Repair or Replace Commercial Kitchen Equipment? An Engineer's Guide
A broken combi, fridge or dishwasher forces a fast decision: pay to fix it, or spend more and replace it. Get it wrong and you either pour money into a dying machine or scrap one with years left in it. Five factors settle it, and an honest engineer's assessment usually makes the answer clear.
Quick answer
There's no single rule, but five factors decide it. Weigh them in this order:
- Repair cost vs replacement cost — the working guide is the 50% rule. If a repair comes to more than half the price of a like-for-like replacement, replacing usually wins.
- Age against expected service life — most commercial equipment is built for 10 to 15 years. A fault at year three is worth fixing; the same fault at year twelve rarely is.
- Breakdown history — a first failure is one thing. A third callout on the same machine in a year is the equipment telling you it's near the end.
- Parts availability — once a manufacturer discontinues parts, every future repair gets slower and dearer. Obsolete parts push the decision toward replacement.
- Efficiency and compliance — older refrigeration on R404A is being phased down under F-Gas, and ageing kit burns more energy. Both shift the maths toward new.
Work it out before you decide
Before you commit either way, get the real numbers in front of you:
- Get a firm repair quote — parts, labour and a realistic prognosis. A good engineer will tell you whether a repair buys you years or weeks.
- Price a like-for-like replacement — include delivery, installation, disposal of the old unit and any gas or electrical connection, not just the headline price.
- Add up the downtime — lost covers, agency cover, spoiled stock and the knock-on to service. A cheap repair that keeps failing costs more than its invoice.
- Check the service history — equipment kept on a planned maintenance schedule usually justifies repair. Neglected kit often doesn't.
- Confirm parts and refrigerant status — ask whether parts are still supported and, for refrigeration, what refrigerant the unit runs.
⚠️When replacing is the clear call
Some findings settle it. Lean toward replacement when you see:
- A repair quote over half the replacement price — you're paying most of the cost of new on a unit that's already aged.
- R404A refrigeration with a major fault — the refrigerant is being phased down under F-Gas, so gas is scarce and dear, and a serious leak can make repair uneconomic overnight.
- Repeated failures on the same machine — three or more callouts in a year rarely turns around.
- Obsolete or unavailable parts — if the part is on long lead or no longer made, the next breakdown could leave you down for weeks.
- A failed safety check — gas equipment that can't be brought back to a safe standard has to be replaced.

Is it worth repairing commercial catering equipment?
Often, yes. Equipment under about eight years old with a good service history and available parts is usually worth repairing, especially when the fault is a single component. The picture changes with age, repeated faults and discontinued parts.
What's the rule of thumb for repair or replace?
The common guide is the 50% rule: if the repair costs more than half the price of a like-for-like replacement, replacing usually makes more sense. Treat it as a starting point rather than a hard line, because age, reliability and energy use all move it.
How long should commercial kitchen equipment last?
With proper servicing, most commercial equipment runs 10 to 15 years. Refrigeration and warewashers often sit at the lower end in hard-water, heavy-use Kent kitchens; well-maintained cooking equipment can go longer. A planned maintenance schedule is the single biggest factor in reaching the top of that range.
Do I have to replace old refrigeration because of F-Gas?
Not automatically, but it's a growing factor. Equipment running R404A is affected by the F-Gas phase-down, which makes that refrigerant scarcer and more expensive. If such a unit develops a significant leak or compressor fault, replacing it with a modern low-GWP system is often the better call.
Can you supply and install a replacement if a repair isn't worth it?
Yes. As part of Advantage Catering Equipment, we specify, supply and install replacement equipment as well as repair it, so you get an impartial view and a route to either outcome. Call 01304 873469 to talk it through.
