Available in IP40 indoor boards or IP65 weatherproof enclosures, these boards are ideal for both single-EV chargers and multi-point installations. Options include PME-compliant designs that avoid the need for a separate earth rod, plus hybrid variants compatible with heat pump circuits, solar PV, and three-phase systems.
- Pre-wired & tested – cuts install time on site
- PME fault protection available – ready for EV regulations
- SPD as standard – required under BS 7671 for EV circuits
- Scalable – from domestic wallbox installs to commercial multi-bay setups

EV Surge Protection Explained
EV chargers draw high loads and are sensitive to transient overvoltage. That’s why the 18th Edition wiring regulations make surge protection a requirement for EV installations. Without an SPD, voltage spikes from the grid or nearby lightning strikes can damage the charger and connected electronics.
Do EV Chargers Already Have Built-In Surge Protection?
Some EV chargers include limited surge suppression, but BS 7671 requires a dedicated SPD at the supply board. Using a compliant EV consumer unit ensures you meet regulations and keep the installation covered by manufacturer and insurance warranties.
Choosing the Right EV Distribution Board
- Domestic installs – compact boards like the 4-Way EV Protection Unit with SPD + RCBO.
- Commercial bays – larger capacity options such as the IP65 EV Connection Unit with Surge Protection.
- Outdoor installs – weatherproof boards including the 8-Way IP65 EV Connection Unit.
- PME supplies – boards with built-in PEN fault detection like the IP65 PME Fault Detection Unit, no earth rod required.
Trust & Compliance
All our EV surge protection boards are UK tested, BS EN certified, and shipped from stock with next-day delivery options. Each unit comes pre-wired to save time on site and includes full manufacturer warranty support. Returns are covered under our returns policy.
FAQs
Do I always need a Type B RCD for EV chargers?
Not always – most chargers are compatible with Type A RCDs, but certain models with DC leakage require Type B. Always check manufacturer guidance.
Can I use these boards with solar or hybrid systems?
Yes – many of our EV surge boards are designed to integrate with solar PV SPDs and heat pump boards, giving future-proof flexibility.
What’s the difference between an EV board and a standard consumer unit?
An EV-ready board is pre-fitted with the protection devices required under BS 7671: SPD, RCD/RCBO, and (where needed) PME fault detection.
