Before You Switch the Heating Back On: An End-of-Summer Electrical Check

There’s a very specific sound that marks the end of a British summer. It’s not the last ice cream van of the season or the first person moaning about Christmas adverts. It’s the click of a portable heater being pulled out of the loft, plugged straight into the nearest socket, and switched on without a second thought — for the first time since April.

We get it. Bank holiday’s done, the evenings are drawing in, and nobody wants to think about their consumer unit when there’s a jumper to find. But that heater has spent five months getting dusty, possibly damp, and definitely forgotten about. Before you fire it up, it’s worth thirty seconds of attention.

Why “it worked fine in March” isn’t good enough

A heater doesn’t fail because it’s old. It fails because something changed while nobody was looking — a chewed cable in a box of Christmas decorations, a socket that’s had furniture pushed against it all summer, a plug that got left in a damp shed. None of that shows up until you switch the thing on and ask it to draw a full load for the first time in months.

Electrical Safety First’s guidance on portable heaters is blunt about this: most heater fires come down to basic mistakes, not faulty products. Which is actually good news, because basic mistakes are the easiest thing in the world to avoid once you know what you’re looking for.

The pre-season check

Look before you plug in

Uncoil the cable fully and run your eye — and a hand — along its whole length. Cracked insulation, a squashed section, or a plug that rattles when you shake it are all reasons to stop, not reasons to “just try it once.”

Never on an extension lead

Heaters draw a lot of current. Extension leads and multi-socket adaptors aren’t built to carry that load continuously, and this is one of the most common causes of overheating we see. Plug it straight into a wall socket, every time.

Give it space

Keep it at least a metre from curtains, sofas, bedding and anything else that burns. Stand it on a flat, solid surface — not on carpet, not on a stack of magazines — where it can’t be knocked over.

Don’t dry clothes on it

We know the temptation the first cold, damp week of the year brings. Resist it. Drying laundry on or near a heater is one of the most consistent causes of house fires this time of year.

Never leave it running unattended

Not overnight, not while you nip out, not while you fall asleep on the sofa. If you need background heat while you sleep, that’s a job for your central heating, not a portable heater.

While you’re doing the rounds: press the test button on every smoke alarm in the house. Batteries fade quietly over a summer nobody was thinking about them, and this is the moment they get remembered.

When it stops being a checklist

If a plug feels hot to touch, if there are scorch marks around the pins or the socket faceplate, if you smell burning or hear buzzing from a switch — stop. Do not plug that heater in again. Do not reset a breaker that keeps tripping and hope it holds this time. A breaker that trips repeatedly is doing exactly what it’s designed to do: telling you something downstream is wrong. Get it looked at before you rely on that circuit again.

If your home hasn’t had a proper electrical inspection in years, an EICR will catch the tired wiring, loose connections and overloaded circuits that a visual check can’t — before they become a heater-shaped reason to call us at 2am.
