Older cables, accessories and connections can deteriorate behind walls, ceilings and electrical fittings. Previous additions may also have changed the original installation.
Age and use
Heat, movement, moisture and regular use can gradually affect cables and accessories.
Extensions and equipment
Extensions, conversions and fixed equipment can add demand to circuits designed for an earlier layout.
Previous alterations
Poorly completed or undocumented alterations may leave unsuitable wiring or protection.
Where deterioration affects several circuits, an
electrical rewiring assessment
can establish whether targeted repair or wider replacement is appropriate.
