If your property still has old wiring, an outdated fuse box, or keeps tripping breakers, a full or partial rewire brings it up to current safety standards. Wesparx carries out house rewiring across Sutton, Surrey and South London, quoted as a fixed price and completed to 18th Edition wiring regulations.
Full Rewire vs. Partial Rewire
Full rewire — replaces all the wiring in a property: sockets, lighting, switches, and the consumer unit. Typically needed in homes wired before 1970, or where the existing wiring is rubber or fabric insulated.
Partial rewire — replaces wiring in specific rooms or circuits, often used for extensions, single-room renovations, or fixing a specific problem area without disturbing the rest of the property.
We’ll assess your property and recommend whichever genuinely matches what’s needed — not automatically the bigger, more expensive job.
Signs Your Property Might Need Rewiring
Wiring installed before 1970, or you’re not sure when it was last done
Round-pin sockets or a mix of socket types around the property
A consumer unit with a wooden backboard, cast iron switches, or ceramic rewireable fuses
Frequent tripping, blown fuses, or circuits that can’t handle multiple appliances
Scorch marks around sockets, warm switch plates, or a burning smell
We’ve written a more detailed breakdown of these warning signs on our blog if you want to check further before booking an assessment.
What a Rewire Typically Costs
Full rewire costs in the UK generally range from around £3,000 for a small one-bedroom flat up to £12,000+ for a large five-bedroom home, with most standard three-bedroom properties falling somewhere between £4,500 and £8,000. The exact price depends on the size of the property, ease of access under floors and in walls, and whether redecoration is needed afterwards. We’ll always give you a fixed price after seeing the property, not a generic estimate.
What’s Included
Removal of old wiring and installation of new cabling throughout the affected areas
New consumer unit with RCD/RCBO protection, if not recently upgraded
Testing and certification of the completed installation
Making good of chased walls and floors where access was needed (redecoration itself is typically not included, but we’ll be clear about what is upfront)
Certification
Every rewire — full or partial — is tested and certificated on completion. You’ll receive an Electrical Installation Certificate confirming the work meets current regulations, useful for insurance, mortgage applications, and peace of mind.
