Consumer Unit Replacement & Fuse Board Upgrades in London
Your consumer unit (fuse board) is the heart of your electrical system. Older boards may lack protections found in modern installations; an assessment establishes what improvements are needed. AC Kinetic supplies and fits modern RCBO consumer units across London — safer circuits, individual protection and full certification on completion.
Why upgrade your fuse board
An assessment of the existing installation determines the protective devices needed. Individual RCBOs combine overcurrent and residual-current protection and can reduce the number of circuits affected by a fault. We explain the suitable arrangement before quoting.
What's included
We agree a written scope for the replacement board, protective devices, connections, labelling, testing and Electrical Installation Certificate. The circuit count and assessment determine the equipment. Any remedial wiring work and required notification are identified in the quotation.
Signs you need a new consumer unit
Repeated tripping, heat damage, damaged enclosures or inspection findings warrant investigation. An older board may need improvement, but its age alone does not establish the required work. We assess the cause and explain whether repair, replacement or circuit work is appropriate.
Planning a consumer unit upgrade
Before we quote
Send a photo of the existing board and tell us about the property, circuit count and planned additions such as an EV charger. We check the installation and agree the protection and scope appropriate to the work.
During the work
The electricity supply must be isolated. Arrange access to the board and testing points, and discuss essential equipment with us beforehand. Existing wiring faults may need attention before circuits can be safely reconnected.
Clear exclusions
A replacement board does not automatically include rewiring the property or correcting every existing fault. We explain any extra work and agree the price before proceeding.
What you receive
The agreed installation, testing and appropriate electrical certification. We explain circuit identification and protective-device operation, and handle any building-regulations notification required for our work.

Consumer Unit / Fuse Board Upgrades — FAQs
Straight answers to the questions we're asked most.
How much does a consumer unit replacement cost?
Cost depends on the size of board required (number of ways/circuits) and site conditions. We quote fixed prices that include labour, materials and certification — contact us with your circuit count for an exact figure.
How long does it take to replace a fuse board?
The time depends on circuit count, access and testing findings. We agree the planned power interruption with you before booking. Existing faults may need repairs before affected circuits can be reconnected safely.
Do I legally need to upgrade my consumer unit?
The age or appearance of a consumer unit alone does not determine whether it must be replaced. We assess its condition, protective devices and any inspection findings, then explain the work needed for your installation.
Will I get a certificate?
We provide an Electrical Installation Certificate for the replacement and handle any building-regulations notification required for the work. The quotation explains the agreed scope and documentation.
