Old or overloaded wiring can be unsettling, especially when you are responsible for a family home, a rental flat or a busy workplace. If you are searching for full rewire or partial rewire services in London, you want clear advice, safe installation and a reliable contractor who will treat the property with care. First Action provides planned rewiring London projects for renovations and urgent upgrades for ageing systems, with experienced engineers who understand how to keep disruption under control while improving electrical safety.
A house rewire is often needed when a property is extended, converted or modernised, for example during kitchen refurbishments, loft conversions or major layout changes. In these cases, a partial rewire may be enough to serve the new rooms while integrating with existing circuits that are still in good condition.
A full rewire is usually recommended when the installation is very old, has suffered visible damage or fails basic electrical inspection checks. Signs that wiring may be past its best include old cable types, a dated fuse box, frequent tripping, burning smells, discoloured sockets or switches that feel warm. If equipment is around forty years old or more, it is sensible to ask a NICEIC electrician to assess its condition.
Before work starts, an engineer will inspect the property, discuss how you use each room and plan new circuits to match your needs. This may include additional sockets, modern lighting layouts, new cooker supplies and provision for future appliances. During the job, existing cables are removed where practical and replaced with new wiring that meets current standards, along with a modern consumer unit or fuse board replacement where required.
For occupied homes, the team works methodically to keep as much of the property live as possible while sections are upgraded. Dust protection, clear communication and realistic scheduling help keep stress to a minimum. Once work is complete, full electrical testing is carried out and certification is issued so you have written proof that the installation meets current regulations.
Certain features strongly suggest that an installation needs attention. These include:
Cables with black rubber, fabric or lead sheathing
A wooden backed fuse box or mixed old style fuse boxes
Round pin sockets or switches in skirting boards
Braided flex hanging from ceiling roses
Brown or black switches and aged socket fronts
If any of these are present, a professional electrical inspection is highly advisable, even if you have not yet noticed obvious faults. Early checks help prevent shocks, reduce fire risk and plan upgrades before problems become urgent.
First Action has more than two decades of experience delivering commercial rewiring and domestic projects across London. Engineers are fully qualified to current standards and work under NICEIC approval, which means methods, test equipment and paperwork are regularly checked. The team is familiar with everything from compact flats to larger commercial premises and understands how to integrate rewiring with other works such as kitchen fits, bathroom refits and structural alterations.
Alongside rewiring, First Action can support consumer unit upgrade work, landlord electrical safety checks, fault finding and certification for sales or lettings. This combination allows clients to handle inspection, remedial work and sign off through one contractor.
Visible signs such as old cable types, a dated fuse box, frequent tripping or burning smells are strong warnings. An NICEIC electrician can confirm whether a full or partial upgrade is needed after a proper inspection.
In many cases yes, although there will be noise, dust and periods without power in certain rooms. The engineer will agree a plan with you so work areas and live areas are managed sensibly.
A typical three bedroom house usually takes several days, depending on access, floor construction and any other building work taking place. Larger or more complex properties may take longer.
Often it is. New circuits can be installed for the extension while existing circuits are tested and retained if they meet current standards. The engineer will advise after checking the original installation.
Yes. After testing, you will receive documentation confirming that the new installation complies with current regulations. This paperwork is important for insurers, lenders and future buyers.

Whether you are renovating, extending or simply concerned about older wiring, a structured rewiring plan will keep your property safer and better prepared for modern electrical demands.
