Ohme EV Charger Cornwall.
Ohme's chargers talk directly to smart tariffs like Octopus Intelligent Go, automatically shifting your charging to the cheapest overnight rate without you lifting a finger. We fit it as part of a fully certified, NAPIT approved installation, wired to your home's actual supply rather than a generic setup.
Charge at the cheapest time, automatically.
Automatic Off-Peak Charging
Ohme chargers are built around one core idea: charging your car at the cheapest, greenest time possible without you having to think about it. The Ohme Home Pro has a built-in SIM, so it connects directly to smart EV tariffs like Octopus Go or Intelligent Octopus without relying on your home wifi, and automatically shifts your charging to off-peak hours to cut the cost of every charge.
Compact Design, Detailed App
It's also one of the most compact tethered chargers on the market, with a slim design and a genuinely detailed app that shows exactly when you're charging, what it's costing, and lets you set a target charge time so the car is ready when you need it, charged at the cheapest possible rate overnight. If you have solar, Ohme can also be set to prioritise your own generation over grid power, so you're not paying for electricity you're already producing on your roof.
Built for Cornwall Properties
Ohme chargers are OZEV grant eligible where applicable, and the compact tethered design suits Cornwall properties where wall space or cable routing is tight, no separate cable to store, just plug in and go.
Fully Certified Installation
If you're on a smart EV tariff and want the charger to handle the cheap-rate timing on its own, Ohme is built specifically for that job. Get in touch for a free quote and we'll talk through whether Ohme is the right fit for your home.
What Happens on Install Day
On installation day, we'll mount your Ohme charger, connect it to your consumer unit, and pair it with the app so you're charging on your first night. Ohme works with any electric vehicle using the standard Type 2 connector, which covers the vast majority of EVs on UK roads. If you're not sure whether your car's compatible, just ask when you get in touch.

Is Ohme right for you?
Ohme suits you if you're already on, or considering, a smart energy tariff like Octopus Go or Intelligent Octopus. The built-in SIM means it works without relying on your home wifi, which is useful if your charger's somewhere with a weak signal. If you don't currently have a time-of-use tariff, we can talk through whether switching makes sense alongside your install.

I cannot recommend Holloway Electrical highly enough. From the planning of our solar and battery installations through to the final commissioning Jamie's took care of everything. Organised other trades to assist, explained everything that was going on and completed the job on time as promised to an exceptional standard, I could not be happier.
We experienced a very friendly and helpful service from Jamie with our new kitchen electrics. We would highly recommend his services.
We are so pleased with the work that Jamie completed for us today, supplying power to our apartment garage and installing sockets and EV charger. The quality of the work is outstanding. I highly recommend Holloway Electrical Ltd, definitely our electrical professional for all future requirements!
Hi Jamie, Kieran did a great job and we are both very pleased with it. Thank you very much. I would like to discuss with you the electrical box in the kitchen which will need to be replaced. PEH
A lovely local company to deal with. Efficient and left everything clean and tidy. Highly recommend.
Great communication, excellent service, great price, 100% recommend.
We had several quotes from Electricians to install our EV charger which varied dramatically. Jamie’s quote was by far the most reasonable and he was the only one who bothered to come to our home and look at the charger etc. before taking on the job. He arrived on the agreed date of installation and was personable, efficient and tidy. I would have no hesitation in recommending Jamie and would be happy to call on his services again in the future.
