Installing Commercial EV Chargers: What to Expect, Step by Step
From first site visit to first paying charge — what actually happens when a business adds EV charging.
Adding EV chargers to a commercial site isn't complicated, but it does involve more moving parts than most people expect. Knowing the sequence upfront makes the project faster, cheaper and considerably less stressful.
1. Site survey and load assessment
Every credible installation starts with a site visit and a look at your existing electrical capacity. The question isn't 'can we fit a charger?' — it's 'how many, what speed, and where, given what your incoming supply can handle?'
2. Charger selection
Choices break down across a few axes:
- AC vs DC (slow/destination vs fast/rapid)
- Single vs dual outlet per unit
- Tethered cable vs socket only
- Back-office and payment platform
- Smart load-balancing capability
The right answer depends on dwell time, expected utilisation and whether you want chargers to integrate with onsite solar and battery.
3. Grid connection (sometimes)
Larger installations may need a DNO (Distribution Network Operator) application to increase the site's supply capacity. This is usually the longest single step in the timeline, and it pays to start it early.
4. Civils and installation
Trenching, cable runs, base pads or wall-mounting, bollards, signage, line painting. Done well, this is the bit guests notice — chargers should feel like a designed part of the site, not an afterthought bolted to a wall.
5. Commissioning and back-office setup
Each charger is registered to a payment and management platform: tariff structure, RFID access for staff/fleet, reporting dashboards, integration with mapping apps so EV drivers can find you.
6. Ongoing operation
Modern chargers are remotely monitored. Faults are usually picked up before users complain, software updates land over the air, and tariffs can be adjusted in response to electricity costs or demand.
How long does it all take?
Small installs (a few AC chargers, no grid upgrade) can be live in 4–6 weeks. Larger sites needing a DNO application typically land in 3–6 months. Either way, the time spent on planning and design pays itself back many times over once the chargers are operational.
