Is the wiring behind your walls as safe as it should be?
It’s not something most of us think about. We flip a switch, charge our phones, boil the kettle and just expect everything to work.
It is only when something goes wrong, like the lights flickering, a socket buzzing, or a strange burning smell, that we start to worry.
The thing is, electrical problems often build up slowly and quietly.
By the time they become noticeable, the damage is usually already done and the repair costs can be much higher than expected.
That is why we always encourage our clients across Northern Ireland to stay ahead of potential problems.
A routine inspection now could save you from major expenses and serious risks down the line.
How often should you get your electrics inspected?
This is one of the most common questions we get.
For most homeowners, a full electrical inspection is recommended every 10 years.
If you’re renting out property, it’s every 5 years or at the start of each new tenancy. Businesses should also stick to a 5-year inspection cycle at minimum.
That said, those are only general guidelines.
If you’ve recently moved into an older home, noticed flickering lights, tripping breakers, or you’re planning a renovation, it’s worth booking one sooner.
We always remind our clients, these checks aren’t just about ticking boxes.
They’re about safety, peace of mind, and preventing a much more expensive problem down the line.
What can go wrong with outdated wiring?
More than most people think. We have worked in properties where the wiring had not been touched since the 1960s.
Back then, the average household had far fewer devices.
There were no smart TVs, no induction hobs, no tumble dryers running at full tilt every weekend, and certainly no electric vehicle chargers pulling power around the clock.
The electrical demand today is completely different from what those old systems were designed to handle.
Outdated wiring struggles to keep up.
It can:
- Overheat under modern loads
When too many appliances are drawing power through an old circuit, the wires can become dangerously hot.
This creates a serious fire hazard, especially when insulation is no longer in good condition.
- Become brittle and crack over time
As wiring ages, the insulation materials can degrade.
This is particularly common with rubber or cloth-insulated wires, which were used before more durable plastic coatings became standard.
Cracked insulation increases the risk of short circuits and exposed live conductors.
- Increase the risk of fire
Electrical distribution and appliances are among the top causes of accidental fires in UK homes.
Faulty or outdated wiring plays a big role in that.
Even a small fault, left undetected, can lead to dangerous consequences.
- Lead to unpredictable failures
Older wiring systems can behave in inconsistent ways.
One minute everything seems fine, and the next, a circuit trips or a plug socket stops working.
This unpredictability is frustrating, but more importantly, it is unsafe.
For businesses and rental properties, there is even more at stake.
Out-of-date wiring can lead to failed inspections and compliance issues, which may affect your insurance cover or leave you liable in the event of an incident.
We have worked with landlords across Belfast and homeowners throughout Northern Ireland who were unaware of hidden issues until they had a proper EICR carried out.
In many of those cases, a timely inspection prevented serious problems and saved them from costly penalties.
Outdated wiring is not just a sign of an old home.
It is a sign that your electrical system might be quietly falling behind modern safety standards.
That is where we step in to help bring things up to date before anything goes wrong.
What does an electrical inspection include?
When we inspect Glow Electric, it is not just a quick glance around your property.
We take the time to carefully check the safety, condition, and compliance of your entire electrical system.
Our inspections are thorough and designed to spot any issues before they turn into costly repairs.
During a typical visit, we include the following checks:
- Visual checks on all wiring, sockets, switches, and light fittings
- Testing of the fuse board and RCDs (residual current devices)
- Checks for any loose or damaged connections
- Earth bonding to metal pipes and other services
- Polarity tests and insulation resistance
- Detailed reporting and grading of any issues
How can electrical inspections help reduce energy bills?
This is one benefit that surprises a lot of our clients.
Electrical problems like loose wiring, poor connections or overworked circuits can waste energy.
They create heat, inefficiencies, and wear down appliances faster.
During an inspection, we can also advise you on upgrades that make a real difference.
For example:
- Replacing halogen lights with LED
- Installing smart thermostats or energy monitors
- Checking the load on circuits used by your most energy-hungry appliances
- Upgrading old fuse boxes to modern units with better protection and efficiency
Why landlords and letting agents need to take inspections seriously
You do not always need to wait for the five or ten-year inspection mark to take action.
Sometimes, your home or business will give you clear signals that something is not right.
These signs should never be ignored, because they often point to underlying problems that could become serious very quickly.
Here are some of the most common red flags that mean it is time to give us a call:
- Circuit breakers keep tripping
If your fuse board is cutting the power frequently, it could be a sign of an overloaded circuit, faulty wiring, or a problem with an appliance.
While one trip might be nothing to worry about, repeated tripping definitely needs to be looked at.
- Buzzing or crackling sounds from outlets or switches
Electricity should be silent. Any sort of buzzing, humming, or crackling noise is a warning sign.
These sounds can be caused by loose wiring, faulty switches, or worn-out components, and they may be a fire risk.
- Lights that flicker or dim without reason
If your lights randomly flicker or seem to lose power when other appliances are in use, it might mean your wiring is struggling to cope with the load.
It can also point to poor connections or faults inside the circuits.
- Plug sockets that feel warm to the touch
Sockets should never feel hot. A warm or hot socket can mean that wires are overheating behind the faceplate.
This should be checked straight away, as overheating wires can lead to fire.
- Switches or outlets that are discoloured or loose
Discolouration around a switch or socket often comes from heat or sparking.
Loose fittings can also leave wires exposed or moving around inside the wall, which creates a serious risk if left unchecked.
- A strong or unusual burning smell
If you smell something like burning plastic, especially around sockets or the fuse board, it could be insulation melting due to overheating.
This is one of the most urgent signs of a potential electrical fire and needs immediate attention.
According to data from the UK Home Office, electrical distribution faults account for a significant number of accidental dwelling fires.
Acting early can make all the difference. If you notice any of these signs, it is better to be safe than sorry.
What happens after an inspection?
Once we finish the inspection, our job is not just to hand over a technical report and leave you to figure it out.
We take the time to sit down with you and go through everything in plain language, making sure you understand exactly what we checked, what we found, and what comes next.
Your report will include:
- A full breakdown of what we inspected
We list everything we checked across your electrical system.
This includes circuits, sockets, switches, the fuse board, and any visible wiring. Nothing is rushed or skipped over.
- Any faults we discovered, clearly graded by risk
Each issue is marked with a code so you can see what needs urgent attention and what might be monitored over time.
For example, a C1 fault means there is a serious and immediate risk, while a C2 means action should be taken to prevent danger.
This grading system follows national safety standards and helps you prioritise repairs practically.
- Suggestions for improvements or safety upgrades
If we notice something that is not dangerous but could be made safer or more efficient, we will let you know.
That could include replacing an old fuse board with a modern consumer unit, adding extra RCD protection, or updating sockets in wet areas like bathrooms or kitchens.
- A clear pass or fail for compliance
If the system meets the required safety standards, the report will show a satisfactory result.
If it does not, you will know exactly why and what needs to be done to fix it.
This is especially important for landlords and business owners who need to stay compliant with legal regulations.
