Your fuse board, also known as a consumer unit, is one of the most important safety features in your property. It controls and distributes electricity throughout your home while helping to protect you, your family, and your appliances from electrical faults.
However, like any electrical component, fuse boards can become outdated over time. If your consumer unit is showing signs of age, it may no longer provide the level of protection expected from a modern electrical system. Circuit Electrical provides fuseboard services alongside domestic and commercial electrical work throughout Wiltshire.
1. Your Circuits Frequently Trip
An occasional trip isn’t always a cause for concern. However, if your circuits are regularly tripping without an obvious reason, it could indicate that your fuse board is struggling to cope with the demands of your property.
A qualified electrician can determine whether the fault lies with the consumer unit itself or elsewhere within the electrical installation.
2. You Still Have an Old Fuse Box
Older fuse boxes with traditional wire fuses lack many of the safety features found in modern consumer units.
Modern fuse boards are designed to offer enhanced protection, helping to quickly isolate faults and reduce the risk of electrical hazards. If your fuse board hasn’t been updated for many years, it may be worth considering an upgrade.
3. Burning Smells or Signs of Heat
A burning smell, discolouration around the fuse board, or signs of overheating should never be ignored.
These warning signs could indicate a serious electrical issue that requires immediate attention from a qualified electrician. If you notice anything unusual, it’s important to have the system inspected as soon as possible.
4. You’ve Added New Electrical Demands
Modern homes use more electricity than ever before.
Home offices, electric showers, underfloor heating, EV chargers, and kitchen appliances can all place additional demands on your electrical system. Circuit Electrical provides services including EV charging installations and underfloor heating, both of which can increase power requirements within a property.
If your fuse board is older, it may not be designed to support these increased electrical loads efficiently.
5. Flickering Lights
If your lights regularly flicker or dim, there may be an underlying electrical issue that requires investigation.
While faulty bulbs can sometimes be the cause, recurring problems throughout the property may indicate faults within the electrical system, including issues connected to the consumer unit.
6. You’re Planning Renovations
Home extensions, loft conversions, and major renovations often require additional circuits and electrical work.
Before starting a project, it’s worth having your existing fuse board assessed to ensure it can safely accommodate any new electrical installations.
7. Your Property Hasn’t Had an Electrical Inspection in Years
Regular electrical inspections help identify potential issues before they become serious problems.
Circuit Electrical offers electrical testing services for domestic and commercial properties, helping customers ensure their systems remain safe and compliant.
If your electrical installation hasn’t been professionally inspected for a long time, now may be the perfect opportunity to assess the condition of your fuse board.
