Surge Protective Devices (SPDs) for Consumer Units & Distribution Boards

Protect electrical installations from transient overvoltages caused by lightning activity and switching surges with our range of Surge Protective Devices (SPDs). This category includes SPDs and kits suited to both domestic consumer units and commercial distribution boards, with options designed to meet BS 7671 expectations.

 

Type 1, Type 2 & Combined Type 1+2 Surge Protection

Choose Type 1 SPDs for installations where direct lightning currents may be present at the origin, Type 2 SPDs for protection against switching and residual surges, and combined Type 1+2 devices commonly used in consumer units. Where multiple devices are used, they should be properly coordinated for correct operation.

 

Single Phase, Three Phase & Solar PV DC SPDs

Shop by application with dedicated ranges for Consumer Unit SPDs, Single Phase SPDs, Three Phase SPDs, and SPD Surge Protection for Solar PV. You’ll also find practical all-in-one options such as SPD kits, stand-alone enclosures, and meter supply isolators with surge protection.

 

Filter by Earthing System, Poles, IP Rating & Features

Use the filters to match your install quickly — including SPDs for TN-S, TN-C-S, TT, and IT systems, plus choices by number of poles (1P/2P/3P/4P), IP rating (e.g. IP20/IP55), and extras like LED indication, data/telephone protection, and enclosure options.

 

Trusted Brands & Fast UK Delivery

Choose from well-known names including FuseBox, Hager, Live Electrical, Niglon, WCED, and specialist ranges such as Citel options for DC applications. UK Mainland orders over £100 + VAT qualify for free standard next-day delivery, with a 3pm cut-off for in-stock items (subject to availability). You also benefit from a 30-day returns policy on eligible unused goods (check product notes for exclusions).

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.

Supplier Lead Time & Availability

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.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.
