Socket Not Working What to Check First in Alton

Published September 2026 | Socket not working what to check first

A homeowner in Alton came home one evening to find the extension lead powering their home office had gone completely dead - monitor, desk lamp, laptop charger, all of it stopped working at the same time. The lights in the same room were still on, so a full power cut was ruled out immediately. They tried the same socket with a different appliance, swapped the extension lead, and checked everything they could think of - but nothing made a difference. Twenty minutes later they called our team, convinced they were facing something serious.

They weren't. But the fault wasn't something they could have safely traced or fixed on their own.

What Was Actually Going On

Dead sockets have a short list of likely causes, and working through them in the right order is what separates a quick fix from an expensive misdiagnosis. Our engineer arrived at the Alton property and ran through the checks methodically - starting with the most common causes and working toward the more complex.

The appliance rather than the socket

In most cases, a socket that appears dead is actually fine. The appliance plugged into it has failed, or the fuse inside the plug has blown. The quickest way to check is to plug something you know works into the suspect socket. A lamp is ideal because it gives you an instant yes or no. If the lamp lights up, the socket is live and the original appliance is the problem - not the wiring.

In this Alton property, the lamp didn't work either. So the socket itself - or the circuit feeding it - was the issue.

A tripped breaker at the consumer unit

The next check is the consumer unit - what most people still call the fuse box. Modern consumer units use residual current devices (RCDs) and miniature circuit breakers (MCBs) that trip automatically when they detect an overload or a fault. One tripped breaker can knock out every socket on an entire circuit, which is why it can look like several sockets have failed simultaneously even though only one thing went wrong.

In this Hampshire property, the consumer unit was in the hallway - a typical location in homes of this era. All the breakers appeared to be in the on position at first glance, but our engineer noticed one was sitting fractionally proud of the others. That's a classic sign a breaker has tripped and been pushed back without the underlying fault being cleared. A breaker that keeps tripping is telling you something. Resetting it without investigating only delays the problem.

A loose or degraded connection inside the socket itself

When our engineer ran a check using the Voltrade GoFIX diagnostic tool, it flagged a resistance reading on the ring circuit pointing to a poor connection somewhere on the loop. Removing the socket faceplate confirmed it: one of the terminal screws had worked loose, and repeated arcing at that loose connection had scorched the back of the plastic housing.

This type of fault is particularly common in Alton properties built between the 1960s and 1990s. Older socket terminals used a single screw clamp to hold the wire in place, and these can work loose over time - especially in sockets that see heavy daily use or in rooms where temperatures fluctuate. Each time current passes through a poor connection it generates heat. That heat further degrades the contact, and eventually the socket fails. The process can take months or years before it reaches the point of complete failure.

How the Problem Was Resolved

Once the fault was located, the repair moved quickly. The damaged socket was replaced with a new double socket - fully compliant with British Standard BS 1363 - and the connections on the adjacent sockets on the same ring circuit were checked and tightened while our engineer was already on-site. Catching neighbouring connections in poor condition and addressing them at the same visit is standard practice, not an upsell.

Replacing the socket and walking away isn't enough. After any repair to a ring circuit, the circuit needs to be tested - loop impedance, ring continuity, and insulation resistance - to confirm everything is operating within safe limits. Our engineers carry the test equipment to do this on every job, and the results are documented for the homeowner's records. That documentation matters when you come to sell the property or make an insurance claim.

It's also worth being clear about the regulatory side. Electrical work in a domestic property in England and Wales falls under Part P of the Building Regulations. Work that's notifiable under Part P must be carried out by a registered competent person - typically a registered electrician - or the homeowner must notify the local authority building control before work starts. Our engineers are Part P registered, so certification is included as part of every job.

The homeowner also had an older single socket on the same wall that had not been touched in years. Our engineer flagged it during the visual inspection: the connections were showing the same early signs of heat damage as the socket that had just failed. Replacing it during the same visit made sense - the alternative would have been another call-out within months when it eventually gave up entirely.

What This Cost and How Long It Took

The job took just under two hours from arrival to completion, including the initial diagnostics, two socket replacements, and the final circuit tests. For work of this type in Alton and across Hampshire, costs typically break down as follows:

Call-out and initial diagnostic: typically between 60 and 100 pounds, depending on time of day and location
Socket replacement - single or double: commonly between 80 and 150 pounds per socket, parts and labour included
Ring circuit fault finding and repair: typically 150 to 300 pounds for a standard residential fault
Circuit testing and certification: often included in the overall job cost, but worth confirming when booking

The total for this job came to around 220 pounds. That's a reasonable mid-range figure for this kind of fault. A single socket swap on a clearly identified fault - where no extended tracing is required - typically sits at the lower end, around 100 to 130 pounds all in. A fault that needs tracing across multiple locations, or where older wiring requires additional attention, will sit toward the upper end of the range or beyond it.

Emergency call-outs, out-of-hours work, or jobs in properties with particularly old installations will carry additional cost. Always ask for a fixed quote or a clear labour rate before work starts so there are no surprises.

How to Spot the Same Issue in Your Home

Not every socket fault announces itself with a complete failure. Many develop gradually, and there are signs worth watching for before things stop working entirely.

Warning signs you should not ignore

If any of these apply to a socket in your Alton home, get it looked at - don't wait for it to fail completely:

The socket feels warm or hot to the touch when appliances are plugged in
There's an occasional burning or plastic smell near the socket, even if it comes and goes
Scorch marks or discolouration around the socket outlets or on the faceplate surface
The socket is intermittent - it works sometimes but not consistently with the same appliance
Appliances seem to be running slightly below normal power - a lamp dimmer than usual, a charger slower than expected
The socket faceplate is wobbly or not sitting flat against the wall

Checks you can safely do yourself

There are a few things a homeowner can check safely without touching any wiring. Work through these in order:

Test with a known-good appliance. Plug a lamp or phone charger you know is working into the dead socket. If it works, the socket is live and the problem is with your original appliance or its plug fuse.
Check the plug fuse. Plugs in the UK use a cartridge fuse - typically 3A or 13A - fitted inside the plug body. These do blow, particularly on older appliances. A replacement fuse from any hardware shop costs pennies and takes seconds to swap.
Check the consumer unit. Open the cover and look for any breakers in the off position, or sitting fractionally out of line with the rest. If one has tripped, try switching it back on. If it immediately trips again, or trips again within a short time, stop resetting it and call a registered electrician.
Check nearby sockets on the same wall or room. If a cluster has failed rather than just one, you're most likely looking at a circuit-level fault rather than a single socket problem. That narrows things down and gives the engineer useful information before they arrive.

Stop there. Anything beyond these checks - removing faceplate screws, poking at wiring, using a screwdriver to test live connections - is work for a registered electrician. In the UK it's not just about the risk of a shock, though that risk is real. Incorrect electrical work can invalidate your home insurance, fail a buyer's survey when you come to sell, and in certain cases carries personal legal liability.

Lessons - What Every Alton Homeowner Should Know

The homeowner in Alton did most things right. They didn't keep forcing different appliances into the faulty socket, they didn't try to open the faceplate themselves, and they called a professional once the basic checks hadn't resolved the problem. That's the correct sequence, and it meant the repair was clean with no additional damage to deal with.

In hindsight, there were earlier signs they'd half-noticed but not acted on. The socket had been intermittent for a few weeks before it failed completely - occasionally needing the appliance to be repositioned to make contact. They'd assumed it was a loose plug rather than a degraded connection inside the socket. That's an easy and understandable assumption, but it's worth knowing that persistent intermittent behaviour in a socket is almost always the socket, not the appliance. Plugs don't develop intermittent faults on their own - terminals do.

Older homes need periodic electrical checks

Many properties in Alton and across rural Hampshire were built several decades ago, and the electrical installations in some of them have not been inspected since they were first put in. The Institution of Engineering and Technology recommends that domestic electrical installations are inspected and tested every ten years as a minimum - and more frequently if you've bought the property second-hand or if it's been rented out.

An Electrical Installation Condition Report (EICR) typically costs between 150 and 300 pounds for a standard home, depending on size and how many circuits need testing. It gives you a full picture of the installation's condition: not just failing sockets, but brittle wiring, missing earth connections, outdated consumer units without proper RCD protection, and circuits that are undersized for modern electricity demand. In homes like this, those findings are common and worth catching early.

Don't rely heavily on extension leads long-term

One contributing factor in many socket faults is sustained overloading. Ring circuits in UK homes are typically rated at 32 amps total. That sounds generous, but a combination of electric heaters, kitchen appliances, and multiple devices running through a multi-gang extension lead daisy-chained into a single socket can push a circuit hard. Overloading doesn't always trip the breaker immediately - it can cause sustained heat build-up at the weakest connection point on the circuit.

If you're running a home office, a workshop, or a heavily used room from a single socket via extension leads, it's worth having an electrician look at adding a dedicated circuit or additional sockets rather than depending on extensions as a permanent solution. The cost of adding two or three extra sockets is typically between 200 and 400 pounds. That's considerably less than the cost of a fault that's been developing unnoticed for years.
