Why your business could be paying too much for energy – and how to fix it

Energy costs can weigh heavily on any business, no matter its size or sector. Finding ways to lower those costs without disrupting operations is a priority for many. One solution worth considering is voltage optimisation (VO). It’s a practical way to reduce energy consumption, protect your equipment, and see financial returns relatively quickly.


What is voltage optimisation?

Voltage optimisation is a straightforward technology that adjusts the voltage supplied to your business. In the UK, the National Grid often delivers more power than needed – an average of 242 volts, while most equipment operates efficiently at around 220 volts. This excess can cause energy wastage, increase wear and tear on equipment, and lead to higher maintenance costs.


VO works by reducing the incoming voltage to a more efficient level. The result? Lower energy bills, less strain on your machinery, and fewer unexpected breakdowns. Although it might seem technical, it’s a practical choice for businesses looking to improve efficiency and keep costs in check.


Why a short payback period matters

One of the main advantages of voltage optimisation is how quickly the savings can cover the initial investment. Businesses that implement VO often see a return within one to three years, depending on their energy use. For operations with high electricity demands, the savings can add up even faster.


Let’s put this into context. Imagine your business spends £50,000 a year on energy. By reducing your energy use by around 6.5% (the typical reduction achieved through VO) you could save roughly £3,250 annually. In just a few years, those savings could cover the cost of installation, after which they become a boost to your bottom line.


Extending the life of your equipment

Voltage optimisation does more than cut costs. It also helps protect your equipment. Too much voltage can cause your machinery to overheat, wear out faster, or even break down. VO reduces this excess, helping your equipment run more efficiently and last longer.

For businesses, this means fewer repair costs and less downtime – both of which can be costly and disruptive. By keeping your equipment in better condition, you’re also getting more value from your investment in machinery or technology.


Supporting your sustainability goals

Beyond the financial benefits, voltage optimisation can help reduce your carbon footprint. By using less energy, your business can lower its emissions and contribute to wider sustainability efforts. As more companies aim to meet environmental targets, this added benefit can be an important step in aligning your operations with broader goals.

VO also offers a layer of protection against rising energy prices. By cutting consumption, you can reduce your reliance on fluctuating energy markets, providing greater stability in your operating costs.


Taking the next step

If you’re wondering whether voltage optimisation could work for your business, the first step is understanding your current energy use. That’s where our voltage tool comes in. This free tool lets you measure the voltage across different areas of your premises. Simply plug it into three different sockets, record the readings, and send the results to us for personalised advice.


Once your data is reviewed, you’ll get a clear picture of the potential savings and whether VO is the right fit for your business. There’s no pressure – just practical guidance to help you decide what works best for your needs.
