What does a free home EV charger survey actually involve?

A home EV charger survey is a 30 to 45-minute in-person visit from a NAPIT-qualified electrician. We assess your property and give you a fixed quote before any work is agreed.

Most national installers ask you to upload photos of your fuse board, measure your own cable runs, and estimate your own WiFi signal strength. If your measurements are off, costs go up on installation day. We do this work ourselves, at your property, before any money changes hands.

By the end of the survey you know exactly what charger we recommend, where it will sit, how the cable will be routed, and what the complete job will cost. No surprises. No follow-up calls with revised numbers.

Why do you need a site survey before installing an EV charger?

Every property is different. A survey identifies what your specific home needs before any work is agreed, so there are no surprises on installation day.

Electrics and safety

Many properties across the Chilterns were built before modern electrical standards. Older homes in Great Missenden, Victorian terraces in Chesham, and farmhouses near Wendover regularly have consumer units that need upgrading before a 7kW charger can be installed safely.

Cable routing

The distance from your consumer unit to where your car parks, your wall thickness, and the construction materials involved all affect price and complexity. What looks simple from a photograph often is not.

WiFi performance

Smart chargers need a stable signal to manage schedules, track usage, and work with tariffs like Octopus Intelligent. A poor signal means a charger that does not perform as it should.

What does your engineer check during the survey?

Our engineer works through five areas: your consumer unit capacity, cable routing options, charger position, WiFi signal strength, and the right charger type for your car and your usage.

Consumer unit and wiring capacity
Cable route from consumer unit to charger position
Charger position on your driveway or in your garage
WiFi signal at the charger location
Charger type suited to your car and habits

Which charger type suits your car and habits?

Tethered chargers have a fixed cable permanently attached to the unit. Untethered chargers use a portable cable you store in the car. We explain the practical difference and help you choose based on your vehicle, your parking setup, and your day-to-day routine.

Common questions about our free home EV charger survey

Yes. Our engineer needs access to your consumer unit, your driveway or garage, and your car's usual parking position. The survey takes around 30 to 45 minutes and we will agree a time that suits you when we call to book.

We can survey rental properties if you are the owner or have written permission from your landlord. Flats require a dedicated off-street parking space and written agreement from the freeholder before we can proceed. We will walk you through what you need during the survey itself.

We install a range of OZEV-approved smart chargers suited to different cars, budgets, and driveway setups. Our engineer will recommend specific models during your survey based on your vehicle and requirements.

The OZEV Electric Vehicle Chargepoint Grant currently applies to flat owners and renters in specific circumstances. Homeowners with private driveways do not currently qualify for a direct government grant, but smart tariffs can significantly reduce overnight charging costs. We will explain the current position clearly during your survey.

We aim to arrange surveys within five to seven working days of your booking in most Chilterns postcodes. If you need something sooner, call us on 01494 977298 and we will do our best to accommodate you.

Yes. There is no cost for the survey and no obligation to proceed with an installation. We carry out free surveys because homeowners who have spoken to a real engineer are far more likely to trust us with the installation. If your property is not suitable for an EV charger, we will tell you honestly.

You receive a written, fixed-price quote by email within 24 hours. Most Chilterns installations are completed within one to two weeks of the survey. After installation you have six months of direct aftercare. If anything goes wrong, you call us and we come back.

We call within one business day to arrange a survey time. Surveys run Monday to Saturday, 08:00 to 19:00.
