Full House Rewire — 1930s Three-Bed Semi in Swanley
A complete rewire of an occupied 1930s three-bedroom semi-detached house — original rubber-insulated wiring replaced throughout, a new 14-circuit consumer unit installed, and the whole property re-certified to BS 7671, completed in eight working days.
The problem
The homeowners had just purchased the property, and the pre-purchase EICR told a familiar story for a 1930s house: original rubber-insulated cabling still live in the lighting circuits, a rewireable fuse board with no RCD protection, and decades of piecemeal additions — spurs off spurs, junction boxes buried in voids, and a kitchen running on a single overloaded ring.
The report returned multiple C2 (potentially dangerous) codes and a C1 for exposed live conductors found in the loft. With a renovation planned anyway, a full rewire was the only sensible answer — and it needed to happen before the plasterers and decorators arrived.
Our approach
We surveyed the property room by room and designed a new 14-circuit installation around how the family would actually use the house: dedicated circuits for the kitchen appliances, a separate circuit for the home office, outdoor power front and rear, and wiring provision for a future EV charger.
The rewire was programmed floor by floor over eight working days. First fix — new cabling run through floors, walls and the loft — was completed with the family living in the property, keeping power live to essential areas each evening. Chases were cut cleanly and agreed with the plasterer's schedule so making-good happened once, not twice.
Second fix followed: over sixty new sockets and switches, LED downlights in the kitchen and bathroom, and a new all-metal consumer unit with dual RCD protection and surge protection, relocated from the under-stairs cupboard to an accessible position in the hallway.
The Result
The completed installation was inspected, tested and certified with a full Electrical Installation Certificate, and the paperwork lodged through our NAPIT registration — so Building Control notification was handled without the owners lifting a finger.
The family moved through their renovation on schedule, and the new EICR — the same inspection type that flagged the original dangers — now reads a clean 'Satisfactory' for the next five years.
