One of the first questions after buying a new EV is: "How much will it cost to install a Wallbox at home?" The honest answer — it depends. Two neighbours in the same building can get quotes that differ by 2×.
This article breaks down what drives Wallbox installation cost in Baku, what's actually included in a typical job, how Sharjet's free-installation programme works, and which permits you need.
What drives the cost?
The price of an installation is mostly driven by these factors:
- Distance from the electrical panel to the charger. 5 metres is simple. 25 metres is a serious cabling job.
- The path the cable takes. Surface-mounted along the wall? Inside the wall? Across floors? Each is different work.
- Existing panel capacity. Can your panel handle an extra 32 A circuit, or does it need an upgrade?
- Number of phases. A single-phase grid maxes out at 7.4 kW. For 11 kW you need 3-phase.
- Mounting situation. Wall mount in a villa garage — easy. Pole mount in open parking — more components.
- Permits and paperwork. In a multi-unit building, you need building approval and an electrical sign-off.
Typical components
A standard installation includes:
| Component | Purpose |
|---|---|
| Heidelberg Wallbox | The charger itself, including the 7.5 m Type 2 cable |
| Type B RCD | The special residual-current device required for EV chargers |
| MCB breaker | Overcurrent protection |
| Cable (3×6 mm² or thicker) | Dedicated feed from panel to charger |
| Cable trunking/conduit | Clean routing of the cable |
| Earthing check | Re-test of existing earthing and reinforcement if needed |
| Installation + commissioning | Certified electrician's work and a real charging test |
Exact specs are determined after the site survey — every home is different.
How does free installation work?
When you buy a Heidelberg Wallbox from Sharjet, standard installation is included free. That covers:
- Certified electrician and installation crew
- Up to 15 metres of standard cabling (3×6 mm² or thicker)
- Type B RCD + MCB breakers
- Standard wall mounting
- Connectors, terminals, and cable trunking
- Installation certificate and warranty paperwork
- Live test with your car
Non-standard extras (e.g. more than 30 metres of cable, wall coring, main panel upgrade) are quoted separately — but the full proposal is written and agreed in advance. No surprise pricing.
The exact price depends on your home's electrical setup. After a quick site survey or a couple of WhatsApp photos, we give you a clear quote. Get in touch for pricing.
How long does installation take?
- Site survey (consultation): 30–60 min
- Written quote: within 24 hours
- Installation itself: 3–6 hours (a full day in complex cases)
- Paperwork: completed the same day as the install
From the moment you order a Wallbox until you charge at home, the usual timeline is 3–7 days.
TTQ permits and electrical sign-off
Two pieces of paperwork are involved with Wallbox installation in Baku:
- Installation certificate. Signed by the certified electrician after every install. It lists the protection breakers used, cable cross-section, and earthing test results. This document is needed for any service work during the warranty period.
- Building consent (apartments only). If you live in an apartment block and want to install in the parking, you need written consent from the building management (MTK/HOA) first. The Sharjet team helps with this — we prepare the necessary forms and technical letter.
For a private house or villa, this consent is not required — you are modifying your own grid.
Apartment vs villa: key differences
| Aspect | Villa / private house | Apartment building |
|---|---|---|
| Consent needed? | No | Yes — from building management |
| Typical cable length | 5–15 m | 15–50 m (to parking) |
| Phase availability | Often 3-phase | Usually 1-phase, can be upgraded |
| Installation time | 3–5 hours | 5–8 hours |
| Extra costs | Minimal | Trunking, communal-area work add-ons |
Maintenance and servicing
Once installed, a Wallbox is essentially maintenance-free. The minimum recommended routine:
- Visually check the cable and connector every 6 months (damage, cracks, dirt).
- Once a year, ask the Sharjet team for a breaker test (free during the warranty period).
- If you ever notice unusual noise, smell, or appearance — stop using immediately and contact us.
Heidelberg's 3-year warranty covers any manufacturing defect. All service is local to Baku — no shipping back to Germany.
