You’ve probably noticed more electric vehicles (EVs) appearing in your staff car park or fleet lately. And with the 2035 ban on new petrol and diesel cars looming, shifting your Dorset business toward electric isn't just a "green" choice anymore, it’s a smart financial move.
But with energy prices remaining a top concern, the timing of your investment matters. According to the latest Cornwall Insight forecasts from May 2026, the Ofgem price cap is expected to rise by £209, reaching an annual average of £1,850 for typical households this July. For businesses, this volatility, driven largely by global instability and the Middle East conflict, means your electricity unit rates are likely to hover around 26p/kWh.
So, how do you keep your charging costs down while providing a reliable service for your team? It starts with picking the right hardware.
Between the Zappi, Ohme, and Tesla Wall Connector, there isn't a single "perfect" charger. Instead, the best choice depends entirely on how your business operates. Are you looking to soak up free solar energy? Do you need to track every penny for expense claims? Or do you just want a robust, no-frills workhorse?
Let's break down the big three so you can decide which one fits your Dorchester office or Poole depot best.
The Zappi: The Solar Specialist
If your business already has solar panels, or you’re planning to calculate your ROI for a new commercial solar setup, the myenergi Zappi is likely your frontrunner.
Most EV chargers are "dumb" in the sense that they pull whatever power they need from the grid. But the Zappi is different. It’s designed to talk to your solar PV system. Using its "Eco" and "Eco+" modes, it can sense when your panels are producing more energy than your building is using. Instead of letting that green energy spill back into the grid for a low export rate, the Zappi diverts it straight into your vehicles.
Why it’s great for Dorset businesses:
- Three-Phase Power: If your warehouse or office has a three-phase supply, the Zappi can deliver up to 22kW of power. That’s three times faster than a standard home charger.
- Grid Independence: By using your own solar energy, you're effectively charging your fleet for free. This is a massive hedge against those £1,850+ energy bill forecasts.
- Ecosystem: It works seamlessly with other myenergi products, helping you manage energy flows across your entire site.
But there’s a small catch. The Zappi hardware is often the most expensive of the three. We understand if you’re scratching your head at the price tag, but remember: the long-term savings from solar diversion often pay for that "premium" within a few years.
The Ohme Home Pro: The Tariff Ninja
Does your business have a fleet of drivers who take their vans home, or do you have pool cars that need to be charged as cheaply as possible? The Ohme Home Pro might be your best friend.
While the Zappi focuses on solar, the Ohme focuses on data and tariffs. It’s built to integrate directly with smart EV tariffs, such as those from Octopus Energy (we’re proud to be an Octopus Trusted Partner, by the way). The Ohme app "talks" to the grid and automatically schedules your charging for the cheapest hours, often in the middle of the night when rates drop significantly below that 26p/kWh average.
What makes it stand out:
- Precision Reporting: The Ohme app provides incredibly detailed logs. You can see exactly how many kWh were added, how long it took, and, crucially, exactly what it cost.
- Expense Claims Made Easy: If you need to reimburse staff for charging at the office or at home, this data is gold. No more guesswork or "rough estimates."
- Built-in Screen: Unlike many modern chargers that are just a blank box, the Ohme has a clear digital display so you can see your status at a glance without opening an app.
One thing to note for larger Dorset businesses: the Ohme Home Pro is currently a single-phase-only unit (7.4kW). If you have a three-phase supply and need that 22kW punch, you might need to look elsewhere.
The Tesla Wall Connector: The Fleet Workhorse
Don't let the name fool you, you don't need a Tesla to use the Tesla Wall Connector Gen 3. It’s a Type 2 charger, meaning it will charge almost any modern EV, from a Ford E-Transit to a Porsche Taycan.
Tesla’s approach is all about simplicity and reliability. It doesn't have the complex solar-tracking of the Zappi or the deep tariff-syncing of the Ohme. Instead, it offers a sleek, robust, and surprisingly affordable piece of hardware that just works.
The big benefits for your business:
- Load Sharing: This is its "killer feature" for commercial sites. You can link up to six Tesla Wall Connectors together on a single circuit. They will "talk" to each other to ensure they don't overload your building's power supply, automatically balancing the energy between cars.
- Durability: It’s built to handle the elements, with a lightweight but very tough design. It looks professional in any corporate car park.
- Brand Synergy: If your fleet is already 100% Tesla, the integration is flawless. Drivers can manage everything through the same app they use for the car.
As a Tesla Powerwall Certified installer, we’ve seen how well these units perform. But be aware: if you aren't using Tesla vehicles, you’ll lose some of the granular data logging that the Ohme provides.

Saving Money with the WCS Grant
Before you hit the "buy" button, you need to know about the Workplace Charging Scheme (WCS).
The government is currently offering grants of up to £500 per socket (covering up to 75% of the total cost). For a Dorset business, you can claim this for up to 40 sockets across all your sites. That is a potential £20,000 saving on your infrastructure.
And that's not just for staff cars. If you are a small accommodation business: like a boutique hotel in Weymouth or a B&B in the New Forest: you can also use this grant to provide charging for your guests.
But remember: you must apply for the voucher before the installation starts, and you must use an OZEV-approved installer.
