What is UK Voltage Optimisation?
UK voltage optimisation is a technology designed to manage and reduce the incoming voltage from the National Grid. While appliances are typically rated for 220-230 V, the UK’s average supply is closer to 242 V. This higher voltage can lead to energy waste and shortened equipment lifespan. Voltage optimisation systems work by regulating this supply down to more efficient levels without impacting performance.
There are two main types of systems:
- Fixed voltage optimisation – this reduces voltage to a set level, ideal for sites with stable voltage profiles.
- Dynamic voltage optimisation – this continuously adjusts voltage in real-time based on fluctuations, best suited for sites with varying loads or inconsistent supply.
Why Commercial Voltage Optimisation Matters
In the UK, average mains electricity supply voltage often exceeds 240 V – well above the nominal 230 V required by most equipment. This excess voltage leads to energy waste, unnecessary wear on equipment, and inflated carbon emissions. By installing a commercial voltage optimisation system, your business can:
- Reduce energy consumption by up to 10-15%
- Lower your carbon footprint and meet net-zero targets
- Protect electrical equipment for voltage stress
- Improve power quality and reduce downtime caused by electrical inconsistencies
Benefits of Commercial Voltage Optimisation
Cut energy consumption by 15%
By reducing excess voltage, your business can cut avoidable energy usage, often achieving double-digit savings on electricity bills without changing equipment or operations.
Extend Equipment Lifespan
Excess voltage places strain on machinery, lighting, HVAC systems, and more. Optimisation helps reduce wear and tear, extending the life of assets and reducing repair costs.
Improve Electrical Reliability
Voltage optimisation stabilises supply, reducing issues like power spikes, dips, or harmonics that can cause failures or downtime.
Support Sustainability Goals
Lower energy consumption directly translates to fewer emissions, helping you hit internal ESG targets and comply with environmental regulations.
Achieve Faster ROI
By optimising your incoming supply, you improve overall system efficiency and speed up the ROI across your wider energy strategy.
How Our Commercial Voltage Optimisation Service Works
We offer a streamlined process, tailored to the needs of your site and operational profile. Our process consists of:
Site survey and voltage assessment
we’ll analyse your incoming voltage and load profile to determine your optimisation potential and suitability.
System design and recommendation
based on your specific voltage levels (especially those exceeding 230 V), we’ll design a fixed or dynamic solution for maximum efficiency.
Professional installation and commissioning
our engineers will install your voltage optimiser with minimal disruption to operations, ensuring all systems are correctly integrated and tested.
Ongoing monitoring and minimal maintenance
once installed, our voltage optimisation systems typically require little to no ongoing maintenance, and we can add optional monitoring for performance tracking and reporting.

Commercial Voltage Optimisation FAQs
It’s a system that reduces and regulates the incoming electrical voltage to levels better suited to your equipment, improving efficiency and reducing waste.
The UK’s grid often supplies higher-than-needed voltage (averaging ~242 V), which wastes energy and strains equipment. Optimisation brings voltage down to more efficient levels, saving money and improving performance.
Typical savings are usually up to 10-15% on electricity bills, depending on your site’s current voltage and energy profile.
Any business with high energy usage or sensitive electrical equipment – such as manufacturers, offices, hospitality venues, and retail spaces – can benefit.
No, in fact, it improves performance consistency by eliminating overvoltage, which can cause overheating and wear.
After a site survey and voltage assessment, we design and install a bespoke system, ensuring minimal disruption and full commissioning.
Depending on varying factors, typically, many businesses achieve payback within 2 to 4 years, with ongoing savings continuing for the system’s lifespan, which is usually 15-20 years.
Not always. That’s why we’ll carry out an assessment to ensure your site’s voltage profile and energy usage to determine if your property is suitable.
