The Problem: Excess Voltage
The UK electricity grid supplies voltage at a nominal 230V, but in practice many sites receive 240V or higher. Most electrical equipment is designed to operate optimally at 220V. That excess voltage doesn't improve performance. It simply converts to waste heat, increasing energy consumption and accelerating equipment wear.
How Voltage Optimisation Works
A voltage optimisation unit is installed between the grid supply and your distribution board. It steps down the incoming voltage to the optimal level for your equipment. The technology is entirely passive once installed. There are no moving parts, no ongoing maintenance, and no disruption to your operations. Installation typically takes less than a day.
Which Equipment Benefits Most?
The biggest gains come from inductive loads: motors, compressors, fans, pumps, and lighting. If your site runs a significant amount of this type of equipment, voltage optimisation delivers substantial savings. Manufacturing, cold storage, retail, and hospitality sites tend to see the strongest returns. Modern IT equipment and variable speed drives already regulate their own input voltage, so they see less benefit.
Measurable, Guaranteed Savings
We install monitoring equipment before and after implementation to verify actual savings. There's no guesswork involved. You'll see exactly how much your consumption drops, typically within the first billing cycle. Many of our installations come with performance guarantees, giving you confidence in the business case from day one.
Financial Case
With typical savings of 6-12%, most installations pay back within 3-4 years. After payback, the savings continue for the 20+ year lifespan of the unit. There are also enhanced capital allowances available, meaning you can offset the full cost against taxable profits in the year of purchase.
