Extension lead, wall power strip or a new socket: which one

The Abimeister team · Updated · 6 min read

Most flats and older houses in Tallinn were wired for far fewer devices than the average household now runs. The result is usually a socket behind the television or under the desk with three or four things plugged into it, one on top of another. There are three honest ways to deal with that: a normal extension lead, a wall-mounted power strip, or a new socket put in by an electrician. Each has a place, and each has a point where it stops being sensible.

Extension lead, wall power strip or a new socket: which one

An ordinary extension lead — quick, but meant to be temporary

A standard extension lead is the right tool when the need is short-lived: a lamp for a weekend, a drill on a landing, a fan in summer. It is cheap, you already have one, and it solves the problem in thirty seconds. The trade-off is that it is designed for exactly that kind of use, not for living permanently behind a sofa with a laptop charger, a router, a lamp and a phone charger all drawing current through it around the clock.

The cable itself has a rating, normally printed on the lead or the packaging, usually somewhere around 10 or 16 amps depending on the model. Cheap leads with thin cores heat up under sustained load, and a warm cable coiled tightly on itself gets warmer still. If the plastic body or the cable feels warm to the touch after an evening's use, that is not something to shrug off.

Extension leads bought as a temporary fix have a way of staying put for years, which is where the risk actually sits. It is not that the lead is unsafe on the day you buy it; it is that nobody replaces it once it becomes part of the furniture.

A wall-mounted power strip — a reasonable middle step

Screwing a power strip to the wall behind a desk or an entertainment unit is a step up from a loose lead trailing across the floor. It tidies the cabling, keeps the strip off the carpet, and if you choose one with a decent cable and a few extra sockets it can comfortably serve a fixed cluster of low-draw devices: a monitor, a router, a lamp, a phone charger.

The strip is still, electrically, an extension lead. Mounting it on the wall does not raise its rating or change how much current it can carry. It also does not change what is on the other end: everything still runs back through the single wall socket it is plugged into, and that socket and the circuit behind it have their own limits regardless of how tidy the strip looks.

This option suits a setup you know will stay roughly the same, with devices that do not draw much: a home office corner, a TV unit, a workbench with hand tools. It is not the right answer once you start adding a space heater, a kettle, or anything else that pulls serious current.

A new socket — right when the load is permanent, not occasional

If a spot in the flat or house is now a permanent hub — a desk with a computer, monitor and heater, a kitchen worktop with a kettle and an air fryer, a workshop corner with power tools — the sensible fix is a socket in the wall, on its own connection back to the consumer unit, sized for what actually sits there. It stops being about routing more cables and starts being about giving that load somewhere proper to go.

A new socket, done properly, does not depend on the condition of a lead you bought years ago or forgot was even plugged in. It is fixed to the wall, wired to the right cross-section of cable for the draw expected, and once fitted you stop thinking about it, which is the point.

We install sockets from 35 € per job, and for anything that touches the wiring itself, rather than just adding a fitting, the work is billed as electrical work from 49 € per hour. A qualified electrician does the job either way, and it comes with our 24-month guarantee on the work.

What happens if you leave an overloaded socket as it is

A socket or lead carrying more than it is rated for does not usually fail with any drama. It runs warm, then warmer, over weeks or months, and the plastic around the pins and the cable insulation slowly degrade under the heat. Discolouration around a plug, a faint smell of hot plastic, or a socket that feels warm to the touch are all worth acting on immediately rather than noting and forgetting.

Panel flats from the Soviet era and older wooden houses in areas like Kalamaja or Nõmme were both wired for a much lighter load than a modern household runs, which makes this more relevant in Tallinn than the number of visible sockets might suggest. The building's wiring behind the wall has its own limits too, separate from whatever lead or strip you plug into it.

None of this means panic over a lamp and a charger sharing a socket. It means treating heat, smell or a scorch mark as a signal to stop using that socket and get it looked at, rather than as background noise.

  • Warm or discoloured plug, socket or extension body
  • A faint smell of hot plastic near a socket or lead
  • A lead or strip that has been in constant use for years without being checked
  • A single socket feeding a heater, kettle or power tools alongside other devices
  • Frequent tripping of the breaker for that circuit

How to decide which option fits your situation

Start with how long the setup will last. If it is genuinely temporary — a device you will move or remove within a few weeks — a good-quality extension lead, used uncoiled and not overloaded, is a sensible and proportionate choice. If it is a fixed arrangement you expect to keep for a year or more, treat it as permanent even if it started as a stopgap.

For a permanent low-draw corner, a wall-mounted power strip is a fair compromise: tidy, cheap, and adequate for a router, a lamp and a couple of chargers. For anything that draws real current on a regular basis — heaters, kitchen appliances, power tools, a home office with several screens — a proper socket, sized and wired for that load, is the only option that removes the risk rather than managing it.

If you are not sure which category your situation falls into, a photo of the socket and a description of what is plugged in is usually enough for us to tell you honestly whether an extension lead is fine or whether it is time for a new socket.

Use an extension lead for anything genuinely temporary, a wall-mounted strip for a fixed low-draw corner, and a proper new socket for any load that is there to stay.
