Cutting carbon through voltage precision

Real energy efficiency starts by giving your equipment exactly what it needs. While the National Grid often delivers power at a higher voltage than necessary, most business infrastructure is designed to run optimally at 220V.

Immediate Cost Reduction

Achieve up to 19% reduction in electricity spend and up to 9% savings on overall energy consumption through precise voltage alignment.

Minimal Operational Disruption

Voltage optimisation is a low-maintenance technology that can be installed quickly with little to no impact on your daily operations.

Enhanced Equipment Lifespan

By delivering power at the optimum level, you reduce heat stress and vibration in your machinery, significantly extending its working life.

Stop paying for voltage you don't need

Your supply arrives higher than it needs to

The UK supply is declared at 230V and can legally run to 253V. Many sites sit well above 230V.

The unit brings it back down

Fitted between your meter and distribution board, it trims the voltage to the level your equipment needs.

Your equipment uses less energy

Motors, lighting and other voltage-sensitive loads draw less for the same work. We log your supply first and model the saving before you commit.

It runs cooler and lasts longer

Less over-voltage means less heat and stress in motors, drives and light fittings.

Proven on real sites

At Deliveroo, a voltage optimisation roll-out saves £92k a year and has cut 87,444 kg of carbon emissions.

At Fidelity Energy, we use 20 years of expertise to bridge that gap. Through voltage optimisation, we stabilise your power supply to match your equipment’s requirements. This doesn't just lower your energy spend; it protects your machinery and slashes your carbon footprint.

We manage nearly £1bn in energy spend, giving us the scale and data to look beyond the meter. We turn your power supply from a passive cost into a high-performance asset. By removing the hidden waste in your electrical system, we make the transition to Net Zero both simple and profitable.

Our strategic oversight ensures your journey to sustainability isn't just a box-ticking exercise, it’s a permanent upgrade to your business’s efficiency.

Assess your energy usage

We review your electricity consumption and site requirements to determine if voltage optimisation can improve efficiency and reduce costs.

Identify the right solution

We identify the most suitable system to help reduce energy waste, lower costs, and improve performance.

Install with minimal disruption

We manage the full process, from assessment to installation, ensuring a smooth transition with minimal impact on your operations.

Streamline your data
with Etainabl
