Save Energy and Protect Essential Electrical Equipment

Your business could be experiencing rising energy costs due to electrical infrastructure and equipment diverting more power than it needs.

Voltage Optimisation adjusts incoming supply voltages by up to 20% to meet the exact demands of your systems.

Case Studies

Delivering an estimated 15% decrease in costs for Dental Excellence

The Challenges
Our Solution
Results

Dental Excellence, a leading cosmetic dental clinic in Liverpool, faced escalating operational costs due to high electricity consumption. Upon investigation, overvoltage was found to be causing frequent lighting component failures, which required regularly replacing and expensive dental equipment at risk.

OKEL installed a 100 Amp 3-Phase Wall Mounted Voltage Optimisation System, lowering the supply voltage from 251V to 224V. This was provided through our Green Funding Business Lease, a 60-month fixed-term agreement, and with monthly energy savings being offset against the fixed monthly lease payments.

  • Significant reduction in the frequency of lighting component failures, leading to lower maintenance costs.
  • An estimated 15% decrease in annual electricity bills
  • Reduced overvoltage stress on dental equipment
  • Showcasing sustainable business practices to patients and suppliers

Results

A leading timber merchant’s workshop, complete with high-powered machinery running daily, was experiencing voltage inconsistencies.

  • The company reported a drop in electricity bills, with savings in the range of 8%, amounting to annual savings of approximately £24,000.
  • There was a reduced risk of overvoltage damage, thereby extending the life of expensive CHC machinery motors and other workshop equipment.
  • More efficient energy use improved the company's environmental footprint 
  • Significant reduction in the frequency of lighting component failures, leading to lower maintenance costs.
  • An estimated 15% decrease in annual electricity bills
  • Reduced overvoltage stress on dental equipment
  • Showcasing sustainable business practices to patients and suppliers

How Much Could Voltage Optimisation Save You?

Voltage Optimisation can save businesses up to 19% on energy costs, but the exact savings will depend on your site.

Factors like your incoming voltage and the types of electrical equipment you use, whether they’re voltage dependent or independent, will affect how much you save.

A business with an electricity bill of £48,000 per year, who install a voltage optimisation system that generates savings in the region of 12%, would equate to electricity saving of around £5,760.00 per annum.

The higher your electricity bill, the more you save!

Save Energy, Cut Costs, and Protect Your Equipment

Our team has years of experience helping businesses improve their infrastructure, including energy management solutions such as voltage optimisation.

Voltage Optimisation is a smart way to manage your electricity use by adjusting the voltage that powers your equipment.

In the UK, the average voltage is around 242 volts, approx 10% higher than most appliances need. This excess voltage not only wastes energy and pushes up your electricity bills, but it also puts extra strain on your equipment, shortening its lifespan.

By reducing the incoming voltage to a more efficient Alevel, Voltage Optimisation helps your equipment run smoothly and use less energy.

The result? Lower energy bills, reduced carbon emissions, and less wear and tear on your appliances—a win for your business and the planet.

How Much Does Voltage Optimisation Cost?

The cost of a voltage optimisation system depends on your site’s power needs and the specific setup of your business. Every location is different, so prices can vary. 

Many businesses prefer to lease their voltage optimisation system through OKEL’s Green Funding Business Lease.

This lets you spread the cost with fixed monthly payments, making it easier to manage your budget.

Plus, the energy savings from the system often cover or exceed the lease payments, so you save money from day one without a big upfront investment.

Whether you choose leasing or self-funding, we’ll help find the best option for your business.

Why Voltage Varies and Why It Matters

Mains electricity has never been the same everywhere; it naturally varies. Before 1993, the UK standard was 240V with a small margin for change. But in reality, much of the UK was already getting closer to 220V.

To bring things in line across Europe, new rules (called the Low Voltage Directive) were introduced. As a result, the UK changed its official supply level to 230V, with an allowed range between 216V and 253V.

However, many older parts of the UK’s power grid still operate using the old standards, which means some places regularly get higher voltage than needed. This is called overvoltage, and it can lead to wasted energy and extra wear/breakdowns on your equipment.

How Voltage Optimisation Supports Renewable Energy

Renewable sources like solar and wind produce power that can vary with the weather conditions, causing voltage swings that affect grid stability.

Voltage Optimisation keeps voltage levels steady, helping the grid handle these fluctuations more smoothly.

It also maximises efficiency, renewable systems like solar panels and wind turbines work best at stable voltages.

By reducing energy loss and ensuring equipment runs at its optimal level, voltage optimisation helps make the most of every unit of clean energy generated.
