Buying used kitchen kit

A good second-hand range or fryer can save you thousands - or it can hand you a fire risk, a failed gas inspection and a bill far bigger than the one you thought you had dodged.

The used market is where a lot of catering businesses find their first oven, their spare fryer or a replacement combi when the budget is tight. There is nothing wrong with that. Some of the best-built commercial equipment outlives two or three owners without complaint, and buying pre-owned is often the sensible, frugal choice. The trouble is that a stainless steel shell hides a great deal, and a seller keen to move a unit on will rarely volunteer what is wrong with it. What follows is a plain, ordered way to check a piece of kit before you commit, so the saving stays a saving and does not turn into a call-out, a condemnation notice or worse.

A step-by-step way to check before you buy

Work through these in order. Each one takes minutes, and any single one of them can save you a five-figure mistake.

  1. Ask for the paperwork before you part with a penny. Gas kit should come with a current CP42 commercial catering gas safety record, and any unit holding refrigerant needs its F-gas service history. A genuine seller keeps these; a vague answer or a promise to "sort it later" tells you most of what you need to know.
  2. Verify the engineer, not just the certificate. A certificate is only as good as the person who signed it, so check they hold the commercial catering category on the Gas Safe Register - you can confirm any engineer’s registration free on 0800 408 5500. The Gas Safety (Installation and Use) Regulations 1998 require commercial gas work to be done by a Gas Safe engineer, and a record signed by someone outside that category is worthless.
  3. Check the conformity marks are actually there. Equipment sold in Great Britain should carry a UKCA or CE mark, and gas appliances should state the gas type and pressure they are rated for - propane running at 37 mbar, for instance. If the data plate is missing, painted over or does not match what the seller is telling you, treat that as a reason to walk away rather than a detail to overlook.
  4. Read the refrigerant data plate on any chilled unit. Find the plate inside the door frame or on the rear panel and note the refrigerant type and charge weight. If it reads R404A or R507A and the unit is more than eight to ten years old, you are buying into a refrigerant being phased down under F-gas rules - factor a re-gas or replacement into your sums now, not when it fails in a heatwave.
  5. Inspect the electrical side with your own eyes. Anyone selling used electrical goods is legally bound by the Electrical Equipment (Safety) Regulations 2016 and the General Product Safety Regulations to supply something safe, but do not rely on that alone. Look over the plug, flex and casing for scorching, cracks or bodged repairs, and plan a visual check and a portable appliance test before the kit goes into daily service.
  6. Look past the polished front. The customer-facing steel is usually wiped down for a sale; the truth lives at the back, underneath and inside. Pull the unit out where you can, check the burners, seals, door hinges and the grease-laden guts of any canopy or fan, and lift the filters on extraction kit to see what decades of frying have left behind.
  7. Budget for commissioning and a proper clean. Assume every used unit needs installing, testing and certifying by a competent engineer before you cook on it, and assume anything from the extraction line arrives caked in old grease. Building those costs into your offer keeps the negotiation honest and stops a "bargain" quietly becoming an expensive one.

Where the real risk hides

The headline danger with second-hand catering equipment is not that it looks tired. It is that it can be quietly dangerous in ways the untrained eye never sees. A gas range with a poor conversion or a leaking joint can put carbon monoxide into your kitchen; a fryer with worn thermostats can overshoot; and an extraction canopy that has spent years pulling grease-laden air will carry a heavy deposit of exactly the fuel that turns a small flare-up into a serious fire. When you buy a used unit, you are also buying its history of neglect - and grease is cumulative. None of that shows up in a photograph or a quick showroom wipe-down.

Refrigeration deserves its own moment of caution. Beyond the refrigerant question, a used fridge or blast chiller has to actually hold temperature reliably, because the law does not care that the unit was cheap. Chilled food must be kept at 8°C or below and hot food held at 63°C or above, and your Hazard Analysis and Critical Control Points plan will assume the equipment can deliver that day in, day out. A compressor on its last legs will pass a ten-minute demonstration and fail you a fortnight later, so ask to see it running from cold and ask when it was last serviced.

It is worth remembering who carries the risk once the money changes hands. Under the Health and Safety at Work etc. Act 1974 the duty to provide safe equipment sits with you as the employer, and the penalties for getting it wrong are not trivial - unlimited fines and, in serious cases, custodial sentences. That is the real reason to slow down and check. A used-kit disaster is rarely just a repair bill; it is often a fire, an insurance dispute and a business interruption rolled into one. We have set out the true scale of that in the cost of getting fire safety wrong, and it makes sobering reading for anyone tempted to skip the checks.

If a used canopy or fryer arrives coated in someone else’s grease, have it stripped and certified before first use with a commercial kitchen deep clean.

Bringing used kit safely into service

Buying well is only half the job. The moment a second-hand unit lands in your kitchen it becomes part of a working system - the gas supply, the electrical circuits, the extraction canopy and the ductwork above it - and each of those needs to be brought up to a standard you can defend. That means a Gas Safe commercial engineer commissioning and certifying gas appliances, an electrician confirming the electrical connection, and an extraction system that is clean enough to cope with the extra load. A tired second-hand fryer added to an already grease-heavy duct run is precisely the combination that fire risk assessments flag.

The good news is that none of this has to mean shutting your doors. A used unit can be installed, cleaned and signed off around your service, and the same discipline that keeps your extraction compliant applies here - which is why it pays to fold new kit into a planned maintenance rhythm rather than treating it as a one-off. If closures worry you, we cover how to keep the work moving in scheduling deep maintenance without closing the restaurant. Treat every second-hand purchase as a unit that starts dirty and starts unverified, get it cleaned and certified before it earns its keep, and the money you saved on the price tag stays firmly in your pocket.

Questions

Frequently asked questions

What paperwork should second-hand commercial catering equipment come with?

Gas appliances should carry a current CP42 commercial catering gas safety record, signed by an engineer who holds the commercial catering category on the Gas Safe Register. Refrigeration units should come with their F-gas service history, and all kit should show a UKCA or CE conformity mark on the data plate. If a seller cannot produce these, treat it as a red flag rather than a minor inconvenience.

Do I need to have used electrical equipment PAT tested before I use it?

There is no single law that names PAT testing, but anyone selling used electrical goods must supply something safe under the Electrical Equipment (Safety) Regulations 2016 and the General Product Safety Regulations. Before a second-hand unit goes into daily service you should carry out a visual check of the plug, flex and casing, then a portable appliance test. As the employer you carry the duty to provide safe equipment under the Health and Safety at Work etc. Act 1974.

Is it worth deep cleaning used catering equipment before I install it?

Yes. A used canopy, fryer or range almost always arrives carrying a heavy load of another kitchen's grease, which is both a hygiene problem and a genuine fire risk once it is added to your extraction system. A professional deep clean strips that deposit back to clean metal so the kit is safe, presentable and ready for an engineer to commission and certify.
