Yes. Our team can review your current products, usage and cleaning processes to identify opportunities to reduce your cost-per-use, minimise over-dosing and product waste, and improve efficiency.Our high-concentration chemical systems can help reduce the volume of product required, while dispensing systems can provide consistent dilution and help prevent costly over-pouring. We can also review your current product range and recommend alternatives where they offer better value for your business.

The process is simple, completely hands-off for you, and takes just three steps:Provide Your Usage Details: Send us a quick itemised list, a photo of the chemicals currently on your shelves, or a recent invoice—whichever is easiest for you.On-Site Facility Assessment: We will visit your venue to assess your specific operational setup and recommend suitable products and dispensing hardware to suit your business requirements.We Do The Math: Our team maps your current setup against our high-concentration formulas. We calculate your current and potential cost-per-dose and deliver a transparent comparison showing your projected budget savings & identify opportunities to improve chemical handling and prepare for the new WEL framework.The audit is completely free with no obligation. Our goal is simply to show you where you may be able to reduce costs, improve chemical handling and make your cleaning system more efficient.

No, it is not mandatory. Even when diluted manually, our highly concentrated, commercial-grade formulas still deliver exceptional value and drastically lower your ongoing cost-per-dose. However, adding an automated dispensing system is highly recommended because it reduces staff guesswork, stops costly over-pouring, and keeps concentrated chemicals enclosed during dispensing, reducing direct handling.

Yes. From 1 December 2026, new Workplace Exposure Limits (WELs) will apply to a range of airborne hazardous substances. Businesses that use or handle chemicals need to consider how workers may be exposed and what controls are appropriate for their workplace.The changes are particularly relevant for businesses that regularly handle or mix concentrated chemicals.Download our Free Chemical Compliance Pack to understand the changes and review your current chemical practices ahead of the December 2026 transition.

Enclosed dispensing systems reduce the need for staff to manually handle, decant and pour concentrated chemicals. Controlled dispensing also helps provide consistent dilution and reduce over-pouring and spills.By reducing direct handling of concentrated products, dispensing systems can support safer chemical handling practices as businesses review their controls ahead of the 2026 WEL changes.A dispensing system is one part of a broader WHS approach and does not by itself make a workplace compliant.

No. While our team carries out assessments and provides professional product and hardware recommendations to support your safety goals, the ultimate legal responsibility for workplace compliance rests entirely with your business. It is your responsibility to know your industry's specific regulatory requirements, ensure your staff are properly trained, and correctly apply the necessary safety measures on-site.
