What Does Consumer unit Upgrade Involve?

An old fuse board with rewireable fuses or an outdated MCB board does not give you the same protection as a modern consumer unit. Many homes in Cornwall, particularly older properties, still have boards fitted decades ago that no longer meet current safety standards. A new board with RCD and RCBO protection will trip much faster in a fault situation, significantly reducing the risk of electric shock or fire, and giving you far better peace of mind day to day. Beyond safety, an upgraded consumer unit can also make everyday life easier. Modern boards are clearly labelled, easier to reset if something does trip, and can accommodate additional circuits if you are planning future work such as an extension, an EV charger, or extra outdoor sockets. Many homeowners choose to upgrade their consumer unit at the same time as other electrical work, or ahead of selling a property, since it is one of the first things a buyer's surveyor will check. Ryan will assess your current board, explain exactly what condition it is in and why an upgrade may or may not be needed, and recommend the right replacement for your home rather than a one-size-fits-all solution. The upgrade itself is usually carried out in a single day, with all work notified to building control and a completion certificate issued once everything has been tested.

Most consumer unit upgrades are completed in a single day, from removing the old board to fitting, testing and certifying the new one. The exact time can vary depending on the number of circuits in your home and whether any additional work is needed, such as upgrading the earthing or bonding to meet current standards. Ryan will confirm a more precise timeframe once he has seen your existing setup during the free survey.
Yes, consumer unit upgrades fall under notifiable electrical work in England and Wales. As a NAPIT registered contractor, Ryan is authorised to self-certify this type of work, meaning he handles the building control notification directly rather than you needing to arrange it separately. You will still receive the same official paperwork and certification as if the council had inspected the job themselves.
Yes, your power will need to be switched off for most of the day while the old board is removed and the new one is fitted and tested. Ryan will let you know in advance roughly how long to expect, so you can plan around things like working from home, freezers, or anything else that depends on a continuous power supply. He will restore power circuit by circuit as testing is completed, rather than leaving everything off until the very end.
An RCD (Residual Current Device) protects a group of circuits together, so if a fault occurs anywhere within that group, all of those circuits will trip at once. An RCBO (Residual Current Breaker with Overcurrent protection) protects each individual circuit on its own, meaning a fault in one room, such as a faulty appliance, will only trip that specific circuit rather than cutting power to half the house. RCBOs generally offer more convenience and better fault isolation, though they do cost more than a standard RCD setup. Ryan will talk you through which option makes the most sense for your home and budget.
Not necessarily. Frequent tripping is often caused by a specific fault, such as a damaged appliance, a deteriorating cable, or moisture getting into an outdoor socket or light fitting, rather than a problem with the consumer unit itself. Ryan will diagnose the actual cause of the tripping first, and will only recommend a new board if your current one is genuinely outdated, damaged, or unable to provide adequate protection. If a straightforward fault is found and fixed, that may resolve the issue without any need to replace the board at all.
In most cases, yes. Ryan carries out the full upgrade, including removing the old board, fitting the new consumer unit, testing every circuit and completing the paperwork, all in a single visit. Occasionally, if the survey uncovers additional issues, such as damaged wiring or inadequate earthing that need addressing first, he will let you know in advance so a second visit can be planned rather than causing delays on the day.
