Frequently Asked Questions
Do I need planning permission for an EV charger?
No, most home EV chargers fall under permitted development rights. Exceptions include listed buildings, conservation areas, and flats. Always check with your local council first.
Can I use any socket instead of a dedicated charger?
You can, but it’s not recommended. Slow charging takes 20+ hours. Dedicated 7kW chargers are faster, safer, and include smart scheduling features.
Is a 7kW charger fast enough?
For 95% of UK drivers, yes. A 7kW charger adds roughly 30 miles of range per hour—enough to fully recharge most EV batteries overnight.
