What to Expect on EV Charger Installation Day
For most homeowners, an EV charger installation is one of the easier home improvements they'll commission — typically a 2–4 hour job by a single engineer with minimal disruption. But knowing what happens and what to prepare can make the day run more smoothly. This guide walks through the complete ALPS Electrical EV charger installation process, from pre-visit preparation to the documentation you receive at the end.
Before the Installation: What to Prepare
In the days before installation, your installer should confirm:
- Charger location: The wall where the charger will be mounted (typically the exterior wall of the garage, or a side wall facing the driveway). The closer to the consumer unit, the simpler and cheaper the cable run.
- Cable route: Whether the cable runs internally (through the garage ceiling/wall, through the property) or externally (surface-mounted conduit on the exterior wall). Internal routing is neater; external is quicker.
- Consumer unit access: Clear access to your fuseboard so the engineer can install the new circuit breaker and run the cable to the charger location.
- Wi-Fi details: Most smart chargers require connection to your home Wi-Fi during commissioning. Have your network name and password to hand.
- OZEV eligibility: If you are claiming the £350 OZEV grant, your installer needs your vehicle registration number to confirm eligibility.
The Installation Process: Step by Step
A standard domestic EV charger installation follows this sequence:
- Site assessment (15–20 minutes): The engineer inspects the consumer unit, confirms the cable route, and checks that the installation matches the pre-survey assessment. Any unexpected issues (limited spare ways in the consumer unit, difficult cable route) are identified and discussed before work starts.
- Cable installation (45–90 minutes): A 6mm² or 10mm² twin-and-earth cable is run from the consumer unit to the charger location. This is the most variable part of the job — a short, direct run through a garage takes 45 minutes; a complex route through multiple rooms or a long external run takes longer.
- Circuit protection installation (15–30 minutes): A dedicated 32A MCB or RCBO is fitted in the consumer unit for the EV charger circuit. Surge protection is fitted if required.
- Charger mounting and wiring (20–30 minutes): The charger unit is fixed to the wall at the chosen location and the supply cable is connected internally.
- Commissioning and app setup (20–30 minutes): The charger is powered on, connected to your Wi-Fi, and the app is configured. For Ohme, this includes Octopus Energy API connection if you're an Octopus customer. For Zappi, solar divert mode is configured if you have solar panels. Test charging is confirmed.
- Paperwork (15 minutes): You receive the Electrical Installation Certificate, OZEV grant claim confirmation, and charger manufacturer warranty documentation.
Total time for a standard installation: 2–3.5 hours.
What Paperwork Do You Receive?
A compliant EV charger installation generates the following documentation:
- Electrical Installation Certificate (EIC): Confirms the electrical work complies with BS 7671. NAPIT-registered contractors issue this directly — you don't need a separate building control certificate.
- NAPIT notification confirmation: Your local council building control is notified automatically by NAPIT on your behalf.
- OZEV grant confirmation: If applicable, confirmation that the grant application has been submitted and approved.
- Charger manufacturer warranty card or registration: Typically registered online by the engineer during commissioning.
Keep the EIC with your property documents — it is required at property sale and by mortgage lenders.
