As the leafy lanes of Surrey become increasingly populated with electric vehicles (EVs), homeowners from Redhill to Reigate are looking for more than just a way to plug in. With over 46,000 ultra-low emission vehicles already registered in the county, a number growing by nearly 30% year-on-year, the demand for smart, sustainable home charging has never been higher.
For many Surrey residents, especially those with detached or semi-detached homes and existing solar PV systems, the myenergi Zappi has become the gold standard. But is it worth the premium over a standard charger? As a leading electrician in Redhill, ADS Electrical has installed hundreds of these units. In this guide, we’ll explore why the Zappi is uniquely suited to the Surrey lifestyle and whether it’s the right investment for your home.
The Surrey EV Landscape: Why "Smart" Matters
Surrey has one of the highest rates of EV adoption in the UK. Our local infrastructure is expanding rapidly, with Surrey County Council aiming for 10,000 public chargepoints by 2030. However, for most homeowners, the real convenience (and cost-saving) happens on the driveway.
If you have a driveway in Redhill, Reigate, or the surrounding villages, you have a massive advantage. You aren't just buying a "plug"; you’re installing a piece of energy management technology. This is where the Zappi excels. Unlike "dumb" chargers that simply pull power from the grid at a fixed rate, the Zappi is "eco-smart." It communicates with your home's energy supply to ensure you’re charging in the most efficient way possible.
How the Zappi Works with Solar PV
The standout feature of the Zappi is its ability to integrate seamlessly with solar panels and even small-scale wind turbines. Many Surrey homes have invested in solar PV over the last decade, but a common frustration is "exporting" that green energy back to the grid for a measly few pence per kWh, only to buy it back at much higher rates in the evening.
The Zappi solves this by using three distinct charging modes:
- ECO Mode: This is the "best of both worlds." It prioritises solar energy but tops up from the grid to ensure a minimum charge rate. It’s perfect for the typical British weather where clouds can suddenly interrupt your solar harvest.
- ECO+ Mode: This is where the magic happens. In this mode, the Zappi will only charge your car using surplus green energy. If a cloud passes over or you turn on the kettle, the Zappi will pause or slow down the charge to ensure no grid power is used. This effectively allows you to drive on "free" sunshine.
- Fast Mode: When you need to get to a meeting in London or a school run in a hurry, Fast Mode operates like a standard 7kW charger, pulling maximum power from the grid and solar combined.
Is It Worth the Investment? The Financial Breakdown
A professional EV charger installation Redhill using a Zappi unit generally costs more upfront than a basic, non-solar-compatible charger. However, the ROI (Return on Investment) for Surrey homeowners is often very attractive.
The Savings Calculation
- Grid Charging: At current UK electricity rates, charging from the grid might cost you around 8p per mile.
- Solar Charging: Using surplus solar energy with a Zappi costs effectively 0p per mile (after the initial solar installation cost).
- Annual Savings: For a typical driver doing 8,000 to 10,000 miles a year, using a Zappi to maximise solar consumption can save between £400 and £800 annually compared to grid-only charging.
Most our clients in Surrey find that the Zappi pays for itself in just 2 to 3 years. After that, your commute is being powered by the roof over your head.
Why Professional Installation is Non-Negotiable
Installing an EV charger is not a simple DIY task or a job for an unqualified "handyman." It involves high-voltage electrical work that must comply with the 18th Edition Wiring Regulations (BS 7671).
As an NICEIC Approved Contractor, ADS Electrical ensures that your installation is not only functional but safe. We specialise in fuse board and consumer unit upgrades, ensuring your home’s electrical system can handle the sustained 7kW load of an EV charger without overheating or tripping.

Beyond Solar: Future-Proofing Your Home
Even if you don't have solar panels yet, the Zappi is a wise choice. It is a fully featured smart charger that allows you to schedule charging during off-peak hours (like the Octopus Intelligent or Go tariffs). This means you can still save significantly by charging at 7.5p/kWh overnight while your car is parked.
Furthermore, the Zappi integrates with the wider "myenergi" ecosystem, including the eddi (which diverts surplus solar to heat your water) and the libbi (home battery storage). By installing a Zappi today, you are future-proofing your Surrey home for a complete smart-energy transition.
