Martin's car charged overnight, so the charger just sits there for the day. Sharing stays on, and his own charging hours stay reserved: guests only see the rest.

Airbnb your EV charger
Martin's charger sits idle most of the day. Maya lives three streets away and has nowhere to plug in. Here is their Saturday.

02 Find 09:12
Maya's street has no driveways. She opens Splash and finds Martin's charger, a four minute drive from her door.

03 Book 09:15
She books 10:00 to 15:00 from her kitchen table. Charge now or up to 7 days ahead. No queue, no gamble.
Bookable chargers
04 Charge 10:00
Maya's booking is her key. She scans, plugs in and gets on with the day. Martin does not need to be there. Every kWh is counted by the charger.
Scan and go
05 Earn 15:04
Maya waves goodbye, and Martin's phone lights up on the lawn: 35 kWh shared, £14.00 in his wallet, and a thank-you from her.
Charge it forward
Some neighbours have a charger that sits idle all day. Others have nowhere to plug in. Splash connects them.
Martin and Maya's day is an illustration. Their numbers assume a 7kW charger at 40p / kWh, the rate our earnings calculator uses. Hosts set their own price.
You open up your charger when it suits you, and stay in control the whole time. The money is nice. The thank-you text from a neighbour is nicer.
Get the app to start sharing
Chargers from a growing list of brands join Splash with a one-time setup. See how yours connects in the guides, and message us for assistance.
See the connection guidesThe hours your charger sits unused turn into steady income, and a charge for a neighbour who needs one.
Hours booked per month versus earnings a year
Illustrative earnings from sharing: a year with a 7 kW charger at 40p / kWh, before the 10% host fee and your energy cost. You set your own price.
Think Airbnb, but for EV chargers. Hosts share the charger on their driveway, guests book a slot and charge. That is it.
We are a small team, growing out from London. Open the app to see chargers near you. If there are not any yet, become a host and you will be the one who starts it on your street.
Guests: download the app, find a charger near you, book your slot.
Hosts: download the app and it walks you through connecting your charger, step by step. Need a hand? Message us on WhatsApp.
Yes. You will need a private driveway or off-street parking with a compatible charger installed. The connection guides list every brand that works with Splash today.
If you are a renter or flat owner, it is worth checking whether you are eligible for a grant toward installation.
It comes down to how often your charger gets booked. As a rough guide, a standard 7kW home charger can earn roughly £504 to £3,024 a year. The top end takes steady weekly bookings.
These are estimates of what sharing brings in, before the 10% host fee and your energy cost. The earnings calculator shows what your own rate and hours would make.
Nothing to start. The 10% host fee applies now, and it comes out of what your bookings earn.
No. Your charger only opens up to people who have booked, and you see exactly who is coming before they arrive.
Download the app and it walks you through connecting your charger, step by step. The connection guides show how it works for your brand. It is a one-time setup.
Stuck, or not sure your charger is supported? Message us on WhatsApp and we will help.
Yes, with one thing worth knowing. Your charger's own app carries on working, and Splash only steps in during a guest's booking or your own scheduled charge.
The exception is smart charging, where your energy supplier or your charger's maker decides when your car charges. That already takes scheduling out of your hands before Splash is anywhere near it, so if you are on it, tell us what you have got and we will tell you exactly what it means for you.
We are working on insurance options for hosts right now. In the meantime, it is worth checking whether your home or charger policy already covers other people using it.
Book a slot, turn up, scan the QR code, plug in. You are charging. Follow the whole session in the app.
You pay the host's rate per kWh (the units your charge is measured in), plus a £1.50 platform fee and a 2% service fee. You see the full price before you book. For example, 35 kWh at 40p comes to £15.78 with fees.
Yes, up to 7 days ahead.
No problem. Cancel for free any time before your slot starts. Open the app, go to your bookings, tap the booking, and choose Cancel.
Not yet. For now, you would make a separate booking for the extra time.
Yes. You get 5 kWh of free charging when you sign up, enough for your first top-up. Refer a friend and you both get 10 kWh. We call it Charge It Forward.
You pay an estimate when you book, then at the end you are only charged for what you actually used. It all happens automatically in the app.
Your earnings land in your in-app wallet straight after each session finishes. Every session is logged, so you can see exactly where the money came from.
Withdraw from your wallet whenever you like. There is a small processing fee of 0.5%, and you will see it on the withdrawal screen before you confirm.
If it applies to you, reporting your earnings to HMRC is down to you. The current tax-free allowance for this kind of gross income is £1,000.
Splash works with a growing list of charger brands, including myenergi, Ohme, Tesla, Wallbox, Zaptec, Easee and Rolec EV, and we add more as we check them.
For some, like myenergi, Easee, Ohme, Tesla, Wallbox and Zaptec, you sign in to your charger's account once and approve the link. For others, you point your charger's own settings at Splash. The connection guides show how yours connects.
Not on the list, or not sure? Message us and we will check.
Not yet, and we would rather say so plainly. On plans where the cheap hours move around night to night, like Intelligent Octopus Go, Octopus decides when your car charges: it sends the charger a live nudge whenever the price is right. There is no schedule sitting on your charger for us to work around, so Splash and Octopus would just be talking over each other.
If your plan has the same cheap window every night, you are fine: scheduled charging lines your charge up with it automatically.

Yes. Your charger only opens to people who have booked, you see who is coming before they arrive, and every session starts with a QR scan. No strangers turning up unannounced.
