How much does a full home rewire cost in London with BSAG Electrical?
At BSAG Electrical in London (EC1V 2NX), the cost of a complete house rewire depends on property size, age, and complexity.

We provide a free on-site survey and transparent quote so you know exactly what your rewiring will cost.

Absolutely — BSAG Electrical are registered with NAPIT and fully compliant with UK regulations (BS 7671, Part P etc). We hold the necessary insurance, provide certification after each job, and always follow safe installation and testing procedures.
04
What additional electrical services does BSAG Electrical offer in London besides fault-finding and rewiring?
In addition to fault-finding and full or partial rewires, BSAG Electrical covers: additional socket installations, consumer unit upgrades/replacements, LED lighting design & installation, home automation systems, electrical safety reports (EICR) for landlords, and more — all across London.
05
How do I know if my London home needs rewiring or electrical safety testing?
Signs your property may require rewiring or an Electrical Installation Condition Report (EICR) include frequent circuit trips, buzzing or discoloured sockets, old wiring (pre-1960s lead or fabric insulation), or if you’re a landlord needing compliance documentation. In London, older buildings especially benefit from a professional inspection.
