Benefits
THE BENEFITS OF WORKING WITH POWERDOWN220
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.
SOLAR POWER GENERATION
Solar power generation offers a rapid and substantial return on investment, with energy savings quickly outweighing initial costs and providing lasting financial gains.
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.

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.

TRACK AND GURANTEE
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.
Manufacture
At Powerdown220, all our products are proudly manufactured in the UK to the highest standards, meeting strict ISO certifications and carrying the Made in Britain mark. Each machine is custom-built to suit individual client requirements, ensuring a truly bespoke solution every time.
We combine precision with innovative features and competitive lead times to deliver industry-leading products. Our manufacturing capabilities cover our full range of advanced Voltage Optimisers and Voltage Stabilisers, designed for performance, reliability, and long-term energy savings.
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!!

EXTENDED EQUIPMENT LIFESPAN
Running additional voltage through your equipment is damaging. As well as lowering your carbon emissions, voltage optimisation can help prolong the life of your equipment by up to 46%.
Voltage Optimisation significantly extends the lifespan of your equipment. Excess voltage can cause overheating and excessive wear and tear, leading to premature failure, as stated by UK wiring regulations (BS7671).
Optimising voltage levels protects your devices from these damaging effects, ensuring they last longer and perform more reliably.
REDUCE YOUR CARBON EMISSIONS
Voltage optimisation doesn’t just reduce your energy bills, it reduces your carbon footprint too. We are proud to be experts in a technology that will be key on the road to net zero.
By optimizing voltage levels, we help ensure that energy is used more efficiently and sustainably across the board. This means reducing unnecessary energy waste, lowering electricity consumption, and minimising the strain on the electrical grid.
GUARANTEED ENERGY SAVINGS
With 30+ years of voltage optimisation and electrical engineering experience, we are able to offer a unique Savings Guarantee to all of our customers.
Once we have undertaken a full site survey, there is no guessing or speculating about what your savings will be, Powerdown220 will guarantee them.
If we don’t achieve the savings promised in our proposal, we will remove the optimiser and offer a full refund.
