Why Rewire a Property? 

Rewiring may seem like a big job, but in many cases it’s essential. Old wiring not only poses safety risks, it can also limit your ability to use modern appliances and technology. By rewiring your home or business, you benefit from: 

  • Improved safety – reduces the risk of electrical faults and fire hazards
  • Compliance – ensures your installation meets current UK wiring regulations (BS 7671)
  • Modern capacity – supports high-energy appliances, EV chargers, and new technology
  • Increased property value – buyers are more confident when electrics are up to date
  • Peace of mind – reliable electrics designed to handle your daily needs

Signs You May Need Rewiring 

  • Frequent tripping circuits or blown fuses
  • Flickering lights or burning smells from sockets
  • Sockets or switches that feel warm to the touch
  • Old rubber, lead, or fabric-coated wiring
  • Outdated fuse boards without RCD protection
  • No Earth cable present in your wiring system

If you’re unsure, our electricians can carry out an inspection and provide honest advice on whether a full or partial rewire is necessary.

Full vs Partial Rewiring 

  • Full rewiring – renews the electrical installation throughout the property to an agreed scope, including circuits and accessories, with a consumer unit replacement where required. Often considered during major renovations.
  • Partial Rewiring – focuses on specific areas of the property that need upgrading, such as kitchens, extensions, or areas with faulty wiring. Ideal for targeted improvements without replacing everything.

Our Process 

  1. Initial inspection, followed by planning socket positions, lighting, appliance supplies and cable routes
  2. Advice on full or partial rewiring, with a quotation based on property size, circuit count, access and the agreed specification
  3. Safe removal of old wiring and installation of new circuits
  4. Replacement of sockets, switches and consumer units if required
  5. Full testing and certification for compliance and peace of mind

We discuss access, power interruptions and the work programme before starting. Rewiring may involve lifting floors or opening walls; agree responsibility for plastering and decoration as part of the quotation. New circuits are tested and the applicable electrical certification is provided.

Frequently asked questions

How do I know whether I need a full or partial rewire?

The condition and layout of the existing installation need assessing. The property’s age alone does not establish the scope; explain any faults and your renovation plans.

Can I stay in the house during a rewire?

This depends on the scope and working arrangements. Expect disruption and power interruptions, and agree room access and any temporary arrangements before starting.

What changes the price of a rewire?

Circuit and accessory quantities, cable access, fittings and finishing work all influence the quote. Read our rewire planning guide for a practical checklist.
