Consumer unit replacement
What a consumer unit does
The consumer unit distributes electricity around a property and contains protective devices for its circuits. An upgrade replaces the existing board and allows the installation to be assessed, identified and tested as part of the work.
Who may need an upgrade
A replacement may be considered by homeowners planning improvements, landlords addressing inspection findings, or businesses updating an older installation. The right approach depends on the existing board, circuit condition and intended electrical work.
Common reasons for replacement
- An older or damaged enclosure
- Limited protection on existing circuits
- Poor or missing circuit labelling
- Changes to the property that require electrical alterations
Benefits of an organised upgrade
Modern protective devices can improve how individual circuit faults are managed. Clear labelling also makes the installation easier to understand, while testing helps identify issues that may need attention before or during replacement.
Consumer unit FAQs
Does every old consumer unit need replacing?
No. Age alone does not determine whether replacement is required. The unit and wider installation should be assessed before recommendations are made.
Will the power be turned off?
Yes, power needs to be isolated while the consumer unit is replaced and tested. The likely disruption can be discussed before work starts.
Is testing included with replacement?
The relevant circuits need to be tested as part of the replacement process, with any concerns explained clearly.
