Surge protection devices, also known as SPDs, help protect electrical installations from transient overvoltage caused by switching events, supply disturbances and lightning-related surges. Browse Type 2 SPDs, whole house surge protection units, external SPD enclosures and three-phase surge protection devices for domestic, commercial and renewable installations.
Our range includes standalone SPD modules, retrofit surge protection kits and pre-wired enclosure units for consumer units, EV chargers, heat pumps, solar PV systems and distribution boards.
Quick answer: For most UK homes and small commercial installations, a Type 2 surge protection device fitted at the consumer unit is the standard choice for whole house surge protection.
Choose your SPD based on the installation type, supply arrangement and whether you need a module-only device or a complete enclosure kit.

An SPD must be selected for the supply arrangement, installation location and applicable risk assessment. Confirm whether Type 1, Type 2 or combined protection is required, then match the device configuration and ratings to the manufacturer’s design information.
Commonly installed at consumer units and distribution boards to limit transient overvoltage from switching events and indirect lightning effects.
Pre-wired or external enclosures can provide a practical retrofit route where board space is limited or a separate protective assembly is preferred.
Three-phase systems require a suitable multi-pole SPD arrangement coordinated with the supply, earthing system and upstream protection.
