London & Surrey
Supplementary and main bonding works to ensure your property meets current electrical safety standards across London & Surrey.
Earthing and bonding are fundamental to electrical safety. Earthing provides a safe path for fault current to flow, allowing protective devices to operate and disconnect the supply. Bonding connects metallic parts of the installation (pipes, structural steelwork, etc.) to earth, preventing dangerous voltage differences between them. TW Electrical carries out main protective bonding, supplementary bonding and earthing works across London and Surrey. We frequently identify missing or inadequate bonding during EICR inspections — particularly in older properties in Twickenham, Richmond and Ealing — and can carry out all remedial bonding works to bring your installation up to current standards.
