EV Boards with Built-In Surge Protection (SPD)
These EV consumer units are supplied with integrated Type 2 surge protection devices (SPD), providing compliant protection for EV charger circuits under BS 7671 (18th Edition Amendment 2).
Using a dedicated EV board with built-in SPD ensures protection against transient overvoltage and avoids the need to retrofit separate surge modules at the main consumer unit.
Quick answer: EV chargers require surge protection to meet UK wiring regulations. Installing an EV consumer unit with integrated SPD ensures compliance and protects sensitive charger electronics from voltage spikes.

Why Surge Protection Is Required for EV Chargers
EV chargers contain sensitive electronics and operate under sustained high load. Transient overvoltage events can damage internal components and void manufacturer warranties. For this reason, BS 7671 requires surge protection to be considered for all EV installations.
Do EV Chargers Have Built-In Surge Protection?
Some chargers include limited internal suppression, but UK regulations require a dedicated SPD at the supply board. Installing a purpose-built EV consumer unit with integrated surge protection ensures regulatory compliance and long-term reliability.
What’s Included in an EV Surge Protection Board?
- Type 2 Surge Protection Device (SPD)
- Dedicated RCBO or RCD protection
- Optional PME (PEN fault) protection
- Metal or weatherproof enclosure
Choosing the Right Board
- Domestic installs – compact EV boards with SPD + RCBO
- Outdoor chargers – IP65 weatherproof surge-protected units
- PME supplies – integrated PEN fault detection boards
- Higher-capacity systems – scalable connection units with SPD
