20 Years’ Qualified, Accredited Consumer Unit & Rewiring Expertise

Consumer unit work covers more than fitting a new box. Existing circuits, earthing and bonding arrangements, cable condition and protective devices must be assessed so the replacement is suitable for the installation. Rewiring involves renewing affected cables and connections, followed by testing and certification.

RJW Electrical’s domestic work is carried out by fully qualified, insured and DBS-checked engineers. Projects are planned around the property’s existing wiring, intended electrical load and the extent of upgrading required, whether that means a consumer unit replacement or a wider house rewire.

Work is completed in line with the latest 18th Edition wiring regulations, with inspection and testing forming part of the process. This provides a documented basis for confirming that the completed installation has been assessed against applicable electrical requirements.

The Consumer Unit Installation and Rewiring Process

The process for consumer unit installation or house rewiring begins with understanding the property, its existing electrical system and planned demands. It then moves through preparation, controlled site work, inspection, testing, certification and handover.

  1. 01

    Initial enquiry and property details

    The process starts with basic information about the property, the type of electrical work required and any known concerns, such as outdated equipment, damaged accessories or frequent circuit problems.

  2. 02

    Electrical assessment

    The existing installation is reviewed to establish the condition and arrangement of the consumer unit, circuits, cables, earthing and bonding. For a rewire, this helps identify which parts require replacement and how the work will affect the property.

  3. 03

    Scope and quotation

    The findings are used to define the proposed work, including whether the requirement is a consumer unit replacement, partial rewire or full house rewire. The quotation should make clear what is included, which areas are affected and any preparation required.

  4. 04

    Preparation before work starts

    The work is planned around the property layout, existing wiring and intended electrical demand. Access requirements, affected rooms, fittings and the sequence of tasks are considered before site work begins.

  5. 05

    Installation or rewiring on site

    The engineer carries out the agreed electrical work, installing the new consumer unit or renewing the specified cables and connections. Work is managed systematically so circuits and associated components are dealt with as set out in the agreed scope.

  6. 06

    Inspection and testing

    After installation, the completed work is inspected and tested. Checks confirm that the relevant circuits, protective devices, earthing and connections have been assessed in accordance with applicable electrical requirements and the latest 18th Edition wiring regulations.

  7. 07

    Certification and handover

    The project is completed with the appropriate electrical documentation for the work carried out. The homeowner or landlord can then review what has been installed, understand any relevant recommendations and retain the certification for their records.

Compliance Evidence

RJW Electrical’s regional track record is supported by NAPIT, TrustMark and Electrical Safety Register membership, with documentation for completed work.

How disruptive is a house rewire?

Disruption depends on the property’s construction and wiring layout. A partial rewire affects fewer areas; a full rewire may require access beneath floors, within walls, and above ceilings during installation.

How long does consumer unit installation take?

Consumer unit installation times vary with circuit numbers, access, property layout and whether upgrades or replacement work is required. The electrician should confirm the planned sequence after assessing the installation.
