Fuse Box Replacement
Consumer unit upgrades in Solihull
Your consumer unit, the fuse board, is the heart of your electrical safety. DGC Electrical replaces old and unsafe boards across Solihull with modern units offering individual RCBO and surge protection, fully tested, certified and left tidy.
When to upgrade
Signs your fuse board needs upgrading
Older consumer units were never designed for the demands of a modern home. If your board still relies on rewireable fuses, or has no RCD protection, it may not trip quickly enough to protect you from a fault or shock. Replacing it with an 18th Edition unit brings the installation up to current safety standards.
It's worth booking an assessment if you recognise any of these:
- Old rewireable fuses, or a plastic board with no RCD protection
- A board that is cracked, scorched or warm to the touch
- Nuisance tripping, or circuits that keep failing
- Adding an EV charger, extension or electric shower
- An EICR that recommended an upgrade
- Buying a home with an ageing installation
What a consumer unit upgrade includes
We remove the old board, fit a modern replacement and test every circuit before handing over the certification. Working to the 18th Edition wiring regulations, a typical upgrade includes:
- A new 18th Edition consumer unit
- Individual RCBO protection on each circuit
- Surge protection (SPD) where appropriate
- Full testing and an Electrical Installation Certificate
- Safe isolation and neat make-good around the board
- A clear explanation of anything else we spot
If testing reveals a wider issue with the installation, we'll explain what we've found and quote any further work before carrying it out.

Consumer unit FAQs
Common questions
How long does a consumer unit upgrade take?
Most domestic upgrades are completed within a day; larger or older installations may take longer, which we'll confirm when we quote.
Will my power be off during the work?
Yes, the supply needs to be off for part of the day while we swap the board and test each circuit; we plan the timing with you.
Do I need a new board for an EV charger or EICR?
Sometimes. Adding an EV charger or acting on an EICR can require a board with the right protection; we'll tell you honestly whether yours is suitable.
What does it cost?
It depends on the size of your installation and the board you need, so we give you a clear quote before any work starts.
