SPD (Surge Protection Device)

Retrofit Surge Protection Device (SPD) Upgrade for Existing Consumer Unit (Supply & Installation)

Key Features

• BS 7671 Regulation Compliance: Satisfies mandatory surge protection requirements for new EV charger supply circuits.
• Type 2 Transient Overvoltage Protection: Clamps high-voltage spikes caused by grid switching or indirect lightning strikes before they reach your vehicle or household electronics.
• Visual Status Indicator: Features clear window status indicators (Green = Protected, Red = Replaceable Module Expired) for easy visual checking.
• Preserves Existing Board: A cost-effective retrofit solution that avoids the labor and expense of a full consumer unit replacement when your main board is in good working order.
• Dedicated Overcurrent Backup: Fitted alongside a manufacturer-approved MCB to ensure complete safety and isolation within your existing busbar layout.

Standard Supply & Installation Package

• Compatibility Check & Retrofit: On-site verification of busbar layout and direct installation of a compatible SPD module into your current board.
• 50-Mile Local Radius: Installed by certified electricians as part of your EV charger fitting within 50 miles of Peterborough.
• Full Testing & Certification: Verified on-site and documented on your job’s Electrical Installation Certificate (EIC).
• Unforeseen Board Limitations: If upon opening your existing consumer unit we discover physical busbar incompatibility, obsolete internal components, or insufficient space, a secondary enclosure or full board upgrade may be required.

When Is This Required?

1. Your existing metal consumer unit has spare usable ways and is compatible with modern SPD modules.
2. Your current board is otherwise fully compliant, up to date, and in good condition.
3. You want the most cost-effective way to meet EV circuit regulations while keeping your current main fuse board.
