What should a home EV charger quotation include?

A useful home EV charger quotation should tell you exactly what will be installed, where it will go, what the electrical work involves and what you will pay. It should leave as little as possible to assumption.

The charger itself: The quotation should name the exact charger model, rather than simply saying “smart charger”. It should explain whether it is tethered with a fixed charging lead or untethered, and identify the cable or connector you will use with your car. If the charger has app control, scheduled charging, solar integration or load management, the quotation should make clear which functions are included and which depend on other equipment.

Your preferred charger may not suit every driveway or electrical installation. We discuss how you expect to charge, where you park and whether you want to use surplus solar generation. That gives you a practical recommendation rather than a specification chosen in isolation.

The proposed position: The quotation should show where the unit will be fixed and how the cable will reach the parking space. The route may run through a loft, garage, utility area or external wall. It should state whether the price allows for surface-mounted cable, concealed cable, wall penetrations, trunking or other protection.

If the charger will sit away from the main building, the quotation should say whether it includes external cabling, additional supports, ducting or trenching. It should also identify who deals with reinstating disturbed surfaces. These details can change the cost considerably, especially on a long driveway or an older property with thick walls.

Electrical capacity: The quotation should record what our survey found at the consumer unit and meter position. It should explain whether the existing installation can support the charger and whether we need to add a circuit, upgrade protective equipment or make changes elsewhere.

Your main fuse and household demand may affect the proposed arrangement. If a full-rate charge could place too much demand on the supply, we may recommend a load-management device or another control method. The quotation should state whether that equipment is included and how it limits charging when other appliances are running.

Older homes may need additional work before the charger can be connected. Our electrical inspection can identify issues such as an unsuitable consumer unit, inadequate earthing or other faults. A clear quotation separates essential remedial work from optional improvements, so you can decide what to do without confusing the charger price with unrelated upgrades.

Work included: Look for a clear list of the physical work covered by the price. This may include mounting the charger, installing the dedicated circuit, fitting protective devices, running and securing the cable, connecting the equipment and making good small penetrations.

The wording should also identify assumptions. For example, it might depend on access to the consumer unit, a particular cable route, suitable wall construction or the vehicle being parked in a stated position. If the actual site differs from those assumptions, the installer should explain the change before carrying out extra work.

Items that may sit outside the price: A quotation should identify possible extras instead of hiding them in vague wording. These can include extensive excavation, long cable runs, asbestos-related work, repairs to an unsafe installation, a new consumer unit, supply changes or work requested after the survey.

VAT should be shown clearly, including whether the quoted total includes it. The document should also state the payment stages, how long the quotation remains valid and how the installer handles changes. We provide written quotations before work starts, so the agreed scope and price are recorded before an engineer begins.

Safety and certification: The price should include the final inspection and electrical tests needed for the installation. It should say which test results and certificates you will receive, rather than treating certification as an unspecified extra.

Our NICEIC-registered electricians carry out the electrical installation and testing. That matters because you receive documented evidence that the charger circuit has been checked, tested and connected correctly. The quotation should also explain any notification made to the relevant network operator and identify any paperwork you need to keep.

Using solar generation: If you already have solar panels or may add them later, the quotation should explain whether the proposed charger can respond to solar generation. It should distinguish between a charger that can use surplus electricity and a complete solar-aware system that requires compatible monitoring equipment.

That distinction prevents an assumption that the charger will automatically charge from solar power. We can discuss the wiring and control requirements during the survey, then list any extra equipment separately if it is not part of the basic installation.

After the installation: Check what support the quotation includes if the charger will not connect to its app or your vehicle does not begin charging. It should name the installer’s responsibility for commissioning and explain what happens if a fault appears in the installation.

The quotation should also identify the charger manufacturer’s warranty and say who you contact about a product fault. That is different from the installer’s responsibility for the wiring and workmanship, so both should be clear.

Questions to ask before accepting:

• Is the exact charger model named?
• Does the price include the dedicated circuit, protective equipment and all expected cable work?
• What route and cable length has the installer allowed for?
• Does the quotation include load management if the electrical supply needs it?
• Are VAT, remedial work and possible extra charges explained?
• Which tests, certificates and notifications are included?
• What assumptions could cause the price or scope to change?
• Who handles commissioning, product faults and warranty queries?

A cheaper quotation may simply leave more of these details unstated. Comparing the written scope, electrical checks, cable route and exclusions gives you a fairer comparison than comparing the charger price alone.
