Surge Protective Devices for Electrical Installations

A surge protective device limits transient overvoltages and diverts surge current away from connected equipment. SPDs are used as part of a coordinated electrical protection strategy and may be required depending on the installation type, risk assessment and applicable BS 7671 requirements.

Type 1, Type 2 and Combined Type 1+2 SPDs

Type 1 SPDs are designed for locations where partial lightning current may need to be discharged, typically at the origin of installations where this level of protection is required. Type 2 SPDs are widely used to protect against switching surges and transient overvoltages associated with indirect lightning effects. Combined Type 1+2 devices provide both functions in one unit where appropriate.

Single-Phase, Three-Phase and Solar PV Surge Protection

The range includes surge protection for single-phase and three-phase AC installations, together with dedicated DC SPDs for solar PV systems. Choose a device that matches the system voltage, number of poles, earthing arrangement and application. Dedicated category ranges make it easier to compare suitable options for consumer units, distribution boards and PV installations.

Choosing the Correct Surge Protective Device

  • Check whether Type 1, Type 2 or combined Type 1+2 protection is required.
  • Match the SPD to the supply voltage, AC or DC system and number of poles.
  • Confirm compatibility with the installation’s earthing arrangement.
  • Check discharge ratings, backup protection and coordination requirements.
  • Follow the manufacturer’s installation instructions and applicable BS 7671 requirements.

SPD Kits and Trusted Electrical Brands

Alongside stand-alone SPDs, we stock consumer unit SPD kits, enclosure solutions and surge protection combinations from brands including FuseBox, Hager, Live Electrical, Niglon, WCED Whitecliffe and Citel. Use the product filters and subcategory links above to narrow the range quickly.

For trade and professional installations, our Surge Protective Devices range gives you practical options across domestic, commercial and solar PV applications, with fast UK delivery available on eligible in-stock orders.

Next Day Delivery

Cut-Off Time and Order Information
To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

In Stock Delivery Policy

Free Next-Day Delivery Over £100 + VAT:
Orders above £100 + 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 £200 + 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 £200 + 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.

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
