Do Water Softeners Run on Electricity?

Thinking about soft water but worried your softener might spike your bill like a rogue kettle? Short answer: Yes, most water softeners do use electricity — but only a small amount! From smart tech to non-electric models, we’ll break down what this means for your electricity bill, maintenance and performance, and overall efficiency.

The Power Source of Water Softeners

Most people don’t think about what powers their water softener — until the bill arrives or the unit stops working. Whether or not it uses electricity depends on the model sitting under your sink or in the garage.

Some Water Softeners Use Electricity

Electric water softeners are the most common type found in UK homes. But before you imagine your softener gobbling up kilowatts like a tumble dryer, relax — their power use is incredibly modest.

For the Control Valve's Operation (Regeneration)

Electric softeners need a bit of juice to power the control valve. This valve is the bit that tells the softener when to regenerate — basically when to clean itself out and get ready to tackle more hard water. It’s not much power, usually around 30 to 50 watts during that short cycle. That’s less than most light bulbs! Think of it as the brain of the machine — clever enough to save salt and water while keeping things running smoothly.

For Advanced Features

If you’ve got a swanky model with a touchscreen, app notifications, or Wi-Fi, those bells and whistles also need electricity. These smart features don’t just look fancy — they let you control settings remotely, monitor salt levels, and even schedule regeneration for off-peak hours when electricity is cheaper. It’s like giving your plumbing a tech upgrade, without blowing the fuse box.

Non-Electric Water Softeners Exist

Not all water softeners need plugging in. In fact, some of the most reliable ones work purely off water pressure.

Powered by Water Pressure

Non-electric softeners use clever mechanical valves instead of electric timers. As water flows through your pipes, it drives the regeneration cycle automatically. They’re perfect for people who want fewer moving parts, less maintenance, and a lower carbon footprint. No plugs, no programming, no fuss. These systems are also ideal for countryside homes or off-grid living, where power cuts are more than just an occasional annoyance.

Identifying if Your Water Softener Uses Electricity

So how can you tell if yours runs on electricity? It’s easy: if it’s got a plug or a digital display, it’s electric. No plug, no lights? You’ve likely got a non-electric system. Still unsure? Look up the model number online or check the manual.

Do Water Softeners Need Servicing?
Yes — but don’t panic. Servicing usually involves a quick salt top-up, brine tank clean, and a once-over on the valves. An annual check-up helps your system run efficiently and keeps your warranty valid. Like a car MOT, but for your water.

Conclusion: It Depends on the Type of Softener

So, back to the original question: do water softeners run on electricity? Some do, and some don’t. It all comes down to the type you choose. Electric softeners offer more automation and flexibility, especially if you love your tech. Non-electric softeners keep things simple and stress-free — ideal if you prefer the “fit and forget” approach. Whichever route you go, the end result is the same: softer water, longer-lasting appliances, and fewer limescale dramas. It’s all about choosing the one that suits your lifestyle, your home — and your power bill.
