Conducting a regular electrical safety check is crucial for preventing hazards such as fires and shocks in domestic and commercial properties. However, many properties in the UK are hiding outdated or overloaded electrical systems that no longer meet modern demands.
Here at Evolution Electrical, we recommend regular inspections and maintenance to keep your system in top condition. In this article, we outline the five key signs that indicate it’s time to upgrade your electrical system.
Frequent circuit breaker trips or fuse blows
Circuit breakers and fuses are designed to protect your electrical system by cutting off power when there’s an overload or fault. However, if you suffer from frequent circuit breaker trips or blown fuses, it’s usually a clear sign that your system struggles to handle the electrical load.
- Domestic: the increase in electrical appliances — from smart TVs to electric car chargers — puts older wiring systems under pressure.
- Commercial: if you use more electrical equipment, the system might need upgrading to prevent constant disruptions to your workflow.
Flickering or dimming lights
If your lights flicker or dim when you turn on an appliance, it may be a sign that your electrical system has become overloaded. This often happens when large appliances like refrigerators, washing machines or heating systems draw more power than the wiring can handle.
- Domestic: older homes are prone to faulty lights if the wiring hasn’t been updated in decades. Modern technology may mean your wiring is no longer fit for purpose.
- Commercial: offices, factories or retail spaces with flickering lights can be caused by outdated or improperly distributed wiring, especially if your business has expanded.
Burning smells or scorched sockets
One of the most concerning signs that you need to upgrade your electrical system is the smell of burning or the sight of scorch marks around sockets and switches. This could indicate a serious issue with the wiring or electrical components overheating.
A burning smell is a sign of an electrical short, faulty wiring or overloaded circuits, which poses a serious fire risk. If you detect any unusual smells or see scorch marks, switch off the power at the fuse box and book an electrical safety check with a qualified electrician immediately.
Outdated wiring and electrical panels
If your property is more than 25 years old and hasn’t had a recent electrical upgrade, your wiring could be old and not fit for purpose. Electrical systems with old fuse boxes, instead of modern circuit breakers, are not designed to handle today’s power demands.
- Domestic: homes built in the 1970s or before could be hiding dangerous wiring, which can overheat and cause fires. It could be time for an electrical safety check.
- Commercial: older offices and factory buildings might have original wiring and electrical panels that can’t support modern technology. An upgrade is essential to avoid safety risks and ensure you’re compliant with health and safety regulations.
Limited or inadequate power outlets
Not having enough power sockets is a common issue in older properties, where electrical systems were not designed to accommodate the number of devices we use today. Relying heavily on extension cords and adapters to plug in multiple appliances can overload circuits and create safety hazards.
- Domestic: if you use extension leads to charge phones, or plug in kitchen appliances, this is a clear sign your home’s electrical system needs upgrading.
- Commercial: workplaces with multiple computers, printers, and other devices can suffer from overloaded sockets. This strains the electrical system and poses a fire risk. Installing additional outlets will ensure a safer work environment.
