For most drivers, yes. A smart EV charger connects to an app and schedules your charging for the cheapest off-peak hours, which can mean paying around 7p a unit overnight instead of the full daytime rate. It also balances load so it does not overwhelm your supply. The savings usually outweigh the small extra cost over a basic charger.
What does “smart” actually mean on an EV charger?
It is worth being clear, because the word gets thrown around. A smart EV charger is one that talks to an app on your phone and can make decisions about when and how fast to charge, rather than just dumping power the moment you plug in. In practice “smart” on a charger means things like:
- Scheduling charging to run during cheap, off-peak hours automatically.
- App control and monitoring, so you can start, stop, check progress and see your usage from your phone.
- Load balancing, so the charger eases back if the rest of the house is drawing heavily, protecting your supply.
- Tariff integration, where the charger links to your energy plan and charges when power is cheapest and often greenest.
One thing to be clear about, this is about charging your car cleverly, not about controlling your house. A smart EV charger is not home automation and does not turn your home into a smart home, it is a single appliance that happens to be good at timing itself. Snelling Electrical fits smart EV chargers, and does not do home automation, so the focus here is purely on getting your car charged as cheaply and safely as possible.
How do smart chargers save money on cheap overnight rates?
This is the headline reason people choose smart. Most energy suppliers now offer EV-friendly tariffs with a cheap overnight window, where electricity can drop to roughly 7p per unit for a few hours in the small hours, against something like 25p to 30p at standard rate. A smart charger lets you set a schedule, or links straight to the tariff, so the car charges during that cheap window without you setting an alarm or remembering to plug-and-unplug at odd hours. You plug in after work, walk away, and the charger waits until the rate drops, then fills the car up overnight. Over a year of regular charging, the gap between the cheap rate and the standard rate is where the real saving sits, and it is what makes a smart charger pay for itself.
What is load balancing and why does it matter?
Load balancing is the quietly important feature. Your home has a limited supply, and a 7kW charger is a serious draw, roughly the same as running an electric shower continuously. If the oven, the shower and the charger all pull hard at once, you risk overloading the supply. A smart charger with load balancing watches the demand on the property and automatically dials its own power down when the rest of the house is busy, then ramps back up when there is headroom. It means you get the fastest safe charge without nuisance trips, and it can be the difference between needing supply work and not. Whether your supply and board can take a charger at all is worth reading in home EV charger cost, because we check that before fitting anything.
Which smart EV charger brands are worth looking at?
The main smart chargers Jack fits each lean slightly different ways:
- Ohme is the standout for tariff-led charging, with deep integration that automatically charges when electricity is cheapest, ideal if your priority is squeezing the off-peak rate.
- Hypervolt is the design-led choice, a good-looking unit with a polished app and capable scheduling and load management.
- Zappi (myenergi) is the one to consider if you have solar, as it can charge from surplus generation, though its smart scheduling works well regardless.
There is no single “best”, only the right one for your car, your tariff and how you like to use it. We compare them in full in EV charger brands compared, and Jack recommends based on your setup, not on margin.
Are smart chargers worth the extra cost?
For most people, yes. A smart charger costs a little more than a bare-bones unit, but the saving from reliably charging on a cheap overnight tariff typically outweighs that difference, often within the first year or two of regular charging, and you keep saving after that. You also get the convenience of app control and the protection of load balancing. The case is weaker only if you barely drive, cannot get an off-peak tariff, or charge mostly in the day at standard rate, and even then the load-balancing and monitoring have value. For a normal household charging overnight, smart is the sensible default, which is why nearly every charger we fit is a smart one.
Does it need a special installation?
The installation is the same careful job as any charger, by a qualified electrician, certified and notified, with the supply and fuse board checked first. The smart features are built into the unit and set up through its app once it is fitted, the charger pairs to your wi-fi and tariff during commissioning. Snelling Electrical fits smart EV chargers from £900 fully installed, with the survey, fitting and certification included, and gives you a written quote within 24 hours. You can see what is involved on the EV charger installation page.
