Signs You Might Need an Upgrade
- Your fuse box has a wooden back, rewirable fuses, or a black plastic switch rather than modern circuit breakers
- You don’t have RCD (residual current device) protection on your circuits
- Your EICR has flagged the consumer unit as a fault or improvement recommendation
- Breakers trip repeatedly, or you notice warm plug sockets, switches, or a burning smell
- You’re planning an extension, EV charger, solar installation, or other major electrical addition and need extra capacity
- Your consumer unit is more than 10–15 years old
If any of this sounds familiar, it’s worth getting it checked — a consumer unit upgrade is one of the most common recommendations to come out of an EICR.
Why Upgrade Your Consumer Unit
Safer circuits, a compliant installation, and headroom for whatever you add next.
Improved Safety
Modern consumer units include RCD and RCBO protection, which cuts power far faster than old fuses in the event of a fault — significantly reducing the risk of electric shock and electrical fire.
Insurance & Compliance
An outdated consumer unit can be flagged on an EICR and, in some cases, may affect landlord compliance or insurance validity. An upgrade brings your installation up to current wiring regulations (BS 7671).
Ready for What’s Next
A modern consumer unit with spare ways makes it easier to add an EV charger, solar & battery system, or home extension down the line without a second unit or major rework.
Our Process
Four steps from assessment to certificate — usually inside a single day.
Free Assessment
We take a look at your existing consumer unit and wiring, either as a standalone visit or as part of an EICR.

In most homes, a consumer unit upgrade is completed within a day, with minimal disruption.
Certification
You receive an Electrical Installation Certificate confirming the work meets current regulations.
Pricing
A straightforward domestic upgrade starts at £450. Larger properties, or units with more circuits, typically run £550–£950 — we confirm the exact figure at assessment.
Frequently Asked Questions
How do I know if my consumer unit needs replacing?
Common signs include a wooden-backed fuse box, rewirable fuses, no RCD protection, an EICR recommendation, or frequent tripping. We’re happy to take a look and give you an honest assessment.
How long does a consumer unit upgrade take?
Most domestic upgrades are completed in a single day.
Will I be without power during the upgrade?
Yes, briefly — we’ll need to isolate the supply while we swap the unit over, typically for a few hours during the job.
Do I need a consumer unit upgrade before getting an EV charger or solar panels?
Not always, but if your existing unit is old or has no spare capacity, we may recommend one as part of the installation. We’ll confirm this during your survey.
Will I get a certificate for the work?
Yes — you’ll receive an Electrical Installation Certificate confirming the work meets current wiring regulations (BS 7671).
