Old fuseboxes often come to attention during kitchen refits, extensions or repeated nuisance faults. The consumer unit is visible, but the hidden circuits decide whether the work is straightforward.
A good electrician will check the condition of the installation, not only the number of ways in the new unit. That is why two houses with similar boards can get very different quotes.
Consumer-unit upgrade quote factors
| Factor | What gets checked | Why it affects the job |
|---|---|---|
| Existing circuits | Condition, labels and test results | Faulty circuits may need repair before reconnection. |
| RCD or RCBO layout | Protection strategy for circuits | Modern protection improves safety but needs proper design. |
| Earthing and bonding | Main earth, gas and water bonding | Missing or undersized bonding can stop a simple swap. |
| Space and access | Meter cupboard or board location | Tight locations add time and may need layout changes. |
| Certification | Testing and paperwork | The job is not finished without proper test records. |
Consumer-unit upgrade readiness checker
Use this to decide whether to ask for an EICR or upgrade quote. It does not diagnose the installation.
Start with testing
A board swap can expose faults on old circuits.
Protection choices
RCD and RCBO layouts should match the property, not a generic package.
Bonding can block progress
Earthing and bonding issues often appear before replacement.
Paperwork matters
Testing and certification are part of the deliverable.

FAQ
Should I get an EICR before a consumer-unit upgrade?
Often yes. An EICR can show whether existing circuits are safe enough to reconnect to a new board.
Why does a consumer-unit quote vary so much?
Existing circuit condition, bonding, access, number of circuits and protection layout can all change the job.
Can ABC Home replace my consumer unit?
ABC Home can coordinate renovation and electrical work routes, but consumer-unit replacement itself should be handled by a qualified electrician with proper testing and certification.
Planning work in Aberdeen? ABC Home can coordinate the practical kitchen, renovation and electrical route through electrical services and kitchen fitting where the project overlaps.
