Consumer Unit Replacement in Congleton
Consumer-unit replacement with pre-change circuit checks, labelling, testing and an Electrical Installation Certificate.
Before choosing a new unit
A replacement planned around the existing installation.
The consumer unit contains the protective devices for the installation. Inspection and testing identify defects before existing circuits are connected to the new equipment. The replacement is then installed, labelled and tested before handover.
Reasons for an upgrade
Protection selected for the supply and existing circuits.
Pre-change checks establish the condition of the circuits before the replacement equipment is specified.
Improved RCD or RCBO protection
Clearer circuit identification and labelling
Upgrades before further electrical work

Frequently asked questions
Questions about replacing a fuse box or consumer unit.
How do I know if my fuse box needs replacing?
Replacement should be based on condition, available protection, test results and planned alterations—not age alone. An assessment can establish whether replacement is justified and why.
Will the power be off all day?
The supply must be isolated during replacement and testing. The duration depends on the installation and any circuit defects found, so plan for a substantial period without power.
What documents will I receive?
A consumer unit replacement is issued with an Electrical Installation Certificate. Because it is notifiable work in England, the quotation also confirms the Building Regulations route and the separate completion or compliance document you will receive.
