Our surge protection devices (SPDs) are designed to protect homes and businesses from voltage spikes and transient overvoltages. These spikes can be caused by lightning strikes, switching surges, or faults in the electrical grid — and they can damage your appliances, lighting, and wiring.

We stock both Type 1 and Type 2 surge protection devices. Type 1 SPDs are used at the main incomer to protect against large surges caused by lightning. Type 2 SPDs are more common in consumer units and distribution boards, where they guard against switching spikes and indirect surges.

Our SPDs are suitable for single-phase and three-phase systems. They are fast-acting, compact, and easy to install in new or existing electrical setups. You can fit them inside consumer units or mount them externally using a compatible enclosure.

All devices meet UK regulations and are tested for safety and performance. Whether you’re protecting a domestic circuit or an industrial board, our surge protection range ensures your system stays safe and compliant.

    Delivery Policy
    Free Next-Day Delivery Over £75 + VAT:
    Orders above £75 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £150 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £150 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.
    Dispatch Times
    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
