Our story
Less energy, simpler than you think
We built Kelvo because most households don't need an expensive smart install – they need a simple step that cuts consumption where it matters most.
Instead of calling an electrician or rewiring your home, you plug Kelvo between the socket and the appliance. No drilling, no permits. The result is measurable – with an energy meter you'll see the difference within days.
"We didn't want another gadget in a drawer. We wanted a cable anyone can use."

Where Kelvo helps most
The cable isn't magic – it makes the most sense on appliances that run at high power for longer periods.
Oven and cooktop
Ovens often run at high power for extended periods. The cable between socket and appliance helps optimize consumption while cooking.
Boiler and water heater
Heating water is one of the biggest loads in a home. Kelvo is a sensible add-on to your existing boiler.
Dryer and washing machine
For high-power appliances used frequently, a small optimization can mean a noticeably lower monthly bill.
Savings depend on appliance, usage and tariff. In test scenarios up to 50% lower consumption.
