Surge Protection Device (SPD) Installation
Green Earth Sussex installs surge protection devices (SPDs) throughout Sussex, safeguarding your property's electrical installation and connected equipment from damaging transient overvoltages. Under the 18th Edition wiring regulations (BS 7671:2018 Amendment 2), SPDs are now required in most new and rewired domestic and commercial installations.
Power surges can be caused by lightning strikes, switching operations on the network, or faults within the supply. Even a brief surge can permanently damage televisions, computers, smart home systems, white goods and other expensive equipment. A properly installed SPD at your consumer unit provides whole-property protection at a fraction of the cost of replacing damaged appliances.
