Your machine ran six hours. Why does the bill show a full day?

First, separate the four clocks

The word 'hours' can refer to the booking, the operator's shift or the machine itself. Start by identifying which measure appears in the quotation and which appears on the invoice. They need not match.

An engine-hour reading is not a direct measure of completed work. Engine running time can include idling. Ask what that particular meter records rather than treating every hour counter as identical.

On a small screen, scroll the table sideways. Keyboard users can focus the table area and use the arrow keys.

Find the charging basis before the rate

Ask whether the offer is hourly, per shift, daily or for a longer holding period. Then ask when that period starts: dispatch, arrival, handover or an agreed time. A daily minimum can apply even when the job finishes early, if that is what you accepted.

Many rental agreements draw this same distinction: they define a rental period separately from a one-shift usage allowance, with additional charges once that allowance is exceeded. Terms vary by supplier, so for your booking, agree the minimum, included hours and excess-hour calculation in writing.

What a six-hour day might actually mean

Illustrative fictional scenario, not RIGR policy: a renter accepts a one-day minimum with up to eight engine hours included. The machine stays on site from the agreed morning handover until that afternoon's accepted off-hire. Its meter rises by six hours. The site log records five hours working and one hour idling.

Under those invented terms, the one-day minimum still applies. The sixth engine hour is not necessarily productive work, and the two unused included hours do not become a refund unless the agreement says so.

Now change the agreement to actual metered hours with no daily minimum: the billing question changes too. The lesson is not that a full day is always correct. It is that you need the agreed basis before you can test the bill.

Separate standby from overtime

A machine waiting for material, site access or another contractor may remain on hire even with its engine off. Ask whether standby is charged, whether any reduced basis is offered, and what evidence or notice is needed. Do not assume that rain or an idle day automatically pauses rent.

Overtime is a different question. Does it mean engine hours beyond the allowance, a second shift, operator attendance outside agreed hours, or more than one of these? Confirm how each is calculated and who can authorise extra work. Report breakdowns promptly and agree how any downtime adjustment will be assessed; do not deduct it unilaterally.

Check what sits beside the machine charge

Keep equipment rent separate from operator charges, fuel, transport and other quoted items. Ask whether an operator is included, what attendance covers, and whether accommodation or travel is extra. For fuel, record the agreed supply and return arrangement rather than relying on a verbal promise of an 'all-inclusive' rate.

Some rental agreements list fuel and delivery or pickup separately from rental rates; your offer may be structured differently. Request an itemised total with applicable taxes, inclusions and exclusions so that a fuel adjustment is not mistaken for an hours dispute.

End the rental clearly and keep a short evidence log

Finishing the task is not necessarily the same as ending the rental. An estimated pickup date is not itself an end date — many suppliers require the customer to actively confirm the end of hire. Establish your own supplier's process for this up front.

Agree who receives the off-hire notice, the cutoff time, when billing stops, and what happens while collection is pending. Obtain written acknowledgement. A sensible record is brief but consistent:

• Record machine identification and dated meter and fuel readings at handover and return.
• Log work periods, waiting, breakdown reports and the people notified.
• Keep approvals for extensions, extra shifts and agreed adjustments.
• Retain off-hire acknowledgement, collection records and the final itemised invoice.
