Electrical engineering and installation for EV charging
HV and LV electrical installation for commercial EV charging infrastructure. From grid connection to charge point, delivered safely, compliantly, and on programme
HV and LV installation for commercial EV charging
ADDCharge delivers specialist HV and LV electrical installation for EV charging infrastructure, supporting commercial and fleet operators across the UK. Our electrical engineering service is designed specifically for high-power EV environments, where grid capacity, programme certainty, and long-term reliability are critical to project success.
Unlike general electrical contractors, ADDCharge operates at the interface between civil engineering, grid connections, substations, and live electrical networks. This allows us to deliver electric vehicle fleet charging infrastructure at scale, safely, compliantly, and ready for future growth.
CASE STUDY
50 EV chargers across a live Arriva bus depot, indoors and out.
A bespoke structural steel solution to carry 20 overhead charger reels inside the depot, plus 25 external chargers, delivered for Zenobe in 26 weeks.
HV and LV capability
Few electrical contractors work across both HV and LV in commercial, multi-site EV charging installations. ADDCharge does – from 11kV and 33kV high voltage works to LV distribution and charge point connection.
HV Electrical Installation
We deliver HV electrical installation typically at 11kV and 33kV, covering:
- HV network design and installation
- Substation installation including transformers, switchgear, and protection systems
- Grid connection infrastructure and private HV networks
- ICP-delivered HV works
- Integrated earthing and containment
LV electrical installation
Our LV electrical installation covers the full distribution scope from substation secondary to charge point connection:
- LV distribution systems for large-scale charge point installations
- Power distribution boards and sub-distribution
- Containment, cabling, and termination to charge points
- Load management integration
- Testing, commissioning, and handover
How ADDCharge delivers eHGV depot electrification
Grid-scale EV charging infrastructure
EV charging environments demand far more than standard electrical installation. ADDCharge’s engineering teams specialise in high-demand, multi-connection electrical systems, designed to support fast, ultra-rapid, and depot-based charging. We routinely deliver grid connection projects ranging from several hundred kVA to multiple megawatts, supporting commercial electric vehicle charging infrastructure across fleet depots, private charging hubs, retail and commercial car parks, and bus and HGV facilities.
Early-stage engineering support
Because we understand how electrical infrastructure, grid approvals, and civil design interact, we can unlock solutions that standard contractors cannot. We provide early-stage engineering support to de-risk design and capacity constraints before they become programme problems.
One team from excavation to energisation
ADDCharge is not a conventional electrical contractor. Our electrical engineering capability sits alongside our ICP and civil engineering services, allowing us to manage the full electrical interface from excavation to energisation. This removes risk, shortens programmes, and avoids the disconnects that often occur between civils, utilities, and installers.
Standards and credentials
Works are supported by robust testing, commissioning, and handover processes. We deliver full technical documentation, as-built records, and compliance packs to enable adoption and long-term operation.
