Repair vs Replace: Simple Rules for Deciding What to Do with Your Appliance

Got a noisy boiler or a dishwasher that won’t start? Before you rush out to buy a brand‑new unit, ask yourself three quick questions: How old is it, how much will fixing it cost, and how reliably does it work now? Answering these will tell you if a repair makes sense or if it’s time to replace.

Age and Expected Lifespan

Most appliances have a typical lifespan. A gas boiler usually lasts 10‑15 years, a kitchen extractor fan 7‑10 years, and a freezer about 10‑15 years. If your device is past the midpoint of that range, parts start to wear out faster and future breakdowns become more likely. For example, a 12‑year‑old boiler that’s already needed two major fixes is a strong candidate for replacement.

But age alone isn’t the whole story. Good maintenance can push a boiler’s life well beyond 15 years. Regular service by a certified engineer keeps the heat exchanger clean and the safety checks up to date. So, a 14‑year‑old boiler that’s been serviced yearly might still be worth repairing if the fault is minor.

Cost of Repair vs Cost of New

Rule of thumb: if the repair bill is more than 50 % of the price of a comparable new unit, replacement is usually smarter. A broken oven heating element might cost £80 to fix, while a new oven runs about £600 – fixing is the clear win. On the other hand, a cracked gas valve on a boiler can run £350 or more; a new boiler installation can be £2,000‑£3,000, so you need to weigh the long‑term savings on energy bills too.

Don’t forget hidden costs. An old appliance may be less energy‑efficient, meaning higher running costs. Upgrading to a modern, high‑efficiency model can lower your gas or electricity bill by 15‑30 %. When you add those savings over a few years, replacement often pays off faster than you think.

Reliability and Safety

Safety is a non‑negotiable factor. A leaking gas boiler or a faulty water heater can be hazardous. Even if the repair price looks reasonable, a compromised safety system should be replaced outright. The same goes for appliances that cause mould or poor indoor air quality, like a non‑working extractor fan – the health risks outweigh the repair cost.

Reliability matters for daily convenience. If your fridge is making strange noises and the temperature is inconsistent, you’ll be constantly checking food. A repair might get it working for a few months, but you’ll likely face another breakdown soon. In those cases, a new fridge gives you peace of mind.

When to Call a Pro

Any gas‑related work should be handled by a Gas Safe registered engineer. Trying to fix a boiler yourself can void warranties and breach safety regulations. At Bedford Gas Appliance Repair Services we can give you a clear quote, explain the fault, and recommend whether repair or replacement makes the most sense for your home.

If the issue is electrical – like a kitchen extractor fan motor that’s burnt out – a qualified electrician or appliance technician should take a look. DIY fixes are fine for simple things like cleaning a filter, but once you’re dealing with wiring or gas connections, call the experts.

Bottom Line Checklist

• Check the appliance’s age and typical lifespan.
• Get a repair estimate and compare it to the price of a new model.
• Factor in energy efficiency and running costs.
• Consider safety – any gas leak or electrical fault should push you toward replacement.
• Consult a certified professional for an honest assessment.

Following this checklist helps you avoid costly mistakes and keeps your home running smoothly. Whether you end up repairing a dishwasher or installing a brand‑new boiler, the right decision saves you time, money, and worry.
