Simply Electrical Contractors

Modern circuit protection, properly assessed

The consumer unit distributes electricity around the property and contains protective devices for the individual circuits. Replacement may be considered when equipment is damaged, obsolete, unsuitable for planned work or lacks the protection required for the installation.

A consumer unit should not be selected in isolation. Existing circuits, earthing and bonding arrangements, available space and the condition of the installation all need to be assessed before an upgrade is specified.

Simply Electrical Contractors undertakes consumer unit work across London. The completed installation is tested and the relevant certification for the work is provided and explained.

Common questions

Useful information before you enquire

For advice about a specific property, contact the team with the postcode and job details.

Does every old fuse box need replacing?

Not automatically. Condition, suitability and the protection provided should be assessed before deciding whether replacement is appropriate.

Will the power be off during installation?

Yes. A consumer unit change requires an agreed period without power. The likely duration and access requirements are discussed before the work.

Are the circuits tested?

Yes. Testing is an essential part of consumer unit work and may identify existing defects that need attention.

Will I receive certification?

The appropriate electrical certification for the completed installation work is provided after satisfactory testing.
