YOUR CONSUMER UNITS ENQUIRY
Plan your consumer units work
Discuss consumer-unit replacement or remedial work with inspection findings and the present installation described. A new enclosure should be specified alongside required circuit checks.
What to include in your enquiry
- Why you are considering work on the consumer unit
- Any existing inspection report or known faults
- Access to the unit and the property’s occupancy arrangements
- State whether you own, rent or manage the property and who can authorise this consumer units work
What should the quote cover?
Specify pre-work assessment, the proposed equipment, treatment of discovered defects, testing and completion documents. Ask what extra work is provisional and how the household will know what has actually been completed.
Will replacing the consumer unit fix every circuit problem?
No. The board is one part of the installation. Existing-circuit faults and required remedial work need assessment and their own defined scope.
Property and responsibility checks
Bring previous inspection findings and circuit information to the discussion. The enclosure’s age or a historic-building description alone does not prove every circuit must be replaced.
- Identify the actual property, asset and owner before commissioning changes
- Include relevant plans, reports or permission information; do not assume approval
- Agree access, protection and making good where the work affects retained surfaces

Is replacement actually needed?
Quick answer
Discuss consumer-unit replacement or remedial work with inspection findings and the present installation described. A new enclosure should be specified alongside required circuit checks.
Discuss a consumer-unit repair or replacement, including assessment of the existing installation and the testing needed for the proposed work.
The age or appearance of a consumer unit does not alone establish the condition of the installation. Explain the reason for considering replacement: damage, an inspection recommendation, additional circuits or a wider refurbishment. An electrician should assess the existing arrangement and propose a suitable solution. Changing the unit is not the same as rewiring every circuit, and a new enclosure does not repair all defects elsewhere. Ask which findings support the recommendation before comparing products or assuming the most expensive board is the right answer.
Protection and a suitable specification
The proposed protective devices and circuit arrangement should suit the actual installation and intended use. Ask the electrician to explain the design in plain language, including how faults and future maintenance will be handled. Device names on an advert are not a substitute for an assessment. Do not open the unit, select replacement breakers yourself or ask for protection to be bypassed to stop a trip. New loads, outbuildings and specialist equipment may alter the scope, so include them in the discussion before a quote is finalised.
Existing circuits need checking
Ask how the electrician assesses the existing circuits before replacement and deals with defects revealed by testing. A consumer-unit price should distinguish the unit change from remedial work elsewhere. Some findings may require correction before a circuit can safely be reconnected. Agree the approval process and what happens if an unexpected issue prevents completion. An EICR can inform planning where appropriate, but the business should explain the investigation needed for this job. Do not assume all circuits are covered by a promise simply to fit a new board.

Certification and alteration checks
A consumer-unit proposal should include assessment of the existing installation, the specified protective devices, testing and the documentation supplied at completion. Ask the electrician which notification route applies to the actual work; a replacement board is not evidence that every existing circuit is suitable without checks.
Preparing for the power interruption
Agree when power will be unavailable and how essential equipment, refrigeration, access systems or business operations are managed. Tell the electrician about medical or other critical equipment before choosing a date; safe arrangements need direct planning, not an assumption that the outage will be brief. Clear access to the unit without touching electrical parts. The proposed position, working space and any changes to surrounding cupboards should be agreed. In a rented or shared property, ensure the person authorising the work has also coordinated occupant access.
Consider access for future maintenance as well as the installation day. A unit placed behind stored items or within an unsuitable enclosure can be awkward to use and inspect. Ask the electrician to confirm a suitable proposed position and any related building work. Moving it is a separate scope from changing the equipment in its present location.

Handover and later changes
Ask for a readable circuit schedule and an explanation of normal user controls, without treating that handover as training to work inside the unit. Keep the relevant certificates and any unresolved recommendations. If a circuit was left disconnected, record why and what is required before reuse. Future additions should be assessed against the installation rather than simply placed on a spare way. For an enquiry, include the reason for replacement, postcode, existing report if available and planned changes, avoiding unnecessary private documents through the general form.
