—Safety and decisions

Outdoor electrical safety

Gardens and terraces combine water, sun and digging. Electricity outdoors needs extra care.

Outdoor areas see garden tools, pressure washers, outdoor kitchens, lighting and pool equipment. Water from irrigation and cleaning, damage from digging and UV degradation all increase risk. Using outdoor-rated equipment, RCD protection and proper sockets reduces it.

Safety and decision guides are advice for the reader. They describe practice, not a service level.

Indoor extension leads trailed outside, cables run across lawns and equipment left in the rain are common hazards. Outdoor sockets and protected cable routes are safer long-term solutions.

  • RCD protection

    Essential outdoors.

  • Protect cables
