Looking for an EV Charger? 10 Things We Learned From Our Latest Bournemouth Install

Our team recently completed the installation of a 7kW tethered EV charging point for a resident in the Winton area of Bournemouth. The project was commissioned for a new BMW i4 and required a comprehensive electrical assessment of the property's existing infrastructure. A 20-metre cable run was executed, necessitating the lifting and reinstatement of block paving along the driveway to maintain the aesthetic of the high-end exterior.

The existing distribution board lacked the necessary spare ways and RCD protection required by BS 7671 18th Edition regulations. We performed a full consumer unit upgrade, replacing the aged fuse box with a modern unit featuring dedicated RCBO protection for the EV circuit. This ensured the 32A load could be handled safely without compromising the property's internal circuits.

Technical observations from this Bournemouth installation include the following:

• Initial load calculations are mandatory to prevent overloading the 60A main service fuse.
• DNO notification must be submitted immediately post-installation for grid monitoring.
• Trenching depth for SWA cable under driveways must adhere to strict safety depths.
• Earthing arrangements (TT vs TN-C-S) determine if an additional earth rod or an O-PEN protection device is required.
• Physical positioning of the charger should be between 750mm and 1200mm from ground level.
• Wi-Fi signal strength at the mounting point is critical for smart-charging functionality and firmware updates.
• Load balancing features should be prioritised if the property operates high-draw appliances like electric showers.
• Cable management systems must be robust to withstand coastal weather conditions in Dorset.
• Correct labelling of the new circuit in the consumer unit is a regulatory requirement.
• Final testing and commissioning must include an RCD trip test specifically for DC leakage.
