Our Process

Saving money and becoming more efficient with Powerdown220 is simple. We complete 4 steps to ensure maximum energy savings – that are based on scientific principles and 30+ years of experience working on energy efficiency projects

Survey

What we need

Half-hourly consumption data – from this, we can work out your annual energy usage and spend based on your half-hourly consumption and maximum demand.
Monthly energy bill – with the bill, we can work out your blended kWh rate which matched with the half-hourly data, gives us your exact energy spend for the year.
Initial proposal: We give you savings figures based on your annual consumption and industry sector.
Voltage Dependency survey: Our technical team will analyse the equipment our clients have on-site and categorise each piece of equipment in our voltage dependency survey; giving savings projections based on where we will and won’t make savings across a site.

Installation

Our dedicated team of nationwide installers will establish the where the equipment can be installed and work out the most cost-efficient installation for all of our customers. Once our survey is complete we deliver our final proposal and savings guarantee.
Once we book an installation date our team of expert installers will be on-site to complete any prep work, arrange site-shutdowns and connect the machines.
Some installations may have extra requirements. Whether that be knocking through walls, outdoor covers, concrete bases, or building the machine in 3 separate phases, we have seen it all!

The Benefits of a Powerdown220 Installation:

REDUCED
ELECTRICITY BILLS

Voltage optimisation reduces energy use, cutting bills. Powerdown220 customers save 7 12% on electricity costs typically.

EXTENDED
EQUIPMENT LIFESPAN

UK Wiring Regs (BS7671) caution high voltage impacts equipment lifespan. Voltage optimisation prevents damage, extends longevity, and reduces costs.

LOWER CARBON
EMISSIONS

Voltage optimisation reduces electricity consumption, aiding in carbon emission reduction, supporting sustainability goals and environmental responsibilities.

ENHANCED RETURN ON INVESTMENT (ROI)

Voltage optimisation investment yields rapid, significant ROI, with savings offsetting initial costs, ensuring enduring financial gains.

GENERATE YOUR OWN POWER

With our Solar PV solutions, our clients can generate their own electricity, reducing their energy costs, and carbon emissions while minimizing reliance from fossil fuels

Projects

Mitchells & Butlers Achieve UK's Largest

Voltage Optimisation Rollout

Mitchells and Butlers have cut costs and carbon in the largest UK VO rollout in history. With a target of achieving net zero emissions for the company by 2040, Voltage Optimisation became the technology of choice to help towards this goal.

WHAT IS VOLTAGE OPTIMISATION?

Supplying your site with the energy it needs, not what it's given.

The average voltage supply from the UK National Grid is 242 volts, but all CE marked appliances and equipment operate best at 220 volts. With voltage optimisation, you lower the level of voltage to match your needs. By paying for what you need, not what you get, you will quickly discover significant savings on your energy bills.
