Planning an EV charger installation for home? Start by gathering your vehicle details, photos of your parking space, and the questions you want your installer to answer. Choosing an EV charger for home is not just a matter of picking the highest power rating. The charger, your vehicle and the installation proposal should be considered together.
This checklist helps you prepare for a conversation with an installer. It is not a wiring guide. Leave electrical inspections, equipment selection and installation work to a qualified professional. The featured image is an illustration, not a photograph of a customer installation.
Quick answer: what should I prepare?
Prepare your exact EV model and year, a description of your usual parking position, photos of the proposed charger location, and a list of the features you want. Ask for a written quotation that separates the charger from installation work and explains any exclusions.
1. Record your exact vehicle model
Write down the make, model, model year and variant of your EV. If available, include the manufacturer's information about its AC charging capability and charging connector. Do not assume every version of a vehicle has identical charging specifications.
The vehicle's onboard charger matters when planning AC home charging. A higher-rated wallbox alone does not establish the charging rate your car will achieve. Ask the installer to explain the proposed setup using your exact vehicle specifications rather than a headline charger rating.
2. Photograph your usual parking position
Take a wide photo showing how you normally park, plus a closer photo showing where the vehicle's charging port sits. Include any gates, doors, walkways or objects that might affect the charger location.
Think about everyday use: can you reach the charging port comfortably, put the connector away, and keep the parking area usable? Manufacturer installation guidance recommends positioning charging equipment so the cable can reach the car without strain. The installer should confirm the suitable location for the particular charger you choose.
3. Ask how the cable route will be assessed
Show the installer where you would like the charger mounted and ask how the proposed supply route will be evaluated. If requested, provide photos of the outside of your electrical distribution board. Do not remove covers or expose wiring to take photographs.
Ask whether an on-site assessment is needed before the quotation can be finalised. Cable distance, routing and site conditions can affect the work involved. A photo-based estimate and a confirmed installation scope are not necessarily the same thing.
4. Separate essential features from nice-to-have features
Decide how you want to start and manage charging. Do you prefer simple access, RFID cards, app control or scheduling? If a feature matters to your purchase, ask for confirmation that it is included on the exact model and version quoted.
For connected chargers, ask what functions need Wi-Fi, an app account or additional equipment. Avoid relying on a product-family description when different versions may have different features.
5. Request a clearly itemised quotation
Ask the installer to separate the charger price, installation work and optional additions. The quotation should describe what is included rather than rely only on the phrase “standard installation”.
- Which charger model and power option are included?
- What cable route and distance does the proposal cover?
- What mounting work and materials are included?
- What site conditions could change the price?
- How will additional work be agreed before it proceeds?
- What setup, testing and handover are included?
- Who handles charger support and installation-related support?
Compare quotations with the same scope. A lower headline figure is difficult to evaluate if one proposal includes work that another excludes.
6. Plan the handover before installation day
Ask for a demonstration of normal charging operation and the controls available on your chosen model. Confirm who you should contact if the charger displays an error or if you have a question after installation.
Keep the quotation, invoice, model details and warranty information together. Ask the installer to explain the warranty terms for the charger and workmanship separately, including the process for requesting support.
7. Prepare the household for the installation visit
Before the appointment, ask what access the team needs and whether you should expect any interruption to your electrical supply. Agree on the proposed charger position and visible cable route before work begins. If you have a preferred finish, discuss it at the quotation stage rather than assuming it is included.
Clear the agreed work area and arrange access to the parking space. Ask which household member should be available to approve any changes to the scope. If the team discovers extra work is needed, request an explanation and written price before agreeing to it.
8. Use a simple comparison sheet
When comparing two proposals, put the answers side by side. Record the exact charger version, confirmed features, installation scope, exclusions, support contact and warranty terms. Mark unanswered questions as “not yet confirmed” rather than filling in the gaps yourself.
This also helps you avoid comparing a charger-only price with an installed package. Ask each supplier to explain what you would pay for the same agreed scope, and what could change after the site assessment.
A message you can send to an installer
Hello, I am planning a home EV charger installation. My vehicle is [make, model, year and variant]. I have attached photos of my parking space and preferred charger position. Please advise what information you need for a site assessment, which charger version you recommend, and what your quotation includes and excludes. Please also confirm the charger and workmanship warranty terms.
Replace the bracketed details before sending. Share household photographs privately with the installer you choose.
Frequently asked questions
Should I buy the charger before speaking to an installer?
It is sensible to discuss the vehicle, proposed location and installation scope before committing. That conversation helps you check that the equipment and proposed installation suit your needs.
Will a 22kW charger always charge my car faster?
No. Check your vehicle manufacturer's AC charging specifications and ask the installer what the proposed setup can deliver. The wallbox's maximum rating is not a promise of the charging speed your particular car will receive.
Can I get an exact installation price from photos?
Ask whether the figure is an initial estimate or a confirmed quotation. The installer may need further information or an on-site assessment to establish the scope.
What should I send with an installation enquiry?
Send your EV model and year, your general installation location, parking photos, preferred charger position and the features you want. Share household photographs privately with your chosen installer rather than posting them publicly.
What if I am not sure whether my home has single-phase or three-phase power?
Tell the installer you are unsure and ask how they will confirm it as part of the assessment. Do not open electrical equipment or select installation components yourself to answer the question.
Does an installation quotation include the charger?
Check the quotation. Ask for the equipment and installation charges to be identified separately, with the exact model and scope written down. Do not assume that every advertised installation price includes a wallbox.
Discuss your home charging setup with EV Sifu
Explore the E1.1 home EV charger and E8 home EV charger, then ask EV Sifu to confirm the exact model features and installation scope for your home. Use the checklist above to make that conversation more useful.
