Splash

Airbnb your EV charger

Make your charger earnwhile you sleep.

Splash connects your home charger with EV drivers nearby. You earn; they skip the public-charger queue.

Built in London, sharing across the UK.

One charger.
Two neighbours.

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

Skip to the end

07:40. Martin at his front door with a mug and his phone, his charger on the wall and the drive empty.

01 Share 07:40

Share the hours you don't use.

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.

Sharing on your schedule

Maya on her terraced street, no driveways, cars parked nose to tail, checking her phone.

02 Find 09:12

A charger three streets away.

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

Maya at her kitchen table with a cup of tea and toast, booking on her phone.

03 Book 09:15

Book the exact hours.

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

Maya's green car on Martin's drive, plugged into his charger.

04 Charge 10:00

Scan, plug in, get on with your day.

Maya's booking is her key. She scans, plugs in and gets on with the day. Martin doesn't need to be there. Every kWh is counted by the charger.

Scan and go

Martin outside his front door in the afternoon, smiling at his phone.

05 Earn 15:04

Get paid without lifting a finger.

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

Dusk. Martin at his front door, his own car plugged in on the drive for the night.

Your street has a Martin.
And a Maya.

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.

Sharing = Caring

You open up your charger when it suits you, and stay in control the whole time. The money's nice. The thank-you text from a neighbour is nicer.

Getting started

What is Splash?

Think Airbnb, but for EV chargers. Hosts share the charger on their driveway, guests book a slot and charge. That's it.

Is Splash available in my area?

We're a small team, growing out from London. Open the app to see chargers near you. If there aren't any yet, become a host and you'll be the one who starts it on your street.

How do I get started?

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.

Do I need a driveway to become a host?

Yes. You'll 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're a renter or flat owner, it's worth checking whether you're eligible for a grant toward installation.

All getting started questions

Hosting

How much can I earn as a host?

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 your energy cost. The earnings calculator shows what your own rate and hours would make.

What does it cost to host?

Nothing to start. Our platform fee is normally 10%, but it's set to 0% while we grow. Join now and you keep the lot.

Will strangers turn up at my house?

No. Your charger only opens up to people who've booked, and you see exactly who's coming before they arrive.

How do I connect my charger to Splash?

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's a one-time setup.

Stuck, or not sure your charger is supported? Message us on WhatsApp and we'll help.

Can I still use my own charger app?

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're on it, tell us what you've got and we'll tell you exactly what it means for you.

What about insurance?

We're working on insurance options for hosts right now. In the meantime, it's worth checking whether your home or charger policy already covers other people using it.

All hosting questions

Booking and charging

How does charging work?

Book a slot, turn up, scan the QR code, plug in. You're charging. Follow the whole session in the app.

How much does it cost to charge?

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.

Can I book in advance?

Yes, up to 7 days ahead.

What if I need to cancel?

No problem. Cancel for free any time before your slot starts. Open the app, go to your bookings, tap the booking, and choose Cancel.

Can I extend a booking once it has started?

Not yet. For now, you'd make a separate booking for the extra time.

Do I get anything when I join?

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.

All booking and charging questions

Payments and earnings

How do I pay as a guest?

You pay an estimate when you book, then at the end you're only charged for what you actually used. It all happens automatically in the app.

How do hosts get paid?

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.

How do I withdraw my earnings?

Withdraw from your wallet whenever you like. There's a small processing fee of 0.5%, and you'll see it on the withdrawal screen before you confirm.

Do I need to pay tax on what I earn?

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.

All payments and earnings questions

Compatibility and tariffs

Is my charger compatible?

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'll check.

I'm on a smart tariff like Intelligent Octopus Go, can I use Splash?

Not yet, and we'd 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's 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're fine: scheduled charging lines your charge up with it automatically.

On Intelligent Octopus Go? Message us and we'll let you know the moment this changes. See how Splash works →

Safety and support

Is Splash safe?

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

What if something goes wrong during a session?

Message us on WhatsApp, 8am to 8pm every day. We're a small team, so outside those hours it can take a bit longer, but we'll always get back to you as fast as we can.

How do I contact support?

WhatsApp is quickest: +44 20 4538 7763 (8am to 8pm daily). Prefer email? Use the contact form and we'll reply there.
