Temporary Fuel Surcharge
As I’m sure you’re aware military action in Iran has closed the Strait of Hormuz, putting pressure on global fuel supply and costs. This has resulted in significant increases to the cost of fuel. Whilst we have worked hard to absorb these costs, to ensure we can continue to deliver a high level of service and continuity of supply we will be introducing a temporary fuel surcharge, effective 23rd March 2026.
* The temporary surcharge will cover a portion of the additional fuel related costs, as they are passed on to us by our suppliers.
* The fuel surcharge will be applied as a separate line on invoices.
* The surcharge is variable and may increase or decrease over time, in line with movements in the price of fuel. We’ll be using the National retail diesel price.
* We will be reviewing these temporary surcharges regularly to try and reduce the impact to you as much as possible.
This approach allows us to respond to external fuel cost movements in a measured and transparent way, without the need for frequent changes to base rates, while continuing to provide the level of service and reliability you expect from Winstone Aggregates.
Fuel Surcharge as at 31st March 2026
Based on the current diesel pump price, our fuel surcharge from the 31st will be an additional 8.7% on invoice total.
The below table gives you an idea of how the surcharge will work based on National diesel pump pricing, to allow you to plan as best as possible whilst we navigate this situation. You can also refer to the gaspy website for the latest retail price of diesel at https://www.gaspy.nz/stats.html
