Voltage Optimisation
Reduce energy consumption across all electrical equipment
Optimise your voltage supply to reduce energy waste and extend equipment life across your entire facility.
Reduce energy waste,
improve equipment life, and lower running costs
We help you save energy, reduce operational costs, and extend the life of electrical equipment. We guide you through the process from assessment to installation and ongoing performance checks, so you get measurable results without the usual uncertainty.
Business case for voltage optimisation
Why voltage optimisation matters
A lot of industrial and commercial buildings run on higher voltage than necessary, which often results in:
Electricity wasted powering equipment at higher-than-needed voltage.
Motors, pumps, and lighting systems degrade faster under excess voltage.
Increased downtime, maintenance costs, and reduced system reliability.
Unnecessary energy use increases your environmental footprint.
Save energy, extend equipment life, and improve reliability
Voltage optimisation reduces incoming voltage to the optimum level for your equipment.
It ensures your equipment:
- Operates efficiently without loss of performance
- Lasts longer and requires less maintenance
- Uses less energy and reduces carbon emissions
When a voltage optimisation system is fitted, most sites cut energy use by around 5 to 15%. Businesses see equipment last longer and lower operating costs – all without any loss in safety or performance.
Even if you’re new to voltage optimisation, we’ll provide guidance on whether it’s suitable for your site, what the payback period might be, and the practical steps to implement it safely.
Did you know?
The National Grid delivers, on average, 242 volts to all UK users. With voltage optimised, electrical
equipment works at optimum cost efficiency at 220 volts. All supply above 220V is a waste. Through
Ohm’s law, optimising voltage on any supply, produces instant kWh savings of up to 20%, which will
give an instant reduction in electricity bills and carbon footprint. In addition, and as confirmed by the
UK’s wiring regulations (BS7671), any electrical equipment required to work at 242v, will suffer a
reduced working life by up to 46%.

FAQs
Voltage optimisation is a solution that reduces incoming electricity voltage to the optimal level for your equipment. It reduces energy waste, lowers bills, and extends equipment life without affecting performance.
Savings vary by site, but most industrial facilities see a 5–15% reduction in energy use for equipment affected by overvoltage. Savings depend on equipment type, usage patterns, and supply conditions.
No. VO systems are designed to supply electricity at optimal voltage, ensuring your equipment runs safely and reliably. Motors, pumps, lighting, and other devices operate normally – just more efficiently.
Most industrial and commercial sites can benefit, especially those with:
- Extensive lighting systems
- Equipment with extended operating hours
We’ll assess your site to determine if VO is a practical and cost-effective solution for you.
Installation will typically take 1 – 3 days, depending on your site’s size and complexity. Our VO partner manages the process to ensure minimal disruption to your operations.
Yes. VO systems comply with UK electrical standards, are installed by qualified engineers, and include full testing and verification. We also provide documentation for audit and compliance purposes.
Most sites see a return on investment within 1-3 years, depending on energy usage, tariffs, and system size. Long-term benefits include lower energy costs, reduced maintenance, and extended equipment life.
VO devices are generally low-maintenance, but we offer monitoring and performance checks to ensure your system continues delivering energy savings over time.
