Why choose Powerdown220 for your voltage optimiser?


    As the UK’s leading voltage optimisation specialist, we are the experts when it comes to this technology. While other companies might focus on many different technologies, we channel all our expertise into voltage optimisation, ensuring you are getting the best technology for your needs.


    As a company, we are united by a vision of being the best at what we do. This means working closely with you to identify what you need for your business. We won’t sell a product you don’t need, even if you originally ask for it. We also offer bespoke products to match your requirements. Our goal is to save you money. 


    We only use installers who are trained specifically for voltage optimisation, to make sure this crucial phase of the process is done right. We work with Ashcrofts, who are part of the Powerdown family. In contrast to your average installers, they have a VO-qualified team of electricians who are experienced in onsite installation.


    We have worked with some of the biggest brands in the country and on some of the biggest voltage optimisation projects, including the largest voltage optimisation project ever delivered in the UK. Choosing Powerdown220 means you are working with a company that consistently delivers the same quality products and services every time.

What can I save with a voltage optimiser?

Supply from the national grid in the UK averages around 242 volts, but optimal performance for most electrical equipment is achieved at 220 volts. Running additional voltage through your equipment is wasted energy. This is costing your business money even shortening the lifespan of your equipment.

By installing a voltage optimiser, you lower the voltage to the required level. This ensures you only pay for the voltage you need, not what you receive from the grid. It’s that simple. The result is a lower electricity bill. On average, the simple installation of voltage optimisation will usually save between eight and twelve per cent, but potentially more depending on your site.

By partnering with you to help reduce your energy costs, we also help you reach your sustainability goals. Power down to 220 with us and you can do your bit on the road to net zero.
