Types of Voltage Optimisation Management
Fixed Voltage Optimisation
The system reduces voltage by a set percentage, such as 10%, regardless of any variations in the power being supplied. Fixed systems are cheaper to install and are best-suited for businesses with a consistent voltage supply.
Dynamic Voltage Optimisation
The dynamic system constantly monitors the voltage coming in to optimise the voltage out. It’s best suited for businesses with a variable voltage supply, such as those relying on renewable energy sources like solar or wind.
Combined Voltage Optimisation
The most advanced system available, combined voltage optimisation monitors incoming voltage to provide a smooth power supply while automatically lowering voltage to 220-230V.

Why Choose OKEL for Voltage Optimisation Management?

By working with OKEL, you can rest assured that our experienced team is dedicated to lowering your energy use, saving your business money, and reducing your emissions.
Our voltage optimisation management systems are a cost-effective solution to rising electricity bills, with government support available and a return on investment within a few years.
- Net-zero support: Lowering the voltage used across your business systematically reduces energy consumption, lowering emissions.
- Cost-saving: Operating your equipment with a lower voltage can extend its life span and reduce maintenance costs and downtime.
- Renewable energy integration: Some renewable energy sources, such as solar and wind, are intermittent energy sources. A voltage optimisation system levels out energy inputs to provide a consistent, stable output.
- Fast installation: Voltage optimisation systems are quick and easy to install, with smaller solutions only taking half a day to fit and set up.

Frequently Asked Questions
- How much does voltage optimisation management cost?
The price of a voltage optimisation management system will vary depending on several factors, in particular the type of system needed. Dynamic voltage optimisation is more expensive to install, but it can automatically adjust voltage, which could reduce energy bills further.
Many people report seeing returns on their investment within 2-3 years of installation.

- Can voltage optimisation management lower my energy bills?
Yes. Voltage optimisation management can lower your energy bills by reducing the incoming voltage powering your electrical appliances to the optimal level. As a result, some businesses see overall energy use fall by up to 20%.
- How long does it take to install voltage optimisation management?
The time it takes to install a voltage optimisation management system varies, but installation times can be as little as half a day.

- How frequently will my voltage optimisation management system require servicing?
It depends on the type of system installed at your business. A fixed voltage optimisation management system only requires servicing once every five years, whereas a dynamic voltage optimisation management system benefits from an annual check by a trained professional.
- Which industries would benefit the most from voltage optimisation management?
All sectors would benefit from a voltage optimisation management system due to its energy-saving capabilities. However, the most energy-intensive fields, such as data centres and heavy industrial processes, could significantly reduce their energy use and bills.
Hospitality businesses are also a top contender for a voltage optimisation management system. Many restaurants and bars are open long hours, with hotels operating 24/7, and a default high electrical load from equipment across the front and back of house. Voltage optimisation could instantly lower energy use and provide appliances with their optimal voltage, extending their lifespan.
Furthermore, public sector buildings are expected to lead the way in energy-efficient adaptations. Despite this, many have a considerable energy consumption baseline, which could be significantly reduced by voltage optimisation management.
- Is a voltage optimisation management system eligible for tax relief?
Yes, a voltage optimisation management system is eligible for tax relief through the UK Government’s capital allowances scheme. Business’s who invest in zero-carbon technology can sometimes deduct the full cost of the system from their profits before tax. Full terms and conditions are available here.
