Why Regular Electrical Inspections Matter: What Could Be Hiding Behind Your Walls?
When everything appears to be working normally, it can be easy to assume that your electrical installation is safe.
Lights come on, sockets work and appliances power up — so everything must be fine, right?
Unfortunately, not always.
Electrical faults aren’t always obvious. Some problems can remain hidden for years, only becoming apparent when an electrician carries out a thorough inspection and testing, or when renovation work exposes something that shouldn’t be there.
At Pentacle Electrical and Security Ltd, we regularly come across electrical installations where closer inspection reveals issues that aren’t visible during everyday use.
What can an electrical inspection uncover?
An electrical inspection is about much more than checking whether the lights and sockets work.
An electrician will look at the condition of the installation and, where appropriate, carry out testing to assess whether circuits and protective devices are operating correctly.
Depending on the installation, this can identify issues such as:
• Loose or poorly made connections
• Signs of overheating or burning
• Damaged cables and accessories
• Incorrect or unsuitable alterations
• Poorly terminated conductors
• Inadequate earthing or bonding
• Deterioration caused by age, damage or environmental conditions
• Previous electrical work that may not have been carried out correctly
Some of these problems can present a genuine risk of electric shock or fire if left unidentified.
What could be hiding behind a wall?
Renovation work can sometimes reveal a surprising amount about the history of an electrical installation.
For example, while working during a kitchen renovation, we uncovered cable joints that had been buried within the wall.
This is exactly the sort of thing that may remain completely hidden from view once a property has been finished.
Out of sight doesn’t necessarily mean out of mind when it comes to electrical safety.
Electrical alterations should be planned and carried out so that connections are made using appropriate methods and, where required, remain accessible for inspection and maintenance.
That’s why renovation work is also a good opportunity to have existing electrical installations checked before walls, ceilings and cupboards are closed again.
Small problems can become big problems
Another issue we commonly see is evidence of overheating around electrical connections.
A loose connection can create increased resistance at the point of contact. Under load, this can result in heat being generated at the connection.
Over time, excessive heat can damage terminals, accessories and cables.
In more serious circumstances, overheating can contribute to an electrical fire.
A connection might still appear to work perfectly, but that doesn’t necessarily mean it is safe.
This is one of the reasons inspection and testing are so important.
What is an EICR?
An Electrical Installation Condition Report (EICR) is a formal assessment of the condition of an electrical installation.
During an EICR, the installation is inspected and appropriate electrical tests are carried out. The findings are recorded and any defects that require attention are identified.
An EICR can be particularly useful for:
• Homeowners who want reassurance about the condition of an older installation
• Landlords who need to meet their legal obligations
• Businesses and commercial premises
• Property owners following a change of use or significant alterations
• Anyone purchasing a property who wants to understand the condition of the electrical installation
The frequency and requirements for inspection depend on the type of property, its use, the condition of the installation and other relevant factors.
For landlords in England, there are also specific legal requirements relating to electrical safety in privately rented properties.
Don’t wait for something to go wrong
One of the biggest misconceptions about electrical safety is that a fault will always make itself known.
Unfortunately, electrical problems don’t always give you an obvious warning.
If you notice:
• Burning smells
• Discolouration around sockets or switches
• Buzzing or crackling sounds
• Warm or hot accessories
• Flickering lights
• Frequently tripping protective devices
• Damaged cables or accessories
it’s worth getting the installation checked by a suitably qualified electrician.
Even where none of these warning signs are present, an older installation may still benefit from an inspection.
Electrical safety during renovations
If you’re renovating a kitchen, bathroom, extension or another part of your property, don’t just think about the new electrical work.
It’s worth considering what is already there.
Renovations often provide an opportunity to access areas that have been hidden for years. Existing cables, joints, accessories and alterations can then be inspected before everything is covered up again.
Finding an issue at this stage is far better than discovering it after the walls have been finished.
Safety isn’t just about what’s visible
A professional electrical installation should provide reliable service while also incorporating appropriate measures to protect people and property.
That’s why inspection and testing are such an important part of electrical work.
Sometimes the most important things an electrician finds are the things you can’t see.
The buried cable joints we discovered during a recent renovation are a perfect example — something that was completely hidden until the surrounding work gave us the opportunity to investigate.
You don’t have to wait for an electrical fault to occur before checking the condition of your installation.
If you’re unsure when your electrical installation was last inspected, you’re renovating a property, or you’d simply like to know more about the condition of your electrics, an inspection could provide valuable peace of mind.
