If you’ve recently made the switch to an electric vehicle (EV) in Redhill or the surrounding Surrey area, you’ve already taken a massive step toward lower running costs. But if you’re still charging your car on a standard "flat-rate" electricity tariff, you are likely leaving hundreds of pounds on the table every year.
As we move through 2026, the energy landscape has evolved. We are no longer just looking for the "cheapest" supplier; we are looking for the "smartest." By pairing a high-quality home charging point in Surrey with a dedicated smart EV tariff, local homeowners are slashing their fuel bills by up to 70% compared to petrol or standard electricity rates.
In this guide, the team at ADS Electrical: your local NICEIC Approved Contractor: breaks down the best smart tariffs available right now and explains how the right installation can unlock these massive savings.
What is a Smart EV Tariff and How Does It Work?
A smart EV tariff (often called a "time-of-use" tariff) offers different prices for electricity depending on when you use it. Because the National Grid has surplus energy overnight when demand is low, suppliers offer incredibly cheap rates during these "off-peak" windows.
For an EV driver in Redhill, this is a game-changer. Instead of paying 25p per kWh during the day, you could be paying as little as 7p per kWh while you sleep.
The Two Types of Smart Tariffs:
- Static Time-of-Use: These have fixed cheap hours (e.g., 12:00 AM to 5:00 AM). You set your car to charge during these times.
- Dynamic/Intelligent Tariffs: These are more advanced. Your energy supplier communicates directly with your car or your smart charger to find the cheapest, greenest slots throughout the night, sometimes even adding extra cheap windows if there’s an abundance of wind or solar power on the grid.
To access these rates, you need two things: a smart meter and a compatible smart EV charger installed by a professional electrician in Redhill.

Comparison: The Top UK EV Tariffs in 2026
The market is competitive, and for Surrey residents, the choice usually comes down to the "Big Three" providers. Here is how they stack up in mid-2026:
| Tariff Name | Off-Peak Rate (Approx.) | Off-Peak Window | Key Benefit |
|---|---|---|---|
| EDF GoElectric | ~6.99p/kWh | 11:00 PM – 6:00 AM (7 hours) | The longest fixed window and often the lowest rate per kWh. |
| Intelligent Octopus Go | ~7.00p – 8.00p/kWh | 11:30 PM – 5:30 AM (6 hours +) | "Smart Dispatch" adds extra cheap slots outside the core window. |
| British Gas Electric Driver | ~9.9p/kWh | 12:00 AM – 5:00 AM (5 hours) | Great for existing customers, though often slightly higher per kWh. |
Which is best for a Surrey homeowner?
- EDF GoElectric is currently the champion for those with larger battery capacities (like the Audi Q8 e-tron or Tesla Model X) because that 7-hour window allows for a more substantial charge without dipping into daytime rates.
- Intelligent Octopus Go is the tech-lover's choice. If you have a compatible charger (like the Ohme Home Pro or Zappi) or a compatible vehicle, Octopus can manage your charging automatically to ensure you always use the cheapest possible energy.
Why a Compatible Smart Charger Matters
You cannot simply plug a "dumb" charger into the wall and expect to save money. To qualify for the best rates: specifically the Intelligent Octopus Go tariff: your hardware must be able to "talk" to the supplier.
This is where expert ev charger installation in Surrey becomes vital. As NICEIC Approved Contractors, we ensure that your charger is not only safely integrated into your home's consumer unit (upgraded to 18th Edition standards) but also correctly commissioned to sync with your energy provider's app.

At ADS Electrical, we specialize in installing the latest smart units that unlock these tariffs. Whether you are in Redhill, Reigate, or Merstham, getting the right setup is the difference between a "convenience" and a "financial investment."

How Much Can Surrey Homeowners Save?
Let’s look at the math for a typical commuter living in Redhill who drives 10,000 miles a year (roughly 200 miles a week).
- Standard Electricity Tariff (~25p/kWh): Annual charging cost approx. £715.
- Smart EV Tariff (~7p/kWh): Annual charging cost approx. £200.
- Total Annual Saving: £515.
Over three years, that’s over £1,500 in savings: more than enough to cover the initial cost of your home charging point in Surrey. When you compare this to the cost of petrol or diesel for the same mileage (which can exceed £1,800/year), the move to smart home charging is one of the best financial decisions a Surrey resident can make.
Local Context: The Redhill Commute
Many of our clients in Redhill commute via the A23 or M25 toward London or Gatwick. These stop-start journeys can be taxing on fuel efficiency. By charging at home overnight, you ensure you leave every morning with a "full tank" at a fraction of the cost of public rapid chargers, which can charge upwards of 75p/kWh in 2026.

Practical Steps to Get Started
Ready to stop overpaying for your energy? Here is the roadmap to cheaper driving:
- Check Your Meter: You must have a smart meter (SMETS2) so your supplier can track your half-hourly usage. If you don't have one, your energy supplier will usually install one for free.
- Choose Your Tariff: Compare Octopus, EDF, and British Gas. Look not just at the night rate, but also the day rate, as you'll still be using regular appliances during the day.
- Select a Smart Charger: Ensure the charger you choose is compatible with your desired tariff. Not all chargers work with all "intelligent" features.
- Hire Professional Electric Car Charger Installers in Surrey: This is not a DIY job. A professional installation ensures your home's electrical system can handle the sustained high load of an EV charger.
- Claim Your Commissioning: Once installed, we help you set up the app and link it to your energy provider to start the "smart" handshake.
