This is an important safety question, and it is exactly what we assess during our free survey.
What we check:
- Main fuse rating — your incoming supply fuse (typically 60A, 80A, or 100A) determines how much power your home can draw in total. A 7 kW charger draws up to 32A, which is significant.
- Consumer unit condition — we check whether your board has spare capacity and meets current safety standards
- Cable routing — we assess the distance from your consumer unit to the charger location and determine the correct cable size
- Existing electrical load — we consider what else is drawing power in your home (electric shower, cooker, immersion heater) to ensure the total load is within safe limits
Safety measures we always include:
- Dedicated circuit — every EV charger we install gets its own dedicated, protected circuit from the consumer unit. It is never shared with other appliances.
- Load management — smart chargers can automatically reduce their power draw when your home’s total demand is high, protecting your main fuse
- Earth rod — installed where required by regulations for additional safety
If any upgrades are needed, we include them in your quote upfront. There are no surprises.
