Built around your property

Homeowners

Consumer unit upgrades planned around your existing wiring, circuit requirements and available space.

Landlords

Replacement where an electrical assessment identifies defects or unsuitable protection.

Property professionals

Review board suitability for extensions, kitchen upgrades and changing electrical demand.

Managing & letting agents

Plan tenant access, temporary power isolation and records around property schedules.

What your replacement includes

A consumer unit replacement involves assessment, safe circuit transfer and testing, as well as fitting the new board.

Existing installation

Review the board, visible wiring, circuit count, access and known electrical concerns before defining the scope.

Earthing & bonding

Check that earthing, main protective bonding and relevant supply equipment are suitable for the altered installation.

Board & circuit protection

Select suitable capacity and protective devices for the installation, considering surge protection where applicable.

Safe circuit transfer

Isolate the supply, remove the old board and reconnect circuits securely. Unsafe circuits need appropriate action before reconnection.

Inspection & testing

Inspect and test the completed work, check protective-device operation and clearly identify each circuit.

Tested work.
Clear records.

Your Electrical Installation Certificate records the replacement work and its test results. Keep it with your property documents.

Confirm the applicable Building Regulations compliance route and documentation with your installer. These records serve a different purpose from the electrical certificate.

At handover

Suitable protection. Clear circuit control.

From assessment to handover

01

Assessment & quotation

Review the board, circuit count, access and known concerns. Agree the equipment and scope.

02

Isolation & replacement

Isolate power, remove the old board and fit the new consumer unit with organised circuit connections.

03

Inspection & testing

Verify the completed work and connected circuits, including protective-device operation.

04

Certification & handover

Label the board, provide the appropriate records and explain the new protective devices.

When should you consider an upgrade?

Age alone does not decide whether a fuse box needs replacing. Review its condition, protection and suitability when concerns arise.

Different properties.
Practical planning.

Occupied & rented homes

Arrange access and discuss the expected loss of power before work begins. Timing depends on circuit count, testing and existing wiring.

Alterations & added demand

An extension, kitchen upgrade, EV charger or heat pump can change electrical requirements. Assess whether the existing board remains suitable.

Why choose FRA Expert?

FRA Expert follows a structured approach: assess the installation, select suitable equipment, complete the work, test the result and provide clear documentation.

If testing identifies wiring defects, additional remedial work may be needed. The findings and required action should be explained so you understand the next steps.

Prepare for your installation

Share any recent EICR, electrical certificate and details of known faults. Confirm access to the consumer unit and agree the expected downtime.

Ask what the quotation includes and how unexpected defects will be handled. Keep the completed installation records for future electrical work.

Frequently Asked
Questions

No. Age alone does not make a board unsafe. Its condition, protection, suitability for alterations and any defects found during assessment determine whether replacement is needed.

Many straightforward domestic replacements can be completed within a working day. Circuit count, access, testing and wiring condition can affect timing. Discuss expected power downtime before the appointment.

An Electrical Installation Certificate should record the replacement work and test results. Confirm the applicable Building Regulations compliance documentation with your installer and retain both with your property records.

A separate full EICR is not automatically required before every replacement. The electrician must assess the installation and complete the necessary inspection and testing. Wider concerns may justify an EICR.

An RCBO combines overcurrent and residual-current protection for an individual circuit. This can limit the effect of one fault on unrelated circuits. The suitable arrangement depends on the installation.

Additional remedial work may be needed. The findings and proposed action should be explained, and unsafe circuits must not simply be reconnected without appropriate action.
