Assess first
Circuit count, earthing, bonding and existing protection are reviewed before equipment is selected.
Consumer-unit replacement and distribution work planned around the condition of the existing installation, the required protective devices and the results that need to be achieved.
Changing a consumer unit, often called replacing or upgrading a fuse box, does not erase faults or unsuitable wiring downstream. Existing circuits, earthing, bonding, loads and test results need to be understood so the proposed equipment is appropriate and unexpected remedial work is discussed clearly.
Circuit count, earthing, bonding and existing protection are reviewed before equipment is selected.
RCD, RCBO, surge protection and isolation requirements are considered for the installation.
Circuits are verified and the appropriate certification is provided for completed work.
The exact scope depends on the installation, access, test results and the outcome you need. Useful photographs and existing documents make the first discussion more productive.
Yes, where replacement is appropriate. Fuse box is common customer language for older consumer-unit equipment, but the connected circuits, earthing, bonding and test results still need assessment.
No. Age alone does not define the complete condition. The reason for replacement and the installation should be assessed.
Testing is necessary because the new protective equipment will be connected to those circuits.
Previously unknown defects may require a separate decision. Known assumptions and likely constraints should be discussed before work starts.
Send the location, a short description and any useful details about the affected circuit, consumer unit, equipment or existing report.
Urgent and out-of-hours fault work may be available by arrangement. The form is not a guaranteed 24-hour emergency service.
