Changing a Consumer Unit & Testing the Installation | SLE Electrical Hailsham
Expert Electricians in Hailsham – Safe & Certified Consumer Unit Upgrades
If you’re looking for trusted electricians in Hailsham to upgrade your consumer unit (fuse board), SLE Electrical is here to help. A modern 18th Edition consumer unit is essential for the safety and efficiency of your electrical system, ensuring compliance with current regulations. In this post, we’ll explain the process of changing a consumer unit and why testing the installation is a crucial step.
Why Upgrade Your Consumer Unit?
Older fuse boards with rewireable fuses can pose a safety risk, as they lack modern protection features. Upgrading to a new consumer unit with RCDs (Residual Current Devices) and MCBs (Miniature Circuit Breakers) enhances safety by reducing the risk of electric shocks and fire hazards.
Signs you need a consumer unit upgrade:
✅ Frequent tripping of circuits
✅ No RCD protection (older fuse boards)
✅ Burning smells or buzzing sounds
✅ Visible damage or outdated wiring
If your electrical system is outdated, contact SLE Electrical in Hailsham for a professional assessment.
The Process of Changing a Consumer Unit
1. Initial Inspection & Testing
• Before replacing the unit, we conduct an Electrical Installation Condition Report (EICR) to check for any existing faults.
2. Safe Power Isolation
• We turn off the power supply and safely remove the old fuse board.
3. Installing the New Consumer Unit
• The new unit is fitted and wired to 18th Edition BS 7671 standards, ensuring full compliance.
4. Full Electrical Testing & Certification
• After installation, we conduct rigorous testing of all circuits, ensuring correct operation and safety.
• A certificate is issued to confirm compliance with regulations.
Why Testing Is Essential
After replacing a consumer unit, testing is crucial to:
✔ Ensure all circuits function correctly
✔ Identify and rectify any faults
✔ Confirm compliance with BS 7671 wiring regulations
✔ Provide peace of mind that your home or business is safe
At SLE Electrical, Hailsham, we take safety seriously and never complete an installation without a full test.
