EV Charger Installation —Designed & Installed Properly
A compliance-led approach to EV charging, focused on safety, system integrity, and long-term reliability.
Installation, assessment, and design carried out in accordance with current regulations and best practice.
Electric vehicle charging is not simply the addition of a new circuit — it is the integration of a high-load device into an existing electrical system.
At Volthammer Electrical, EV installations are approached in the same way as all our work: methodically, with full consideration given to safety, compliance, and the condition of the existing installation.
Why EV Installations Require Careful Design
EV chargers place sustained demand on an electrical installation and must be correctly integrated to ensure safe operation. Key considerations include:
-
Supply capacity and load assessment
-
Suitability of the existing consumer unit
-
Earthing arrangement (TN-C-S / TT / PME considerations)
-
Protection against open PEN conductor faults
-
Correct RCD / RCBO selection
-
Cable sizing, routing, and mechanical protection
-
Coordination with other high-load equipment (showers, cookers, heat pumps)
These are not assumptions — they are verified before any installation proceeds.
EV Installation Assessment
Before any installation, we carry out a structured assessment to determine suitability and design requirements.
What’s included:
​
-
Verification of earthing system and bonding
-
Incoming supply capacity review
-
Consumer unit configuration and spare capacity
-
Load calculation and diversity assessment
-
Cable route planning and installation method
-
Consideration for future upgrades (solar PV, battery storage)
This ensures the installation is not only compliant, but appropriate for long-term use.
Installation Approach
EV chargers are installed with the same attention to detail applied across all Volthammer Electrical work.
Clean, surface-mounted or concealed cable routes where appropriate
Correct containment (conduit, trunking, or clipped direct)
Minimal disruption to existing installation
Full testing, certification, and documentation
Clear client handover and operational guidance
-
Ohme
-
Hypervolt
-
Wallbox
-
Anderson
-
Other compatible systems upon request
Charger selection can be discussed during the assessment phase to ensure suitability for your property and usage.
Charger Types and Compatibility
Installations can be carried out for a range of OZEV-compliant and smart charging units, including:
A Measured Approach
EV charging technology continues to evolve. Rather than taking a volume-based approach, installations are undertaken where the system can be properly assessed, designed, and installed to a high standard.
​
This ensures each installation is safe, compliant, and built to integrate with future electrical demands.
Initial EV Installation Programme
We are currently undertaking a limited number of EV charger installations as part of our structured rollout of EV services.
