Looking after your home appliances: the UK maintenance guide (2026)
On this page
Keeping home appliances in good shape is mostly straightforward — for most of them, it means a monthly clean and an occasional descaling tablet rather than a professional call-out. The exception is your boiler, which genuinely needs an annual check by a qualified engineer, and where skipping it has real financial and safety consequences.
Here's a clear breakdown of what each appliance type needs, and how often.
Why maintenance matters
A well-maintained appliance runs more efficiently, lasts longer, and is less likely to fail inconveniently. There's also a practical financial reason: neglecting maintenance is one of the most common ways to void a manufacturer's warranty. Missing required annual services, using the wrong cleaning products, and failing to register an appliance on time are the top causes of refused warranty claims — see what voids an appliance warranty for the full picture.
Maintenance intervals at a glance
| Appliance | Professional service? | Frequency | Key maintenance tasks |
|---|---|---|---|
| Boiler (gas) | Yes — Gas Safe engineer | Annually | Check pressure monthly; keep service record |
| Gas cooker / hob | Recommended | Annually | Clean burners regularly |
| Washing machine | No | — | Descale every 1–3 months; maintenance wash monthly; clean filter monthly |
| Dishwasher | No | — | Clean filter monthly; descale monthly; wipe door seal |
| Tumble dryer | No | — | Clean lint filter every use; check vent duct annually |
| Fridge / freezer | No | — | Vacuum condenser coils every 6–12 months; check door seals |
| Electric oven | No | — | Regular cleaning; replace door seal if damaged |
| Cooker hood / extractor | No | — | Clean or replace filters monthly to quarterly |
Gas appliances: the one professional requirement
Annual boiler servicing is the standout case in home appliance maintenance. Gas Safe Register — the official UK register for gas engineers — recommends having your boiler serviced once a year by a registered engineer. Most manufacturer warranties require this as a condition of cover.
What gets checked during a service isn't just a quick look — it includes combustion analysis, flue inspection, heat exchanger cleaning, and testing all safety cut-out devices. For the full detail, see what does a boiler service include?
If you have a gas hob or gas cooker, an annual check is also recommended. All gas work in the UK must be carried out by an engineer on the Gas Safe Register — it's a legal requirement.
Washing machines and dishwashers
Neither appliance needs professional servicing under normal use, but both benefit considerably from basic regular care.
Washing machine:
- Run a hot maintenance wash (60–90°C with a drum-cleaning tablet) once a month.
- Clean the rubber door seal — it's a common place for mould to accumulate.
- Clean the filter every month, especially if you wash items with tissues or pet hair.
- Descale every one to three months, particularly in hard-water areas.
Dishwasher:
- Clean the filter weekly or monthly depending on how often you use it.
- Run a descaling cycle monthly.
- Wipe the door seal regularly to prevent mould.
These steps alone extend the typical working life of both appliances significantly.
Tumble dryers: a safety point
Tumble dryer fires are more common than people assume, and lint is almost always the cause. Clean the lint filter every use — not every few uses, every use. Check the vent duct or heat-pump condensate tray regularly for blockage. Never leave a tumble dryer running unattended.
Fridges and freezers
Generally maintenance-free in the sense that no professional visit is required, but worth vacuuming the condenser coils (usually at the back or underneath) every six to twelve months. Dust and pet hair on the coils make the compressor work harder and shorten the appliance's life. Check door seals periodically — a failing seal wastes energy and shortens the compressor's life too.
How JustTaggit helps
The maintenance tasks themselves aren't complicated. The challenge is remembering that the last boiler service was fifteen months ago rather than twelve, or that you haven't descaled the washing machine since it was installed. JustTaggit lets you store service records and notes against each appliance's QR code, and set reminders before the next service is due. Scan the code on the appliance to see when it was last serviced, where the manual is, and what the warranty expiry date is.

Frequently asked questions
Which home appliances need professional servicing?
In most homes, only gas appliances: the boiler (annually) and, if you have one, a gas cooker or hob (annually recommended). All other common white goods — washing machines, dishwashers, fridges, tumble dryers — don't require professional servicing under normal use.
How much does a boiler service cost in the UK?
Typically £80 to £120 for a standard annual service, though prices vary by region and engineer. Some energy suppliers and home cover plans include an annual service as part of the package.
Does regular maintenance actually extend appliance life?
Yes. Descaling a washing machine regularly, for instance, prevents limescale from coating the heating element — the most common cause of early failure in hard-water areas. The same principle applies across most appliances: small regular tasks prevent the build-up that causes expensive faults.
Do I need to keep appliance service records?
For gas appliances, yes — most boiler warranties require proof of annual servicing. For other appliances, records aren't usually required, but they can support a warranty claim and are useful when selling the property or appliance.
