Our Surge Protection Devices SPDs collection brings together a practical range of devices designed to help protect electrical installations from transient overvoltages. Suitable for domestic, commercial and light industrial settings, these surge protectors are commonly fitted within consumer units or distribution boards to reduce the risk of damage caused by power surges and switching events.

You will find SPDs suited to everyday installation work, making them a standard consideration for trade electricians, installers and knowledgeable DIYers. Whether you are working on a new install or updating an existing board, surge protection devices support safer electrical systems by managing voltage spikes before they reach connected equipment.

Surge protection is often specified for homes with sensitive electronics, offices running IT equipment, and commercial buildings where continuity matters. SPDs are also relevant in properties prone to lightning activity, supply fluctuations or frequent switching loads, helping to reduce the likelihood of nuisance faults and unexpected equipment failure.

When choosing an SPD, it is important to consider the type required for the installation, the supply arrangement, and where it will be fitted within the system. Installers will also check compatibility with the existing consumer unit or distribution board, along with the intended application, to ensure the correct level of protection is provided.

The products in this collection are selected for use in UK electrical systems and align with current installation practices. If you are matching an SPD to a specific board or upgrading protection as part of other electrical works, reviewing the product specifications carefully will help ensure a suitable choice for the job.
