Smart energy, cheaper bills
Get Started FreeWorks with Tesla, Polestar, Hypervolt & home batteries
Unlike a fixed-rate tariff where you pay the same price all day, Agile tariffs change every 30 minutes based on wholesale energy costs. Prices are published the evening before, so you know exactly what you'll pay.
Wattson watches tomorrow's prices and automatically schedules your devices to use the cheapest slots.
Connect your EV or let your battery do its thing. Wattson detects it automatically.
Wattson analyses tomorrow's half-hourly prices and picks the cheapest time to charge.
Charging happens overnight at the lowest rates. Wake up to a full battery and a smaller bill.
Agile tariffs aren't for everyone. Here's who benefits most.
EVs are the biggest single electricity load in most homes. Shifting a 7kW charge from peak (35p) to overnight (5p) saves over £2 every session.
Batteries can charge overnight at 5p and discharge during the 35p evening peak — earning 30p/kWh in arbitrage, every single day.
Solar + battery + Agile is the ultimate combo. Generate free energy by day, export at high prices, charge from the grid when it's nearly free.
Even without an EV or battery, running the dishwasher and washing machine overnight instead of at 6pm makes a difference.
Agile prices can spike during cold winter evenings — sometimes above 50p/kWh. If you use a lot of electricity at peak times without shifting it, you could pay more than a fixed tariff. That's exactly why Wattson exists: to automatically avoid the expensive slots and make sure Agile always works in your favour.
Connect your EV or battery and Wattson does the rest. No hardware needed.
