What affects rewiring costs in London?
The cost of rewiring a house in London depends primarily on property size, the complexity of the existing installation, and how accessible the wiring is. Older properties with solid walls (rather than stud partition walls) are harder to channel cable through and cost more to rewire. The number of circuits, sockets, lights, and consumer unit size all contribute to the total. Most electricians quote rewires on a per-property basis after a site visit. All rewiring work must be carried out by a Part P registered electrician and signed off with a certificate. Use Quote2 to reach certified local electricians in London.
