A house rewire is the most thorough electrical upgrade available — replacing all cabling, accessories and the consumer unit throughout the property in a single coordinated project. It addresses deteriorated wiring, inadequate earthing, non-compliant installations and insufficient circuit capacity in one programme rather than treating individual faults in isolation. For properties where the wiring has reached the end of its serviceable life, a rewire is the correct and most cost-effective long-term solution.
At Chelmsford Electrical, we carry out full and partial house rewires across Chelmsford and the surrounding mid-Essex area. We are registered with a government-approved competent person scheme, which means every rewire we complete is self-certified and notified to building control on your behalf — no separate process required from you.
Chelmsford’s housing stock spans a wide range of construction eras. The Victorian and Edwardian terraces of the town centre and Moulsham Street corridor, the inter-war semis of Galleywood and Springfield, the post-war estates across Chelmer Village and Boreham, and the newer developments around Beaulieu Park all present different wiring characteristics and different rewire considerations. We have worked across all of it and bring the right approach to each property type. Get in touch to discuss what your installation needs.
The most common triggers for a rewire across Chelmsford’s residential stock are a failed EICR, a surveyor’s report on a recent property purchase flagging the wiring as a concern, or visible signs that the installation is aging — rubber-insulated cables in the consumer unit, round-pin sockets, a rewireable fuse board, or wiring that runs in metal conduit throughout the property. Properties built before 1970 that have never been rewired are approaching or exceeding the point at which a rewire should be considered. An EICR is the most reliable way to establish the actual condition of an installation — and we recommend one as a starting point on any property where the wiring history is unclear before committing to a full rewire programme.
A full rewire replaces every cable, socket, switch, light fitting position and the consumer unit throughout the property. It is carried out in two stages — first fix and second fix — with plastering, decoration and floor reinstatement typically happening between the two. First fix involves running new cables to every circuit throughout the building — through floor voids, ceiling spaces and chased into walls where surface routing is not acceptable. Second fix connects accessories, fits the new consumer unit and carries out the full test sequence. The property is without power for parts of the first fix stage. For most Chelmsford properties, a full rewire takes between five and ten working days on site depending on size and complexity.
Not every property requires a full rewire. Where an EICR identifies specific circuits or areas of the installation as deficient while the remainder is in satisfactory condition, a partial rewire — replacing the affected circuits and upgrading the consumer unit — may be the appropriate course of action. This is more common in Chelmsford’s post-war housing stock where the installation has been partially updated at various points and only certain sections remain non-compliant. We carry out partial rewires and targeted circuit replacements across Chelmsford, always assessing the whole installation before recommending the scope rather than defaulting to a full rewire where a targeted approach will resolve the identified deficiencies.
A whole-house renovation is the most practical time to carry out a rewire — when walls are being opened, floors are being lifted and the building is in a state of controlled disruption anyway. Combining a rewire with a renovation programme avoids the additional disruption of carrying out the two projects separately and allows the new cabling to be routed correctly before finishes are applied. For homeowners across Chelmsford and the surrounding mid-Essex area who are renovating a recently purchased property before moving in, planning the rewire as part of the renovation programme from the outset is consistently the most efficient and cost-effective approach. We work alongside builders and renovation contractors to sequence the electrical work correctly within the wider programme.
A house rewire carried out by a registered electrician who assesses the installation thoroughly, plans the cable routes carefully and carries out the full test sequence on completion is a building that is safe, compliant and properly documented. A rewire carried out to a lower standard leaves problems that are difficult and expensive to identify and resolve after the fact.
We are registered with a government-approved competent person scheme, carry out every rewire to BS 7671 standards, and issue an Electrical Installation Certificate on completion that notifies building control and provides the documentation you will need when you come to sell the property.

Installing a home EV charger makes charging your electric vehicle safer, faster and more convenient. At Chelmsford Electricians, we install professionally approved EV chargers designed to suit modern homes and vehicles.
We begin by assessing your existing electrical supply, consumer unit and parking setup. This ensures the charger is installed safely, complies with current regulations and performs reliably. We also install smart chargers, allowing you to schedule charging during off-peak hours and monitor usage via mobile apps.
Older properties often have wiring systems that are no longer suitable for modern electrical use. Rewiring improves safety, reliability and capacity, particularly when renovating or extending a home.
We carry out full and partial rewires, carefully planned to minimise disruption. This includes replacing outdated wiring, upgrading sockets and switches, and ensuring compliance with current standards.
A properly rewired home provides peace of mind and supports future electrical upgrades.
