Voltage Optimisation
Built in the UK for Zero Downtime
The voltage optimiser you never have to switch off.
SavaPower lowers your building’s electricity bill with realistic, surveyed savings — and a fail-safe automatic bypass that lets us adjust, service or bypass the unit without ever shutting down your building. Built and supported directly by the manufacturer.
The SavaPower difference · Peace of mind, built in
Adjust, service or bypass — without shutting down your building.
Most voltage optimisers have no bypass. To adjust the voltage, service the unit, or take it offline, the entire building has to be powered down. SavaPower’s automatic bypass is fitted as standard — so we can do all three live, with zero downtime and no lost trade. You’re buying peace of mind, not a quick fix that becomes tomorrow’s problem.
Adjust anytime
Zero Downtime
SavaPower engineers can change your site's voltage tapping WITHOUT SHUTTING DOWN YOUR BUILDING so there no disruption to trading.
Upgrading your site?
POPULARVO that grows with you
Adding electric cookers or new load later? We simply swap the transformer part — with zero downtime to the building. Your system grows with you.
The competitor risk
Why buy a SavaPOWER
Overload a unit with no bypass and it can trip — plunging your site into a blackout and costing you a day's trade. SavaPower simply bypasses and keeps you running.
A commercial voltage optimiser manufacturer — not a reseller.
SavaPower units are designed, built, tested and commissioned in-house in Britain. When you buy from SavaWatt you buy direct from the manufacturer — cutting out the distributor and the middleman markup that inflates the cost of most voltage optimisation projects.
As UK energy-saving specialists since 1985 and a Made in UK member, we control every stage — so you get factory pricing, faster lead times, and a direct line to the engineers who actually built your system.
Design & build
Transformers, control boards and enclosures assembled and tested in our own facility.
Factory pricing
No distributor markup means a better ROI and a shorter payback period on every install.
Direct support
Talk to the people who engineered your unit — not a third-party support desk.
HOW IT WORKS
Optimised voltage in, lower bills out.
SavaPower sits between your incoming supply and your distribution board, using a multi-tap transformer to bring site voltage down to the optimal level — with automatic bypass protecting your supply at all times.

Commercial voltage optimisation, answered.
Voltage optimisation reduces the excess voltage supplied to your building down to the level your equipment actually needs. Because higher voltage means higher consumption, trimming it lowers energy use, cuts your bill and reduces carbon — with no change to how your site operates.
Typical commercial sites save around 8–12% on their building electricity bill, depending on how high their supply voltage sits. We deliberately quote realistic, surveyed figures rather than headline numbers — and our built-in energy monitoring proves your actual saving in real-time, measured to the kWh, so you see the return rather than a promise.
Buying a voltage optimiser through a distributor or installer adds a middleman markup and puts a third-party support desk between you and the product. SavaWatt designs and builds SavaPower in-house in the UK, so you get factory pricing, a better ROI, and a direct line to the engineers who built your unit.
Every SavaPower includes an automatic bypass as standard. If a fault is detected, the unit seamlessly bypasses itself and returns your site to full mains voltage — so your facility never loses power. An automatic low-voltage cut-out provides the same protection during a brownout.
Yes. Installation is fully managed from survey to switch-on by our own NICEIC and ECA-approved electrical teams, supported by a trusted network of authorised UK partners for nationwide coverage.
