Electric11 replaced an existing consumer unit in Wicklewood, near Wymondham, with an 18th Edition RCBO consumer unit incorporating surge protection. The completed upgrade provides modern circuit protection, improved fault isolation and a safer distribution point for the property’s electrical installation.
The customer required the existing consumer unit to be replaced with a modern board designed around current electrical safety requirements. The agreed specification included individual RCBO protection and a surge protective device, commonly shortened to SPD.
For customers considering a similar upgrade, Electric11 provides consumer unit replacement in Wicklewood for homes, rental properties and businesses. The wider team of electricians in Wicklewood can also assist with electrical testing, repairs, rewiring and planned installations.
Electric11 removed the existing consumer unit and installed one 18th Edition RCBO consumer unit with an integrated surge protective device. The new board brings the property’s circuit protection together in a modern, clearly managed installation.
Each RCBO combines overcurrent and residual-current protection for its connected circuit. This arrangement is designed to isolate an affected circuit when a qualifying fault occurs, helping to avoid unnecessary loss of power to unrelated circuits. The SPD adds protection against transient overvoltages that could otherwise affect connected electrical equipment.
Property owners in the wider NR18 area can learn more about consumer unit replacement in Wymondham or arrange support from a qualified electrician in Wymondham.
Testing and certification are essential parts of a consumer unit replacement. Following the installation, the relevant electrical checks verify the protective measures, circuit connections and operation of the new equipment. An electrical certificate will be issued in accordance with BS 7671 requirements.
Customers who need a broader assessment of an existing electrical installation can also arrange an EICR certificate in Wicklewood. An EICR is a separate inspection that assesses the condition of the property’s fixed wiring and identifies any observations requiring attention.
The property now has a modern RCBO consumer unit with surge protection in place of the previous board. The upgrade provides improved circuit-level protection, supports easier fault isolation and gives the customer clear certification for the completed electrical work.
This project did not generate electricity or directly reduce energy use, so no annual financial, energy or carbon savings have been assigned. Its value lies in electrical safety, modern protective technology and compliance-focused workmanship.
If your fuse box is outdated, damaged, frequently trips or lacks modern circuit protection, Electric11 can assess the installation and recommend an appropriate upgrade. Contact Electric11 to request a consumer unit assessment and a clear, no-obligation quote.

Consumer unit replacements depend on careful assessment, safe isolation and thorough electrical testing. Electric11 follows a structured process designed to select suitable protection for the property, minimise avoidable disruption and leave the customer with the required certification.
Existing Installation Assessment
The team reviews the existing consumer unit, connected circuits, electrical supply, earthing and bonding before the replacement scope is finalised. Any visible defects, access restrictions or additional work that could affect the upgrade are identified at this stage. For the Wicklewood project, the confirmed specification was an 18th Edition RCBO consumer unit with surge protection.
Clear Quote and Installation Plan
Electric11 sets out the agreed equipment, replacement work, testing and certification within a clear quotation. The installation is then planned around the property and the temporary interruption to its electrical supply, giving the customer a clear understanding of the work before it begins.
Safe Removal and RCBO Installation
The electrical supply is safely isolated before the existing consumer unit is removed. Electric11 then installs the new board, connects the circuits to the appropriate RCBO protection and incorporates the surge protective device. On this project, the replacement brought modern circuit-level protection and surge protection together in one consumer unit.
Inspection, Testing and Certification
The completed work is inspected and electrically tested to verify the installation and protective measures. The job record confirms that an electrical certificate will be issued in accordance with BS 7671, providing formal documentation for the completed consumer unit replacement.
Electric11 installed an 18th Edition RCBO consumer unit with a surge protective device. The supplied job record does not confirm the board’s number of usable ways, so that specification should be checked before publication.
An RCBO consumer unit uses protective devices that combine residual-current and overcurrent protection for individual circuits. This arrangement can help isolate a fault to the affected circuit instead of unnecessarily interrupting several unrelated circuits.
The SPD is designed to limit transient overvoltages within the electrical installation. This provides an additional layer of protection for connected electrical and electronic equipment.
Yes. The job record states that an electrical certificate will be issued in accordance with BS 7671 requirements following the replacement work and relevant testing.
Not directly. A replacement consumer unit improves electrical protection and distribution but does not generate electricity or guarantee lower consumption. For this reason, the case study records zero estimated annual energy, carbon and financial savings.
Contact Electric11 to arrange an assessment. The team can review the existing board, connected circuits and property requirements before recommending a suitable replacement.
