An appliance stops working and a repair quote arrives. The instinct is to compare the repair cost against the price of a new one, which is the wrong comparison — it ignores how much life is left in the machine you have.
The better question is what the repair buys you in remaining service, and whether that is worth the money against starting a new lifespan.
What changed in 2026
- Right-to-repair rules expanded. Requirements around parts availability and repairability improved in several markets.
- Parts availability improved unevenly. Mandated availability periods helped for newer appliances and less for older ones.
- Electronic control failures stayed common. Increasingly complex controls remained a frequent failure point with expensive parts.
- Energy efficiency gains slowed. The running-cost argument for replacing a working appliance weakened as efficiency improvements plateaued.

The useful comparison is where a specific machine sits within its range. An appliance in its first third with a component failure is worth repairing. One past its expected life is on borrowed time regardless of what you fix.
The decision framework
Compare repair cost against remaining expected life, not against a new appliance.
A repair costing a moderate amount on a machine with most of its life ahead is straightforwardly worthwhile. The same repair on a machine near the end of its expected life buys uncertain time, because whatever fails next is also due.
A commonly used heuristic: if the repair costs more than roughly half the price of a comparable replacement, and the appliance is past halfway through its expected life, replacement usually wins. Neither condition alone is decisive.
Consider which component failed. Some failures are cheap and isolated; others indicate the machine is wearing out generally.
Cheap and isolated: seals, hoses, belts, filters, thermostats, door switches.
Expensive or terminal: compressor, motor, drum bearings, control board, heat exchanger.
A control board failure is particularly awkward — the part is expensive, and on an older machine it may no longer be available at all.
Check parts availability first. A repair is not possible if the part does not exist. Manufacturers have obligations to supply parts for a period after production, and past that period availability becomes uncertain.
Getting a useful quote
Ask whether the diagnosis fee is credited against the repair if you proceed. Most reputable repairers do this, and it changes the cost of finding out.
Ask what failed and why. A repairer who can explain the failure and whether it indicates broader wear is giving you the information the decision needs.
Ask about the warranty on the repair. A repair guaranteed for a period is worth more than one that is not.
Get the model and serial number and check for known issues or recalls before booking. Some failures are common enough to have a documented fix, and some are covered by extended manufacturer programmes even outside warranty.
Check whether the appliance is still within a warranty period, including any extended cover taken at purchase — see warranty registration and how to win a warranty claim.
Common mistakes
- Comparing repair cost only against a new price. Ignores remaining life.
- Replacing over one cheap early failure. Frequently a simple fix.
- Not checking parts availability. Determines whether repair is possible.
- Not asking whether the diagnosis fee is credited. Changes the cost of finding out.
- Ignoring the warranty. Some failures are covered.
- Replacing a working appliance for efficiency. The gains rarely justify it.
- Skipping maintenance. Filters and seals extend life substantially — see filter replacement schedule.
FAQ
Is it worth repairing an appliance past its expected life?
Sometimes, for a cheap isolated fix on a machine you otherwise like. For an expensive repair, the odds favour replacement, because other components are also at end of life.
Do extended warranties help?
Frequently less than the price suggests, because statutory rights already cover inherent faults for a period. Read what the cover adds beyond that baseline — see how to win a warranty claim.
How much does maintenance extend life?
Meaningfully for anything with filters, seals, or descaling requirements. Neglected maintenance is a common cause of premature failure and is entirely avoidable.
Should I buy the extended-life model?
Higher build quality frequently does last longer, and the premium is not always justified. Repairability and parts availability matter as much as initial quality.
