House Rewiring Services in London
If your London property was built before the 1980s and still has its original wiring, it may not meet current safety standards. A full or partial rewire brings your home up to 18th Edition BS 7671 regulations, eliminates fire risks from deteriorating cables, and gives you a modern electrical installation that will last for decades.
F & A Electrical carries out full and partial rewires across all London boroughs. NIC-EIC accredited with a 9.69/10 Checkatrade rating.
Signs Your London Home Needs Rewiring
Old Fuse Board
If your property has a fuse box with rewirable fuses or an old-style consumer unit without RCD protection, the wiring behind it is likely outdated too. We frequently see this in Victorian terraces across Islington, Hackney, and Camden.
Rubber or Lead Cables
Pre-1960s properties often have rubber-insulated or lead-sheathed cables that become brittle and dangerous with age. Common in period properties across North and Central London.
Burning Smells or Scorch Marks
Any burning smell near sockets or switches, or brown marks on faceplates, indicates overheating wiring that needs urgent attention.
Frequent Tripping
Circuits that trip regularly suggest overloaded or deteriorating wiring. This is especially common in older London flats where the original installation was not designed for modern electrical demands.
What Does a Full Rewire Include?
A full house rewire replaces every metre of fixed electrical cable in your property. We remove all old wiring and install new twin-and-earth cables throughout, along with a brand new consumer unit with RCD protection, new socket outlets and switches, new light fittings and ceiling roses, and upgraded earthing and bonding. Every circuit is designed, installed, and tested to current 18th Edition standards.
We also handle first-fix and second-fix wiring for extensions, loft conversions, and kitchen refurbishments. If you are having building work done, this is the ideal time to rewire.

How Long Does a Rewire Take?
A typical three-bedroom London house takes four to five working days for a full rewire. Two-bedroom flats are usually completed in three days. We work room by room, lifting floorboards and chasing walls as needed, and we always make good after ourselves. In most cases you can stay in the property during the work.
