EV Charger Installation with Consumer Unit Upgrade
1The Challenge
The customer had just purchased a new electric vehicle but their existing consumer unit was an older split-load board with no spare capacity. The garage was 15 metres from the house, requiring a substantial cable run.
2Our Solution
We upgraded the consumer unit to a modern 12-way RCBO board, providing capacity for the EV charger and future-proofing the property. We installed armoured cable from the house to the garage, terminating at an Ohme Home Pro smart charger. The charger was set up with the Ohme app for scheduled charging during off-peak hours.
3Results Delivered
- Ohme Home Pro 7.4kW charger installed
- Consumer unit upgraded to 12-way RCBO
- 15m armoured cable run professionally installed
- Smart charging configured for off-peak rates
- Full OZEV grant applied (£350 saving)
"From quote to installation, the whole process was seamless. The Ohme charger works brilliantly and the app is really intuitive. Very impressed."
On-Site Observations
What we found during the job:
- The existing split-load board was a common 2015-era design with only 2 spare ways
- Ground conditions were rocky - SWA was run above ground level with UV-resistant clips
- WiFi signal in the garage was poor so we tested the Ohme app before leaving
Electrician's Note:
"Always test the charger app connectivity before sign-off. Nothing worse than a callback because the customer can't connect to their charger."
— Shaye Grant, Lead Electrician
Professional Insight:
15m runs are common in Devon properties. We now recommend customers consider their charging location during the quote stage to avoid surprises.
