A £30 kettle dies. A £45 toaster starts smoking on setting three. A £60 blender refuses to spin. In each case there is a decision: pull the plug and buy a new one, or spend an hour trying to fix it. The default in most flats is to bin, then buy. That is often wrong, sometimes right, and this guide explains which situation you are in without romanticism about repair or defeatism about waste.
The frame this article uses is honest cost including your time, not moral posture about consumption.
The 50 percent rule
The rule most repair professionals use, and the one worth memorising:
- If total repair cost (parts plus labour) is under 50 percent of a like-for-like replacement, repair.
- Between 50 and 70 percent, it depends on the age of the appliance, the reliability of the model, and whether a comparable replacement would ship in plastic across an ocean.
- Above 70 percent, replace unless the appliance has real specific value (a discontinued model, a durable body you already like, a fault confined to a plug or cable).
Cable and plug faults deserve a note. On any appliance with a UK moulded plug, replacing the whole cable set costs £4 to £10 and takes 10 minutes. That is the single most repairable fault on any small appliance and should almost never lead to disposal.
The five-minute diagnosis
Before deciding, spend five minutes on this sequence with the appliance unplugged:
- Check the cable full length for kinks, scorching, or a wobbly plug. Cable faults are the most common small-appliance failure.
- Check the base plate on kettles and toasters for corrosion or bulging. Bulged plastic around a heating element means the appliance is done.
- For anything with a motor (blender, hand mixer, food processor), listen at the base: a low hum with no spin usually means a seized shaft, often fixable by cleaning; a burning smell means the motor is done.
- Test the socket with a lamp before assuming the kettle is dead. Half of “broken kettle” cases are dead sockets.
The five-minute diagnosis kills roughly a third of repair jobs before they start (the socket was fine, actually) and steers the remaining two-thirds toward the right decision.
Where to actually get things fixed
Three routes, in rough order of ease:
- Repair Café / Restart Party events. Free or donation-based volunteer-run repair sessions, usually monthly, in most European cities and a growing US network. Bring the appliance and cable. Best for kettles, toasters, small motor appliances, lamps.
- Manufacturer spares. Bosch, Dualit, KitchenAid, Vitamix all sell direct-to-consumer spare parts. Dualit toasters in particular are designed to be repaired and a heating element is under £15.
- Independent local electrical repair. These exist in every city despite feeling extinct. Search “small appliance repair” and the postcode; call ahead to confirm they still take kettles and toasters, not just professional kit.

Category by category, honest guidance
What is worth trying to repair versus what is usually done:
- Kettle. Cable fault, base plate corrosion, and thermal cutout are all fixable. A cracked body or scorched internal wire is not. Rule of thumb: repair up to £15 on a £30 kettle.
- Toaster. Heating element, timer, and eject spring are all replaceable on models designed for it (Dualit, higher-end Bosch). On cheap sealed toasters (Argos own-brand, most under-£30 models) internal access is destructive; replace.
- Blender. Motor and coupler are the failure points. On stick blenders under £50 the internal architecture usually rules out repair. On jug blenders over £100 (Vitamix, Ninja), parts are widely available and repair pays.
- Hair dryer. Cable, switch, and airflow filter are cheap fixes. Motor and heater failure often mean replacement.
- Microwave. Do not open. Capacitors hold lethal charge. Repair only via qualified engineers; usually not worth it below £150 new price.
Quick reference: repair or bin
| Fault | Verdict |
|---|---|
| Cable damage on any appliance | Repair. £4 to £10 for a moulded cable set. |
| Kettle base plate corroded but body intact | Repair or Repair Café. £5 to £15 parts. |
| Toaster carriage stuck, no burning smell | Repair, spring is £3. |
| Blender under £50, motor humming without spin | Diagnose free at a Repair Café; often replaceable coupler. |
| Microwave that trips the breaker | Replace. Do not open. |
| Cracked plastic body around live parts | Replace, recycle at council WEEE point. |
The waste dimension
Small appliances are the fastest-growing WEEE stream in the UK and EU. Kettles, toasters, hair dryers, phone chargers, and cables collectively hit around 500,000 tonnes a year across Europe. Most is landfilled or sent for shredding rather than actual reuse. A kettle repaired for £10 avoids roughly 1.5 kg of new plastic-metal composite reaching the waste stream. It is not the biggest lever anyone will pull in the year, but it is a real one, and it is cheap.
The honest position: sometimes replacement is correct, sometimes repair is correct, and the five-minute diagnosis plus the 50 percent rule tells you which. What is almost never correct is skipping the diagnosis and defaulting straight to replacement.
The consumer rights angle nobody uses
UK consumer law (Consumer Rights Act 2015) says goods must be of “satisfactory quality” for a reasonable period, which for small appliances typically means 3 to 6 years, not just the manufacturer’s 12-month warranty. If a £120 stand mixer fails at 18 months and there is no evidence of misuse, you have a legitimate claim against the retailer, not the manufacturer, for repair, replacement, or partial refund. Most people never pursue this because the process feels intimidating. The letter-of-request template on Which? and Citizens Advice takes 10 minutes and works surprisingly often; even a claim politely made without escalation is frequently resolved with a goodwill repair or partial credit.
The satisfaction data
Restart Project post-event surveys show something the pro-repair movement rarely highlights: participants report high satisfaction not because the appliance was fixed, but because they learned what was wrong with it. Half the value of a Repair Café visit is diagnostic. Even the appliances that turn out to be unfixable leave with an owner who knows what to look for when buying the replacement, which shifts future purchases toward better-designed products.

Frequently asked questions
If the total repair cost (parts plus labour) is more than 50 percent of a like-for-like replacement price, replace. The exception is anything that would go to landfill immediately after, in which case the environmental case for repair strengthens even at 60 to 70 percent.
Yes, especially for anything with a heating element, motor, or cable fault. UK Restart Project data suggests roughly 40 to 60 percent of appliances brought to repair events leave working, and the visit itself teaches you which faults are easy to diagnose next time.
When the fault involves the mains cable, an internal short, or any water-adjacent electrical component in an old appliance. If the plastic body is cracked around a live element, the appliance is done. Do not open a microwave; capacitors hold lethal charge long after unplugging.
For products under £80, extended warranties usually cost more than the replacement risk. For products above £150 with a known reliability issue (early laptop keyboards, some tumble dryer drums), they can be worth pricing. Read the exclusions before the sales pitch.
