Full & Partial Rewires

Rewiring London

Rewiring is the biggest job most homes ever have done electrically, and also one of the easiest to get wrong if it’s scoped badly, either by overpromising a quick partial fix on wiring that genuinely needs replacing throughout, or by recommending a full rewire where a more targeted repair would have done. First Strike Electrical Ltd has carried out full and partial rewires across London properties since 1999, and as an NICEIC approved contractor, every rewire is completed and certified to current wiring regulations, BS 7671.

Assessment

Signs a Property Needs Rewiring

  • Round-pin sockets or visible old rubber or fabric-insulated cable
  • A wire fuse board rather than a modern consumer unit
  • Frequent faults across multiple circuits rather than one isolated issue
  • Cables that are cracked, brittle or show signs of age when inspected
  • A property that hasn’t had any electrical work done in several decades

An EICR is generally the clearest way to establish whether a property genuinely needs rewiring or whether the existing installation, though old, is still sound; see our electrical inspection London page for more detail on that assessment.

Scope

Full Rewire Versus Partial Rewire

A full rewire replaces all the wiring, sockets, switches and the consumer unit throughout the property. A partial rewire targets specific circuits or areas, useful where most of a property’s wiring is sound but a kitchen extension, a converted loft, or one particular circuit needs bringing up to current standards. We’ll assess your property honestly and recommend whichever scope actually reflects what’s needed, not automatically the larger job.

Timing

How Long It Takes and What to Expect

A full rewire on an average London terrace or flat typically takes one to three weeks, depending on the size of the property, how accessible the existing wiring is without extensive disruption to walls and floors, and whether other trades need to follow behind us. Rewires can be done in occupied properties, room by room, though this means living with some disruption and temporary loss of power to areas being worked on; for larger jobs or where it’s practical, working during a vacant period, such as during a move, often makes the job quicker and less disruptive.

Paperwork

Certification

Rewiring is notifiable work under Part P of the Building Regulations. On completion, you’ll receive an Electrical Installation Certificate confirming the work meets current standards, paperwork worth keeping alongside your other property documents, since it’s frequently requested during a future sale or by insurers.

Why us

Why Choose First Strike Electrical

NICEIC approved, so our design and installation work on a job this significant is independently assessed, not just self-certified. Trading in London since 1999, we’ve rewired properties across every era of London housing stock, and we’ll give you a clear, staged quote and realistic timeline before any work starts, not a vague estimate that grows once walls are already opened up.

Worth considering

Making the Most of a Rewire

Because a rewire involves opening up walls and floors anyway, it’s often the most cost-effective point to make other changes you’ve been putting off: adding extra sockets in rooms that never have enough, running cabling for data points or smart home devices, or repositioning switches and lights to suit how you actually use a room rather than where a previous owner happened to put them decades ago. Worth raising any of this at the quoting stage rather than after the walls are closed up again.

Frequently Asked Questions

How do I know if I need a full rewire or just a partial one?

An EICR is the clearest way to establish this. We can also assess your property directly and give you an honest recommendation on scope.

Can I stay in my home during a rewire?

Often, yes, particularly for partial rewires or full rewires done room by room, though it does mean some disruption and temporary loss of power to the areas being worked on.

How long does a full rewire take?

Typically one to three weeks for an average London property, depending on size and accessibility. We’ll give you a realistic estimate for your specific job.

What certification will I receive?

An Electrical Installation Certificate confirming the completed work meets current wiring regulations, which is worth keeping for future reference.

Can I add extra sockets or data cabling while the rewire’s happening?

Yes, and it’s usually the most cost-effective time to do it, since walls are already open. Worth mentioning any extras you want at the quoting stage.
