Step-By-Step Consumer Unit Installation Process
1. Site Survey and Fixed Quote
The process begins with a detailed site survey.
We evaluate your current fuse box and wiring system to determine the most suitable consumer unit for your property based on the electrical load.
Once the inspection is complete, we provide a clear and accurate fixed-price quote — with no hidden or extra costs.
2. Power Isolation and Safety Precautions
Before starting any work, our team isolates the power supply to prevent electrical hazards.
We use professional lock-off and verification procedures to ensure your system is completely de-energized.
Protective coverings are placed to keep your home or workplace clean and safe throughout the process.
3. Removing the Old Fuse Box and Safe Disposal
We carefully remove your existing fuse box or consumer unit that needs replacing.
All disconnections are carried out in an orderly and controlled manner to maintain cable integrity for the new installation.
The old unit is then disposed of responsibly in compliance with WEEE environmental standards.
4. Installation of the New Fire-Rated Metal Consumer Unit
Next, we install a modern, 18th Edition fire-rated metal consumer unit, complete with RCDs, MCBs, and RCBOs suited to each circuit.
All work is carried out by NICEIC-approved electricians who ensure that every connection is secure, neat, and properly labelled.
We use only branded, high-quality consumer units that comply with BS EN 61439-3 safety standards.
5. Circuit Testing and Labelling (BS 7671 Compliant)
Once installed, each circuit is thoroughly tested for continuity, insulation resistance, polarity, and RCD operation.
We confirm that the system fully complies with BS 7671 (IET Wiring Regulations), ensuring safe and reliable performance under load.
Every circuit is clearly labelled, making it easy to identify its function later on.
6. EIC Certification and Building Control Notification
After successful testing, we issue an Electrical Installation Certificate (EIC) — confirming that your new consumer unit meets all UK wiring regulations.
If required, we also handle Building Control notifications under Part P of the Building Regulations, saving you time and hassle.
7. Follow-Up and Demonstration
Once the work is complete, we provide a full handover.
Your electrician will explain the layout of the new consumer unit, demonstrate how to reset circuit breakers, and share maintenance tips for ongoing safety.
We also offer aftercare services should you require any additional guidance or future electrical support.
Typical Installation Time
Most consumer unit installations take between 4–8 hours, depending on the size of your property and any necessary remedial work.
Our team works efficiently and safely to minimise disruption and restore power as quickly as possible.
