The mornings are getting darker. The heating is starting to come back on. Outdoor lights are being used more often, tumble dryers are working harder and before long portable heaters, Christmas lights and all the other electrical demands of winter will be added into the mix.
For most of the year, we barely think about the electrics in our homes.
We plug something in. It works. We move on.
But winter can be a useful time to pay a little more attention.
It isn’t that cold weather suddenly makes a healthy electrical installation unsafe. Rather, our homes tend to place different demands on their electrical systems during the colder, darker months. Existing weaknesses can become more noticeable when equipment is used more frequently or outdoor electrics are exposed to wetter conditions.
At MKW Electrical Contractors, we work in homes throughout Whitley Bay, Tynemouth, North Shields, Newcastle and the surrounding North East, and many of the electrical problems we’re called to investigate begin with relatively small warning signs.
So before winter properly arrives, here are 10 things worth checking around your home.
1. Does Your RCD Actually Work?
Your RCD (Residual Current Device) is an important part of your home’s electrical protection.
It monitors the electrical current and can disconnect the supply rapidly when certain faults occur, helping to reduce the risk of electric shock.
Many RCDs have a button marked T or Test.
Electrical Safety First advises homeowners to check that their consumer unit includes RCD protection.
If you press the test button, the RCD should operate and disconnect the circuits it protects.
If it doesn’t operate, or you aren’t sure whether your home has appropriate RCD protection, it’s worth having it checked by a qualified electrician.
What if my RCD keeps tripping?
That’s different.
An RCD repeatedly tripping shouldn’t simply be treated as an inconvenience.
It can indicate a problem with an appliance, circuit or part of the electrical installation. If you find yourself continually resetting it without knowing why it’s happening, an electrician can carry out electrical fault finding to identify the cause.
We’ll be covering this in much more detail in a dedicated guide shortly.

2. Check Your Sockets for Heat, Damage or Discolouration
Take a quick look at the sockets you use most frequently.
You’re looking for things such as:
- scorch or burn marks
- cracking or physical damage
- unusual discolouration
- buzzing or crackling
- plugs that don’t feel secure
- sockets or plugs becoming unusually hot
These are all things that should be investigated rather than ignored.
Electrical Safety First specifically advises having sockets checked if they show burn marks or become hot, while unexplained circuit-breaker tripping or buzzing/crackling can also indicate an electrical problem.
If something looks, smells or sounds wrong electrically, don’t wait for it to get worse.
3. Think About How Many Extension Leads You’re Using
Winter has a habit of creating more plugs.
Portable heaters.
Lamps.
Christmas decorations.
Chargers.
Home-office equipment.
TVs and games consoles.
Before long, that one double socket behind the sofa can have a considerable amount connected to it.
Extension leads are useful, but they shouldn’t become a permanent substitute for having enough correctly positioned socket outlets.
High-powered appliances such as heaters are particularly important to consider. Electrical Safety First warns against overloading sockets and extension leads, especially with high-powered appliances.
And one rule worth remembering:
Never plug one extension lead into another.
If your home permanently relies on extension leads because there simply aren’t enough sockets where you need them, adding properly installed socket outlets may be the better long-term solution.
4. Bringing the Electric Heater Back Out? Check It First.
That portable heater that’s been sitting in the garage, cupboard or loft since last winter deserves a quick inspection before you switch it back on.
Look at the cable and plug.
Check for damage.
Make sure the heater itself hasn’t been damaged while stored.
And think carefully about where you position it.
Portable heaters should be kept away from curtains, furniture, clothing and other combustible materials, and shouldn’t be used for drying clothes.
If using a heater causes a socket to become hot or your electrics to trip, stop using it until the cause has been established.
5. Check Your Outdoor Electrics Before the Wet Weather Sets In
Outside sockets and lighting spend their lives dealing with conditions that indoor accessories don’t.
Rain, moisture, temperature changes and general weather exposure can all take their toll over time.
Before winter, visually inspect accessible outdoor electrical equipment.
Look for cracked covers, damaged fittings, loose accessories, condensation or obvious signs of water ingress.
If an outside socket or light starts causing your RCD to trip, particularly during or after rain, there could be moisture ingress or another fault that needs investigating.
Don’t repeatedly reset the RCD and hope the problem disappears.
6. Check Your Smoke and Heat Alarms
This isn’t strictly about your wiring, but it absolutely belongs on a winter electrical safety checklist.
Test your alarms.
It takes seconds.
Electrical Safety First recommends having a working smoke alarm on each floor of your home and testing alarms regularly. It also notes that alarm sensors deteriorate over time and many need replacing at around ten years, depending on the manufacturer’s specified replacement date.
If you have mains-powered interconnected alarms, check that they operate correctly and that you’re aware of their replacement dates.
It’s one of the easiest safety checks you can make.
7. When Did Anyone Last Check Your Consumer Unit?
Your consumer unit, sometimes still called the fuse box, is at the heart of your home’s electrical installation.
You don’t need to remove covers or touch anything internally.
Simply have a look.
Is it clearly labelled?
Do you know which switch controls which part of your house?
Does it have RCD or RCBO protection?
Is there any visible damage?
Has anything been stored tightly around it?
Modern consumer units can also incorporate additional protection such as Type A RCBOs and Surge Protection Devices (SPDs).
What Is Surge Protection And Do I Need It?
An older consumer unit doesn’t automatically mean that your electrical installation is unsafe, but if yours hasn’t been looked at professionally for many years, it may be worth understanding exactly what protection your home currently has.
8. Pay Attention to Flickering Lights
One lamp flickering can simply be a failing bulb.
But persistent flickering across fittings, lights behaving strangely, buzzing switches or problems affecting several areas shouldn’t automatically be dismissed.
These symptoms can have several causes, which is why guessing at an electrical fault is rarely useful.
If changing the lamp doesn’t solve the problem, or the issue keeps returning, have it investigated.
The same applies to switches that feel hot, crackle when operated or no longer operate consistently.
9. Know the Signs That Mean “Call an Electrician”
There are some electrical symptoms that shouldn’t be added to the bottom of next month’s DIY list.
Pay attention to:
Burning smells.
Scorching around sockets or switches.
Buzzing or crackling.
Repeated RCD or circuit-breaker tripping.
Damaged accessories.
Exposed wiring.
Sockets becoming unusually hot.
Loss of power to part of the property without an obvious explanation.
These symptoms don’t automatically tell us what the fault is, but they do tell us that something deserves investigation.
A qualified electrician can test the installation rather than relying on guesswork.
10. Ask Yourself One Simple Question: When Were Your Electrics Last Properly Checked?
For many homeowners, the answer is:
“I’m not actually sure.”
That’s surprisingly common.
An Electrical Installation Condition Report (EICR) is essentially an electrical health check for the fixed wiring in your property.
Rather than simply looking at whether the lights and sockets work, an electrician carries out inspection and electrical testing to assess the condition of the installation and identify deterioration, defects or areas requiring improvement.
Electrical Safety First recommends periodic inspection and testing at least every 10 years for an owner-occupied home, while rented properties in England are subject to specific electrical safety requirements including inspections at least every five years.
At MKW, we’ve also taken the EICR a stage further.
Alongside the technical NICEIC report, we provide our clients with an Electrical Health Report designed to explain the findings in straightforward language.
Why Our EICRs Are Different: An Electrical Report You Can Actually Understand
Because being told you have a C2 on Circuit 4 isn’t particularly useful if nobody explains what that means, why it matters and what should happen next.
Don’t just inspect it. Explain it.
Does Winter Mean I Need an Electrical Inspection?
Not necessarily.
If your installation has been properly maintained, recently inspected and isn’t showing any signs of problems, there’s no reason to arrange electrical work simply because winter is approaching.
But there are situations where it makes sense to get things checked.
If your electrics regularly trip, sockets are getting hot, accessories are damaged, you’ve recently moved into an older property, you don’t know when the installation was last inspected or you’re concerned about the condition of your consumer unit, an inspection can provide a much clearer picture.
The important thing is not to wait for a small warning sign to become a bigger problem.

FAQ SECTION
I’d definitely add this at the bottom of WordPress because it captures several longer-tail searches naturally.
Why does my electricity keep tripping in winter?
There isn’t one universal cause. Increased appliance use, faulty equipment, moisture affecting outdoor electrics or an existing circuit fault can all be possibilities. Repeated tripping should be investigated rather than continually resetting the protective device.
Should I have my electrics checked before winter?
There isn’t a requirement for homeowners to arrange an electrical inspection specifically for winter. However, if you’re experiencing repeated tripping, damaged or hot sockets, flickering lights or other warning signs, or your installation hasn’t been inspected for many years, arranging an electrical safety inspection can be worthwhile.
How often should a house have an electrical inspection?
Electrical Safety First recommends periodic inspection at least every 10 years for an owner-occupied home. Different requirements apply to rented properties.
Is it safe to use an electric heater on an extension lead?
High-powered appliances place significant demand on sockets and extension leads. Avoid overloading extension leads and follow the heater manufacturer’s instructions. If you’re regularly relying on extensions to power heating equipment, it may be worth having suitable permanent socket outlets installed.
Why does my RCD trip when it rains?
Moisture entering outdoor electrical equipment is one possible cause, but there are several potential reasons for RCD operation. An electrician can carry out testing to establish the actual cause rather than guessing.
What are the warning signs of an electrical problem?
Burn marks, unusual heat, buzzing or crackling, repeated tripping, damaged accessories, exposed wiring and persistent unexplained flickering are all signs worth investigating.
