Small appliances: fix, fuse or farewell?
Nobody calls an engineer for a £30 kettle, and the engineer would tell you not to. Small appliances live by different rules: a plug fuse everyone forgets, limescale that murders elements, and a bin they must never end up in. Two checks stand between yours and the recycling centre.

The forgotten fix: the plug fuse
Every UK plug carries a small ceramic fuse, and when an appliance dies without drama, no bang, no smell, no half-life, that fuse is the first suspect. It exists to sacrifice itself, and sometimes it does so quietly of old age. A spare 13A fuse costs pennies and belongs in every home emergency kit.
The five-minute fuse check
Unplug the appliance first
Always. The plug comes out of the wall before a screwdriver comes anywhere near it.
Open the fuse carrier
On a moulded plug, a small flathead screwdriver levers out the fuse holder between the pins. On an older rewireable plug, undo the big screw and lift the cover.
Swap in a fuse of the same rating
Like for like: a 13A fuse for kettles and toasters, 3A for lamps and low-power gadgets. The rating is printed on the fuse and usually on the plug. Never fit a bigger one to stop it blowing.
Test in a socket you trust
Use one that already runs something else without complaint, so a dead socket cannot frame an innocent kettle.
If the new fuse blows, stop
A fuse that keeps blowing is protecting you from a real fault. That appliance is done; no third fuse, no bigger fuse.
Fix, fuse or farewell?
Limescale: the serial kettle killer
In hard-water Britain, most kettles do not break, they fur up. Scale coats the element, boiling takes longer and sounds like gravel in a washing machine, and the cut-out starts tripping before the water is properly boiled. The cure costs less than a coffee: descale with a kettle descaler, citric acid or a half-and-half mix of water and white vinegar, left to work, then boiled away with two or three rinses.
Toasters have their own quiet failure mode: the crumb tray. A full tray smokes, sets off alarms and can catch. Unplug the toaster, slide the tray out and empty it monthly, and never fish trapped toast out with a knife while it is plugged in; the elements are live even when it is not toasting.
The honest economics of a £30 appliance
Professional repair rarely makes sense down here: a call-out costs more than most small appliances did new, which is why the trade norms in the repair or replace guide start at washing machines. Binning is not the only alternative, though. Under two years old, the retailer is your first stop, because consumer law covers goods that fail early. Beyond that, a repair café (volunteer-run fixing sessions, found in most towns) will often revive a decent kettle for the price of a donation.

Small appliance rules
Do
- Unplug before fuse checks, crumb trays and descaling
- Keep spare 3A and 13A fuses in the drawer
- Descale the kettle before it starts boiling in slow motion
- Take dead electricals to WEEE recycling or shop take-back
Don’t
- Do not fit a bigger fuse to stop one blowing
- Do not open the casing; there are no user-serviceable parts inside
- Do not rescue toast from a toaster that is still plugged in
- Do not run a kettle from a daisy-chained extension lead
A kettle draws close to the full 13 amps a socket can give, which is why kettles and heaters are the classic overloaders of extension leads. Wall socket, always.
Farewell, done properly
Small electricals are WEEE (waste electrical and electronic equipment) and never go in the household bin: they are a fire risk in the lorry and a waste of recoverable metals. Council recycling centres take them free, many councils collect small electricals at the kerb, and larger retailers offer take-back when you buy the replacement. The kettle did its one job thousands of times; it has earned the proper exit.
Not sure whether it is the appliance or the socket?
Self-Diagnose in the Tickover app narrows it down in a few questions, from plug fuse to house wiring, and tells you when it is time to involve an electrician instead.
Quick answers
What fuse does a kettle or toaster need?
Kettles need a 13A fuse, and most toasters take 13A too; check the rating plate or the moulding on the plug. Lamps and small low-power gadgets take 3A. Always replace like for like: fitting a higher-rated fuse to stop it blowing removes the protection and leaves the flex as the weakest link, which is how cables catch fire.
Why does my kettle take so long to boil?
Limescale, in almost every case. A furred element heats the scale before it heats the water, so boiling takes longer, costs more and strains the cut-out. Descale with citric acid, a proprietary descaler or half-and-half white vinegar and water, leave it to work, then rinse with two or three fresh boils. In hard-water areas, repeat monthly.
Is it worth repairing a kettle or toaster?
Not professionally: an engineer call-out costs several times the price of a new kettle, and the casings are not designed to be opened at home. The checks that are worth it are free: the plug fuse, a different socket and a descale. Beyond that, a repair café gives an out-of-warranty appliance a fair chance, and a retailer handles anything under two years old that failed early.
How do I dispose of a broken kettle or toaster?
As WEEE, never in the household bin. Take small electricals to the council recycling centre free of charge, use a kerbside small-electricals collection if your council runs one, or hand the old one over through a retailer take-back scheme when the replacement arrives. Recycling recovers the metals and keeps a fire risk out of the bin lorry.
