task, attachment or location changes. Keep the supplier's confirmation with the change record. The person approving cost may not be the person authorised to assess the equipment.
Name the approval channel
Record who can request a variation and who can accept revised charges. Give the supplier a reliable contact so an urgent request does not disappear between the site and procurement team. Keep verbal discussions followed by a concise written record.
Ask for the effective date, revised rate, transport impact and any changed included hours. An extension should identify the new expected return date. A machine swap should identify what leaves, what arrives and how the handover is recorded.
Example: moving to a second workfront
The crew finishes one area early and wants to move the hired unit to another project. Before relocation, give the supplier the new address, task and timing. Confirm consent, transport, support and any different site requirements.
Record the meter and condition at the transfer if the agreed process requires it. Keep the two work packages distinct for cost tracking. A supplier's wide service area does not itself approve an unnotified relocation.
Close changes at invoice time
Link every accepted variation to the relevant invoice period and order. If a requested change was cancelled, retain the cancellation acknowledgement and any agreed charges. This prevents an obsolete request from appearing later as an unexplained cost.
Review recurring changes after the hire. Frequent extensions may indicate an optimistic programme, while repeated attachment additions may point to an incomplete brief. Use that pattern to improve planning rather than creating a more complicated approval process than the work needs.
Common questions
Is a phone call enough to extend hire?
Use the supplier's agreed process and keep a written acknowledgement of the new term and charges after the conversation.
Does a longer hire permit different work?
Not automatically. A changed task, attachment or location may require a separate suitability and commercial review.
