Tunbridge Wells has a lot of period housing, and with older homes often comes older wiring that was perfectly fine by the standards of its time but has not aged well. Unlike a leaking roof or a damp patch, electrical faults are mostly hidden behind plaster and skirting boards, so the warning signs are easy to miss until something goes wrong. Here are seven worth paying attention to.
1. An Old Fuse Board With Ceramic Fuses
If your consumer unit still uses rewirable ceramic fuses rather than modern circuit breakers, that alone is a strong indicator the wiring is due an overhaul. Ceramic fuse boards were largely phased out decades ago in favour of units with RCD and RCBO protection, which cut power far more quickly in the event of a fault and offer much better protection against electric shock.
2. Frequent Tripping With No Obvious Cause
Occasional tripping linked to a specific faulty appliance is not unusual. Frequent, unexplained tripping across different circuits, especially if it has started happening more often over time, usually points to a deeper problem with the wiring itself rather than any one device. If everything goes off at once and your neighbours are affected too, check for a local power cut before assuming it is your wiring. To narrow down the cause, try our tripping fault finder.
3. Warm or Discoloured Sockets and Switches
A socket or switch that feels warm to the touch, or shows brown or black discolouration around the edges, is a genuine warning sign, not a cosmetic issue. It usually indicates a poor connection generating heat, which can be a fire risk if left unaddressed.
4. Flickering Lights Unrelated to the Bulb
If you have already replaced the bulb and lights still flicker, particularly if it happens when other appliances switch on, it can indicate a loose connection or an overloaded circuit rather than a simple bulb fault.
5. A Persistent Burning Smell Near Outlets
Any burning smell near a socket, switch or the consumer unit should be treated seriously. Switch off the affected circuit at the consumer unit if you can do so safely, and get it inspected before using that circuit again.
6. Rubber-Insulated or Cloth-Covered Cabling
If you have ever seen the wiring in a loft or under floorboards and it is wrapped in black rubber or a woven cloth-like sheath rather than modern PVC, that is a strong sign the installation dates from before the 1970s. This kind of insulation becomes brittle with age and is at much higher risk of failure.
7. Not Enough Sockets for Modern Use
This one is not a safety fault on its own, but it is often a symptom of the same underlying issue. Homes wired decades ago were designed around far fewer electrical appliances than a modern household uses. Relying heavily on extension leads and multi-way adaptors because there are simply not enough sockets is a sign the original circuit design has not kept pace, and it is worth having the whole installation properly assessed rather than just adding more adaptors.
What to Do If Several of These Apply to You
Recognising one or two of these signs does not automatically mean you need a full rewire, but it is a good reason to get the installation properly assessed. The most reliable way to do that is an EICR, which gives you a documented, classified report on exactly what condition the wiring is in, rather than a guess based on visible symptoms. If the report does point to significant issues, the next question is usually whether you need a full or partial rewire, which we cover in full rewire versus partial rewire: how to know which you need.
What a Rewire Involves and What It Costs
If a rewire is the right next step, it is worth understanding what is involved before booking a survey. Our guide to house rewiring cost in Kent breaks down pricing by property size, and how long does a house rewire take covers what to expect during the work itself, including whether you need to move out.

If any of these signs sound familiar, the safest next step is a proper inspection rather than waiting to see if things get worse. We carry out rewiring and EICR assessments across Tunbridge Wells and the wider Kent area. Get in touch for a free, no-obligation visit.
