How Splash works
Here's the simple version. Splash talks to the charger you already have, in whichever language it already speaks. Nothing to buy, nothing to rewire, nothing new on your wall. And you decide when it's used, every time.
It speaks your charger’s language.
Most home chargers already use a shared open standard called OCPP. It's how chargers and apps talk to each other, and Splash speaks it too. For a few brands we're building a direct link with the manufacturer instead, so you sign in once and approve it. Either way there's nothing to install, nothing to rewire, nothing new on your wall. If your charger is online and reasonably recent, it almost certainly works. We support 15+ brands. Find yours in the connection guides, or message us and we'll check.
It only acts during a booking.
When a guest books a slot, Splash starts that one session, stops it at the end, and notes how much charge was used. That's the whole job. The rest of the time your charger sits quietly, doing nothing for us. No watching, no waiting in the background, no surprises.
You stay in control.
Block off the hours you need the charger yourself. Set your own price. Decide exactly who gets to use it, thanks to Know-your-guest (KYG), so you always know who's pulling onto your driveway. If your plans change, your plans win. Every time.
It works with your cheap hours.
If your electricity plan has the same cheap window every night, like a set overnight rate, you're sorted. Scheduled charging lines your charge up with those cheaper hours so you pay less, automatically. If you're on a plan where the cheap hours move around day to day, like Octopus Intelligent Go, Splash can't work alongside it yet: your supplier decides when your car charges, and we'd only be talking over each other. Message us and we'll let you know as soon as that changes.
Keep your own charger app.
Splash doesn't take over. Your charger's own app keeps working, so you can charge your own car whenever you like and share only the hours you weren't going to use anyway. One exception: if you're on smart charging, where your supplier or charger maker decides when your car charges, your own scheduling is already limited by that. Tell us what you've got and we'll tell you what it means for you.
