Losing power without warning is unsettling, and the urge to call for immediate help is a completely natural reaction. But, before reaching for the phone, it is worth taking a moment to think about what is actually happening. A power cut and an electrical fault are two distinct issues that require very different responses, and knowing which one you are dealing with allows you to act correctly, keep everyone in the property safe, and avoid calling out an engineer unnecessarily.

What Is a Power Cut?

A power cut is a loss of supply from the national grid. It originates outside your property and affects everyone connected to the same network in your area. When a power cut occurs, the problem lies with your electricity distributor’s infrastructure rather than anything inside your home or business.

The following signs suggest you may be experiencing a power cut rather than an internal fault:

  • All power has gone simultaneously: sockets, lights, and appliances have all stopped working at once
  • Neighbours in your street or building have also lost power
  • Your consumer unit shows no tripped switches or blown fuses
  • There is no smell of burning, no visible damage to any fittings, and no flickering before the outage occurred

If your neighbours are also affected, visit the UK Power Networks website or call 105, the free service that connects you with your local electricity network operator.

What Is an Electrical Fault?

An electrical fault originates inside your property’s wiring, consumer unit, or connected appliances. Unlike a power cut, an internal fault typically affects only part of the property, such as a single circuit, a specific room, or a group of sockets, rather than everything at once.

Electrical fault finding is a common requirement for many residential and commercial customers across Ongar and the surrounding areas. In most cases, the fault can be traced and resolved efficiently within a single visit. Common causes include overloaded circuits, damaged wiring, malfunctioning appliances, and defective consumer units — all of which require a qualified engineer to diagnose and address safely.

Signs you may be dealing with an internal electrical fault include:

  • Only part of your property has lost power — one room, one circuit, or one set of sockets
  • A switch on your consumer unit has tripped to the off position
  • You noticed flickering lights, buzzing sounds, or a burning smell before the power went
  • The outage followed the use of a specific appliance

If a switch has tripped on your consumer unit, try resetting it once. If it trips again immediately, do not continue resetting it — this indicates an ongoing fault that needs to be investigated by a qualified electrical contractor serving Hertford and North London before it can be safely restored.

When Should You Call an Electrician?

Once you have established that the problem lies within your property rather than with the wider supply, calling a qualified electrician is the right next step. Attempting electrical repairs or modifying wiring without the appropriate skills can be dangerous and may not comply with Part P requirements for domestic electrical work.

Whether you’re dealing with a tripped consumer unit, complete loss of power to part of your property, or a fault that has developed gradually over time, our NICEIC-approved engineers can diagnose and resolve the issue safely, with many faults cleared on the first visit.

For non-emergency situations — such as intermittent faults, flickering lights, or concerns about ageing wiring — a scheduled electrical inspection from a local Hertfordshire electrician is the appropriate route, allowing a thorough assessment of your property’s electrical installation without the time pressure of an emergency.

Frequently Asked Questions

How do I know if I have a power cut or an electrical fault?

– Check whether your neighbours are also affected and look at your consumer unit. If only part of your property has lost power and a switch has tripped, the problem is most likely an internal fault.

Should I reset a tripped switch on my consumer unit?

– You can try resetting it once. If it trips again immediately, do not continue — call a qualified electrician to safely investigate the underlying fault.

Can I investigate an electrical fault myself?

– No. Electrical fault finding should only be carried out by a qualified, NICEIC-approved electrician. DIY electrical work can be dangerous and may breach Part P of the Building Regulations.

How quickly can Sheaworks respond to an emergency electrical fault?

– Sheaworks Ltd provides a rapid emergency response, with arrival times depending on location, availability and demand.

What should I do while waiting for an electrician to arrive?

– Switch off and unplug any appliances connected to the affected circuit, avoid repeatedly using the tripped consumer unit switch, and keep away from any area where you notice burning or sparks.
