Switching to an electric vehicle is an exciting milestone. Whether you’ve just picked up a sleek Tesla in Reigate or a family-friendly Nissan Leaf in Redhill, the convenience of charging at home is a game-changer. No more detours to petrol stations or waiting around at public rapid chargers; you simply plug in overnight and wake up to a "full tank."
However, as the demand for electric cars across Surrey continues to soar, so does the number of companies claiming to be experts in EV charging. For the average homeowner, the technical jargon: kilowatts, tethered vs. untethered, load balancing, and DNO notifications: can be overwhelming. This confusion often leads to costly errors.
To ensure your transition to electric driving is as smooth as possible, we’ve put together this guide on the five most common mistakes to avoid when choosing an EV charger installation Surrey specialist.
1. Assuming "Any Electrician" Can Do the Job
One of the most frequent mistakes homeowners make is hiring a general electrician who doesn't specialise in EV infrastructure. While many local sparks are excellent at changing light fittings or adding sockets, EV charging stations are high-draw appliances that run at full capacity for hours at a time. This puts a significant unique stress on your home’s electrical system.
Why Specialisation Matters
An EV charger is not just another appliance; it’s a piece of sophisticated technology that must be integrated correctly with your consumer unit and the wider grid. A specialist installer will understand:
- The 18th Edition Standards: Ensuring the installation meets the latest BS 7671 regulations, including specific requirements for earthing and surge protection.
- NICEIC Approval: Working with an NICEIC Approved Contractor like ADS Electrical ensures that the work is regularly assessed for safety and quality.
- OZEV Authorisation: If you are a landlord or a tenant looking to access government grants, your installer must be authorised by the Office for Zero Emission Vehicles (OZEV).
Choosing an uncertified or inexperienced installer might save you a few pounds upfront, but it could invalidate your home insurance or lead to dangerous electrical faults down the line.
2. Skipping the Professional Load Assessment
Imagine you’re cooking Sunday dinner with the oven on, the power shower is running, and the tumble dryer is mid-cycle. Suddenly, your EV charger kicks in at 7.4kW. If your installer hasn't checked your "Maximum Demand," you could blow the main fuse to your property.
The Importance of a Site Survey
A common mistake is accepting a quote from someone who hasn't seen your fuse board or asked about your other high-load appliances (like electric hobs or heat pumps). A professional EV charger installation Surrey provider will always perform a load assessment.
At ADS Electrical, we look at:
- Main Fuse Rating: Is your incoming supply 60A, 80A, or 100A?
- Consumer Unit Capacity: Is there physically enough room for a new dedicated circuit, and is the board up to modern 18th Edition standards?
- DNO Notification: In Surrey, we usually need to notify UK Power Networks (your Distribution Network Operator) about the new high-load device. A professional handles this paperwork for you.
If your installer doesn't mention "load balancing" or "CT clamps," they might be planning a "blind" installation that could leave you sitting in the dark.
3. Opting for a "Dumb" Charger to Save Money
The UK government introduced the Electric Vehicles (Smart Charge Points) Regulations 2021 for a reason. "Smart" chargers do much more than just deliver electricity; they communicate with the grid to charge when energy is cheapest and demand is lowest.
Buying for Tomorrow, Not Just Today
Some installers might offer older "dumb" units at a discount. These units simply turn on and off. However, choosing a smart charger allows you to:
- Integrate with Solar: If you have (or plan to get) solar panels, smart chargers can divert excess sun power directly into your car.
- Use Off-Peak Tariffs: Save hundreds of pounds a year by scheduling your charge for 2 AM when rates are low.
- App Connectivity: Monitor your usage, lock your charger remotely, and track costs from your phone.
When we provide an EV charger installation Surrey quote, we focus on future-proofing. Your car might change in three years, but your charger should last a decade.
4. Falling for the "Standard Installation" Trap
You’ve likely seen ads for EV chargers with a price tag that includes "Standard Installation." The mistake is assuming your home fits the "standard" criteria. In the world of electrical contracting, "standard" usually means a very short cable run (often under 10 metres), no drilling through thick stone walls, and a modern fuse box that needs zero upgrades.
Avoiding Hidden Costs
Surrey homes, especially in older parts of Redhill or Nutfield, often require more work than a "standard" package covers. Common "non-standard" requirements include:
- Upgrading the Consumer Unit: If your board is old, it won't have the necessary RCD or Surge Protection Devices (SPD) required by law for EV chargers. You can learn more about this on our fuse board upgrades page.
- Trenching: If your driveway is away from the house, cables may need to be buried.
- Long Cable Runs: Charging a car at the end of a long driveway requires thicker, more expensive cabling to prevent voltage drop.
Always insist on a transparent, itemised quote. At ADS Electrical, we pride ourselves on providing free quotes within 24 hours that clearly outline every cost, so there are no surprises on installation day.
5. Overlooking Placement and Accessibility
It sounds simple, but where you put the charger matters immensely. We’ve seen many DIY or poorly planned installs where the charger is placed in a spot that requires the cable to be stretched across a public pavement (a massive trip hazard and legal liability) or where the car’s charging port is on the wrong side.
Professional Advice on Siting
A good installer will talk to you about:
- Tethered vs. Untethered: Do you want a permanent cable attached to the wall (convenient), or just a socket where you plug in your own cable (neater look)?
- The "Reach" Test: Does the cable reach the charging port if you park front-in or reverse-in? What if you get a second EV?
- Weather Protection: While most chargers are IP-rated for outdoor use, placing them in a sheltered spot can extend the life of the unit and the cable.
