Reach Your Cost-Saving & Sustainability Goals with Voltage Optimisation…
In the current landscape of escalating energy costs and environmental awareness, businesses are seeking effective strategies to manage electricity expenses and reduce their carbon footprint. Powerhub Solutions offers voltage optimisation technology that addresses these challenges by ensuring your equipment operates at optimal voltage levels, leading to significant energy and cost savings.
What Is Voltage Optimisation?
Voltage Optimisation (VO) is a proven energy-saving technology that reduces the excess voltage supplied to electrical equipment, improving efficiency and cutting energy waste.
Most electrical equipment is designed to operate within a range of mains voltages, but in many cases, the actual supply voltage is higher than necessary. This leads to overpowering, generating unwanted heat, and shortening equipment lifespan.
Where are the Savings Made?
Voltage Optimisation reduces energy consumption, lowers costs, and extends equipment lifespan by ensuring devices operate at their optimal voltage, primarily achieving savings through kWh reduction.
Reduced kw/h consumption
Reduced Maintenance Costs
Voltage Optimisation in 4 simple steps
At Powerhub Solutions, we make cutting energy waste simple and stress-free. Our Voltage Optimisation technology helps you reduce costs, improve efficiency, and protect your equipment—with zero hassle. Our four-step process ensures you get maximum savings with minimum disruption.
1. Discovery
Find out what you could save
Think you might be overpaying on energy? We analyse your energy data to estimate your potential savings. All we need are three simple pieces of information from your energy supplier—send them via our online form, and we’ll show you exactly how much you could save and the return on investment upfront.


2. Site Survey
Confirming before you commit
If you’re happy with the estimated savings and want to move forward, the next step is a detailed site survey. Our team will visit your premises to verify the projected savings, assess installation requirements, and confirm the final installation cost. If Voltage Optimisation isn’t the right fit for your business, we’ll be upfront about it and suggest other energy-saving solutions.
3. Installation
Quick, hassle-free, and done right
We know your business can’t afford downtime, so our expert engineers handle everything smoothly, working outside business hours to keep disruption to a minimum. The final switch-over? Just two to four hours, and you’re up and running!

4. Monitor & Verify
Savings you can see, whenever you want
After installation, you’ll receive monthly reports showing exactly how much you’re saving. Plus, with access to our real-time monitoring platform, you can track your energy savings anytime, anywhere.
