REWIRING HOMES AND BUSINESSES ACROSS DERBYSHIRE

Rewiring Services Derby

Electrical wiring has a finite lifespan, and properties built before the 1980s in particular are likely to have wiring that no longer meets modern safety standards or the electrical demands of contemporary living. A full or partial rewire brings your property up to current BS 7671 standards, reduces the risk of electrical faults, and makes your system fit for the additions modern households need — EV chargers, smart home systems, and high-load appliances included.


At Derbyshire Electrical Specialists, our NAPIT-registered electricians carry out full and partial rewires for homes and commercial properties across Derby and Derbyshire. Every rewiring project begins with an Electrical Installation Condition Report (EICR) to assess the existing system accurately before any work is planned.

The age of your property gives a useful indication of what type of wiring may be present:


Rubber-Insulated Cables (pre-1960s):

  • Found in very old homes, these use rubber for insulation, which becomes brittle over time.
  • Risk: Cracks and exposes live wires, increasing fire and shock risk.

Lead-Sheathed Cables (1920s–1950s):

  • These cables have a lead outer sheath.
  • Risk: Lead exposure hazard and poor earthing compared to modern standards.

Tinned Copper with Rubber (TRS):

  • A transitional type used in mid-20th century.
  • Risk: Same degradation issues due to rubber insulation.

PVC Wiring without Earth (1950s–1960s):

  • Early versions of PVC twin-core cable often had no earth wire.
  • Risk: Unsafe for use with metal light switches and fittings, violating modern safety standards.


Most of these will be connected to Old Fuse Boxes (Rewireable fuses):

  • Typically fitted with fuse wire rather than modern circuit breakers.
  • Risk: Slow to respond to faults, increasing fire risk and lacking RCD (residual current device) protection.

The tests we carry out will allow us to advise on the stated of your wiring in terms of safety and also in terms of any limitations it may currently provide in terms of what type of appliances or number of appliances can be connected safely in the future and what the likely scenarios will be if you do not upgrade your fuse box and wiring.

House Rewiring Derby

Before starting any rewiring project, our electricians carry out an Electrical Installation Condition Report (EICR) to establish the exact condition of the existing wiring.. The purpose of this is to evaluate the condition of the existing wiring. If issues like outdated materials (e.g., lead, rubber, or aluminium wiring), damaged insulation, or overloaded circuits are detected, a full or partial rewire may be required to ensure your home is safe and electrical performance is not compromised.

Once rewiring has been agreed the next step is to remove the existing electrical wiring. For a complete house rewire this will involve accessing walls, ceilings, and floors to extract old cables. Whilst we try to be as careful as possible there will be mess and damage to walls and potentially floors and ceilings depending on how the old wire has been run and connected through the building. We take care to avoid damaging any structural aspects of the house and this is unlikely to happen but there will be cosmetic damage. This is why many house rewiring projects are taken on board when following a house purchase of an alder property. If done as one of the first jobs then patching up afterwards form part of the decoration process and avoids having to re-do cosmetic touching up in the future.

With a full house rewire cables, new sockets, switches, and consumer units (fuse boxes) are installed. Current wiring standards will include:

  • Ring circuits for sockets
  • Lighting circuits with earth protection
  • Dedicated circuits for high-energy appliances like ovens and electric showers

Your outdated fuse box will be replaced with a modern consumer unit fitted with Residual Current Devices (RCDs) and Miniature Circuit Breakers (MCBs), ensuring greater protection against electrical faults.

Once the rewiring is complete, our electrician performs a number of safety tests to ensure everything functions correctly. A certificate, such as an Electrical Installation Certificate (EIC), will be issued to confirm compliance with UK wiring regulations (BS 7671).

Full Rewires 

During a full rewiring process, power will need to be turned off for several days or even a couple of weeks, depending on the scale of the project.

This can be disruptive, requiring temporary heat and lighting solutions or even alternative accommodation.

The process will create a lot of dust so please ensure that if you are leaving items in your house there are properly covered. It is likely that you will be decorating afterwards so the effort will not be wasted.

It is worth having a discussion about you plans following rewiring as our electricians can back fill the chases in the walls created by replacing wires. This can be an additional time consuming process waiting for plaster to dry and reapplying after shrinkage. If you are having your walls replastered anyway as part of your decoration and renovation process then our electrician will be able to save time, and there therefore save you money, if the final flush wall  finishing is done by the pasterer.

LOCAL REWIRING SPECIALISTS

Based in Derby, we bring our rewiring service to you — covering the whole of Derbyshire.

Commercial Rewiring Derby

Commercial rewiring differs from residential work in scale, regulatory requirements, and operational complexity. Offices, warehouses, retail units, and industrial premises have higher electrical loads, more circuits, and in many cases three-phase power supplies that require specialist knowledge to work on safely.


Key compliance requirements for commercial electrical work include the Health and Safety at Work Act, the Electricity at Work Regulations 1989, and fire safety legislation — all of which our NAPIT-registered electricians are fully experienced in working to.


Common commercial rewiring projects we carry out in Derby include:


  • Office rewiring and circuit upgrades for new equipment
  • Warehouse and industrial unit rewiring
  • Emergency lighting and fire alarm system integration
  • Retail unit electrical refurbishment
  • Commercial EV fleet charging infrastructure


We work with businesses across Derby and Derbyshire, scheduling work outside operating hours where required to minimise disruption to your business.

Office Rewires Derby

Office rewiring requires more planning than domestic work — the need to maintain business continuity throughout the project means phased installation, out-of-hours working, and careful co-ordination with your IT and facilities teams.


We carry out office rewiring projects across Derby, working around your operational requirements to deliver compliant, certified electrical systems with minimum downtime. Modern office rewiring typically includes:


  • Upgraded circuits to support current and planned equipment loads
  • Energy-efficient lighting systems replacing older fluorescent installations
  • Surge protection for IT infrastructure
  • Smart building controls including automated lighting and occupancy sensors
  • Fire-resistant cabling and updated [alarm and fire systems](/alarm-security-cctv-installation) where required


Speak to us about your office or commercial rewiring requirement and we'll carry out a site assessment before providing a detailed, phased project plan.

MOST COMMON REWIRING QUESTIONS:

  • Can any electrician carry out a house rewiring in Derby?

    No. Rewiring is notifiable work under Part P of the Building Regulations and must be carried out by an electrician registered with a government-approved competent person scheme.

    Our electricians are NAPIT-registered with over 20 years' experience, which means all rewiring work we carry out is self-certified — we issue the Electrical Installation Certificate (EIC) directly and notify building control on your behalf. You don't need to arrange a separate building control inspection.

  • How do I know my house needs rewiring?

    Knowing when to rewire a house is essential for maintaining electrical safety. While there is no strict lifespan for electrical wiring, several indicators suggest it might be time for an upgrade.


    1. Age of the Wiring

    Homes wired before the 1980s may still have outdated systems that do not comply with modern safety standards.

    Properties with rubber, lead, or fabric-insulated wiring are at high risk of deterioration and fire hazards.

    2. Frequent Electrical Issues

    Flickering lights, tripping breakers, and frequent blown fuses indicate an overloaded or faulty system.

    Burning smells or discoloured sockets suggest overheating or electrical arcing.

    3. Lack of Modern Safety Features

    Absence of RCDs: Modern consumer units have RCDs that protect against electric shocks.

    Two-pronged sockets: Older wiring may not have proper earthing, increasing the risk of electric shocks.

    4. Home Renovations and Increased Electrical Demand

    If you are planning major home renovations or installing high-power appliances, rewiring may be necessary to handle the additional load.

    Smart home systems, electric vehicle chargers, and underfloor heating often require electrical upgrades.

    5. Compliance with New Regulations

    Electrical safety regulations evolve over time. If a property hasn’t been inspected for decades, a professional assessment is advisable - especially if you are looking to sell your home soon.


    If you're unsure, the most reliable approach is to book an [EICR](/electrical-inspections) — this gives you a definitive assessment of your wiring's condition and any action required.
