When you start shopping for a home EV charger, you'll quickly notice that some are described as "smart" and others aren't. Smart chargers typically cost more — so do you actually need one? Short answer: for most people, yes. Here's why. ## What Is a Smart EV Charger? A smart EV charger connects to your home Wi-Fi and can be controlled via a smartphone app. But beyond the basics, the best smart chargers can: - **Schedule charging** for off-peak electricity hours - **Integrate with your energy tariff** to charge automatically when electricity is cheapest - **Monitor your energy usage** and show you exactly how much each charge costs - **Integrate with solar panels** to prioritise free solar energy - **Communicate with your energy provider** for dynamic pricing - **Enable load balancing** so your home doesn't trip the fuse when charging ## The Money Argument: Why Smart Chargers Pay for Themselves This is the real reason to care about smart charging. If you're on a standard electricity tariff, you're probably paying around **24–28p per kWh** for electricity. That makes charging a typical EV from empty cost around £12–£16. But if you switch to a smart EV tariff — like **Octopus Go** or **Intelligent Octopus** — you can get overnight electricity for as little as **7–10p per kWh**. That cuts your charging costs roughly in half. The catch? To automatically take advantage of those cheap overnight rates, you need a smart charger. Without one, you'd have to manually plug in at 11pm and unplug at 5am — every single night. A smart charger like the **Ohme Home Pro** talks directly to Octopus Intelligent and handles all of this automatically. It knows your car's state of charge, your daily departure time, and the electricity price schedule — and charges accordingly. **The maths:** If you drive 10,000 miles per year in an EV averaging 3.5 miles/kWh, you'll use about 2,857 kWh for charging. At 27p that's £771/year. At 7.5p (Intelligent Octopus off-peak rate), that's £214/year. The saving is over **£550 per year**. A smart charger costs £50–£150 more than a basic one. It pays for itself in the first month. ## The Best Smart Chargers in the UK **Best for tariff integration:** [Ohme Home Pro](/reviews/ohme-home-pro-review/) — integrates directly with Octopus Energy for automated intelligent charging **Best for solar owners:** [Myenergi Zappi](/best-picks/best-home-ev-chargers-uk/) — maximises use of solar energy before drawing from the grid **Best all-rounder:** [Wallbox Pulsar Plus](/best-picks/best-home-ev-chargers-uk/) — excellent app, smart scheduling, compact design ## Do You Need a Smart Charger? **Get a smart charger if you:** - Are on or considering a smart electricity tariff (Octopus Go, E.ON Drive, etc.) - Have or plan to get solar panels - Want detailed charging data and cost tracking - Have two EVs and want intelligent load management **A basic charger might be fine if you:** - Are on a fixed-rate tariff with no off-peak rates - Only occasionally charge at home - Just want the simplest possible setup Our honest opinion: almost everyone benefits from a smart charger. The savings are real, the apps have improved enormously, and the price premium is modest compared to the lifetime savings. ## Is a Smart Charger Required by Law in the UK? Yes — since June 2022, all new home EV chargers sold in the UK must be "smart" chargers meeting government specifications. This means they must be capable of scheduled charging and demand response. In practice, this means all current-market home EV chargers are smart chargers. You can't buy a non-smart new charger for home installation in the UK anymore. ## Ready to Choose?
