Why consider Voltage Optimisation?

  • Reduces energy bills around 10%
  • Quick, simple installation between the meter & consumer unit (fuse board)
  • No maintenance or service requirements
  • Prolongs the lifespan of equipment & appliances
  • Reduces carbon emissions and the impact on the environment
  • Improves efficiency of PV systems, heat pumps & wind power
  • Payback within 5 years
  • Guaranteed energy & money savings
  • Minimum 5 year warranty
  • Expected lifespan 20 years


How does Voltage Optimisation work?

Voltage Optimisation works to reduce and stabilise the incoming voltage to a property and so reduce the amount of electricity used. A typical supply is allowed to be between 207V and 253V, the UK average is around 242V. Most electrical appliances are designed to work around 230V (with a tolerance of +10% or -14%). So by dropping the voltage to 220V-225V appliances will still work but use less power, saving money and reducing carbon emissions. The other plus is that many appliances will benefit from the lower voltage by extending their working life. Some electrical circuits and appliances such as electric heaters or ovens don’t benefit from this reduced voltage and may be compromised if they are connected to the voltage optimiser so it’s important to get expert advice.

Frequently Asked Questions

Does it really matter that the voltage is high?

The higher the voltage the higher the energy consumption. By installing a voltage optimisation unit the average home can save around 10% per year on their electricity bill. In addition, by reducing the incoming voltage to your property, you can also prolong the lifespan of your electrical equipment and appliances.

What is the life expectancy of a voltage optimisation unit?

All of our voltage optimisation units come with a minimum 5 year warranty and expected lifespan of 20 years. There are no maintenance or service requirements.

How long will it take to install the optimiser?

This is very much dependant on the task at hand. Prior to the work taking place we will do a site survey and talk you through what is required and how long the job is likely to take. As a general guide, it will normally take a few hours.

Will electricity need to be turned off during the install?

There will be a short period of downtime required however we will complete all preparation work before power is turned off to reduce the amount of time you are without power.

Do I need to inform my energy supplier?

No, there is no need to inform your electricity provider.


“We are extremely pleased with the work Norcroft have undertaken for us – it was trouble-free and completed to a high standard and nothing has been too much trouble for them. I would have no hesitation in recommending Norcroft Energy to anyone considering this step.”

Mr & Mrs Scott, Homeowner, Sheffield

“Norcroft Energy came to advise us at our request and the advice given was first rate. The work was recommended by Norcroft Energy as an energy saving means. They installed 23 LED 5 watt lamps and a voltage optimisation system. The club saved £847 on electricity bills in the first year.”
